Reference Document As-Builts.pdf

This is a reference document containing as-built drawings for the ODOT Building A HVAC Controls Replacement project in Oregon. The document provides technical specifications and visual representations of the existing HVAC control systems at the facility prior to the proposed replacement work. These as-built documents serve as baseline reference materials for bidders and contractors to understand the current system configuration, equipment layout, and control infrastructure that will be modified or replaced during the project. The drawings detail the existing mechanical systems, control points, sensor locations, and operational parameters that contractors must account for when planning the HVAC controls upgrade.

The as-built reference materials are essential for accurate project scoping and bid preparation, as they establish the existing conditions against which the new energy-efficient controls system will be designed and installed. Bidders can utilize these technical documents to identify all labor, materials, equipment, and services necessary to complete the modernization work, including system disconnection, new control installation, testing, and commissioning. The reference drawings enable contractors to assess site-specific challenges, compatibility requirements, and integration needs for the proposed controls replacement to improve energy efficiency and simplify operational management of HVAC units for ODOT's benefit.
