Consigli Construction Co., Inc.

What Consigli Construction Co., Inc. does

Consigli Construction Co., Inc. is a fifth-generation, 100% employee-owned (ESOP since 2018) construction management and general contracting firm headquartered in Milford, Massachusetts, founded in 1905. The company delivers institutional, healthcare, life sciences, advanced technology, mission critical, higher-education, federal, and landmark-restoration projects across 15 regional offices spanning Maine to the Caribbean, with annual construction volume of approximately $4.4 billion and 2,600+ employees, including 900+ skilled tradespeople in the Riggs self-perform division.

The service stack is built around an integrated approach rather than a single product: Virtual Design & Construction (BIM, 3D coordination, VR/AR, Matterport reality capture); Lean Project Delivery (Pull Planning, Last Planner System, Target Value Design); mass timber design-assist and installation (15+ years, 35+ projects); dedicated prefabrication (used on 100+ projects); the Arch Energy decarbonization line with Energy-as-a-Service and Thermal Energy Purchase Agreement financing; and self-perform trades spanning sitework, concrete, carpentry, masonry, and demolition. These capabilities are deployed through vertical market leaders in Life Sciences, Advanced Technology, Mission Critical, Healthcare, and Academic markets, supported by named leadership at the director level for each specialty.

Revenue is generated through project-based professional services fees on construction value delivered, with project sizes ranging from under $2.5 million (Special Projects Group) to multi-billion-dollar multi-year programs. Distribution is direct, via regional office business development targeting enterprise and institutional buyers; the only channel partner is the J. Benton Construction relationship for Caribbean operations. Customers include Mass General Brigham, Memorial Sloan Kettering, NYU Langone, Pfizer, Biogen, Autodesk, MIT, Harvard, the Smithsonian, and federal agencies including the Architect of the Capitol and the National Park Service. The 2024 acquisition of substantial Lendlease NY/NJ operations (400+ employees, $1.8B of work) materially expanded the NYC metro footprint.
