About this file

Written by GovTribe AI · Apr 3, 2024

This document appears to be a set of mechanical and plumbing drawings and specifications for a cooling system upgrade project at the Meadows Elementary School, located in Portland, Oregon. The project involves installing new rooftop condensing units and wall-mounted fan coil units to provide cooling for the main office and support spaces at the school. The document includes a list of equipment, schedules, and details for the new HVAC system components, as well as notes on the controls integration with the existing building automation system.

The related state and local contract opportunity appears to be for the Centennial 4 - Site Mechanical Cooling project, which includes multiple sites in Multnomah County and the City of Portland, Oregon. This is likely a separate but related project to the Meadows Elementary School cooling upgrade.
