Dear Ms. Johnson:
Enclosed are three copies each of the Pay Estimate No. 8, Change..Order No. 1, and
ava ENcw€:RINC: Certificate of Substantial Completion for -the above referenced project. Included in the. pay
ENviRONMENTAi estimate is the $4,241 deduct from Change Order No. 1.
M'JNKIPAI
~L4NNMIG .Change Order No. 1 includes all the miscellaneous changes during the course Of the interim
s~IDw,asT~ improvement project. These .changes were made to facilitate the next phase. of plant
sTRUCruRai expansion and to minimize the construction cost.
SURVEYING
TRAP~ic The Contractor, Gridor Construction, .Inc. had completed the project substantially, prior
TnANSPORTATION t0 November 30, 1994, the contract date for substantial completion. The facility haS been
in satisfactory operation since then, and has brought the Plant back in compliance .with the
~CTRICAI/MECHANICAL perITllt. There are Iftlllor items t0 be finished by the Contractor, aS shown in the punch list
:NGlNEERI"~: attached t0 the Certificate. of Substantial Completion. The Contractor agreed to finish these
^~A` items by Febniary 28, 1995, except the items that need to be done in the S nn These
°OwER DISTRIBUTION p g'
items should not affect the operation of the facility.
SCwDA
sYSTEMcoNTRO`s The revised contract price, after the $4,241 .deduct from. the Change Order No. 1 is
$914,259, less the $892,500 previouslypaid, the amount due the Contractor is $21,759.
We recommend the Council to approve the Change Order, Certificate of Substantial
Completion.., .and the payment.. We also .recommend, the City continue to withhold the
retainage until the items in the Bunch list are complete.
' Finally, we like to recognize Mr. Darrell Mack for his foreseeing .suggestion in the
Summer of 1993 to implement this interim improvement, when -one of the rotating
biological .contactors. failed. By the time the Minnesota Pollution Control Agency issued
GFFICES IN:
a violation letter, we were already one step. ahead of the Agency, and had finished the
Nr~EAPOUS design of the interim improvements. During the Summer of 1994,. the plant experienced
P~Ioa ~,KE a very difficult operation. striving to stop further degradation of effluent quality. Now, the

Plant is back in compliance, the MPCA is pleased about the City's prompt remedial action,
and the City has avoided an enforcement action or a penalty from regulatory agencies,
which could have cost the taxpayers thousands of dollars and halted community growth,
Thank you very much for your assistance in our construction administration. If you have
any questions, please feel free to call me at 644-4389.
Sincerely,
