About this file

Written by GovTribe AI · Jul 31, 2024

This document is a set of drawings and technical specifications for the addition of an Energy Recovery Ventilator (ERV) HVAC system to the Science Classrooms at Bromfield High School in Harvard, Massachusetts. The project involves the installation of new mechanical, electrical, and controls equipment, including an air-cooled condensing unit, air handling unit, and associated ductwork, piping, and controls. The project drawings and specifications provide detailed information on the equipment, layout, and installation requirements.

The related state and local contract opportunity is for the replacement of two existing Heat Recovery Units (HRU-1 and HRU-2) at an unspecified location in Worcester County, Massachusetts. The successful bidder will be responsible for all subcontracted work related to roofing, electrical, and plumbing. No additional details are provided regarding pricing terms, set-asides, incumbent contractors, funding sources, or contract duration.
