Re: WesYe~r~Y Interceptor and Reclaimed Water Transmission Main,
CPH lob No. S0602.68 and S0602.69
Dear Mr. Moore:
The work on the subject projects is nearing completion and we anticipate preparing the final
certification for the project as soon as we receive the as-built drawings prepared by S&E
Contractors, Inc.
A review of the costs incurred to date for bidding services and services during construction,
indicates we have exceeded the originally authorized fee. We feel a number of conditions which
were beyond the scope of the original Contract contributed to the additional costs. We have
identified these conditions below:
Design of stormwater drainage improvements on ~ Lane
Evaluations, project meetings and correspondence with regulatory agencies in connection
with the slopes for the gravity sewer lines
Investigations and correspondence regarding material damage on the 30" gravity sewer,
and negotiation of an extended warranty for the 30" pipe material supplied by Carlon.
As you know this material was bid as a deductive alternate and based on a $50,000
deduct, was accepted for use. During construction, a section of pipe was damaged which
raised concerns regarding the acceptability of the pipe. We investigated the failure and
prepared more stringent testing requirements. We have negotiated to obtain a three year
extended warranty for the pipe due to the concems.
Evaluation of an alternate lining material for the 5th Street lift station wetwell including
negotiations for an extended warranty on the product.

In addition, all work on the project including punch list items was to be completed by November
12, 1992 based on the original project schedule. We are continuing to work on the project as
of this date. The as-built drawings were not received until the week of December 14, 1992 and
we are currenfiy working on resolving several items in the as-builts in order for us to prepare
the project certification.
We attempted to complete all of the work within the originally authorized fee. As of December
2, 1992, we exceeded the original fee by $3,483. Some additional effort will be required to
complete the project primarily involving preparation of the final change order including
submissions to FDER Tallahassee, and final certification of the project to FDER.
We respectfully request that you authorize an increase in the maximum fee for the subject
projects of $5,500, for a revised total maximum fee of $59,850.47.
If this letter request meets with your approval, please so indicate by signing and returning one
copy for our files.
Thank you.

RE: Amendment No. 32 - Engineering Services for Construction
of Westerly Interceptor and Reclaimed Water Transmission
Mains (Contracts I & II)
Dear Cal:
Enclosed herewith, please find one (1) fully executed copy of
Amendment No. 32. We would like to proceed with advertising and
bidding of Contracts I and II as soon as possible, in order to have
actual bid prices prior to the planned sell of Utility Bonds in
early August. I realize that redesign of a small segment of the
reclaimed water line will some what delay advertisement, but hope
we will be able to obtain amended FDOT right-of-way use permits in
the near future, in order to complete the FDER required site
certification.
