RE: Amendment to Engineering Services Agreement for Libbey-Nicolet North Main Street Area
Detention Basin / AECOM Technical Services, Inc. (AECOM) ($56,305.25)
BACKGROUND
A professional services agreement for design services for the Libbey-Nicolet North Main Street Area Detention
Basin with AECOM was approved by the Common Council on May 26, 2015. During the course of this project,
several additional engineering-related services were requested by City staff.
ANALYSIS
The additional services requested included conducting additional soil borings onsite; constructing a groundwater
model to estimate groundwater flow and determine the potential impact of groundwater on the project; developing
a long-term groundwater dewatering model to estimate the potential impact on adjacent properties due to long-term
groundwater dewatering activities; designing and preparing specifications for a long-term groundwater dewatering
system to reduce the likelihood of damage to the project from groundwater; and preparing project specifications
and coordinating with the Fernau Watershed — North Main Street Area Wet Detention Basin for bidding together as
a single large project.
FISCAL IMPACT
Staff has reviewed the amendment and costs. The amount of this agreement amendment is $56,305.25. This will
raise the total agreement amount to $245,905.25 (not to exceed). These services will be funded through the Storm
Water Utility. Funding is available within the 2015 Storm Water Utility portion of the Capital Improvement Program
for these services.
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
amendment and in accordance with Section 12-16 of the Code, I am hereby recommending that the Common
Council approve this amendment.
Approved,
