About this file

This is a Suspect Material Inventory Summary document for the NIST MD Administration building's mezzanine mechanical rooms (A150A, A150B, and A150C), which catalogs potentially hazardous materials and their asbestos-containing material (ACM) determinations. The document appears to be supporting documentation for a HVAC tower renovation project.

The inventory details various materials found in three mechanical rooms of similar dimensions (all 45 feet East/West length and 12 feet height, with varying North/South lengths of 87, 40, and 80 feet respectively). The materials listed include ACM-confirmed items such as gray pliable caulk (CK04), duct insulation (DI01), and brown pin mastic (MA09) associated with duct fiberglass insulation. Several Presumed ACM (PACM) materials are identified, including electrical insulators (EI01), fire doors (FD01), and miscellaneous gasket materials (GM01). The document also lists materials determined to be non-detect (ND) for asbestos, such as gray latex-like duct sealant (DS04), light red firestop material (FSM02), and cloth HVAC vibration collars (HVC01). The inventory is dated February 20, 2025.
