• Details on demolition and new work for HVAC systems.
• Schedules for Air Handling Units (AHUs), Exhaust Fans, HEPA Devices, Air Flow Measuring Stations, and Duct Construction.
• Control diagrams for various air handling and exhaust systems.
• Installation details for exposed air ducts, pressure gauges, and variable air volume terminals.
• General and drawing-specific notes regarding rebalancing procedures, pressure differentials, and equipment specifications.

These drawings are critical for bidders to understand the physical scope of the "Cleanroom Re-Balance" project. They provide detailed information on existing and proposed ductwork, piping, air handling units, exhaust systems, and equipment locations. Bidders must review these drawings to accurately assess the work required, develop their proposals, and understand the project's complexity and technical requirements, particularly concerning airflow management, equipment needs, and control system integration.

This document is a "Basis of Design Report" for the "Cleanroom Re-Balance" of Building 215 at the National Institute of Standards and Technology (NIST) facility in Gaithersburg, Maryland. It was prepared by Burdette, Koehler, Murphy and Associates, Inc. (BKM) and dated December 6, 2019. The report details the existing conditions of the air systems within Building 215, analyzes identified deficiencies, and provides recommendations for corrections. These recommendations include repair or replacement of VAV terminal units, airflow measuring stations (AFMs), magnehelic gauges, HEPA filters, and ductwork. It also addresses correct pathways for return air and testing of air handling units (AHUs) and exhaust fans (EFs).

This document provides crucial background information on the existing HVAC systems and their deficiencies within Building 215. It outlines the scope of work required for rebalancing the cleanroom airflows to meet current installed equipment requirements. Bidders can use this report to understand the existing conditions, the identified problems, and the general recommendations that will form the basis for construction documents. The report also references appendices containing drawings, existing photos, and a previous AECOM report, which would be essential for developing a comprehensive proposal.
