TO: Honorable Mayor and Members of the Common Council
FROM: Mark A Rohloff, City Manager ��,� ---
RE: Amendment to Agreement for Engineering Services for Various Wastewater Treatment
Plant and pumping station improvement projects/Strand Associates (Strand)
In May of 2011, an engineering services agreement was awarded to Strand for the design, bidding, and
construction services for improvements to the Wastewater Treatment Plant and Sawyer Creek Pumping
Station, as identified in the 2011 Capital Improvement Program. Pumping station improvements included
replacement of the electrical control panel and the addition of a back-up generator. Treatment plant work
included replacement of the central gate between aerated grit chambers, installation of isolation gates on
four primary clarifier effluent channels, repair of miscellaneous above-grade primary clarifier concrete,
and replacement of submerged inlet baffles on the secondary clarifiers.
Additional services were required during the design phase to prepare an application and documentation
for a hearing by the Board of Appeals for project approval. Additional services were also required during
the bidding phase because the original bid came in over project estimates and the decision was made to
rebid the project. The results of rebidding this project resulted in a savings of$217,200.
The original agreement was in the amount of$130,000. The amendment is for$44,000, which brings the
total for engineering services expense to $174,000. This project is funded through the Capital
Improvements Program (Wastewater Utility Fund). Funding for these services is available in this account.
Section 12-10(D)(5) of the Municipal Code provides that professional services of a specialized nature,
including engineering services, may be approved by the City Manager without the use of formal sealed
quotes. In accordance with Section 12-10(E) of the Code, I am hereby submitting this report regarding
this engineering services contract.
Please advise me if you have any questions concerning this engineering service agreement.
