Questions from employers in this region
Fort Huachuca houses Army intelligence and cyber operations — what DOD testing requirements apply?
All contractors performing work at Fort Huachuca under federal contracts are subject to DOD contractor drug-free workplace requirements under FAR 52.223-6. Given the sensitive intelligence and cyber mission nature of Fort Huachuca work, contractor programs may have additional security-related requirements beyond standard FAR. We coordinate collections at Fort Huachuca coordinated with installation security and contractor program management.
Sierra Vista is very remote — is on-site testing the only practical option?
Sierra Vista / Fort Huachuca is approximately 75 miles from Tucson and 30+ miles from the next-nearest clinic. For Fort Huachuca contractors, UAV test range employees, and Cochise County construction employers, on-site mobile testing is the only practical compliance solution. We come to your Sierra Vista or Fort Huachuca facility.
