Re: Sandy Lake Road Project # ST 93-02
Dear Mr. Weber:
This letter is written in response to your March 23, 1999 letter concerning price adjustments for
lowering 8", 10" & 12" water lines in conflict with the proposed construction along Sandy Lake
Road. During our telephone conversation of March 24, 1999, I indicated that upon my review of
the plans and specificadons it was my determination that the lowering of 8" water lines should be
handled under Pay Item #89 and the lowering of 12" water lines should be handled under Pay
Item #88. If we do encounter any 10" water lines we would pay for them at the same price as the
12" water line, which is $48/per linear foot. Your letter makes the point that it was anticipated
that all the lowerings would be approximately 45-feet in length. However, the plans show only 3
lowerings of the 12" water line: 1) Sta. 68+15 - 10 feet, 2) Sta. 56+20 - 16 feet, 3) Sra. 55+08
10 feet. All those lowerings have fittings associated with them plus blocking, etc. The
description of Pay Item #88 and #89 specifically states that the price per foot includes all fittings,
restraining joints, blocking, dewatering, excavation, backfilling, disposal of existing materials,
etc.
It should be anticipated on a project of this magnitude and length that there will be conflicts with
existing utilities during the course of construction. It is very difficult to ascertain the exact
elevation of underground utilities during the design of a project. If you were unclear on how you
would be compensated for conflicts with exisdng utilities encountered during the course of
construction, that should have been brought to the attention of the City prior to submitting a bid
on the project. Section 6 of the bidding document states that it is the bidders responsibility to
carefully examine the contract documents, study and carefully correlate observations with the
contract documents and notify the engineer of any conflicts, errors or discrepancies in the
contract documents. It has always been the design engineer's understanding and the City's
understanding that the aforementioned Bid Items #88 and #89 were meant to cover any conflicts
encountered during the construction of the project.
Your request for additional compensation per foot for the 8" water lines encountered at Fountain
View and Meadowglen, the 10" water line encountered at Mapleleaf, the 12" water line
encountered at Heartz and any other water lines that may be encountered during the course of
construction is not approved. Again, all water line adjustments associated with those conflicts
will be paid under Bid Items #88 and #89. The City is requesting that work on the project
continue without delay and that any water lines encountered be lowered and put back in service
with payment under Bid Item #88 or #89.
If you should have any questions please feel free to contact this office at your convenience.
Sincerely,
Director of Engineering/Public Works

Dear Mr. Griffin:
As you are aware, there has_been a great deal of discussion regarding .u. tihZation of item #89, 8"
CL 250 DI Water Line~ to pay for., the two water line adjustments that have been identified to'
date, The water line adjustments;i identified in. the plan, s..i that comprise thg-quantity for item #89
average 45 feet in lengthw~th tW°fittings: The-additi0~~ water li~e .ad,'~julstments that hav~ ~en
identified:to date ar6'appr0ximate!y 20"feet in Iehgt~n~ require fiYe-fi_tfiags. The additional,
fittings reqUired and' the additi0n~/1 labOr and'equlpment .CoSts requi~ed't°' install those fittings
spread over a shorter length of water line make the unit.price much higher than the bid price for
item #89. It is our belief that the character of the additional work is Significantly different 'than
the work represented by item #89; therefore, we request that an item for lowering an 8" water
line be established.
The following comparison between the price for item #89 and the price for a shorter 8" water line
lowering illustrates the differences in the price for the two types of water line lowerings:
8" DI Water Line (as bid) 8" DI adjustment
(averaged over 45 LF) (averaged over 20 LF)
8" DI water line $8.47 $8.47
Embedment '$1.11 $1.11

Re: Water Line Lowerings
Based upon a unit price of$111.00 per LF, the lump sum price for a 20 LF water line
lowering/adjustment would be $2,220.00. For reasons of clarity, we would prefer to be paid for
this work utilizing a lump sum pay item.
It is our understanding that a similar adjustment is necessary for an existing 12" water line and
may become necessary for a 10" water line. Additionally, it is apparent that multiple
adjustments will be required and that pre-approved prices for this type of work will minimize
delays to the project. Based upon a similar analysis, our prices for 10" and 12" water line
adjustments are as follows:
10" water line adjustment
$2,465.00 per location
12" water line adjustment
$2,630.00 per location
Please add an additional two calendar days to the project's duration for each water line lowering.
If you have any questions regarding this issue, don't hesitate to contact our office.
