Repl HVAC & Mechanical Room Doors, Cottages A-E, Hawthorn Children's Psychiatric Hospital

This project involves the replacement of existing HVAC split systems (two furnaces and one condensing unit) in five cottages of the Hawthorn Children’s Psychiatric Hospital, including ductwork modifications, installation of new exterior hollow‑metal doors and frames for each mechanical room, removal and replacement of adjacent drywall ceilings, and the substitution of tank‑type water heaters with tankless units in four cottages. The work is focused on mechanical and building envelope upgrades to improve energy efficiency and meet updated code requirements. • Replace HVAC furnaces and condensing units, modify ductwork as needed. • Install new exterior hollow‑metal doors & frames for each mechanical room. • Replace existing tank‑type water heaters with tankless, instantaneous service units in four cottages. • Remove and reinstall drywall ceilings adjacent to mechanical rooms to accommodate duct work changes. • Provide full construction drawings and specifications for the above scope.
