About this file
This document provides specifications for surge protective devices and summarizes a federal contract opportunity for the upgrade of a chiller plant at the John L. McClellan VA Medical Center in Little Rock, Arkansas. The specifications outline technical requirements for switchgear, switchboard, and panelboard SPDs including surge current ratings, modular or non-modular design, integral disconnect switches, status indicators, and monitoring contacts. The federal contract opportunity involves providing all materials, equipment, labor and expertise for the chiller plant upgrade project with an estimated value between $1 million to $2.5 million. The solicitation will be issued on or around March 18, 2021 and has been set aside solely for service-disabled veteran owned small businesses under NAICS code 236220 for construction of new commercial and institutional buildings with a size standard of $36.5 million.
