About this file

This document appears to be a file related to a state and local contract opportunity for a project involving mechanical repairs and controls replacement at multiple buildings across various jurisdictions in Oregon, including Multnomah County and the City of Portland. The project requires the installation of a new rooftop unit (RTU) with detailed specifications provided, including seismic design criteria, load calculations, and installation requirements. The document also includes technical data sheets for the proposed RTU model, including physical dimensions, electrical data, and airflow specifications.

The related state and local contract opportunity covers mechanical repairs and controls replacement at 5 sites across multiple jurisdictions in Oregon. The project is seeking bids from qualified contractors to perform the necessary work, with a focus on addressing seismic design and compliance with the 2018 International Building Code. The document does not provide specific details on the contract term, award dates, or other procurement-related information.
