CMS Corporation

What CMS Corporation does

CMS Corporation is a private, founder-controlled general construction contractor headquartered in Maumee, Ohio, founded in 1996 and re-incorporated in 2004. The firm delivers design-build and design-bid-build construction services — including new construction, renovation, fueling systems, and energy/sustainability projects — primarily for U.S. federal agencies (Air Force, Navy, Army, Coast Guard, USACE, NAVFAC, AFCEC, FBI) and secondarily for commercial clients such as FedEx, Purdue University, and IU Health. CMS has executed over 500 projects valued at $2B+ across 80+ installations worldwide, with active project backlog exceeding $400M in the Indo-Pacific region alone.

The company's core technical capabilities center on self-performed mechanical, piping, and fabrication work via its wholly owned subsidiary Customized Mechanical Solutions LLC (CMS Mechanical), which operates a 20,530-SF fabrication campus in Bargersville, Indiana, and holds API 653/510/570 certifications for fueling-system tank inspection. CMS employs BIM/VDC for mechanical systems design and the USACE 3 Phases of Control quality process, proven across 400+ projects. The firm is organized into three operating units: CMS Corporation (general construction), CMS Mechanical (POL/HVAC/process piping), and CMS K.K. (Japan-based subsidiary serving DoD clients in the Pacific). Revenue is generated through competitive bidding on federal IDIQ/MACC contract vehicles — including the $15B USAF C2E, $15B NAVFAC PDI MACC, $2.5B POL Worldwide, $4B USCG NMACC, and $600M FBI GMACC — as well as direct commercial contracts. Joint ventures with Semper Tek, Obayashi, ACCIONA, COLAS, and Jack Wayte Construction enable access to SDVOSB, EDWOSB, and small-business set-aside work that CMS cannot pursue independently after graduating from the SBA 8(a) program in 2014.

Broad incumbents

• Fluor Corporation: Global engineering, procurement, fabrication, construction, and maintenance company with significant U.S. federal/DoD portfolio including fuel systems and military infrastructure. Comparable in DoD IDIQ contracting but vastly larger and more diversified globally.
• Hensel Phelps: Large employee-owned general contractor with substantial federal/military construction practice across DoD, federal civilian, and aviation. Comparable design-build delivery model and self-perform capabilities but at meaningfully larger scale.
• AECOM: Global infrastructure consulting firm with large federal services practice covering DoD, NAVFAC, USACE, and federal civilian clients. Comparable in federal contracting scale and DoD/Indo-Pacific exposure but vastly larger and focused on professional services plus construction management.
• EMCOR Group: Largest publicly traded mechanical and electrical contractor in the U.S. with extensive federal/government work. Comparable in mechanical/HVAC/process piping capabilities, but vastly larger and more diversified across commercial and industrial end markets.
• Mortenson Construction: Large U.S. general contractor with significant federal/military and energy infrastructure portfolio. Comparable design-build delivery and self-perform approach, but operates at significantly larger scale across wind, solar, and federal markets.

Direct peers

• Sauer Construction: Mid-sized federal/heavy construction contractor with similar DoD focus including fueling systems, marine infrastructure, and military facilities. Comparable in size, mechanical/POL specialization, and IDIQ/MACC contract vehicle model.
• RQ Construction: California-based federal construction contractor of similar size, focused on DoD healthcare, military housing, and renovation projects for Navy, Air Force, and federal civilian clients. Closely comparable in revenue scale, federal concentration, and self-perform construction approach.

Others

• Obayashi Corporation: Japan-based tier-1 general contractor and CMS JV partner on $60M MCAS Iwakuni MILCON project. Comparable in design-build DoD construction capability in Japan and a current commercial partner rather than direct competitor.
• ACCIONA Construcción: Spanish-based global infrastructure major and active CMS joint venture partner on NAVFAC Pacific $15B PDI MACC. Comparable in heavy infrastructure capabilities and a current commercial partner rather than a direct competitor.

Regional players

• Black Construction Corporation: Tutor Perini subsidiary specializing in federal/MILCON construction across the Pacific, including Guam and Hawaii. Direct comparable for CMS's Guam and Pacific work, though larger and operating under different ownership structure.
