Memo
Re: Resolution No. 54 -12 - Muirfield Drive Tunnel Improvements - Bid
Acceptance
Summary
On August 9, 2012, two (2) bids were received, publicly opened and read for the Muirfield Drive Tunnel
Improvements project, which involves retaining wall repairs and tunnel extensions of existing nine -foot
diameter concrete pipe pedestrian tunnels at two locations on Muirfield Drive. One tunnel is located
approximately 450 feet south of Whittingham Drive, while the other is located approximately 100 feet
south of Tarton Drive.
Each tunnel location consists of two tunnels with full- height retaining walls on each end. The retaining
walls, composed on masonry block and stone facing mortared in place, have deteriorated over the years
and need to be replaced. Considering bike lanes have been programmed for installation on the outside
of Muirfield Drive in 2014, the outside ends of each tunnel will be extended by approximately 16 feet to
provide sufficient roadway width for the bike lanes and required guardrail offsets. Once the existing
retaining walls have been removed and the tunnels extended, new concrete gravity retaining walls will
be constructed with synthetic stone facing. Additionally, the roadway pavement will be replaced where
removed for the work, new timber guardrail will be installed, and the embankment adjacent to the
tunnels will be restored with new turf (grass seed, fertilizer and straw).
The Engineer's estimate is $670,000. The funds for construction of this project are from the Capital
Improvements Tax Fund. Trucco Construction Company, Inc. submitted the lowest and best bid of
$864,069.50. Staff has reviewed all bids and a summary of the bids is listed below.
For Council's reference and review, a reduced set of project construction drawings has been placed in
the Council Planning Room.
Staff has compared the Engineer's estimate to the two bids received. Several factors likely generated
higher costs than estimated. First, the project is not a routine tunnel repair and retaining wall project,
thereby making it difficult to accurately estimate certain costs. The project has several components -
there are four sloped concrete retaining walls to construct at two separate tunnel locations for a total of
eight retaining walls. The two tunnel locations are over 4,000 feet apart (about 0.8 miles) requiring

individual equipment mobilization, maintenance of traffic and logistics. Second, several of the units
prices bid were higher than those estimated, for example, instance the 610 cubic yards of Class C
concrete to be placed for the retaining walls at $525.00 per cubic yard (for a total of $320,250).
Another likely factor impacting the bids is the performance of the project in the fall construction season,
at a time when many contractors and subcontractors have already committed to other projects.
In late February of 2011, a portion of the existing retaining wall on the east end of the tunnel located
south of Whittingham Drive collapsed after a heavy rain storm. At the direction of Dublin staff, Strawser
Paving Company (Strawser) removed the retaining wall, extended the tunnel 24 feet with the installatior
of nine -foot diameter concrete pipe, widened the roadway, installed new timber guardrail and restored
the turf. The cost of this work was approximately $65,000, which did not include the replacement on
the retaining wall. The unit cost bid by Trucco Construction Company, Inc. (Trucco) for constructing a
retaining wall with synthetic stone facing at each of the eight locations is $57,000 for the smallest wall
location (all eight walls to be replaced vary in height and width). Using the combination of the past cost
incurred by Strawser and the retaining wall cost bid by Trucco, these improvements of the eight tunnel
ends would total more than $975,000.
Staff anticipates the construction to commence before the end of September. Muirileld Drive will
remain open to traffic for the duration of the construction, although temporary closure of one lane will
likely be necessary during various stages of the work. Staff will carefully coordinate these closures to
minimize interruptions to motorists. The scheduled completion for this project is mid - November of this
year, dependent upon weather. It is possible that a portion of the work may not be completed until the
spring of next year. However, all work will be completed prior to the 2013 Memorial Tournament.
Recommendation
Staff has thoroughly reviewed the Trucco bid, and although higher than the Engineer's estimate, finds it
to be a true and accurate cost to perform this tunnel improvement project. Previous experience with
Trucco on several projects over the past ten years has been favorable, including the completion of the
UNI- 161 -12.98 Industrial Parkway Project in 2009 -2010.
Staff recommends Council approval of Resolution 54 -12, accepting as lowest and best the bid of Trucco
in the amount of $864,069.50 and authorizing the City Manager to enter into a contract with Trucco for
this project.
