About this file
This document is a combined synopsis/solicitation for an Arc Flash Analysis contract issued by the Department of Veterans Affairs (VA) for the VA Loma Linda Healthcare System (VALLHCS) in Loma Linda, California.
The VA is seeking to award a one-year contract to provide an Arc Flash Analysis of the VALLHCS electrical distribution system, including transformers, power panels, load centers, and disconnects. The contractor will be required to collect system data, perform an Arc Flash analysis, provide a written report, and place Arc Flash warning labels on all evaluated equipment. The work must comply with OSHA, NFPA, IEEE, and other industry standards. The solicitation is set-aside for 100% Service-Disabled Veteran-Owned Small Businesses (SDVOSB). Responses are due by August 23, 2024, and a site visit is scheduled for August 19, 2024. Award will be based on a comparative evaluation of price and past performance, with price being the more important factor.
