Re: Vfllage Parkway Pump Station
Gate Valves
Dear Mr. Pafford: t~ f t4~ 6 ~4 r
We have received your 4/10/89 memo along with a copy of the 1986 letter from
American Darling Valve Company. Our understanding from previous conversations
was that American Darling would supply stainless steel body bolts on all gate
valves furnished for use in the City of Coppell. Per the wording of the
letter, it appears American Darling's intention was to supply stainless steel
body bolts only when specifically requested.
The Contract Documents for this project contain no specific provisions
requiring the use of stainless steel body bolts on gate valves. The American
Darling valves submitted appear to comply with the applicable AWWA and
technical specifications for this project. Based on this information and your
direction, the American Darling valves were approved on 3/16/89 with a
notation reminding American Darling of the City's desire to have stainless
steel body bolts.
Since that time, American Darling through Cajun Contractors, Inc. has
requested an additional $2,168 to provide the requested bolts. We do not
believe the City has the contractual right to require submittal of a different
valve manufacturer at this time; therefore, if you still feel the stainless
bolts are justified, please submit a request for a change order.
We wish to note that we see no benefit from requiring stainless steel bolts on
valves with cast iron bodies. Dissimilar metal corrosion will utilize the
valve body as a sacrificial anode and gall the threads creating future
maintenance problems. The standard cadmium plated steel bolts will act as an
anode for the valve body, thus lengthening the valve life at less cost to the
City.
Please review this matter and provide us direction as soon as possible. We
have been advised by Cajun that these valves are scheduled for immediate
production. This issue must be resolved or shipment and construction
schedules will be impacted. Please contact us if you have any questions.
Sincer~y,
Sanf~6~d W. Case, P.E.

Attention: Mr. Sanford Case, P. E.
R: Village Pkwy Pump Station
Gentlemen:
Cajun Contractors, Inc. has reviewed your comments on the gate
valve submittal for the above referenced project and must make
the following comments.
Your comments required American Darling to use stainless steel
bolts on the valve body. Upon thorough review of the
specifications, Cajun can find no such requirement. Unless we
have overlooked this requirement in the Contract documents, this
work would be an extra to the Contract. Should the Owner choose
to have stainless steel bolts, Cajun proposes to provide them on
the buried gate valves for an additional cost of $2,168.00.
Your cooperation in clarifying this matter with the Owner and
responding to us at your earliest convenience shall be
appreciated. Should you have any questions, please do not
hesitate to call.
Sincerely,
CAJUN CONTRACTORS, INC.
