This is a rebid of mechanical work only; other prime contracts have already been awarded. Davis-Bacon federal wage rates apply, as this is a HUD-funded project.

A bid bond equivalent to 5 percent of the bid price is required for bids exceeding $50,000. Upon award, the successful bidder must provide performance and payment bonds equal to 100 percent of the contract price or alternative guarantees. Progress payments are made at 30-day intervals with 10 percent retainage held until final completion. Liquidated damages are assessed at $500 per calendar day for schedule overruns.

Required insurance includes workers' compensation, general liability with a minimum $1 million coverage naming ACHA as additional insured, builders' risk, and automobile insurance with $1 million combined single limit. The contractor must maintain all applicable federal, state, and local licensing and permits and comply with Equal Employment Opportunity and supplier diversity requirements, including consideration of small, minority, and women-owned businesses.
