What CEMS Engineering does
CEMS Engineering, Inc. is a privately held, multi-discipline architecture and engineering (A/E) firm founded in 1989 and headquartered in Summerville, South Carolina, with a regional office in Wilmington, North Carolina. The firm delivers integrated design services across architecture, interior design, civil, electrical, mechanical, structural, fire protection, GIS, and building commissioning, operating as a single-source A/E provider rather than a software or product company. Its underlying technical stack centers on conventional engineering tooling and standards (HEC-RAS and SWMM hydraulic modeling, ASHRAE 90.1 energy compliance, LEED certification workflows, energy modeling, life-cycle analysis, and BIM-style coordinated design) rather than proprietary software platforms.
The firm's revenue model is professional-services fees billed against project scopes, executed under design-bid-build, design-build, and construction administration delivery methods. Its go-to-market is split between a federal channel (70+ annual IDIQ contracts with USACE, GSA, NAVFAC, USAF, DHS, and VA, plus a Mentor-Protégé JV with RS&H on the 10-year, $2 billion USAF Pool 3 A-E Next vehicle) and a regional non-federal channel serving educational institutions (College of Charleston, Charleston Southern University, The Citadel), municipalities (North Charleston City Hall, Hanahan Municipal), and corporate clients (Verizon Wireless, Trumpf Medical) primarily across the Southeast. The customer base is concentrated in U.S. federal/DoD agencies, with non-federal work functioning as a regional supplement rather than a counter-cyclical offset. The firm reports 101-250 employees and is led by President Stephen Mahaffey, P.E. and CFO Robert Milanian, with no disclosed external equity, parent, or acquisition activity.
