About this file
This is a specification document for door hardware (Section 08 71 00) prepared for federal construction projects, specifically designed for Department of Veterans Affairs (VA) facilities. The specification establishes comprehensive requirements for all door hardware components necessary for complete installation and operation of doors in VA Medical Centers (VAMCs).
The specification details extensive product requirements organized into multiple hardware sets (HW-1 through HW-12 with various lettered variations) that correspond to specific door types and applications throughout the facility. Required hardware components include butt hinges, continuous hinges, door closers, floor closers and pivots, door stops, overhead stops and holders, locks and latches (mortise, cylindrical, push-button combination, electromagnetic, and electric strikes), exit devices, flush bolts, key cabinets, armor plates, kick plates, mop plates, door pulls, push plates, coordinators, thresholds, weatherstrips, and miscellaneous hardware items. All products must comply with ANSI/BHMA standards, NFPA requirements for fire-rated assemblies, ASTM specifications, and UL listing requirements where applicable. The specification mandates that hardware finishes conform to ANSI A156.18 standards, with specific finish designations (626, 630, 652) for different applications and base metals. Installation requirements include detailed hardware heights for centerline placement (ranging from 1024 mm for locksets to 1270 mm for push plates), hinge quantity specifications based on door height and width, and preinstallation meeting requirements with VA Locksmith involvement. Warranty provisions specify two-year coverage for automatic door operators, five years for locks and panic hardware, and ten years for door closers and continuous hinges. The specification includes provisions for new keying systems utilizing removable core cylinders with patent-protected key blanks and controlled distribution, along with detailed submission requirements for hardware schedules, shop drawings, product data, and certificates of compliance. Special applications addressed include ligature-resistant door alarms for Mental and Behavioral Health areas, lead-lined doors, RF-shielded doors, and automatic door operators (ADOs) with electric strikes and power transfer hinges. The document serves as a template with bracketed notes for specification writers to customize based on project-specific requirements, including guidance on selecting between materials (stainless steel versus standard steel) and hardware configurations based on environmental exposure and security needs.
