RE: Budget Estimate for Construction Materials Testing of
MacArthur Drive and Bethel School Road
Traffic Signal Installation Project
TR03-01 A and TR03-01 B
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 Bethel School Road Traffic Signal
Installation 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 Bethel School Road Traffic Signal Installation project as
required by the construction drawings and project specifications
Earthwork - Sidewalk Replacement/Repair
LE will provide a soils technician to collect on-site soil samples for proctor compaction
tests of different soil types to be used for the sidewalk replacemenUrepair subgrade
Soils technician will perform inspection of materials being placed and will utilize a
nuclear density gauge to perform in-place density and moisture content test.

LE proposes to perform drilled shaft confirmation for traffic light pole standards LE
soils technician will verify drilled shaft diameter and shaft total depth measurements
immediately after drilling operations are completed, prior to concrete placement.
Concrete Placement Inspection
LE will provide a full time concrete technician during concrete placements This includes
the concrete pavement and any other miscellaneous concrete placements. The project
superintendent will be notified of any discrepancies noted during visual observation
Concrete samples will be taken at appropriate intervals as determined by the project
specifications Concrete 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 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
