Year Ending December 31, 2017
Background
Ordinance No. 21 -11 amends the annual appropriations for the fiscal year ending December 31,
2017 in the General Fund and in various other funds to provide sufficient funding in certain budget
aCCOUntS.
Section 1 requests a fatal of $6,047,049 in funding authorization in the General Fund Of that
amount, $171,849 in funding is requested for reforestation. Funding is requested for tree
replacement fees available an January 1, 2017, Annually the account is reviewed, and funds not
spent from previous year's collections are rolled forward and appropriated. These funds are
generated from payments in lieu of tree replacement, and will be used to plant trees on public Ciry
property. Also in the General Fund, $5,869,200 is requested to make advances from the General
Fund to the Capital Construction Fund. As Ciry Council is aware, beginning in 2017 the City is now
budgeting far advances. The advances requested for funding authorization mostly cover the North
High Street widening project, and work on the Scioto River Pedestrian Bridge project as noted {n
Section 8 (below). These projects will be included in this year's bond package and be repaid with
the proceeds from the issuance of these bonds.
Initiating Department Department of Finance (section �)
Section 2 requests $40,000 in funding authorization in the Permissive Tax Fund for change order
#3 for the Churchman Road, Phase 2 project (Resolution 2116). The change order was
necessitated by the need for Trucco Construction Co. (the contractor} to perform work that was
unanticipated in the origins{ contract including relocating the existing monoliths at the southeast
corner of Cadman Drive and Churchman Road; adjusting three storm structures to grade;
installing a 10" concrete encased p {astir drive pipe at 1661 Rings Raad, and making adjustments
to the shared %use path at the northeast earner of Rings Road and Churchman Road.
Initiating Department; Department of Public Works (section 1)
Section 3 requests $230,000 in funding authorization in the Safety Fund for dispatcher salaries and

benefits related to the agreement with the City of Upper Arlington to provide dispatching services
for Police and Fire Departments as approved by City Council on March 13, 2017 in Resolution 14-
17. As City Council is aware, service for Upper Arlington will be under the control of the existing
Dublin management structure and will be housed at the Dublin Justice Center. In order to provide
service to Upper Arlington, six additional Communication Technicians and one Communications
Supervisor will be needed. Three Communication Technicians are expected to be hired by mid -
May, and the remaining three are expected to be hired by the beginning of October. Funding for
the supervisor position will be included with the 2018 Operating Budget. The funding requested in
this ordinance should be sufficient to cover the salaries and benefits for these new positions for
2017. If not, additional funding will be requested before the end of the year.
Upper Arlington will be billed for dispatching services utilizing the same billing formula that exists
currently for all participants (Hilliard, and Norwich Township). Washington Township is billed
under a separate agreement with the City.
Section 4 requests $5,470 in funding authorization in the Law Enforcement Trust Fund to pay fees
to other parties related to the forfeiture of assets seized in the course of Police investigations.
These fees cover court costs paid to the Franklin County Common Pleas Court, as well as
publication fees and a percentage of seized assets paid to the Franklin County Prosecutor's Office.
These costs are offset by revenue posted to the City's treasury from seizure of assets.
Section 5 requests $340,000 in funding authorization in the Wireless 911 Fund for the Next
Generation 911 (NG911) project approved as part of the 2017 -2021 Capital Improvements
Program. The NG911 capable phone system is an upgrade from the City's current system and will
accept text, pictures and videos, and interface to the statewide Emergency Services Internet (9 -1-
1) network. The full amount of the project is being requested in the ordinance, however the
Franklin County 9 -1 -1 Planning Committee is expected to reimburse the City for the costs directly
attributable to equipping eight answering positions to provide NG911. The exact amount of
funding to be received from Franklin County is not yet known, but is expected to be about 85% of
the cost of the project.
Initiating Department: Department of Finance / Po /ice Department (sections 3, 4, and 5)
Section 6 requests funding authorization in the Economic Development Bond Retirement Fund to
un- appropriate $36.80 in funding that was previously appropriated for interest on debt issuance.
This difference was due to rounding and will not be necessary for the scheduled interest payment.
Initiating Department: Department of Finance (section 6)
Section 7 requests funding authorization in the Capital Improvements Tax Fund to appropriate
money donated to the City by the Miracle League for the Darree Fields shade structure project.
The shade structures for the bleachers adjacent to the Miracle League Field are part of the overall
Darree Fields Capital Improvements Program. Early in the design process, the Miracle League
offered to partner with the City and donate $37,000 towards funding for this project. Work on
footings and rubber surface repair around them will be done in April with installation of the shade
structure being completed in late spring, depending on the manufacturing time frame.

were necessitated as part of the construction of the Service Center expansion project.
Palmetto Construction Services is the contractor for the project (Resolution 29 -16). These
change orders were necessary due to unforeseen changes including upsizing the HVAC
system from original specifications and associated ductwork changes, changes to the attic
insulation, a revision of the office configuration, adding additional door access controls,
enclosing soffits around exposed steel and infilling around the aluminum windows on the
second floor, additional framing to the gable ends of the roof trusses, pressure testing of
the existing sprinkler system, additional undercuts needed at the spread footings,
relocating an existing storm line that was in conflict with the installation of a new sanitary

east side of the site, and changing the interior glass to clear glass panels. This project is
still under budget as approved by City Council in the City's Five -Year Capital Improvements
Program.
• Funding of $1,017,480 is requested for costs related to park project for the Scioto River
pedestrian bridge and Riverside Park. Of that amount, $692,480 is requested for the
contract with Kokosing Construction Company, Inc. as approved by City Council in January
2017 (Resolution 06 -17) for the West Plaza Retaining Wall and Scioto River Pedestrian

or $152,350 represents the Scioto River Pedestrian Bridge west "abutment" portion, and
$540,130 represents the remaining Riverside Park "west plaza retaining wall" portion of the
work. $80,000 is requested for the contract with Innovative Contracting and Engineering
for the Scioto River Pedestrian Bridge Independent Cost Estimator Services. These services
include risk management support and comparative price estimating to help inform the price
for the award of the primary pedestrian bridge construction project. $75,000 is requested
for tree removal in preparation for the construction of the pedestrian bridge, and funding of
$170,000 is requested for pre- construction services for the pedestrian bridge project. In
December 2016, the City competitively selected and contracted with Kokosing Construction
Company, Inc. to work closely with the City and its design team to perform a series of
important pre- construction technical services such as constructability reviews, risk
identification, materials availability, cost projections, and refinements to the project
schedule. A memo dated March 9, 2017, titled Scioto River Pedestrian and Bicycle Bridge
and Riverside Park — Encumbrances and Expenditures Update was forwarded to City
Council in an informational packet and contains additional detail regarding the
aforementioned project costs for the pedestrian bridge and Riverside Park.
• Funding of $596,434.98 is requested for transfers. Of that amount, $418,138.56 is
requested for a transfer from the Capital Construction Fund back to the Capital
Improvements Tax Fund for reimbursement of expenses related to the Justice Center

Fund for utility burial costs that should have been paid from bond proceeds.
A portion of the projects listed above in Section 8 are funded through proceeds of bonds, most of
which have already been issued, and funds need to be moved to the proper accounts. This year's
bond package will include the North High Street Widening project, building renovations (with
exception of the Justice Center which debt has already been issued), and the Pedestrian Bridge
and Riverside Park projects.

Re. Scioto River Pedestrian and Bicycle Bridge and Riverside Park - Encumbrances
and Expenditures Update
Background
In order to better understand the fiscal relationship between the two projects, Dublin City Council
requested updated encumbrance and expenditure data for the Scioto River Pedestrian and Bicycle
Bridge and Riverside Park projects during the January 23, 2017 City Council meeting, Within the
City's Five Year Capital Improvements Program (CIP), the east and west plazas are included as
part of the Riverside Park (rather than the pedestrian bridge) because these plazas were
conceptually designed as part of the park master planning pracess, and they play such key roses in
the overall park design and programming The plazas and other proposed river park improvements
were approved by Council as part of the Scioto Riverside Park Master Plan in 2016, which planning
effort also provided the conceptual estimates for the park improvements programmed within the
City's approved Five -Year CIP, Staff has updated the cost information that was provided to City
Council on July 1, 2016. The purpose of this memorandum is to provide the requested cost
breakdown information related to current and recent Riverside Park and pedestrian bridge design
and construction, as well as to provide a brief summary of the funds that have been spent,
encumbered and programmed for these projects,
Scioto River Pedestrian Bridge Expenses and Encumbrances
Attached is a brief summary of expenditures and encumbrances to date related to the pedestrian
and bicycle bridge, from the project "s early conceptual design planning stages in 2013 through the
final design and Phase 1 construction,
Due to the pedestrian bridge`s size and the complexity of its unique, "s "curve, two span,
suspension bridge, with a teardrop shaped pylon, the Construction Manager at Risk (CMR) delivery
method, also commonly called Construction Manager�Generai Contractor, was selected for the
construction of the bridge project, This delivery method provides for the selection of a qualified
contractor through a transparent and competitive pracess during the design stage, In December
2016, the City competitively selected and initially contracted with Kokosing Construction Company,
Inc, far $110,000 to work closely with the City and its design team to perform a series of
important preconstruction services such as canstructabiliry reviews, risk identification, materials
availability, cast projections, and refinements to the project schedule,

March 9, 2017
Page 2 of 3
On January 23, 2017, Council approved a Guaranteed Maximum Price (GMP) contract with
Kokosing in the amount of $692,46840, which included the initial construction phase consisting of
the west plaza retaining wall and west bridge abutment. As noted in previous communications, the
early construction of these elements enabled the highly desired and beneficial construction
sequencing in this area to move forward and best facilitates the planned public and private work in
this area to proceed on schedule, Of this $6921 468,40 GMP Phase 1 contract, the Scioto River
Pedestrian Bridge west °`abutment " portion represents approximately 22 °lo of the total Phase 1
work, or $152,343,05, and the Riverside Park "west plaza retaining wall" portion of the work
represents the remaining amount The base work associated with the installation of the
foundations and wall structures for the retaining wall�bridge abutment is included in this Phase 1
construction effort, and the finishes will be added in later phases of the construction process,
In a companion effort designed to further mitigate cost risk, the City separately contracted with
Innovative Contracting and Engineering, an Independent Cost Estimator (ICE), to provide risk
management support and comparative price estimating using existing market conditions, The
amount of this contract is $79,986 The ICE's estimate is also being used to evaluate Kokosing's
proposed GMP pricing and to help inform the negotiation of the GMP for the award of the primary
construction contract,
The City also recently contracted with Russell Tree Experts in the amount of $74,990 to clear trees
at the bridge construction site, An early award of the contract was needed so the removal could
be completed prior to March 31St, as required by the applicable federal environmental regulations
associated with the United States Fish and Wildlife Service for the protection of the Indiana Bat.
The clearance area was determined after a careful assessment of the existing vegetation and the
minimally reasonable construction footprint of the bridge and its associated access requirements,
The proposed limits of construction were coordinated closely with Parks and Planning staff and
Vark planning consultant MKSK Studios, and were reviewed in the field with the contractor to
minze clearing where possible and to ensure the required space - including turning radii for the
truck delivering the crane - is cleared in advance of the deadline
Riverside Park Expenses and Encumbrances
Attached is a brief summary of expenditures and encumbrances to date related to the Riverside
Park Included in this breakdown (and by far the largest category of Riverside Park expenses to
date) are a number of land acquisitions of river fronting proper by the City, which have added
approximately 24 acres of new river fronting land to this park since late 2012,
As previously noted, an January 23, 2017, Council approved a GMP contract with Kokosing in the
amount of $692,468,40 far the initial construction phase consisting of construction of the west
plaza retaining wall and west bridge abutment Of this $692,468,40 GMP contract, the Riverside
Park west piaza retaining wall represents approximately 78 °/0 of the work, ar $540,125.35, and the
Scioto River Pedestrian Bridge west abutment (part of the bridge structure) represents the
remaining amount
Funding
Dublin City Council approved the Ciry's Five -Year CIP for 2017 -2021 on September 12, 2016, which
included 2017 funding in the amount of $22,750,000 for construction of the Scioto River

Page 3 of 3
Pedestrian and Bicycle Bridge and $9,400,000 for construction of the first phase of the Riverside
Park, The total amount currently programmed for the Riverside Park within the approved Five -Year
CIP is $19130010Oa.
The construction costs of these projects remain within budgets (and CIP programmed
investments) with the final design for the entire pedestrian and bicycle bridge nearing conclusion.
As the design of the first phase of the Riverside Park improvements advances focused heavily on
west and east plaza designs), updated estimates are being performed and should be completed
within the next few months,
As discussed during the 2017 -2021 CIP process, funding for the Scioto River Pedestrian Bridge and
the first phase of the Riverside Park construction is expected to come from the issuance of long-
term bonds, Staff is preparing a financing package that incorporates these two projects, which is
expected to be brought to Council for consideration in the spring. In the meantime, the funding
needed to meet these expenditures will be advanced from the City's General Fund. This advance
will be repaid with bond proceeds in the future.
Schedule
The projects remain on schedule, as construction of the pedestrian and bicycle bridge west
abutment and west plaza retaining wall began in early February and are anticipated to be
complete toward the end of May 2017, Tree clearing to allow for the bridge construction began the
week of February 20, 2017 and will be completed by March 31, 2017,
The pedestrian bridge design team has been working collaboratively tofinalize important design
details such as lighting. The lighting package includes all the illumination elements that were
approved by Council in July 2016. The elements include walkway, pylonLLeye of the needle,'keyhale,
pylon -base uplighting, hanger cable lighting wjcolor (RGB }ability and bottom of the bridge girder.
An updated rendering illustrating the lighting package is attached.
Staff anticipates bringing forward to Council a Phase 2 GMP contract to include the remainder of
the pedestrian and bicycle bridge structure construction on April 10, 2017.
The design of the first phase of park improvements (which includes substantial amounts of the
east and west plaza river park environments) is moving forward, although much of that
construction work (other than west plaza improvements) will begin only after the pedestrian bridge
construction nears completion, Staff expects to bring the final site plan for the west plaza before
City Council within the nett two months, This element of the Scioto River park plan is being
advanced first because of the need to fully coordinate its design and construction with the
numerous abutting public and private development projects.

Re; Resolution 06 -17 - Authorizing the City Manager to Enter into a Guaranteed
Maximum Price (GMP) Contract with Kakasing Construction Company, Inc,,
for the Construction of the West Plaza Retaining Wall and Scioto River
Pedestrian Bridge West Abutment (Phase 1) Project
Background
Dublin City Council approved the City`s Five -Year Capital Improvements Program for 2017.2021
an September 12, 2016, which included 2017 funding in the amount of $22,750,000 for
construction of the Scioto River Pedestrian and Bicycle Bridge and $9,400,000 for construction
of the first phase of Riverside Park, On July 5, 2016, Council affirmed the pedestrian bridge
alignment as connecting the proposed Rock Cress Parkway on the west side of the Scioto River
to Bridge Park Avenue on the east side of the river, as well as the associated landing plaza
locations for the bridge, and for the design to move forward, Council also affirmed an July 5,
2016 the need to advance the design and construction of a retaining wall for the new west side
landing plaza in order to better accommodate, and avoid conflicts among, a series of near term
planned construction projects in this immediate area, including the near term planned
construction of the pedestrian and bicycle bridge, the plaza itself, and the private development
projects being planned adjacent to the plaza, For a comprehensive discussion about the
background of the bridge, the attached memorandum dated July 1, 2016 is attached for
Council's reference,
Due to the size and complexity of this unique, "s "curve, twom span, suspension bridge with a
teardrop - shaped pylon, the Construction Manager at Risk, also commonly called Construction
ManagerJGenera! Contractor, delivery method is being utilized for the bridge project, This
delivery method provides for the selection of a qualified contractor through a competitive
process during the design stage, The City first contracts with the selected contractor to work
closely with the City and design team to perform a series of precanstruction services such as
canstructabilltyrevlews, identify risks, provide cast projections, and refine the project schedule,
Then the contractor and project owner endeavor to negotiate a Guaranteed Maximum Price
(GMP) far the construction contract(s), The City of Dublin selected Kokasing Construction
Company, Inc, as the contractor for the project,. and it is currently providing the anticipated
precanstruction services, A detailed memorandum to Council dated January 5, 2017 discussing
the delivery method and competitive contractor selection process is attached far Council's
reference,
Kokosing started its precanstruction sen�ices work in mid- December and has surveyed the site,
Memo re, GMP Contract with Kokosing for West Plaza Wall and West Abutment (Phase 1) Project
January 19, 2Q17
Page 2 of 3
reviewed the construction documents, participated in meetings with the design team, and is
providing the desired constructabilirylnput that will enable the City and design team to further
the project development, improve the plan quality, and proceed to construction. These services
are adding great value to the final design stages of the bridge.
The construction plans for the initial construction phase consisting of construction of the west
plaza retaining wall and west bridge abutment are complete and approved for construction, The
base work is included in this phase and the finishes will be added later, The work in this area is
being closely coordinated with the adjacent Bridge Park West Building Z, which is currently
under construction, and proposed Building Z2, Since the City now has the opportunity to have
the early wall and abutment construction performed by the likely bridge contractor (which is
clearly a benefit), Kokosing and the City have reached agreement on the GMP of $692,468,40
for this initial phase of construction, This price is approximately $80,000 under the amount
allocated for this work in the overall project's budget, and is consistent with other previous
estimates and proposals, Approval of the initial GMP contract will enable the highly desired and
beneficial construction sequencing in this area to move forward and will best facilitate the
planned public and private work in this area to progress on schedule,
Funding
As previously mentioned, funding was programmed in 2012 far the construction of the Scioto
River Pedestrian Bridge ($22,250,000) and construction of the first phase of Riverside Park
($914001000), Of this $692,468,40 GMP contract with Kokosing, the west plaza retaining wall
represents approximately 78 °la of this Phase 1 work, or $540,125,35, and the Scioto River
Pedestrian Bridge west abutment represents approximately 22 °% of this Phase 1 work, ar
$152,343,05.
As discussed during the 20172021 C1P review, funding for the Scioto River Pedestrian Bridge
and the first phase of the Riverside Park construction is expected to come from the issuance of
long -term bonds. Staff is preparing a financing package that incorporates these two projects,
which is expected to be brought to Council far consideration in the spring, In the meantime,
the funding needed to meet these expenditures wilt be advanced from the City's General Fund,
This advance wilt be repaid with bond proceeds in the future,
Construction Phasing and �chedul�
The construction of the project remains on schedule and within budgets as casts of the Phase 1
of the pedestrian and bicycle bridge construction have been determined and fnal design far the
entire bridge progresses. Construction of the Phase 1 improvements is anticipated to begin the
first part of February with a completion date of May 23, 2017,
Additionally, Kokosing has identified the benefits afpre- ordering the structural steel as soon as
February due to the anticipated lead time, construction phasing needs, and to reduce the risk of
future price volatility, The advanced structural steel procurement is being considered as a Phase
2 GMP contract, Finally, staff anticipates bringing forward to Council a GMP contract far the
third and final phase far the remainder of the bridge construction as early as March 2017,

Re: June 20, 2016 Council Workshop. Scioto River pedestrian bridge Follow-Up
Context
City Council held a public workshop on June 20, 2016, a portion of which included an update and extensive
discussion regarding the 30% detailed design LLengineering effort associated with the proposed Scioto River
pedestrian - bicycle bridge. 30% design is a customary plan submission and review stage for major
engineering projects and is when pier types and locations, alignment, abutment type and locations landing
points), bridge width and depth are established. The purpose of this memorandum is to provide additional
follow -up information related to that discussion, and to provide the Administration's recommendations for
moving forward. The memorandum will provide:
« Additional historical context for some of the key actions and decisions related to the pedestrian
bridge, as well as the identification of the financial investments made or contracted for to date;
« An assessment of the likely cost and schedule implications for the design and construction of a
taller main tower element within the suspension bridge portion of the bridge;
« Clarifications and recommendation regarding the bridge lighting;
« An identification and request for affirmation of key decisions associated with the pedestrian bridge
and other recently finalized planning efforts for several Bridge Street District public improvement
projects,
Back,�round
As described in the staff report distributed far the June 20 work session, the concept of the planned
pedestrian bridge formally emerged from the Scioto River Corridor Framework planning efforts in 2013.
Council had previously expressed interest in such a bridge after its visit to Greenville, South Carolina in
2009. EndreStudios was engaged as asub- consultant to MKSK Studios to explore this bridge idea as part of
a comprehensive Bridge Street District river corridor planning effort, and produced the first concept for the
pedestrian bridge, The initial MKSK River Corridor Framework plans also provided the first concept for the
proposed location for this bridge, connecting the east side of the river at a plaza within a new riverfront
park, and tying it into the west of the river by some type of new landing area along North Riverview Street,
just east of its intersection with North Street, as depicted below in an early concept from a Spring 2013
presentation.
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 2 of 12
From the concepts produced in this initial Scioto River Corridor Framework planning effort, the City quickly
advanced to the preparation of preliminary engineering in Spring- Summer of 2013 for all of the key public
projects identified in that planning effort, including the SR 161 /Riverside Drive Roundabout, Riverside Drive
realignment, the Dale - Tuller connector, and the riverfront parks and pedestrian bridge. The goal of the
preliminary engineering was to advance the planning for these projects to their next stage, prepare
preliminary cost estimates, and position the projects to move forward to design once programmed within
the City's 5 -year Capital Improvement Program (CIP). The projects were first programmed in the 2014 -18
CIP, which was approved by Council in September 2013. Preliminary engineering efforts were still in their
early stage at this time, so cost estimates were very conceptual, especially for the pedestrian bridge which
had a total cost allocation of $14.345M programmed in the 2014 -2018 CIP adopted by Council on
September 9, 2013. On September 16, 2013 Council held a workshop on the River Corridor Framework
Plan, during which the meeting minutes reflect Darren Meyer, lead project planner and urban designerfor
the River Corridor Framework Plan with MSKS, relayed:
"The bridge will be an approximately 700 foot span suspension bridge with a single
tower and an S- shaped deck. Architecturally, it will appear to be a light, open bridge, but
it actually needs to be a light bridge in terms of materials and cost in order to span 700
feet. Their architectural team is working through various 3D iterations of the bridge, all
of which include the cost. There are international firms that have a lot of experience with
this bridge type, including the San Francisco -based architect /engineer on their team.
When their core engineering team has developed the model for the bridge, it will be
handed off for a peer review by one of the international groups that has substantial
experience with these bridge types. There are several layers in the process, and
because it is a very unique structure, this is one of the more challenging parts of the
project. However, they have several excellent people on board to guide it."
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 3 of 12
The message from Mr. Meyeremphasized the amount of analysis and testingyetto be undertaken in order
to fully validate the concept, and meaningfully project its cost. Ateam was assembled in late 2013 to
furtheranalyze the pedestrian bridge, its constructability, performance, and its likelycosts, and included
EndreStudio, Burgess & Niple, Messer Construction, and Schlaich Bergermann & Partner, in addition to
ongoing engagement of the River Corridor Planning team (MKSK, EMH &T, etc.).
As this more in depth analysis of the pedestrian bridge piece of the River Corridor projects moved forward,
it became clear in early 2014 that the costs associated with building such a unique "s" curve suspension
bridge, over such a wide span, were becoming prohibitive. Similarly, as planning efforts along the west side
of the River advanced (including in depth studies of North Riverview Street), it also became increasing clear
that a landing plaza along the east side of North Riverview, at its intersection with North Street, was very
problematic and would have many undesirable attributes. These included:
• the lack of ADA accessibility due to the grade separation from North Riverview to North High Street
(12 feet),
• the possible impacts of and upon future redevelopment of private land along these roadways, and
to the future roadway design itself,
• the lack of good pedestrian connections to, and visibility from the landing plaza to High Street,
• the presence of numerous vehicular ways and access points adjacent to this plaza location,
• and the negative park impacts of protruding such a landing plaza and its support structure over the
steep hillside condition within the river park at this location.
Council was provided an in -depth update of all Bridge Street District projects at its 2014 Goal Setting
Session on February 28, 2014. At the Goal Setting Session, the Administration recommended six "next
steps" relating to those key public improvements within the Corridor which needed to move forward in
order for the River Corridor projects to proceed to implementation as Council desired, as follows:
Recommended 2014 Next Steps
Bridge Street District Public Improvements
1. Tuller Ridge -Dale Drive Connector: Design, ROW Acquisition & Construction

Next Step number "5" was in recognition of the ongoing budget and design challenges still facing the
bridge, which the Administration summarized in its presentation.
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 4 of 12
The Administration recommended at this Goal Setting Session a resolution seeking among other items, an
affirmation by Council to continue to explore cost savings options for Scioto River Pedestrian Bridge design,
while maintaining the goal of preserving the iconic bridge elements. On March 10, 2014 (and as an
outgrowth of its 2014 Goal Setting session), City Council approved Resolution 17 -14 (Attachment A), which
affirmed Council's direction to move forward as staff had requested with the key catalytic public projects
within the River Corridor, including the Pedestrian Bridge. In this Resolution Council reaffirmed its approval
of the Pedestrian Bridge concept and directed the Administration:
"Continue to evaluate and refine final design, costs and landing options for the Scioto River
pedestrian bridge, and develop alternatives for consideration as soon as possible."
The challenges still facing the City with establishing a yet -to -be determined acceptable west side landing
location, and to reduce project costs were acknowledged within the language of this resolution.
In mid -March 2014, staff tasked the bridge team (including Paul Endres and additional team members) with
finalizing its assessment of the pedestrian bridge, and defining the cost saving alternatives that could move
toward a more reasonable construction cost while maintaining the iconic appearance of the bridge that had
been presented. Among the key cost saving elements explored in this effort were the reduction of
suspended bridge span length, tower height, girder depth, bridge materials, and other design and
construction assumptions. It had been confirmed by this point, however, that the bridge span length was
one of the most significant cost drivers and that the span would need to be reduced to about 500 feet in
order to achieve meaningful cost reductions. Some amount of elevated pedestrian walkway would then be
used to complete the span of crossing the river valley. The project architect (Paul Endres), the City's
planning and urban design consultant (Darren Meyer with MKSK), as well as City staff, were all very
supportive of this approach.
The cost saving analysis for the suspension bridge portion of the pedestrian bridge was completed in July
2014, and staff discussions and refinements extended into Fall 2014. The total potential savings identified
by the bridge team at the time were estimated to be in excess of $4 million, but the team affirmed it had
preserved the desired original character of the iconic pedestrian bridge. The most significant
recommendations included a reduction in the length of suspension bridge span from a total length of 632
feet to 500 feet. In conjunction with this span reduction, a tower height of 83 feet was recommended by
the project architect as being appropriately scaled, and consistent with the iconic images that had been
previously shared. At this point in time, however, the west side bridge landing was still being examined, and
its final location would of course impact the final design and cost of the bridge. City Council approved its
2015 -2019 CIP on September 8, 2014 in Ordinance 78 -14, in which the total cost of the pedestrian bridge
was then programmed at $18.225M. Given the submission, preparation and review times associated with
the Five -Year CIP, the most current estimates generated by the review team at the time for the pedestrian
bridge were likely not fully reflected in the 2015 -19 CIP.
The west side bridge landing locations continued to be studied while the City was advancing and expanding
its overall west side planning efforts with assistance from the MKSK team (the landing location being one of
the key goals of that planning effort). These west side efforts also related to studies associated with the
new Dublin branch of the Columbus Metropolitan Library, the Bridge Park West project, needed roadway
enhancements in the area, and the on -going west side River Park planning. These comprehensive planning
efforts continued to move forward through the remainder of 2014 and early 2015 in tandem with the
ongoing refinement of the estimating and cost savings efforts associated with the pedestrian bridge.
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 5 of 12
Fortunately, the west side planning efforts did identify what eventually became the best and clearly
preferred west side plaza location which would serve as the landing area for the pedestrian bridge. The
preferred west side plaza location for the bridge landing, located just east of the intersection of Rock Cress
Pa rkway and North High Street;
• is fully aligned with the proposed Rock Cress Parkway (and its cycle track) to provide seamless
continuity to the Bridge Street District signature street system,
• provides a fully accessible pedestrian approach, at grade with North High Street,
• would have great visibility from, and interface with High Street, the new Library, its parking garage
and Rock Cress Parkway,
• is framed by active mixed -use developments including upper story residential units and ground
floor restaurants and outdoor seating,
• would not protrude into or negatively impact the sensitive river park areas,
• is sized and detailed to merge seamlessly with the fine - grained scale and quality of Historic Dublin
while allowing for open views to the pedestrian bridge, park and river.
At City Council Work Session on May 11, 2015 the Administration and consulting team provided Council
its most comprehensive update on the outcomes from these west side planning efforts, with the primary
focus of the session being on the planned improvements associated with the library and the relationship of
those improvements to other City projects on the west side of the River, including the pedestrian bridge
and its landing plaza.
The above slide from the May 11, 2015 presentation depicted the new location for the landing area,
showing the bridge's shift north, and the slide below began illustrating the concept of the 500 feet long
suspension bridge connecting to the new west side plaza via an elevated walkway.

The results of the cost saving analysis and the finalization of the landing points helped facilitate the most
informed projected cost estimates to date and were used as the basis forthe City's most recently approved
Five -Year CIP presented in August of 2015. This current approved 2016 -20 CIP includes a total project cost
estimate forthe pedestrian bridge of $22.438M, with an estimated construction cost of $19.21M. These
budget figures provide the basis upon which the current design efforts of the TY Lin final design team have
been authorized to move forward.
The west side landing area plaza location was further confirmed in the final version of the Bridge Park
Development Agreement, authorized in Ordinance 44 -15 in August of 2015, wherein provisions were added
to specifically include an obligation of the developerto provide the new plaza location to the City of Dublin
at no cost. This location was also also presented as part of Council's 2016 Goal Setting session on March
11, 2016 as part of a BSD update, during which staff reconfirmed that this location decision had been
finalized. The plaza and bridge landing location were most recently affirmed as part of Council's formal
approval of the Scioto River Master Park plan on May 23, 2016.
There was also some discussion at the June 20, 2016 Work Session regarding the pedestrian experience
while crossing the bridge. The project's lead planner and urban designer, Darren Meyer with MKSK,
described it as follows:
The pedestrian bridge experience is comprised partly of the bridge architecture and largely of the
river and surrounding park. The scale and natural beauty of the Scioto River corridor is a defining
feature of the experience of crossing the pedestrian bridge. Given the significant role of the river
and park environment in the experience of the pedestrian bridge, the views from the bridge will be
dynamic — always changing with season, time of day and atmosphere.
The western side of the river is largely a flat floodplain meadow several hundred feet in width that
climbs quickly as you approach North Riverview and High Street. This area was formerly agricultural
land through the mid -20`^ century and has since reverted to a naturalized environment, though one

with a significant presence of invasive plant species. The proposed park design, and the views from
the pedestrian bridge as you move eastward from Historic Dublin, will be defined by naturalized
plantings: taller meadow grasses, selective understory trees and shrubs and the perseveration and
re- establishment of a wooded floodplain. Views across the river along the pedestrian bridge length
will be selectively cleared and maintained to allow dramatic vistas while preserving, where feasible,
legacy trees and mature vegetation. Trails and park amenities in the floodplain meadow will be
sensitively placed to allow access to the river and natural areas without significantly disturbing the
pastoral effect.
The architecture of the pedestrian bridge itself - deck, railing, and substructure — will be consistent
from west landing to east landing, accented around the river channel by the suspension cables and
main tower. The location of the main tower was designed to sit as near the river channel as
possible to maximize views of this iconic element from all vantage points. The landings at either
end of the pedestrian bridge will provide a transition from the largely linear movement of bridge
users to a wider community gathering space and continue the high architectural quality of the
bridge and adjacent built environment.
The graphic below depicts the current extent of the suspension bridge, the section of elevated walkway,
and the plaza locations.

Council also requested staff provide cost information related to pedestrian bridge planning, design and land
acquisition to date. That summary is provided as Attachment B.
Providing a Taller Tower Element -Cost and Schedule Implications
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 8 of 12
At the June 20, 2016 Work Session there was extensive discussion regarding the potential desirability of
increasing the height of the main tower element on the proposed pedestrian bridge. One point of
clarification at this point; the tower heights being referred to during that discussion actually refer to the
height from the top of the bridge's walking deck to the top of the tower (not to the height of the tower as
measured from the ground). So, for the 30% design summary presented to Council at the meeting, the
height from the bridge deck to the top of tower was 83 feet, and the height of the tower from the ground
was actually 132 feet.
As noted earlier, the most meaningful cost saving element identified as part of the 2014 bridge cost saving
efforts was the reduction in the length of suspension bridge span, wherein the final reduction had gone
from a total suspended length of 632 feet to 500 feet. The total bridge length (suspension bridge and
elevated walkway) is 760 feet. In conjunction with this span reduction, the project's architect, Paul Endres
recommended a corresponding tower height of 83 feet as being appropriately scaled and preserving the
iconic nature of the overall design. The bridge team and the Administration concurred with the project
architect's recommendations at that time and all agreed the 2014 cost saving efforts had met the
objectives of maintaining the unique and iconic design of the bridge while resulting in a more refined and
acceptable cost estimate. These efforts had been completed by the time the Administration provided its
comprehensive update at Council May 11, 2015 Work Session, as noted in the minutes:
"The pedestrian bridge analysis was done previously, and the City is initiating negotiations for the
final design of thatfacility."
The estimates resulting from the cost saving efforts were used in establishing the cost estimates set forth in
the 2016 -2020 CIP, and helped frame the parameters that were provided as part of the scope for the design
and permitting phase services. Staff eventually conducted a formal, competitive, selection process in the
fall of 2015 to select the team for the design and permitting phase services for this project. As a result of
this process, the team led by TY Lin International (TY Lin) was engaged. Paul Endres is continuing in the role
as project architect, to help ensure continuity of the design concept. As was noted during our presentation
at the June 20, 2016 Work Session, staff believes that the City has an extraordinarily talented, experienced
and well equipped design team to carry out the design and permitting of this critical project.
During the initial stages of recent final design (the 30% design effort recently reviewed by Council), the
project architect began to develop some concerns with his previous height recommendation as the impacts
of all of the planning and design parameters were becoming increasingly evident. Among those concerns
was a determination that the actual walking deck was, by necessity, becoming more elevated within the
"keyhole" of the main tower, thereby resulting in a more compressed appearance for the above -deck tower
height of 83 feet. Council shared some of those same concerns at the June 20, 2016 Work Session and
requested staff assess the cost and schedule impacts of including the tower element at an above -deck
height of 110 feet consistent with the original concept.
Staff has worked with the TY Lin design team and concur with the team's findings that the primary tower
height can be increased from its currently designed above -deck height of 83 feet (overall total tower height
is 132 feet) to an above -deck height of 110 feet (total height is 169 feet) for approximately $500,000,
inclusive of all design ($150,000) and construction ($350,000) costs. The suspended span length would
remain unchanged at 500 feet. Staff also concurs the pedestrian bridge will be enhanced visually by such a
height adjustment, both in terms of the pedestrian experience on and near the bridge, as well as when
being viewed from a distance.
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 9 of 12
So long as the design change process is initiated immediately, the schedule is anticipated to result in an
additional three (3) months of design and review time, extending the projected design completion from late
November 2016 to February 2017. Team members will endeavor to compress this time frame, if possible.
The exact impacts of the increased design time on construction timing is less clear. The team believes the
increased tower height could result in an additional 2 months of construction time, subjecting the project
to an additional winter season, and extending the completion date from the currently planned October
2018 to May 2019. Substantial completion of the bridge could potentially be feasible by the end of 2018 but
is very much dependent on many factors.
As was emphasized at the June 20 Work Session, as the design efforts progress, so does the environmental
coordination and permitting — primarily with the United States Army Corps of Engineers ( USACE), Ohio
Department of Natural Resources (ODNR) and Federal Emergency Management Association (FEMA). The
two major permits associated with this project are federal permits that must be obtained from the USACE
for work in wetlands and the river and from FEMA for potential impacts to flood elevations. Regardless of
the proposed tower height change, the permitting will likely be the controlling factor driving the critical
path schedule for the beginning of construction. Other factors that will likely impact the schedule include
weather, steel availability, and adjacent construction activities in the area such as the plazas and other
private development projects. As we continue to advance toward 60% design, and more details are
included in the plans, we will gain additional information that will further inform our permitting and
construction schedule.
Clarifications and Recommendation Regarding Bridge Lighting
City Council has previously expressed interest in the manner in which the new pedestrian bridge will be lit.
Although not schedule sensitive at this point, Council did receive an overview of current lighting level
options for the new pedestrian bridge at its June 20, 2016 Work Session. Three lighting options are
summarized as follows:
Lighting Level

Cost

The design team has provide additional detailed information regarding those lighting levels and that
memorandum is provided as Attachment C.
Staff has reviewed the options and concurs with the TY Lin team's recommendation that Council authorize
the Intermediate option. This level of lighting will add visual interest to the entire bridge structure. For the
hanger cables the Intermediate level of lighting gives the City the flexibility to program custom color
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 10 of 12
changing lighting sequences. The ability to program basic color shows provides more than enough lighting
to highlight the bridge at night and further provide flexibility during select special events.
Budget Implications and Moving Forward
Based on the 30% design of the pedestrian bridge with an above -deck tower height of 83 feet, Base Lighting
Option, 18 month schedule and concrete piers, the estimated construction cost is $19,600,000. Increasing
the above -deck tower height to 110 feet and incorporating the Intermediate lighting option the estimated
additional construction cost is approximately $900,000, for a total estimated construction cost of
$20,500,000. This compares to the current CIP construction estimate of $19,210,000. In addition to the
increased construction costs summarized above, the TY Lin team estimates additional design fees for the
increased tower height to be approximately $150,000.
As we continue to advance toward 60% design, and more details are included in the plans, we will gain
additional information that will further refine the construction cost estimate. A typical construction
contingency assumption for a non - complex bridge is around 10% at this stage of design. The above -
referenced construction estimates currently include 9% contingency. For this type of complex and unique
bridge a higher contingency such as 20% may be reasonable at this stage of design which would result in a
total estimated construction budget of $22,750,000. This contingency could then be reduced to 15% at 60%
design. There are many unforeseeable factors that could impact the cost including material price
escalations, availability of unique bridge elements in the domestic market (main suspension cable, bearings,
dampers, etc.), the competitive bidding environment, availability of local /regional contractors with the
experience to build this complex bridge, etc. However, only the formal bidding process will address the
accuracy of all assumptions and considerations made in the engineering estimates.
From the Administration's perspective, we believe the following summarizes the current project status and
the Administration's recommendations for moving forward:
• The current location of the pedestrian bridge, and its recommended landing locations continue to
represent the best available locations and should remain as planned and designed.
• The Intermediate lighting level provides an excellent, cost effective lighting option which will add
visual interest to the entire iconic bridge structure and give the City the flexibility to program
custom color changing lighting sequences.
• Increasing the tower height from the current above -deck height of 83 feet to the proposed above -
deck height of 110 feet will improve the appearance of the bridge both when viewed in near
proximity and when seen from a distance. Given the objective to create what will likely become
Dublin's most iconic public project, and the relatively modest budget and time impacts of the
change, the Administration recommends increasing the above -deck tower height to 110 feet.
• Council affirm these decisions on July 5, 2016 in order to minimize the impacts upon the project's
schedule
Affirmation of Key River Corridor Public Improvements
On a related matter, in March 10, 2014 Dublin City Council approved Resolution 17 -14, entitled "A
Resolution Affirming Key Public Infrastructure Improvement Projects in the Scioto River Corridor Area of
the Bridge Street District and Directing the Administration to Proceed with the Final Design of Various
Public Improvements" (Attachment A). The purpose of this resolution was to formalize and establish the
clear intent of Council regarding a series of public improvements projects which had been extensively
Memo re. June 20, 2016 Council Workshop: Scioto River Pedestrian Bridge Follow -Up
July 1, 2016
Page 11 of 12
planned and publicly reviewed over the previous months, so that the final engineering and design of the
projects could move forward, as well as to make clear to all stakeholders that these location decisions for
these projects had been finalized.
Since that time, the City has continued to advance its planning efforts along this corridor, most notably in
connection with the library redevelopment and west side area planning, as well as the Scioto River Park
planning. Many of these projects, and their time requirements for implementation, were reviewed with
Council at its annual Council retreat on March 11, 2016, as well as in other forums. The Administration
believes that in order to ensure that a series of pending public improvement projects in this area can
confidently move forward in a timely and well- coordinated fashion, and that City Council is aligned with the
Administration's actions in moving these forward, we request that City Council take a similar action for
these more recently planned projects in order to affirm the appropriateness of, and need for these projects
moving forward.
We would request that by motion, Council affirm:
• The current pedestrian bridge alignment, the landing plaza locations for the bridge, the
Intermediate lighting package as presented, and the increase in the bridge's tower above -deck
height to 110 feet are approved, and the design for all of these should move forward.
• The alignment and location of the North Riverview extension from North Street to North High
Street (opposite Indian Run Drive), as depicted in the recently approved Scioto River Corridor Park
Plan and page 7 of this memo, is affirmed and its construction should move forward immediately.
• The general alignment of the new roadway system which creates the new "block" where the new
library facility and parking garage will be constructed (see Attachment D); consisting of Rock Cress,
Franklin Street, North Street and North High Street; and the general location of the new library and
the parking garage facilities on that block; with the timing of the design and construction of these
facilities to be coordinated and advanced in tandem with the agreements and collaborative efforts
finalized with the Columbus Metropolitan Library and the Dublin City School District.
• The need to advance the design and construction of a retaining wall for the new west side landing
plaza (as depicted below) in order to better accommodate the future construction of the pedestrian
bridge, the plaza itself, and the private projects being planned adjacent to the plaza.
o As was discussed in Council's 2016 Goal Setting Session in March, there is, and will continue
to be, a great deal of construction activity taking place in the northern portion of the
Historic District over the next few years (pedestrian bridge /elevated walkway, plaza, Bridge
Park west —north and south of plaza, North Riverview extension, North High Street
reconstruction, and all the improvements associated with the redevelopment of the new
library). This retaining wall (estimated to cost about $500,000) will support both the
eastern end of the new west side plaza and the western terminus of the elevated
pedestrian walkway, and because of required construction sequencing and staging, will
need to be constructed in the near future. The appropriation for this improvement (based
on an estimate) is included in the supplemental appropriation being considered by Council
on July 5, 2016.

Memo
Re: Resolution 17 -14 Affirming Key Public Infrastructure Improvement Projects in the
Scioto River Corridor Area of the Bridge Street District and Directing the
Administration to Proceed with the Final Design of Various Public Improvements /
Bridge Street District Follow Up Items
Background
At the February 28 Goal Setting Retreat, Council discussed a number of items related to planned
public projects and emerging private development opportunities in the Bridge Street District.
Council members expressed interest in scheduling one or more work sessions to review additional
information, discuss remaining policy questions and provide further direction to staff as
implementation efforts proceed. This memo outlines the major topics for consideration as follow up
discussion items and provides recommendations on prioritization and timing for addressing these
topics.
Design Expectations
Council expressed a desire to develop tools and /or processes to help better communicate and align
Bridge Street District planning and design expectations among key participants in the development
process (project developers /designers, staff, Planning and Zoning Commission and Council). Staff
recommends that Council hold a work session to establish shared expectations for project design
and architecture in key locations within the Bridge Street District. To provide clear and timely
direction for applicants currently moving through the development review process and for others
interested in pursuing near term development opportunities, staff recommends a work session be
held as soon as is convenient for Council. Staff will be prepared to offer potential meeting dates for
Council's consideration at the March 10"' Council meeting.
Project Review for Development Agreements
Due to the amount of public street infrastructure necessary to create the grid system in the Bridge
Street District, most of the key private development projects will require partnerships with the City
in order to move forward. City Council will thus have substantial discretion to provide significant
oversight regarding which projects achieve the City's goals and vision for the BSD and therefore
should be advanced through City partnership. For this reason, it is appropriate to ensure early
Council understanding and general support of proposals that will involve development agreements
with the City, prior to extensive planning and design investment by prospective applicants.
Opportunities for such Council input and reaction are not currently provided within existing
development review procedures for the BSD. To facilitate an efficient and predictable review
Memo re. Bridge Street District Work Sessions
March 6, 2014
Page 2 of 2
process, staff will prepare options to better incorporate Council into the early stages of the
process, and will present these for Council's consideration at an upcoming meeting.
As noted above, because there are currently development applications moving through the
established review process, staff recommends that City Council schedule a work session in the
coming weeks, in lieu of a more formal Council review process that will be proposed.
Public Projects
At its Retreat, Council discussed the scope and timing of major public infrastructure improvements,
primarily located in the Scioto River Corridor planning area, as well as other portions of the street
network that will be constructed with individual private development projects. As part of that
discussion, Council directed staff to prepare a resolution affirming key public infrastructure
improvements and directing the Administration to proceed with final design of those projects.
Resolution 17 -14 is attached to this memo for Council consideration.
In addition, staff will provide information at future meetings on the progress of other facets of
planned public improvements planning efforts, including:
• An overview of the Bridge Street District Transportation Phasing Plan (nearing completion)
• Illustrative simulation showing how the Riverside /SR 161 roundabout will function
• Creation of streetscape character and furnishings standards for new streets in the BSD (this
is necessary to complete the final design of the new public streets)
• Additional refinement of the pedestrian bridge design and potential construction methods
• Maintenance of traffic plans related to the realignment of Riverside Drive and construction
of Riverside /SR 161 roundabout
• Remaining land acquisitions need to construct new roadways
Staff recommends presenting this information as it becomes available as an agenda item at regular
Council meetings. If Council prefers, separate work sessions can subsequently be scheduled to
focus on one or more of these items in greater depth.
Recommendation
Staff recommends adoption of Resolution 17 -14 at the March 10"' Council meeting. Staff also
recommends Council schedule its first work session within the next month to provide timely
direction of architectural and design expectations for pending development proposals. Staff will
follow up with additional information regarding the other items noted in this memo, and will
schedule additional work sessions as directed.

Re: Iconic Scioto River Pedestrian Bridge — Aesthetic Bridge Lighting
(Follow up to 06120116 Public Meeting)
Introduction
Lighting Design Alliance (LDA), along with T.Y. Lin International Group (TYLI) and
Endres Studio (ES), have coordinated a Lighting Design Package for the Iconic Scioto
River Pedestrian Bridge for the City of Dublin (City). The Package consists of three (3)
Levels of Aesthetic Lighting which consist of; (A) Primary Level, (B) Intermediate
Level, (C) Digital Level. The three levels are summarized below as agreed upon by TYLI,
ES, and the Project Team.
A. Primary Level
The features of the Primary Level of lighting is presented below:
1- Walkway /Handrail LED Lighting
2- Upper Pylon Keyhole lighting
3- Lower Pylon Keyhole lighting
4- Linear strip - lighting along the vertical pylon element
5- Floodlights near ground level for Pylon Primary
The estimated cost for the Primary Level of lighting is approximately $178,000 which
includes the cost for light fixtures, lighting control system, installation, materials,
fixture supports, wiring, power supplies and drivers, etc.
B. Intermediate Level
The Intermediate Level of lighting includes all elements identified in the Primary Level
listed above, as well as the following:
1- Hanger Cable Color Changing Lights
THE Uxxnxx Nrnxx 2- Linear Box Girder Up- Lighting
uwGNE, Mx.
LOS ANGELES

C. Digital Level
The Digital Level of lighting includes all elements identified in the Primary Level and
Intermediate Level as listed above, with the modification of Hanger Cable Lighting as identified
below:
1- Low Resolution Digital Lighting in replacement of Hanger Cable Color Changing Lights
The estimated cost for the Digital Level of lighting (which includes the Intermediate Level and
Primary Level cost) is approximately $1,300,000 which includes the cost for light fixtures,
lighting control system, installation, materials, fixture supports, wiring, power supplies and
drivers, etc.
Recommendation
It is the recommendation of the Project Team and LDA to the City to implement the
Intermediate Level of Aesthetic Bridge Lighting. This Level of lighting will add visual interest to
the entire bridge structure from the Primary, all the way up the highest point of the needle
element of the Pylon. For the hanger cables the Intermediate Level of lighting gives the City
the flexibility to program custom color changing lighting sequences. The ability to program
basic color shows provides more than enough lighting to highlight the bridge at night and
further provide flexibility during select special events.
We do not recommend the Digital Level of Aesthetic Bridge Lighting as it comes at a significant
cost to the Project which is not worth the marginal increase in programmability for each of the
hanger cable lighting fixtures.
The three levels of lighting (Primary, Intermediate, and Digital) are described in further detail
in the following pages labeled "Aesthetic Lighting Level Detail' which identify key aspects of
each lighting element including a descriptive narrative of lighting intent to the use as well as its
location, programmability, maintenance and access, service life, and fixture costs.
pg. 2
AESTHETIC LIGHTING LEVEL DETAIL
A. Primary Level
The Primary Level lighting consists of lighting the features of the bridge the group identifies as
essential for the bridge to be used during evening and night hours. The Primary Level provides
Walkway and Pylon illumination including the bottom (below deck, vertical (above deck) and
"keyhole' features. Detailed discussion for each lighting element is provided below:
1- Walkway /Handrail LED Lighting:
• LED strip - lights are integrated into the handrail on each side of the bridge along
the entire span of the walkway with a mounting channel, angle, and optics to
direct light out to illuminate the entire width of the walkway.
• Create a safe environment for pedestrians to walk and enjoy the bridge.
• Fixtures to be operated with an astronomical time clock to only be operated
during evening and nighttime, when illumination is needed. As the fixtures are
for safety lighting, we are recommending the fixtures to be at a high consistent
light output to be operated from dusk until dawn.
• For fixture life, we are estimating that the linear strip - lights to have an estimated
10 year life of the fixture itself, and 5 years life of the drivers with minimal
maintenance to the fixtures.
• The fixture locations make them very easy to maintain from the deck. The
fixtures will have remote drivers, so these would have to be located in an
accessible location in the deck that has a well ventilated and waterproof
enclosure.
• The current year costs for these light fixtures are estimated to be $76,000 not
including labor and incidentals to install /replace the fixtures.
2- Upper Pylon Keyhole Lighting (Illuminates inner top portion of the needle from lights
installed in the bridge deck):
• Fixtures will be recessed in the walkway of the bridge, only along the center area
under the archway, illuminating upwards to light the inner surfaces of the
structure.
• The benefit to the fixtures being recessed in the walkway is they will provide a
clean lighting design by not having the light fixtures visible.
• Fixtures to be operated with an astronomical time clock so that the fixtures turn
on during the start of the evening and turn off when the sun is out. As the
fixtures are more decorative lighting, we are recommending the fixtures to be
set to two different light outputs. From dusk until lam we recommend a high
light output. From lam until dawn we recommend the fixtures to be set to a low
light output, as there will be fewer people experiencing the bridge at these
times, and it will save on energy usage and will increase the life of the fixtures.
pg. 3
• The fixture locations make them very easy to maintain from the deck. The
fixtures will have integral drivers, so to maintain the drivers, the top of the
fixture will have to be able to be removed from above for access.
• For fixture life, we are estimating that the up -light fixtures have an estimated 15
year life of the fixture itself, and 5 year life of the driver with minimal
maintenance to the fixtures.
• The fixture locations make them very easy to maintain from the deck. The
fixtures will have integral drivers, so to maintain the drivers, the top of the
fixture will have to be able to be removed from above for access.
• The current year costs for these light fixtures are estimated to be $9,800 not
including labor and incidentals to install /replace the fixtures.
3- Lower Pylon Keyhole lighting (Illuminate the inner, bottom portion of the needle from
lights installed in the bottom sides of the box girder):
• Fixtures will be recessed within the bottom portion of the box girder illuminating
downwards to light the inner surfaces of the structure.
• The benefit to the fixtures being recessed in the box girder, is that they will
provide a clean lighting design, by not having the light fixtures visible.
• Fixtures to be operated with an astronomical time clock, so that the fixtures turn
on during the start of the evening, and turn off when the sun is out. As the
fixtures are more decorative lighting, we are recommending the fixtures to be
set to two different light outputs. From dusk until lam we recommend a high
light output. From lam until dawn we recommend the fixtures to be set to a low
light output, as there will be fewer people experiencing the bridge at these
times, and it will save on energy usage and will increase the life of the fixtures.
• For fixture life, we are estimating that the up -light fixtures have an estimated 15
year life of the fixture itself, and 5 year life of the driver with minimal
maintenance to the fixtures.
• For maintaining the fixtures, as they are below the deck, inside of the box girder,
we recommend having an access panel at the top of the deck to go inside the
structure if necessary to maintain the fixtures and integral drivers.
• The current year costs for these light fixtures are estimated to be $8,400 not
including labor and incidentals to install /replace the fixtures.
4- Linear Strip- Lighting along the Vertical Pylon Element (Illuminate the vertical channel
of the needle element by having a light channel on both sides of the vertical opening):
• Linear LED strip -light will be mounted in that channel to illuminate the face of
the vertical surface.
• Creates a clean line of light that will accent the architecture of the pylon form.
• Fixtures to be operated with an astronomical time clock, so that the fixtures turn
on during the start of the evening, and turn off when the sun is out. As the
fixtures are more decorative lighting, we recommend the fixtures to be set to
pg. 4
two different light outputs. From dusk until lam we recommend a high light
output. From lam until dawn we recommend the fixtures to be set to a low light
output, as there will be fewer people experiencing the bridge at these times, and
it will save on energy usage and will increase the life of the fixtures.
• For fixture life, we are estimating that the up -light fixtures have an estimated 15
year life of the fixture itself, and 5 year life of the driver with minimal
maintenance to the fixtures.
• For maintaining the fixtures, as they are located along the entire vertical height
of the main needle element, the fixtures themselves would have to be accessed
by use of a man -lift, or equivalent, to reach the higher fixtures. The fixtures will
have remote drivers, so these would have to be located in an accessible location
in the deck that has a well ventilated and waterproof enclosure.
• The current year costs for these light fixtures are estimated to be $8,700 not
including labor and incidentals to install /replace the fixtures.
5- Floodlights near Ground Level for Pylon Primary (Illuminate Primary of Pylon "Needle"
Element):
• Provides adjustable floodlights, mounted at the Primary of the center structural
pylon, to up -light the Primary.
• As the pylon is located near the river's edge, the design team recommends
raising these fixtures on an inverted column on both sides of the pylon, where
we would mount adjustable floodlights to illuminate the structure.
• Fixtures to be operated with an astronomical time clock, so that the fixtures turn
on during the start of the evening, and turn off when the sun is out. As the
fixtures are more decorative lighting, we are recommending the fixtures to be
set to two different light outputs. From dusk until lam we recommend a high
light output. From lam until dawn we recommend the fixtures to be set to a low
light output, as there will be fewer people experiencing the bridge at these
times, and it will save on energy usage and will increase the life of the fixtures.
• For fixture life, we are estimating that the up -light fixtures have an estimated 15
year life of the fixture itself, and 5 year life of the driver with minimal
maintenance to the fixtures.
• For maintaining the fixtures, as they are located at the Primary of the pylon, in
the planting area, the column locations will have to be coordinated in the field.
There is also the potential for the column locations to be in areas where there
could be water around it, so that might impact the accessibility of maintenance
for the floodlight fixtures.
• The current year costs for these light fixtures are estimated to be $10,800 not
including labor and incidentals to install /replace the fixtures.

B. Intermediate Level
The Intermediate Level lighting consists of all elements identified in the Primary Level above as
well as the additional features summarized below. The Project Team and LDA strongly believe
the Intermediate Level will be influential in creating a strong visual feature at night but not as
influential and important as the features associated with the Primary Level. Not every element
has to be implemented in the final design, but we recommend including as many of the
elements as possible as we understand one of the goals of this Project is to maximize the
overall night time visual interest in varying ways.
1- Hanger Cable Color Changing Lights:
• The most impactful visual element is the linear LED strip -light fixtures that will be
mounted to the front and back sides of the each vertical hanger cable
(approximately 38 cables).
• The vertical fixtures creates a strong lighting element that can be enjoyed by the
pedestrian level experience, but it will be even more impactful when viewed
from a distance.
• The lighting feature helps further activate the bridge at night, highlighting even
more of the unique design elements of the structure.
• The fixture is a dynamic color changing fixture which integrates a Red, Green,
and Blue (RGB) — module into the fixture. We recommend the fixture to be
placed on the front and back side of each of the 38 hanger cables.
• Provides the City with a flexible system to create color shows. These
shows could include color fades, color chasing, radiating color from the
center or sides, etc. Additionally the City also has the option to have the
bridge illuminated in a static color, for holiday lighting (e.g. green and red
for Christmas, orange for Halloween), school or team colors, or for
certain remembrances (e.g. pink for breast cancer awareness month).
• Color variations for this approach only occur in horizontal patterns
among the cable strands, but is fully programmable by using a DMX
system.
• Fixtures to be operated with an astronomical time clock through a DMX system,
so that the fixtures turn on during the start of the evening, and turn off when the
sun is out. As the fixtures are more decorative lighting, we are recommending
the fixtures to be set to two different light outputs. From dusk until lam we
recommend a high light output. From lam until dawn we recommend the
fixtures to be set to a low light output, as there will be fewer people
experiencing the bridge at these times, and it will save on energy usage and will
increase the life of the fixtures. The DMX system would run the different
programmed sequences once turned on from the astronomical time clock.
• For fixture life, we are estimating that the strip -light fixtures to have an
estimated 15 year life for the fixture itself, and a 5 year life of the driver with
minimal maintenance to the fixtures.
pg. 6
• For maintaining the fixtures, as they are located along the entire vertical height
of the hanger cable, the fixtures themselves would have to be accessed by use of
a lift to reach the higher fixtures. The fixtures will have remote drivers, so these
would have to be located in an accessible location in the deck that has a well
ventilated and waterproof enclosure.
• The current year costs for these light fixtures are estimated to be $85,600 not
including labor and incidentals to install /replace the fixtures.
2- Linear Box Girder Up- Lighting
• To create an even lighting effect on the underside of the box girder, we
recommend a continuous light channel suspended from the bottom of the box
girder.
• The channel will follow the curve of the bridge. The lens of the fixture will be
facing upwards to light the underside of the element from a single light source.
• The fixture gives additional visible light to the structure, as we are creating an
illuminated vertical surface that will highlight the structure of the bridge below
the deck. It will also help define the bottom of the bridge in the space, so that it
does not appear like the hanger cables and the needle element are floating in
the visual space.
• It will give visual interest to the bridge when viewed from afar, as the
overall surface will be visible from views from afar.
• It will also be visible when you walk across, as the bridge is curving in
front of you, which will give you views of the lighting effect.
• Fixtures to be operated with an astronomical time clock, so that the fixtures turn
on during the start of the evening, and turn off when the sun is out. As the
fixtures are more decorative lighting, we recommend the fixtures to be set to
two different light outputs. From dusk until lam we recommend a high light
output. From lam until dawn we recommend the fixtures to be set to a low light
output, as there will be fewer people experiencing the bridge at these times, and
it will save on energy usage and will increase the life of the fixtures.
• For fixture life, we are estimating the strip -light fixtures to have an estimated 15
year life for the fixture itself, and a 5 year life of the driver with minimal
maintenance to the fixtures.
• Fixture maintenance - as they are located along the entire bottom portion
suspended below the box girder, they will be difficult to maintain. The underside
of the box girder would have to be cleaned eventually, so we anticipate that
there would be a system put in place of a window - washing type apparatus put in
place that could give access below the bridge. The fixtures will have remote
drivers, so these would have to be located in an accessible location in the deck
that has a well ventilated and waterproof enclosure.
• The current year costs for these light fixtures are estimated to be $266,000 not
including labor and incidentals to install /replace the fixtures.
pg. 7
C. Digital Level
The Digital Level lighting consists of all elements identified above in the Primary Level and
Intermediate Level's, however the difference would be using a Low Resolution Video solution
in place of the RGB Hanger Cable Lighting.
1- Low Resolution Digital Lighting:
• The Digital lighting option would integrate a Low Resolution Video solution onto
the front and back side of each of the 38 hanger cables in place of the RGB
Hanger Lighting as described in the Intermediate Level.
• Low Resolution Video solution provides the city with a very flexible system to
create higher level shows than the RGB color changing system.
• Shows could include scrolling letters (e.g. team name scrolling across the
cable strands or other images moving across the bridge), it could have
moving shapes and pattern sweeps, star bursts, etc.
• Reliability: given the variable angles and length of the cable strands, and the S
shaped nature of the bridge itself, the appearance or readability of such shows
may be limited or disrupted from many perspectives or vantage points and LDA
does not recommend this enhancement.
• This enhancement comes at a much higher cost to the project, adding over
$600,000 to the Intermediate Level.

Memo
Re: Scioto River Pedestrian Bridge - Contractor Selection Process and Construction
Phasing Update
Background
As a follow -up to the October 20 and December 5, 2016 updates provided to Council, the following
is a summary of the Scioto River Pedestrian Bridge project progress. The project is programmed in
the 2017 -2021 Capital Improvements Program with $22,750,000 budgeted for construction in
2017. The construction remains on schedule and within budget as final design progresses.
Delivery Method
Chapter 37 of the Dublin Codified Ordinances authorizes multiple forms of delivery methods for
infrastructure projects. The City traditionally uses the "design- bid - build" method to deliver public
infrastructure projects whereby the City either completes the design using its own design
professionals or retains a designer to furnish design services. The City then advertises and awards
a separate construction contract based on the completed construction documents. This method
provides for little builder input to the design. Thus, the owner relies on the designer for
constructability review. This approach is appropriate and works well for routine roadway work
where the work is relatively straight forward, the risks are easy to quantify and define, there are
minimal opportunities for innovation, the value of early contractor involvement would be minimal,
current comparable pricing information is readily available, and there is an abundant number of
qualified local contractors that could successfully build the project, etc.
However, due to the size and complexity of this unique, "s" curve, two span, suspension bridge,
with a tear drop shaped pylon, staff spent considerable time reviewing and considering the
alternative project delivery methods and procedural flexibility provided by Dublin City Code that
would help better ensure the best possible construction outcome. After discussions with the design
team, the City's legal counsel, and several other public entities throughout the country, staff has
concluded that the Construction Manager At Risk, also commonly called Construction
Manager /General Contractor, delivery method best met the needs and desired outcomes for this
project. The City is currently utilizing this delivery method to build the Justice Center addition and
renovation project, and both the City and the Columbus Metropolitan Library will be using this
approach for the new library area redevelopment projects. This delivery method provides for the
selection of a qualified contractor through a competitive process during the design stage. The City
contracts with the selected contractor to work closely with the City and design team to perform
preconstruction services such as constructability reviews, identify risks, provide cost projections,
and refine the project schedule. Then the contractor and project owner negotiate a Guaranteed
Maximum Price (GMP) for the construction contract(s). If all parties are in agreement with costs
and other terms, then the City contracts with the selected contractor for construction and
Memo re. Scioto River Pedestrian Bridge — Contractor Selection and Construction Phasing Update
January 5, 2017

construction begins.
Advantages of this delivery method include the following:
• Contractor selection based substantially on qualifications,
• contractor has input on the design documents due to being brought in during the design
phase, creating a collaborative design process between the contractor, designer, and City
staff, and producing higher design quality, and hopefully reducing costs,
• reduced risk and improved constructability,
• gain earlier and better knowledge and understanding of the project cost and schedule,
• flexibility to perform construction in phases through multiple packages, and
• flexibility to secure construction materials and equipment during the preconstruction phase
to reduce construction delays and avoid price escalations for volatile construction materials.
This construction procurement approach is being increasingly used as a preferred construction
delivery method for more complex public sector projects throughout the country, such as at The
Ohio State University, which has used this process extensively.
Due to the fact that under this alternative delivery method Council would not be awarding the
lowest and best bid as is typical of a "design- bid - build" approach, staff is providing this update
regarding the contractor selection process and anticipated construction phasing.
Contractor Selection Process
On November 30, 2016, four (4) Statements of Qualifications (SOQs) were received from
contractors for the bridge project. To determine which contractor is best qualified to successfully
execute the construction of the project the SOQ requested information related to each team's
project understanding and approach, organization, firm experience, and key personnel, capabilities
and experience, past experience and current performance. An Evaluation Team consisting of the
Director of Public Works, Director of Engineering /City Engineer, Infrastructure Asset Management
Engineer, Bridge Street District Program Manager, and Construction Engineer comparatively rated
and ranked the SOQs, short - listed two firms, and conducted interviews. Kokosing Construction
Company, Inc. (Kokosing) was selected based upon the established selection criteria. Kokosing is
extremely well qualified, has been in business since 1951, and is the largest construction
contractor in Ohio, and one of the largest in the Midwest. The company self - performs more than
eighty- percent of their work and is experienced constructing complex bridges including Columbus'
signature Main Street and Rich Street bridges, Fulton Road Bridge in Cleveland, and the I -71
Jeremiah Morrow Bridge over the Little Miami River valley in Oregonia, Ohio.
Kokosing started its preconstruction services work in mid - December and has surveyed the site,
reviewed the construction documents, participated in meetings with the design team, and is
providing the desired constructability, input that will enable the City and design team to further the
plan development and improve the plan quality. They are in the process of preparing formwork
shop drawings, identifying and working with potential suppliers, and obtaining pricing. Kokosing
will continue reviewing and providing input on the construction documents as they are finalized
and evaluating the project schedule and costs.
Construction Phasing
Memo re. Scioto River Pedestrian Bridge — Contractor Selection and Construction Phasing Update
January 5, 2017
Page 3 of 3
Staff anticipates bringing forward to Council a GMP contract with Kokosing for the initial phase of
construction as soon as the January 23, 2017 Council meeting. The initial construction phase will
include construction of the west abutment and plaza retaining wall. This portion of the project is
being closely coordinated with the adjacent Bridge Park West Building Z which is currently under
construction and proposed Building Z2, being considered for Basic Plan approval by City Council at
its January 10, 2017 meeting. Approval of the initial GMP contract will enable desired construction
sequencing in this area and allow work to progress on schedule, while facilitating other private and
public projects occurring within this area.
Additionally, Kokosing has identified the benefits of pre- ordering the structural steel as soon as
February due to the anticipated lead time, construction phasing needs, and to reduce the risk of
future price volatility. The advanced structural steel procurement is being considered as a second
GMP contract. Finally, staff anticipates bringing forward to Council a GMP contract for the third and
final phase of construction as early as March.
