Request For Proposal
Dear Mr. Walton:
The City of Coppell intends to reconstruct 4234 linear feet of Sandy Lake Road, from Kimbel Kourt to
thc cast city limits. ~hc existing tx~o-lanc asphalt roadway x~ill be replaced with a four-lane divided,
concrete roadway with improved storm drainage. Thc elevation of the road will be raised an average of
four feet to remove the proposed roadway out of the floodplain. Construction of the project will be
phased and temporat3' special shoring and HMAC detours installed to allow for two-way traffic during
the duration of construction. The project also includes thc installation of 652 linear feet of 10' x 8' box
culvert and 10,116 square yards of concrete block retaining wall. Thc project bid opening is November
16, 2004 and construction is anticipated to start in the 1st quarter of 2005.
We are requesting your firm, along with two othcr firms, to submit a proposal for thc construction
materials testing on the Sandv Lake road project An estimate of thc type and number of construction
materials tests requircd for thc project is enclosed for your use in preparing the proposal. Please submit
the proposal within the next three weeks The city will select one firm for the materials testing based on
the proposals. Do not submit a materials testing cost for the projcct with the proposal.
