The National Nuclear Security Administration’s (NNSA) Nevada Field Office is seeking small business sources for technical surveillance countermeasures (TSCM) support at the Nevada National Security Site, National Security Technologies offices in Livermore, Calif. and Los Alamos, N.M., and other sites, according to a sources sought notice posted last week. The Department of Energy’s TSCM program seeks to detect and deter technical security hazards and protect classified and sensitive material from technical surveillance intrusions. The TSCM support services contractor will contribute to the program’s facility surveys, inspections, monitoring, briefing, and other functions intended to identify technical security vulnerabilities, according to the draft performance work statement. The contract period of performance is expected to consist of a 12-month base period with four 12-month option periods, and responses must be submitted through www.fedconnect.net by Jan. 29.
