The Notre Dame HVAC Upgrade project aimed to modernize the school’s heating and cooling systems, replacing steam convectors with three Riello boilers, a Trane AHU, and VAV systems. It also involved some EX fan replacements and gas line rerouting. Despite a challenging schedule of over 12,700 working hours in a short time frame, Phase 1 of a larger project was successfully completed.

Processes included carbon steel piping for gas lines, press copper for water, and general commercial ducting for HVAC distribution.

The project was executed successfully with large pipefitting and sheet metal crews, alongside a smaller plumbing scope. Use of Value Engineering (VE) in the mechanical room, as well as Tweet/Garot’s Building Automation Systems (BAS) coordination and adherence to schedule, contributed to the project’s success.

Key challenges included the demanding schedule, duct fabrication delays, steel revisions on-site, and parts and equipment delivery delays.
The Notre Dame HVAC Upgrade project efficiently addressed the school’s HVAC needs, overcoming tight schedules and various challenges. This accomplishment sets the stage for the school’s future phases of renovation.
