MEMORANDUM
TO:
Mayor and City Council
FROM: Kenneth M. Griffin, P.E., Director of Engineering/Public Works
DATE: April 26, 2005
Consider approval of awarding Bid/Contract #Q-03-05-01 to Whitewater
Construction, Inc. for the construction of the Oakcrest Drainage project in an
amount of $84,407.00, as provided for in Drainage CIP funds; and authorizing
the City Manager to sign.
On April 5, 2005 the City of Coppell received and opened one bid for thc construction of the
Oakcrest Drainage Project. This project is located along Oakcrest Lane, which runs south from
Bethel School Road approximately 1,400 feet east of Denton Tap Road. See the attached exhibit
for additional information on the location of the project.
The drainage along Oakcrest Lane consists of borrow ditches along the side of the street. The
lots that front the street, as well as the street, drains to the ditches, and the flow runs south to the
intersection of Meadow Creek Road. As the stormwater flows south, it crosses all the lots, and
crosses either under the driveways in culverts, or over the drives through a "valley gutter"
constructed in the driveway.
Most of the driveways and culverts were placed during the home construction in the late 1970's.
There appears to have been very little coordination between builders in the placement of these
drives and culverts. There is no consistent slope, and as such some of the water stands in places
along the ditch.
This project consists of grading of the borrow ditches along both sides of the road, and replacing
the culverts and drives in the areas that prevent the water from flowing to the south end of the
street.

The low bidder on the project was Whitewater Construction, Inc. of Waco, Texas, with a bid
amount of $84,407. This contractor has provided the City of Coppell references for prior
projects, and in speaking with them they have not offered any negative comments.
Prior to advertising this project for bids, city staff contacted Dallas County to request a cost
estimate for the county to perform this work. Since this is a residential street, the county would
perform the work, but the entire cost would be paid by the city. The county submitted a cost
estimate of $28,311.88. This estimate was for the removal of drives, ditch excavation,
installation of new culverts, and reconstruction of drives and the intersection of Sandy Oak.
Dallas County proposed repouring all the concrete removal with asphalt. Dallas County did not
provide a cost, and did not intend to perform the irrigation repair, the re-sodding of the ditch line
and the tree replacement.
After receiving the estimate from Dallas County, we decided to proceed with bidding the project
due to the amount of work that would need to be done after the county was done with the work
they were able to perform.
The Engineering Department designed this project in-house, and our estimate of cost was
$52,915 for the construction. The single bid submitted was in the amount of $84,407. Although
this bid is higher than we estimated, it appears to be a valid bid with reasonable and balanced
costs.
Staff recommends award of the contract for the construction of the Oakcrest Drainage Project to
Whitewater Construction, Inc. in an amount of $84,407, with an estimated completion time of 40
calendar days.
Staffwill be available to answer any questions at the Council meeting.
