Cornerstone Commissioning, LLC, a small business division of Contamination Control And Certification Holdings, Inc., provides building commissioning and performance verification services to federal agencies as a prime contractor (86% of recent awards), competing predominantly under Total Small Business set-asides. The Winchester, Massachusetts–headquartered firm specializes in commissioning authority (CXA) services for research laboratories, biosafety facilities, and office buildings, with work spanning architectural and engineering assessment, roof replacement commissioning, and Biosafety Level 3 performance verification across EPA analytical facilities and veteran healthcare sites nationwide.
Cornerstone's customer base concentrates at the Environmental Protection Agency, which accounts for four awards and $10.3 million of the vendor's $10.7 million combined potential value across all recent awards. The EPA's Office of Administration and Resource Management and the Department of Veterans Affairs Veterans Integrated Service Network 21 each sustain two awards; the National Institutes of Health, CDC, and Army Materiel Command Research Development and Engineering Command round out active customer agencies. The vendor holds a seat on the EPA's Commissioning Authority (CXA) Services IDIQ, a $10 million multiple-award Total Small Business contract running through March 13, 2027, from which five delivery orders totaling $442 thousand have been placed. Task orders under the IDIQ range from $25,000 to $250,000 and cover commissioning at the Athens Main Lab, Manchester Laboratory roofing assessment, Narragansett roof replacement, Fort Meade ESC roof replacement, and Phase 2B commissioning at the Athens Environmental Center.
