RE: Creekview Drive and Freeport Parkway Project ST 00-01
Construction Materials Testing
Dear Mr. Stettner:
The City of Coppell intends to construct the Creekview Drive and Freeport Parkway
Project. The project consists of approximately 2800 linear feet of four-lane undivided
roadway, the reconstruction of approximately 800 linear feet of an existing two-lane
road to a four-lane divided roadway, drainage improvements, sidewalks, and 3600
linear feet of 8- to 12-inch water line. It is anticipated that construction will begin in
October 2001. 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. 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,
Suzar(C~ Taylor
