South Main Street Sidewalk

The City of Ann Arbor is soliciting bids to construct a new ADA‑compliant concrete sidewalk system along South Main Street, including demolition of existing pavement, earthwork, soldier‑pile and cast‑in‑place retaining walls, storm‑sewer pipe installation, utility relocation, traffic‑control devices, lighting, signage, fencing, and final turf restoration. The contract is a fixed‑price, unit‑price public‑improvement construction award with strict wage (prevailing and living‑wage) and non‑discrimination compliance requirements. Work must be substantially completed by August 28 2026 (turf by September 30 2026) with a 5 % bid security and a 120‑day bid validity period. • Scope covers concrete sidewalks, curb‑and‑gutter, detectable warning surfaces, ramps, retaining walls, storm‑sewer pipe, utility and signal work, temporary fencing, erosion control, and landscaping. • Mandatory bid attachments include general declarations, prevailing‑wage, living‑wage, conflict‑of‑interest, and non‑discrimination forms. • The project is phased (East side Phase 1, West side Phases 2A/2B) and must avoid several “no‑work” dates (Memorial Day, Independence Day, Art Fair, Labor Day, UM football home games).
