High-Level Trunkline Capacity Improvements Project

The City of Ann Arbor Public Services / Engineering is seeking a construction services firm for the High-Level Trunkline Capacity Improvements Project through a Request for Proposal (RFP) issued with the identifier RFP No. 25-39. The primary objective is to install a new 36-inch fiberglass reinforced plastic (FRP) gravity sanitary sewer line utilizing microtunneling trenchless construction techniques, extending from Miller Avenue down First Street and then along Washington Street for approximately 520 feet. The project involves comprehensive infrastructure improvements, including storm sewer work, water main installations, street and sidewalk improvements, and associated civil works. Proposals are due on October 30, 2025, by 11:00 a.m. local time, with a mandatory pre-proposal conference scheduled for September 29, 2025, at 10:00 a.m. The evaluation will be based on a 100-point system, with points distributed across qualifications (20 points), workplace safety (20 points), workforce development (20 points), social equity and sustainability (20 points), and schedule of pricing/cost (20 points). Proposals must remain valid for 120 days, with the City anticipating contractor selection in November 2025 and City Council authorization in December 2025.

The RFP does not explicitly specify set-aside designations for disadvantaged enterprises, though the evaluation criteria suggest a focus on social equity and workforce development. Bidders must provide bid security of 5% of the total bid price and comply with prevailing wage requirements. The project includes environmental management provisions for contaminated soil and groundwater, requiring detailed documentation of regulatory compliance. While no incumbent vendors are mentioned, the project involves sophisticated infrastructure improvements with specific technical requirements, including monitoring systems such as inclinometer installations, settlement monitoring points, utility monitoring points, and observation wells. The total project value encompasses multiple line items for infrastructure components, with the base bid covering extensive civil works. Contractors will need to demonstrate expertise in trenchless construction techniques, urban infrastructure development, and environmental management, with a strong emphasis on minimizing disruption to the existing urban environment.
