Re:
Denton Tap Road Improvements from Belt Line Road to Sandy
Lake Road from Sandy Lake Road to Denton Creek, Coppell,
Texas.
Dear Mr. Snyder:
The purpose of this letter is to update the status of Field
Extras for the project. For this purpose we are attaching a
Project Field Change Summary which lists each Field Change, its
cost, pertinent drawings, and general status of the item.
For the record we would like to address the following items:
FIELD CHANGE 2
This item consisted of replacement of 73.66 Lf of the
existing 12" VCP sanitary sewer (crossing the project
centerline at approximately station 114+38) with 12" DIP.
The replacement of the existing pipe was necessary due to
the poor condition of the pipe. We have requested a
breakdown of the $ 6,240.00 L.S. price quoted in the July
13, 1988 letter from L. H. Lacy Co., copy attached. To date
we have received no response.
FIELD CHANGE 4
This item has been established to eliminate any splices in
existing water services which would be located under the
proposed pavement. We have no objection to L. H. Lacy Co.'s
proposal for this item which is contained in the July 13,
1988 letter, copy attached.
FIELD CHANGE 5
This item consists of the installation of an 8" valve in the
existing 8" water line, at paving station 97+30, in order to
eliminate night lowereings of the existing 8" water line at
several storm sewer laterals. Because of the fact that the
subsequent water line lowerings were accomplished during the
day the City benefits from a better quality of installation
and the elimination of several line shutdowns requiring
attention of City personnel. L. H. Lacy Co.'s August 9,
1988 proposal for this work, copy attached, is acceptable.
17103 Preston Road · Suite 100 · i.I1 118 · Dallas. Texas 75248 · Phone 214/248-4900
FIELD CHANGE 6
This item was generated by our field representative's
observation that one of the proposed pipe supports for the
proposed extension of the existing 12" Sanitary Sewer Aerial
Crossing might be eliminated by repositioning the other five
proposed pipe supports. To date we have not received a
response to our letter of 8-18-88 requesting a proposal from
L.H. Lacy Co. for a reduction in the L.S. bid price for Pay
Item 582.14.
FIELD CHANGE 7
This item originated with L. H. Lacy Co.'s discovery that
the existing 8" water line was not located where indicated
on the plans, but instead was in conflict with storm sewer
line "B". We rejected L. H. Lacy Co.'s original proposal in
this matter, due to technical reasons, and we have not
received a new proposal at this time.
FIELD CHANGE 8
In order to facilitate a slightly different construction
sequence than that originally suggested in the bidding
documents, L. H. Lacy proposed an alternative plan for the
use of portable concrete traffic barriers and barrel guard
rail in the letter of August 16, 1988, copy attached. We
have no objection to this proposal.
FIELD CHANGE 9
This field change consists of the addition of a 6" valve in
an existing water line in a location where "as built" plans
indicated one would be located for isolation and repairs.
Installation of the valve as proposed is necessary for the
proper installation of the improvements proposed under the
Contract. This item is addressed in the August 29, 1988
letter, copy attached. We have no objections to this item
as proposed.
FIELD CHANGE 10
This item was proposed in the letter of September 2, 1988,
copy attached. It provides for the installation of a 2"
water service tap on the existing 16" water line located on
the east side of Denton Tap Road. This proposed 2" service
replaces a poorly installed existing water service which is
composed of four 1" services which are combined into a
manifold at the service end. We have no objection to this
item as proposed.
We trust that the above accurately reflects the state of Field
Extras associated with this project. We ask that you respond
promptly to those items identified above as needing a response.
If you have any questions pertaining to the above, please call
me.
Sincerely,
John C. Karlsruher, P.E.
Project Engineer
