The scope of this project includes, but is not limited to, HVAC Upgrades and Masonry Repairs to the 1930s / Auditorium / Cafeteria Wing, the Annex, and the Science Wing at Millburn Middle School. The project shall be broken up in two scopes of work: Phase A and Phase B.

Phase A is limited to ventilation upgrades and shall include the removal and replacement of five (5) rooftop ventilation units over the Annex, 1930’s Wing, and Science Wing. The five (5) water source heat pump rooftop Energy Recovery Units (ERU’s) will be replaced with packaged rooftop ERU’s that use direct refrigerant expansion (DX) for cooling and natural gas for heating the ventilation air; these units will feed the Annex, 1930’s Wing, and Science Wing via existing ventilation / exhaust ductwork, and will be controlled through the existing Automated Building Management System.

Phase B shall include heating / air conditioning upgrades, upgrades to ventilation ductwork served by the ERU’s replaced in Phase A, and exterior masonry repairs / restoration. The heating / air conditioning upgrades shall involve the removal of existing unit ventilators, ground source heat pumps, and air handlers serving the Annex, 1930s/Cafeteria/Auditorium Wing, and Science Wing. These system(s) shall be replaced with new VRF units serving the 1930 Wing and Annex, a new RTU serving the 1930 Library, and new boiler plants, a new Air Handler / modified RTU’s serving the Auditorium / Cafeteria; all of these systems shall be controlled through the existing Automated Building Management System. Phase B shall be phased, as outlined in below.
