South Lyon City Council on Aug. 25 approved a contract and budget amendment to replace the roof on the maintenance and control building at the city wastewater treatment plant, authorizing an amount not to exceed $519,067.

The project, presented by water department staff, replaces a deteriorated multi-layer asphalt roof installed in 2003 and addresses leaks over sensitive sections of the building. The council also approved an amendment to the water-and-sewer fund budget line item 592-557-972 to increase the allocation from $475,000 to $519,067 to cover the adjusted contract price.

City Attorney Lisa said the original contractor proposal contained terms the city could not accept, including indemnification language, waiver of subrogation, and mandatory arbitration. “There were a number of provisions in those terms and conditions that the City cannot agree to, such as indemnification and subrogation of insurance,” she said, and told council that the contractor agreed to four changes requested by the city, including naming the city as additional insured on the contractor’s policy and making arbitration discretionary.

Bloom Roofing of Brighton was the low bidder. Staff recommended Bloom Roofing’s base bid of $494,267 plus a 5 percent contingency ($24,800) for a total not to exceed $519,067; staff said the contingency covers anticipated items such as replacement of leaking skylights. Council member Critzwell asked how many bids were received; staff said three and that Bloom’s was the lowest, and that the other bids did not expressly include contingency in the same way.

Council member Hanson moved to amend the water and sewer fund budget to $519,067 and later moved to approve the roof replacement under the amended agreement. Council approved both motions by roll-call vote.

The city attorney advised council that the contractor had agreed to the revised contract language the day of the meeting but the terms presented in the packet did not yet reflect the agreed edits; staff said motions could be approved “as amended.” The motion approved the contract subject to the amended terms agreed with the contractor.

The city indicated the work is a budgeted capital improvement for FY 2025–26 and materials supporting the recommendation included the bid sheet, roof-section photos, and HRC specifications. The procurement will proceed under the amended contract terms and with the contingency funds added into the budget line.
