The City of Ann Arbor Procurement Unit is requesting proposals for electrical preventative maintenance services at the Wastewater Treatment Plant under RFP #26-43, with proposals due September 9, 2026 at 2:00 p.m. local time. A mandatory pre-proposal meeting is scheduled for August 25, 2026 at 11:00 a.m. at the WWTP Administration Building; failure to attend results in automatic disqualification.

Work requiring de-energization of system components requires minimum two-day notice to WWTP operations staff.

The contractor must comply with prevailing wage requirements under Ann Arbor City Code Chapter 14 and living wage provisions under Chapter 23 (currently $17.42/hour with health benefits or $19.42/hour without). Commercial General Liability Insurance of $1,000,000 per occurrence and $2,000,000 per project aggregate, Workers' Compensation Insurance, Motor Vehicle Liability Insurance of $1,000,000, and Umbrella/Excess Liability Insurance of $1,000,000 are required.
