DeMaria

What DeMaria does

DeMaria Building Company is a privately held, Michigan-based construction management and general contracting firm founded in 1969 in Detroit. It delivers projects through three primary methods — Construction Management, Design-Build, and General Contracting — supported by an in-house pre-construction service covering project evaluation, benchmarking, risk analysis, life cycle analysis, value engineering, bid packaging, design assist, and BIM coordination. A wholly-owned subsidiary, DSP Constructors, provides self-perform capabilities in concrete, earthwork, selective demolition, and interior carpentry, giving the firm direct control over critical-path trades. The CLIMB Internship Program and multi-decade tenures of senior leadership (e.g., CFO Rick Flynn at 26 years, EVP Mike Joseph at nearly 30 years) support workforce development.

The firm operates three offices across Michigan — Detroit (headquarters), Novi, and Okemos (Lansing area) — with announced plans to open a Tampa, Florida office. Its project base spans healthcare (Corewell Health $39M Service Center, Henry Ford Health, Detroit Wayne Integrated Health Network), higher education (University of Michigan, Michigan State University), energy (DTE Energy power plants and O&M expansions), federal and municipal government (U.S. Department of Veterans Affairs medical centers, City of Detroit), industrial and automotive (Ford, GM, Daimler Chrysler), commercial and hospitality (Marriott, Ford HQ Café), and transportation. Contract sizes range from roughly $400K commercial fit-outs to $40M+ healthcare facility renovations, with ICRA-certified healthcare teams and differentiated credentials on safely executing work in active operational environments. Technology adoption centers on Procore for project documentation, TradeTapp for trade-contractor pre-qualification, and Building Connected for bid management.

DeMaria is family-owned under the DeMaria family (Joseph A. DeMaria Jr. as CEO, Tony DeMaria as President) with shared-ownership principal status extended in September 2022 to Darren Murray (EVP Operations / DSP), Mike Joseph (EVP Estimating), Rick Flynn (CFO), and Aaron Tassell (EVP). Revenue is project-based and not publicly disclosed. The business model depends on competitive bidding and qualifications-based selection, with multi-year contract cadence and relationship-driven repeat business from institutional clients; pricing is not standardized. Marketing leverages workplace awards (19 consecutive Best and Brightest wins; Crain's Cool Places to Work 2020–2022), trade publication features, community programs (DeMaria in Action), and sustainability credentials (US Green Building Council membership, WHC Conservation Certification, LEED-targeted delivery).
