RTU replacement - phase 2 sabbath middle school

The School District of the City of River Rouge is seeking sealed proposals for a rooftop unit (RTU) replacement project at Clarence B. Sabbath Middle School located in Wayne County, Michigan. The procurement involves replacing three existing packaged multi-zone rooftop units (RTU-2, RTU-4 & RTU-9), which requires comprehensive installation of associated gas piping, electrical systems, and building controls. Specific project deliverables include pre-demolition airflow testing, final air balance, new direct digital control (DDC) and wired thermostats for each system, and integration with the existing Tridium Niagara Building Management System (BMS). Bidders must submit a 5% bid bond from an authorized surety company or certified check with their proposal. The mandatory pre-bid meeting and walk-through for prime mechanical contractors is scheduled for June 8, 2018, at 10:00 am at the school site. Sealed proposals are due by 10:00 am local time on June 15, 2018, at 1460 W. Coolidge Highway, River Rouge, MI, with a project start date of June 21, 2018, and substantial completion required by October 31, 2018.

The contract specifications indicate Seasons-4 Direct Replacement Rooftop Units as the approved manufacturer, which suggests potential limitations on equipment substitutions. Bidding documents are available electronically through MacMillan Associates, Inc., the project engineer, via their FTP site. The successful bidder must furnish 100% performance and labor/material bonds, and bids must remain valid for 30 days after opening. While no specific set-aside designations for disadvantaged enterprises are mentioned, the school district reserves the right to reject any and all bids. The bidding documents do not specify a precise budget range, but the comprehensive scope of work involving multiple rooftop units, associated mechanical and electrical systems, and controls integration suggests a substantial project investment. Potential bidders should be prepared to demonstrate significant mechanical and HVAC system replacement experience, particularly with school district infrastructure.
