Re: 24" Crosstown Waterline - Coppell, TX
Proposed Field Change No. 2
8" Waterline in Grapevine Creek
Dear Mr. Watts:
Pursuant to a request by the City of Coppell Public Works
Department, please provide us with a proposal for abandonment of
the 8" waterline in Grapevine Creek and subsequent ties to the
24" Crosstown Waterline in this same area.
Attached is sheet 4 of 34 of the contract drawings showing the
approximate locations of the tie-ins. Please provide us a lump
sum total amount, with a detailed cost breakdown, for performing
the following:
At approximate station 14+50, provide 8" flanged outlet, 8"
flanged gate valve, 8" DR14, PVC pipe (or 8" ductile iron,
Class 51) with M.J. fittings to tie to existing 8" cast iron
pipe to the west. Include thrust restraints.
At approximate station 18+70 to 18+75, provide 8" flanged
outlet, 8" flanged gate valve, 8" DR14, PVC pipe (or 8"
ductile iron pipe, Class 51), with M.J. fittings to tie to
existing 8" cast iron pipe to the east. Include thrust
restraints.
Abandon, in place, existing 8" cast iron pipe between
approximate stations 14+50 to 18+70. Delete relocate/adjust
pay item 6.7.3 (B).
The existing 8" line can only be abandoned between approximate
station 14+75 and approximate station 17+30. These are the
locations of two in-line valves on the existing 8" main. To the
east and west of these two valves, the existing 8" line cannot be
out of service for any considerable length of time, since it is a
main feed for services on the north side of Southwestern
Boulevard.

RE: Abandonment of the 8" water line in Grapevine Creek /Change
Order on 24" Crosstown Water Line Project
Dear Mr. Favre:
Per our conversation yesterday, I want to inform you that I feel
that it is necessary to tie the 8" water line on Southwestern
into the new 24" oneach side of Grapevine Creek. This section
of 8" line is a maintenance problem for the Utilities Department
and it needs to be abandon. It will also be in conflict with
the installation of the 24" line.
You did explain your reasoning for not showing this on the plan,
which were pressure flucuations. I do not see a problem with
the increase in the pressure plan which would occur in this line
if connected to the 24". Therefore, I would like to request that
~ chan~e order item be written up for City Council to review for
their approval.
Also, I recommend that the 8" line be connected to the 24" with
concrete pipe manufactured fittings. To insure that this does
not delay the project, please make the necessary arrangements.
