About the company
Construction Technology Laboratories Inc., doing business as Ctlgroup, is a self-certified small disadvantaged business that provides concrete testing, strain-gauge instrumentation, technical training, and materials-science consulting services to federal agencies as a prime contractor (89% of awards) and occasionally as a subcontractor. The company is a child entity of the Portland Cement Association, a nonprofit based in Washington, D.C., and operates from Mt Prospect, Illinois, with primary NAICS coding in testing laboratories and services, heavy civil engineering construction, and engineering services.
Ctlgroup's recent federal work spans concrete technology consulting, structural instrumentation, and expert witness services across multiple transportation and infrastructure agencies. Representative prime contracts include a $566,264 definitive contract awarded by the Nuclear Regulatory Commission on August 20, 2024, for concrete technology and codes training delivered to NRC staff through August 2029 (base plus four one-year options); a $51,200 purchase order from the Department of Defense Civilian branch on September 23, 2026, for 36 CTL Group concrete strain gauges with 300 feet of lead wire; and a $1,168 purchase order from the Department of Justice Civil Division on August 13, 2024, for expert witness services. Ctlgroup subcontracts concrete testing and materials expertise to primes including Stantec Consulting Services on a concrete semi-adiabatic temperature testing sub-award for the Rough River Dam Safety Modification and to Manson Construction on the Pier 6 Replacement project at Naval Base San Diego, where it served as concrete provider.
Customer concentration skews toward transportation and infrastructure agencies. The Department of Transportation Federal Highway Administration accounts for 20 awards and $7.9 million in combined potential value, anchoring 37% of the dollar base across the portfolio. The Nuclear Regulatory Commission, the Department of the Army Corps of Engineers, and the National Institute of Standards and Technology round out the top value customers. Ctlgroup maintains positions on the Waterfront MACC IV contract vehicle (9 task orders) and two Federal Highway Administration indefinite delivery contracts, though vehicle concentration is modest relative to overall portfolio spread. The vendor serves 25 distinct federal customer agencies across 88 total awards, with prime activity concentrated in testing and research work rather than direct construction delivery. Only one award faces ultimate completion within the next twenty-four months, presenting minimal near-term recompete pressure. Recent obligated dollars total $15.4 million against $18.4 million in combined potential value, indicating 84% cash-flow maturity across the existing award base.
