RE: JP No. 88023; Parkway Boulevard end High School
Access Road; Parks of Coppell; Coppell, Texas
Dear Buddy:
Enclosed is a copy of Payment Request No. 5 ("estimate") received
from L. H. Lacy for work performed on the referenced contract
from July 26, 1989 to August 5, 1989. This payment request was
received in our office on August 10, 1989.
Payment for all water, sanitary sewer and storm drainage
improvements under this contract was approved previously.
Payment for all paving improvement items except numbers 1, 9 and
11 vas approved previously. Following is a discussion of the
current status of these three items.
PAVING IMPROVEMENTS - ITEM NO. 1
In our review of the contractors' previous payment request
of July 25, 1989, we recommended withholding some payment
under this item since initial strength test results
indicated that the concrete strength of approximately 319
s.y. of pavement was not in compliance with project
requirements. At the direction of the City, samples were
taken of this pavement and tested. Test results were
received August 8, 1989 and indicate that the average
concrete compressive strength in this area is 3,746 p.s.i.
The City of Coppell has accepted this pavement.
Since all concrete placed in Parkway Boulevard and the High
School Access Road under this contract has been accepted by
the City, payment requested under Item No. 1 of the paving
improvements is approved.
PAVING IMPROVEMENTS - ITEM NO. 9
From a review of the site on August 24, 1989, no grass is
evident in the hydromulched areas. This was discussed with
Mr. Skip Klement of L. H. Lacy at that time. Mr. Klement
indicated that they would discuss this issue with their
subcontractor and direct him to take whatever measures are
necessary to establish a cover of grass in the seeded areas.

Final payment for work performed under this contract cannot
be recommended until all items are completed. Payment
requested under Item No. 9 of the paving improvements should
be withheld until there is a solid cover of grass in the
seeded areas.
PAVING IMPROVEMENTS - ITEM NO. 11
In our correspondence to you of August 1, 1989, we informed
you of the City's request for channellzation buttons on the
north side of Parkway Boulevard to direct westbound traffic
into the left turn lane at the High School Access Road until
Parkway Boulevard is extended further west in the future.
These buttons were installed and accepted by the City.
Payment for item number 11, Paving Improvements is approved
as requested.
The contractors' current payment request of $83,102.15 is for
full payment under this contract. The contractor indicates the
total of previous payments to be $174,168.91. Total recommended
payment prior to this request was $235,107.60. Therefore, of the
current payment request of $83,102.15, $60,938.69 had been
previously approved for payment.
The following table provides a determination of the current
amount now due.

the contractors' request ($174,168.91) is still accurate, current
payment now due is $65,745.88. If payments made to date equal

time constraint of 120 calendar days were completed by August 7,
1989, which was the contract due date. Bermuda grass in Medians
