9-series AsBuilts Bldg 101 Limited for Release.pdf

This file contains mechanical engineering drawings and schematics for Building 101's HVAC systems at NIST's Gaithersburg campus. The drawings detail various HVAC system components including air handling units (labeled ACU-A1 through ACU-E6), ductwork layouts, perimeter systems, tower air and water risers, and mechanical equipment pads.

The drawings show detailed floor plans, sections, and elevations depicting the HVAC infrastructure throughout the building's tower section. Key components illustrated include supply and return air ductwork routing, equipment locations, mechanical room layouts, and system connection details. Specific technical information is provided about air flow rates, water flow rates, and equipment specifications. The drawings include both plan views and cross-sectional details of the mechanical systems, along with installation details for items like pipe supports, duct hangers, and equipment mounting. These appear to be as-built drawings that document the existing HVAC systems that would be relevant for the planned renovation work described in the contract opportunity.
