About this file

Written by GovTribe AI · Feb 4, 2025

This is a set of mechanical, electrical and fire alarm system drawings for HVAC equipment replacement and refurbishment in Building 101 at NIST's Gaithersburg, MD campus. The drawings detail the replacement of six air conditioning units (ACU-A-1 through ACU-A-6) and associated return/exhaust fans located in the Mezzanine A mechanical equipment room.

The drawings include demolition and new work plans showing HVAC equipment layouts, ductwork, piping, controls, electrical power distribution through motor control centers MCC-A1 and MCC-A2, and fire alarm system modifications. Detailed specifications cover air handling unit components like cooling coils, heating coils, filters, humidifiers, and variable frequency drives. The work requires careful phasing since only one air handling system can be taken offline at a time over weekends. New duct smoke detectors will replace existing firestats, and the fire alarm system will be modified accordingly while maintaining system operation. The drawings provide comprehensive details for mechanical, electrical, and fire protection contractors to execute the HVAC renovation work.
