RE: Amendment to Engineering Services Agreement to Conduct a Sediment Sampling Investigation
and Sediment Disposal Characterization for the Sawyer Creek Channel Creek Improvement
Project/AECOM ($9,584.18)
BACKGROUND
Advance Construction, Inc. was awarded Contract 12-03 — Sawyer Creek Channel Improvements at the May 22,
2012 Common Council meeting. While dredging in the area between Sawyer Street and the Fox River, a sheen
appeared on the water surface. The appearance of the sheen is an indication of contaminated sediment. The
Department of Public Works contracted with AECOM to determine the nature and extent of the contamination and
to provide recommendations for the approach for the remainder of the dredging and for disposition of the dredged
sediments. Their recommendations were submitted in a report dated February 14, 2013.
The report recommended collecting additional sediment samples and providing a summary report. The
Wisconsin Department of Natural Resources (WDNR) also added additional requirements. The services needed
to meet these requirements included sampling of the discharge water from the dewatering area prior to entering
the Fox River or the City of Oshkosh sanitary sewer system; completion of Discharge Monitoring Reports for the
WDNR; and coordination with the WDNR, the City of Oshkosh, and the dredging contractor.
AECOM submitted an amendment to the engineering services agreement to complete these additional services.
ANALYSIS
AECOM was chosen due to their experience on previous environmental engineering projects for the City. Staff
has reviewed the amendment and costs. The proposed fee is time and materials $9,584.18 for a total contract
amount of$136,349.18.
FISCAL IMPACT
Funding for these services is available in the Storm Water Utility.
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 this amendment and in accordance with Section 12-16 of the Code, I am hereby recommending that the
Common Council approve this amendment.
Approved,
