About this file

Written by GovTribe AI · Aug 26, 2025

These documents are construction bid documents for the Rooftop Unit Replacement project for the Michigan State Office Building located at 305 Ludington St, Escanaba, MI, prepared by OHM Advisors for the Department of Technology, Management and Budget (DTMB) State Facilities Administration Design and Construction Division. The project involves replacing the existing rooftop unit (RTU-1) with a new Carrier 48K3HM30 rooftop unit, which will serve multiple floors and rooms totaling approximately 23,800 square feet. The bid documents are dated August 1, 2025, with a project number of 7136-24-0110 and DTMB File No. 171/24438.JBB.

The new rooftop unit is specified with detailed technical requirements, including a 13,500 CFM supply air capacity, 1,900 CFM outside air, 15 HP supply fan, DX cooling with 312 MBH total capacity, and an 800 MBH gas heating section. The unit will feature multi-stage high gas heat, digital scroll modulating cooling, variable frequency drives, 100% comparative enthalpy economizer, hot gas reheat coil, and BACnet control interface. Electrical and mechanical plans indicate the replacement will involve removing existing equipment, preparing new roof curbs, connecting gas and electrical services, and integrating with the building's existing Building Automation System. The project scope includes comprehensive demolition, installation, and system integration work to ensure minimal disruption to the state office building's operations.
