MEMORANDUM
TO: Honorable Mayor and Members of the Co n Council
FROM: James Rabe, Director of Public Works
DATE: March 17, 2016
RE: Approve Amendment to Intergovernmental Agreement between Winnebago County, for
Wittman Regional Airport, and the City of Oshkosh for Installation, Maintenance, and
Operation of a Storm Sewer
BACKGROUND and ANALYSIS
The Common Council approved an Intergovernmental Agreement with Winnebago County for Wittman
Regional Airport at their October 13, 2015 meeting (Resolution No. 15-443). Since that time, the Contractor
working on the project, Vinton Construction Company, has encountered several changes in conditions from
the bidding documents that require a change order to their contract with the Wisconsin Department of
Transportation, Bureau of Aeronautics. These changes in conditions include an increased amount of rock
excavation required in order to install the City's storm sewer pipeline through Wittman Regional Airport, and
changes in design due to Canadian National Railroad changes to their requirements since issuing the City
of Oshkosh a permit to install storm sewer, water main, and sanitary sewer under their railroad spur line.
This amendment to the Intergovernmental Agreement will only update the total dollars paid portion of the
Payment Section of the Agreement. All other rights and responsibilities within the original agreement
remain in effect.
FISCAL IMPACT
The amendment increases the cost to the City's portion of the project by $373,542.39. Of that amount,
$29,400 will be charged to the Water Main section of the CIP, the remaining $344,142.39 will be charged
to the Storm Water section of the CIP.
Funding for this amendment is available in the Storm Sewer section of the CIP and in the Water Main
sections of the CIP due to other projects coming in under budget.
RECOMMENDATIONS
I recommend approval of the amendment to the intergovernmental agreement between Winnebago County,
for Wittman Regional Airport, and the City of Oshkosh.
Approved,
