From the notice

GENERAL: Introduction: An inspection for current code compliance of the lightning Protection System on Building 71N has been conducted and found the system needs upgrades and repairs to meet current NFPA 780 and UL96A standards. The Sheridan VA Medical Center needs the services of a qualified contractor to perform the needed lightning protection upgrades to the main hospital building 71N. Located on the Sheridan Wyoming Veterans Affairs Medical Center (VAMC) campus, at 1898 Fort Road, Sheridan, Wyoming 82801. Statement of Work: Specifics a. Existing Conditions The existing lightning protection system (LPS) for Building 71N was installed in 1989 during the building s original construction. Overall, the system remains in fair condition, though it requires repair because several air terminals have become detached from their adhesive bonds to the roof surface. Air terminals are present at all high points of the structure, and all roof-mounted equipment and appurtenances are properly grounded. A main grounding bus connects the communication systems and possibly the electrical distribution system to the primary service ground. The specific location where the grounding system bonds together the structural steel, electrical system, lightning protection components, and plumbing to create an equipotential ground could not be identified during the assessment. A continuous grounding loop encircles Buildings 9, 71, and 71N, with all roof air terminals and down conductors tied into this loop. Down conductors descend to the loop at the corners of each of these buildings.
