RE: JP No. 88009; Fill in Tract 7;
Parks of Coppell; Coppell, Texas
Dear Jay:
I visited the site on December 27, 1989 to review the
construction status. This date is 30 days after the construction
start date of November 28, 1989.
The construction completion date according to the contract is
December 27, 1989. Requests for extensions have been submitted
by the contractor totalling 4.5 days for time lost due to
inclement weather. Copies of these time extension requests are
enclosed. Due, to severe cold weather in this area during recent
weeks, these requests are approved. In addition, an
unanticipated city holiday on December 26, 1989 prevented the
contractor from working on that day. Therefore, the contract
deadline is extended a total of 5.5 days to January 2, 1990.
From a visual review of the site on December 27, 1989, it
appeared that the work is nearing completion. Clearing in the
borrow area had been completed and cleared material had been
burned. Some excavation work remained in the eastern portions of
the borrow area. The contractor has requested that our surveyors
proceed with grade verification on January 2, 1990.
Topsoil taken from the borrow and fill areas is stockpiled near
the southeast corner of the fill area. This topsoil will be
respread in the fill area following placement of material
excavated from the borrow area.
The existing fence along the east side of Denton Tap Road was
used as the westerly limits of the fill. This fence is located a
short distance east of the east Right-of-Way of Denton Tap Road.
The contractor has made an effort to protect trees in the fill
area. These trees are located near the south limits of the fill.
Proposed grades were adjusted in the vicinity of the trees to
avoid damage to them.

Baker-Shiflett, Inc. has provided results of 56 compaction tests
taken on the fill through December 14, 1989. Results of three of
the tests showed compaction levels less than density required by
specifications. These areas were reworked and retests indicate
compaction levels in compliance with the specifications.
Due to lower elevations existing in the fill area at the start of
construction than elevations shown on the plans, and variations
between anticipated and actual shrinkage and loss factors, final
elevations in the fill area are anticipated to be somewhat lower
than the targeted elevations shown on the fill plan. The
contractor has been directed to bring the fill up uniformly in
order that constructed grades are in accordance with proposed
slopes and drainage patterns shown on the fill plan.
The east-west fence that was located south of City Hall has been
taken down. A portion of the fence near the northwest limits of
the borrow area has also been taken down. The contractor
indicated that the property tenant has removed most of the fence
materials from the site.
After checking the excavated grades in the borrow area, I will
notify the engineers for Parks of Coppell Joint Venture II that
obligations defined under Paragraph 2 of the Development
Agreement have been fulfilled. If you have any questions, please
call.
Sincerely,/~
Jerr~ Parche P.E.
