About this file
This document is a Lightning Protection Plan technical drawing for a facility, detailing the installation of lightning protection systems across a building's roof and exterior. The plan includes multiple air terminal masts positioned strategically around the building's perimeter, with each mast specified to be installed at a minimum height of 15'-6" above the roof. The technical drawing provides side and end view perspectives, along with a detailed legend explaining the lightning protection cable specifications, including 24-gauge stranded aluminum wire and 228 copper conductor connections. Key installation components include Superstrut support clamps, bronze bonding connections, and specific mounting instructions for the air terminals. The drawing appears to be part of a Department of Air Force Space Command project (Solicitation Number 21CONSLPSSmith) for lightning protection system repairs, with precise technical specifications for ensuring comprehensive lightning protection for the facility.
