HomeMy WebLinkAboutVIII-09 Authorize Signature of WSB Construction Support Services for the Central WTP and Raw Watermain ProjectsCity Council Memorandum
To: Mayor Fasbender & City Council Members
From: Dan Wietecha – City Administrator
Date: August 18, 2025
Item: Authorize Signature of the WSB Construction Support Services for the Central WTP and Raw
Watermain Projects
Council Action Requested:
Enclosed for City Council consideration is the WSB Amendment for Additional Services No. 1 that
includes construction support services necessary for the Central WTP and Raw Watermain Projects.
Background Information:
The design and bidding for the Central WTP and Raw Watermain Projects was completed by WSB and
this work was fully funded by the MPCA Grant Agreement for Drinking Water Planning and Design Funds
for PFAS Treatment. Now that the projects are moving forward into the construction phase, support
services such as observation, administration, staking, and testing are necessary to facilitate construction.
Financial Impact:
The estimated cost of these services is $1,270,373, which is within the total financial budget of the
project. The MPCA Grant Agreement for the Central Water Treatment Plant authorized at the August 8th
City Council Meeting identifies that 3M Settlement Funds will cover 90% of the construction support
services for this project. The remaining costs are covered in the PFA Loan/Grant Agreement funds.
