About this file

Written by GovTribe AI ·

This is a mechanical floor plan sheet showing demolition and new work plans for a chiller replacement project at a high school in Oregon. The plans detail the removal of an existing chiller, chilled water pump, heating water pump, and inline heating water pump, along with their associated concrete housekeeping pads and piping connections in the boiler room (G31) and adjacent storage room (G32).

The new work plan shows the installation of a new air-cooled high efficiency chiller with the same or smaller footprint as the existing unit, new base-mounted chilled water pump with VFD, new base-mounted heating water pump with VFD, and new inline heating water pump with VFD. All new equipment must be tied into the existing DDC system and installed according to 2021 Oregon Mechanical Specialty Code and 2019 Oregon Energy Efficiency Specialty Code requirements. The plans include piping modifications for chilled water and heating water systems, with all new piping to be insulated as required by Oregon Energy Code.
