RE: Budget Estimate for Construction Materials Testing of
MacArthur Blvd. and Cribbs Drive
Drainage Project
DR 06 -01
City of Coppell, Texas
Dear Ms. Taylor,
Lawrence Engineering (LE) is pleased to be selected for the construction materials testing
services for the MacArthur Drive and Cribbs Drive Drainage Project at Coppell, Texas. Our
scope of services is based on our understanding of the project plans and project specifications.
In addition to specific information provided, LE has comprised this project fee schedule based
on an estimated duration of the construction period and typical construction methodology.
Therefore, we request that you carefully review the on -site duration and frequency of testing to
compare with your estimated construction schedule. As you know, our cost is directly
dependent upon the time duration and construction methodology utilized.
Scope of Services
LE proposes to provide the following Construction Materials Testing Services for the MacArthur
Drive and Cribbs Drive Drainage Project as required by the construction drawings and
project specifications.
Concrete and Flowable Fill Placement Inspection
LE will provide a full time concrete technician during concrete and flowable fill placements. This
includes the concrete pavement and any other flowable fill placements. The project
superintendent will be notified of any discrepancies noted during visual observation. Concrete
and flowable fill samples will be taken at appropriate intervals as determined by the project
specifications. Concrete and flowable fill samples will be tested for temperature, entrained air
content, slump, and compressive strength.

Cost Estimate
Presented on Table I attached is our cost estimate for this project. LE's estimates of testing
quantities are based upon material estimates obtained from the Project Construction Drawings
and assumed accepted industry standards for items not specified. We believe that our total cost
estimate is realistic for this project; however, this estimate may be increased or decreased
depending upon the actual project progress and the conditions encountered during project
construction. These are estimates. Consequently, billings only for services rendered will be
based primarily upon the unit rates presented in Table I.
An invoice for services performed during each month will be sent within the first 10 days of the
following month. Payment for our services will be due within 30 days of receipt of invoice.
Schedule
Lawrence Engineering is prepared to begin work immediately upon notification to proceed from
the project representative. We are prepared to respond to your needs with due diligence in a
timely fashion, as well as establish a level of communication which facilitates progress.
Acceptance
Lawrence Engineering is committed to, and capable of, providing the required materials
engineering and testing services that are necessary for timely and professional project
performance. LE's engineering technicians are either certified by the American Concrete
Institute and National Institute for Certification in Engineering Technologies (NICET) or enrolled
in certification programs. Lawrence Engineering is regularly inspected by the Cement and
Concrete Reference laboratory (CCRL), is accredited by American Association of State
Highway and Transportation Official (AASTHO), and is certified by North Central Texas Region
Certification Agency as Disadvantage Business Enterprise (DBE).
We thank you for your consideration of this proposal and look forward to serving your
professional needs on this project. If you require further information, please do not hesitate to
