Construction Materials Testing
Dear Mr. Gray:
The City of Coppell intends to construct the Ruby Road project. The project consists of
the reconstruction of 2700 linear feet of an existing two-lane asphalt road to a two-lane
undivided concrete roadway, 2220 linear feet of storm drain, 2900 linear feet of water line,
and 750 linear feet of sanitary sewer pipe. It is anticipated that construction will begin in
December 2002. We are providing an estimate of the type and number of construction
materials tests required for the project based on the construction plans and the City's
standards. The contractor is responsible for payment of materials testing done before
8:00 a.m. and alter 5:00 p.m Please submit a proposal for the construction materials
testing.
Your consideration of this matter is appreciated and should you have any questions or
need any additional information, please contact me at 972-304-3679.
Sincerely,
