The U.S. Department of Labor, on behalf of the Mine Safety and Health Administration, requires electrical wiring and conduit replacement at the MSHA Approval and Certification Center Building 4 in Triadelphia, West Virginia. The performance period runs from award receipt through 45 days after award. This is a total small business set-aside resulting in a single award, using lowest priced technically acceptable source selection. Site visits are permitted but at the offeror's own expense, and coordination is required with the designated government contacts.
