How to Bid Federal Contracts in NAICS 561621

USACE and DHS (FPS and CBP) are the two largest federal buyers. Many classified-facility installations require a Facility Security Clearance (FCL) and DD-254 Contract Security Classification Specification. UL Listing (UL 681 for burglar alarm, UL 864 for fire) is typically required by agency specifications. Most federal security-systems contracts are set aside for small business; SDVOSB set-asides appear frequently on VA campus projects.
