Attachment 2 - Drawings.pdf

This is an attachment containing engineering drawings for a Building 215 Clean Room HEPA Filter Replacement project at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. The drawings provide technical specifications and visual representations for the renovation work within the Advanced Measurement Laboratory (AML) cleanroom facility, which houses an 1,800 square meter cleanroom with 750 square meters designated as Class 100 classification. The drawings support the design completed by Burdette Koehler Murphy Associates Inc. and illustrate the mechanical, HVAC, and ductwork modifications required for the comprehensive facility upgrade.

The project scope includes replacement of approximately 1,200 existing terminal supply HEPA filters, repair or replacement of ~70 variable air volume terminal units, installation of ~32 new exhaust air valves, replacement of ~54 airflow monitors, and ductwork modifications. The drawings depict the facility layout, equipment locations, and interconnections necessary for executing the work while managing operational constraints. This is a Total Small Business set-aside under NAICS code 236220 with a $45.0 Million size standard, and the government anticipates awarding a single firm fixed price contract. The construction contractor must limit operational outages through careful scheduling and planning, as the customer requirement has evolved from the original 16-19 month continuous shutdown scenario contemplated during design.
