Re: Denton Tap Road Improvements from Sandy Lake Road to Denton
Creek - Dallas Water Utilities' 30 Inch Water Line Lowering
Dear Mr. Snyder:
As a follow-up to your letter of January 20, 1989, regarding this
issue, I contacted Mr. Jim Rogers of Dallas Water Utilities this
morning. Mr. Rogers informed me that the design of the lowering
is complete with drafting to be completed today. Upon completion
of drafting Dallas Water Utilities will issue the drawings to
Gifford-Hill for fabrication of the necessary pipe and fittings.
DWU will not be able to schedule their City Forces crews to
construct the lowering until they are able to determine the
fabrication and delivery date of the necessary pipe, fittings and
materials.
Mr. Rogers did mention that he anticipated lowering about 200
feet of the water line to resolve the conflict. This information
may be helpful to you in planning your construction activities in
the area until we have a definite schedule from Dallas Water
Utilities.
It is the Contractual obligation of L. H. Lacy Co. that the
actual horizontal and vertical locations of all underground
utilities be verified prior to the beginning of construction, and
all discrepancies and conflicts be immediately brought to the
attention of the Engineer for resolution. Since most of the
utility work for this project was completed prior to verification
of the location of the 30 inch water line, we do not believe that
L. H. Lacy Co. has any basis for a claim for a delay as a result
of the subject conflict. Accordingly, you should plan your
sequence of construction to accommodate this situation.
Please call me if you have any questions.
Sinc~erely, ~
Project Engineer

Denton Tap Road Improvements From Sandy Lake

Project 379
City of Dallas 30" Water Line
Dear John:
While attempting to install lateral D-22 on Monday, November
28, 1988, our subcontractor, American Developers, uncovered
the 30" City of Dallas Water Line. It's at offset 167+32
and on the plans shows to be approximately at 44' right
of centerline. We have a field shot that shows it to be
at 42.7' right of centerline. The horizontal location is
not a problem; however, the vertical location of the 30"
water line on the plans shows to be at an elevation of 488.5
at 44' right of centerline. The actual field ties show
the 30" water line to be at an elevation of 492.21 at 42.7'
right of centerline. This interferes directly with the
lateral pipe and there would only be three or four .tenths
clearance below the bottom of paving at this station.
With the existing drainage structures and existing
intersection at Sandy Lake, there may be no recourse other
than that the City of Dallas lower their 30" water line.
Per our most recent schedule, we show Phase II excavation
to start in the third week of January, 1989 and we show
Phase II subgrade preparation to start in the second week
of February, 1989. We have some time to solve the problem,
but that window will close rapidly. It is L. H. Lacy's
intention to pave Phase II on the North Project before we
pave Phase II on the South Project. As we have stated before,
it is our intention to finish the North Project as soon
as possible. This will allow us to concentrate our efforts
on the completion of the South Project.

We know from previous conversations with the City of Dallas_.
Water Department that it would take two (2) to three (3)
'days to drain the 30" line once the valve had-been shut-off-.
Any solution(s) that will avert the relocation of the 30"
water line appear to be well warranted.
L. H. Lacy Company will have American Developers locate
the 30" water line for f~eld ties at laterals D-14 and D-16
as soon as possible. When this information is available,
copies will be forwarded to you.
