RE: Engineering Services Amendment for Design of the Snell Road Sanitary Sewer Pump Station / AECOM
Technical Services, Inc. (AECOM) ($97,687.25)
BACKGROUND
The City is planning on constructing the Snell Road West Lift Station, which will replace the existing Fountain Avenue
Lift Station. This construction is part of a multi-phase construction process over the next several years. Currently, the
sanitary sewer collection system to the east of the existing pump station is at capacity, hampering future development.
The overall construction will re-route some of the existing flows to the proposed lift station, which will give the sanitary
sewer additional capacity providing the City the potential for future development. In February 2014, AECOM was
chosen to provide these design services. In August 2014, the Common Council approved an amendment to this
agreement.
ANALYSIS
During the design process, it was determined that additional services would be needed to finish the design:
1. Abandonment of the existing Snell Road Lift Station in front of the Oshkosh Correctional Institution—This was
not included in the original request for proposals. Incorporating the abandonment of the lift station into the
construction bid will improve project efficiency and provide cost savings.
2. Combining the proposed Snell West Lift Station project and the Snell Sanitary Sewer Interceptor project into
one project in order to save costs by reducing duplication of efforts on bidding documents, permits, contractor
scheduling, and project management.
3. Installation of a permanent storm sewer to be used as the water discharge pipe required by the proposed high
capacity dewatering permit. This permit requires a temporary 18" diameter water discharge pipe to be
installed to the stream located several hundred feet west of the site at a cost of approximately $25,000 —
$45,000. This storm sewer will also provide long-term surface drainage improvements to the area.
4. Subcontracting for additional drilling for the installation of four or five 6" wells for the additional hydrologic
study and for use for dewatering during construction.
FISCAL IMPACT
The cost of these additional services is $97,687.25, which brings the total agreement amount to $328,103.25. Funds
for this project are included in the Wastewater section of the 2015 Capital Improvement Program (CIP).
RECOMMENDATIONS
Chapter 12 of the Municipal Code of the City of Oshkosh provides that professional services of a specialized nature,
including engineering services, may be procured without the use of formal, sealed quotes. I have reviewed the
proposal and in accordance with Section 12-16 of the Code, I am hereby recommending that the Common Council
approve this amendment.
Approved,
