Item 4ECITY OF
SOUTH LAKE
MEMORANDUM
(April 21, 2009)
To: Shana Yelverton, City Manager
From: Robert H. Price, P.E., Director of Public Works
Subject: Award of construction contract for the Dove Road Intersection
and Drainage Improvements to Quality Excavation, Ltd. in the
amount of $2,983,435.26 and authorize construction phase
contingencies
Action
Requested: Award of construction contract for the Dove Road Intersection and
Drainage Improvements to Quality Excavation, Ltd. in the amount
of $2,983,435.26 and authorize construction phase contingencies.
Background
Information: The intersection improvements will consist of the construction of
roundabouts at Dove Road and North Carroll Avenue and at Dove
Road at North White Chapel Boulevard to improve traffic flow within
the area. The project includes the relocation and /or upsizing of
existing utilities, drainage improvements and the construction of
sidewalks within the project boundary.
Construction will begin at the intersection of Dove Road and North
Carroll Avenue to take advantage of the CISD school summer
recess. The intersection of Dove Road and North Carroll Avenue
will be closed to traffic during the CISD summer break, beginning
on June 8, 2009. Closure of the intersection will allow the
contractor to complete the installation of the water line and the
storm drain pipe at the intersection along with earthwork and
paving. The intersection will be reopened to traffic by August 15,
2009, at the latest, and will function as a temporary roundabout
until the permanent curb and gutter is installed to complete the
project.
To ensure that the contractor focuses his efforts on completing the
work in the Dove and Carroll intersection so that the intersection
may be reopened as soon as possible, the staff and the consultant
developed a performance incentive specification for an expedited
opening of the intersection. The contractor will receive the full
performance incentive should he have the intersection substantially
completed and reopened to traffic in a six week period. For every
additional week that the intersection remains closed beyond July
19, the performance incentive will be reduced in accordance with a
sliding scale detailed in the contract documents. Should the
contractor fail to have the intersection substantially completed and
reopened to traffic by August 16, the contractor forfeits the entire
performance incentive.
After the Dove Road and Carroll Avenue intersection has reached
substantial completion, the contractor will be allowed to begin work
on the Dove Road and White Chapel Boulevard intersection. This
intersection will be partially closed during construction with
temporary pavement added on the northeast corner for detour
traffic. The contractor will not be allowed to work on both
intersections at the same time if the work requires closure of the
intersections simultaneously.
The drainage portion of the project consists of the construction of
an 8'x5' box culvert along the south side of Dove Road from the
intersection at North Carroll Avenue to Dove Creek, east of
Lonesome Dove Avenue. The project also includes the
reconstruction of Dove Road from North Carroll Avenue to
Lonesome Dove Avenue. Construction of this portion of the project
will require the closure of Dove Road to traffic during the day, with
the exception of local traffic, mail delivery and trash collection. The
contractor will reopen Dove Road to two -way traffic each evening.
Both roundabouts will incorporate design concepts from the City's
Urban Design Study which was approved by the Planning & Zoning
Commission and the City Council in 2008. A separate landscape
project will be awarded by the Community Services Department at
the completion of the Public Works construction project.
Four (4) bids were received on April 7, 2009. The bids were
reviewed by the design engineer, Teague Nall and Perkins. It was
determined that Quality Excavation, Ltd. had inadvertently included
a pay item which was deleted with the Addendum, and had noted
incorrect quantities on two other pay items. AUI Contractors, Inc.
had also noted incorrect quantities on a pay item. These
corrections adjusted the results of the original bid tabulation. The
original bid amounts and the adjusted bid amounts are as follows:
BIDDER
ORIGINAL
BID AMOUNT
REVISED
BID AMOUNT
Quality Excavation, Ltd. $3,014,484.56 $2,983,435.26
Tri Dal Utilities, Ltd. $3,068,878.70 $3,068,878.70
RKM Utility Services $3,114,734.30 $3,114,734.30
AUI Contractors $3,760,360.51 $3,773,410.51
Teague Nall and Perkins recommends award of the contract to the
low bidder, Quality Excavation, Ltd. City staff concurs with this
recommendation.
Financial
Considerations: The recommended contract award amount is $2,983,435.26. Staff
also recommends that the City Council approve an approximate
10% construction phase contingency of $296,564.74 in addition to
the award of $2,983,435.26 for a total project budget of
$3,280,000.00.

and the installation of the box culverts along East Dove Road from
