About this file

Written by GovTribe AI ·

This file is a technical architectural drawing specifying a B1_ Wall Type for a construction project, detailing fire-rated and sound-tested wall specifications for a VA Medical Center infrastructure upgrade. The drawing provides comprehensive technical details for a 3 5/8" metal stud wall with a 4 7/8" total wall width, featuring a one-hour fire rating (UL U465) and a Sound Transmission Class (STC) rating of 40.

Key technical specifications include full-height metal studs at 16" on-center, 5/8" gypsum board on both sides, sound attenuation insulation (3 1/2" thick), deflection tracks, acoustic/fire sealant, and specific mounting details for metal tracks to concrete floor decks using 1 1/2" powder-activated fasteners. The drawing includes multiple section views (head parallel to metal deck, head perpendicular to metal deck, and plan section) and notes that impact-resistant gypsum board can be used on one or both sides equivalently, with reference to specific Underwriters Laboratories (UL) design systems and test numbers.
