ON THE WATER
MEMORANDUM
DATE: July 19, 2012
TO: Honorable Mayor and Members of the Common Council
FROM: Mark A. Rohloff, City Manager
RE: Amendment to Engineering Services Agreement—
Subsurface Exploration and Geotechnical Engineering Evaluation for the
City Hall Area Storm Water Detention Basin /AECOM Technical Services (AECOM)
In February 2012, a contract was awarded to AECOM to provide subsurface exploration and geotechnical
engineering services associated with the preparation of construction plans and specifications for the City
Hall Area Storm Water Detention Basin. During the course of performing those services, it was
determined that additional services were necessary in order to make design-related decisions relating to
the project. These additional services included:
• Additional exploration to determine the extent of soil contamination near the intersection of
Jackson Street and Algoma Boulevard.
• Additional soil borings to better quantify underground conditions.
• Additional ground water monitoring to determine long-term ground water impacts relating to the
construction of the project.
The amount of this contract amendment is $17,350. This will raise the contract amount to $74,350 (not-
to-exceed). Funding for these services is available in the Storm Water Utility budget.
Chapter 12 of the Municipal Code of the City of Oshkosh 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 12-16 of the Code, I am hereby submitting this
report regarding this engineering services agreement amendment.
Please contact me if you have any questions concerning this engineering services agreement
amendment.
