HEPA Filter Drawing with Counts.pdf

This is a detailed architectural floor plan for Part Level 1 of a clean room facility, specifically showing the reflected ceiling plan for demolition and new work. The document is prepared for NIST (National Institute of Standards and Technology) and includes the project identifier "NIST FY 2024 CFPB" on Sheet ID 215-468.

The floor plan illustrates a large clean room space with multiple parallel structures indicated by hatched sections, likely representing environmental control systems or containment areas. The plan includes a comprehensive legend identifying four types of diffusers: return grilles, return grilles, blank ceiling panels, and exhaust grilles. Circled numbers throughout the drawing reference specific components and installation points. General notes specify requirements for material procurement, coordination with other trades for clearance, repair of damaged materials, and replacement of existing HVAC returns and grilles. Drawing notes address the replacement of existing ceiling returns, the proper installation of grilles with coordination between mechanical contractors and structural elements, and the replacement of ceiling grilles to match existing specifications. The document contains architectural specifications for construction work involving HVAC systems, ceiling infrastructure, and related building systems at this federal facility.
