The U.S. Army intends to issue a sole-source contract modification to increase the existing contract ceiling by $99.92M for the continued fielding and service of the ICIDS-VI security system. This action supports a new fielding plan requiring installations across the U.S. and abroad, including 10-year service life replacements. The government has determined the incumbent contractor, Evergreen Fire and Security in Tacoma, WA, is the only source capable of performing this specialized continuation of work without unacceptable cost or delay. While not a request for proposals, firms believing they can provide identical support may submit a capability statement for government review.
