Colasanti Group

What Colasanti Group does

Colasanti Group (legal entity The Colasanti Companies) is a privately held, family-owned construction firm founded in 1955 and headquartered in Macomb, Michigan, with a regional headquarters in Florida. The company operates as a premier general contractor and construction manager specializing in cast-in-place concrete, complemented by self-perform concrete crews capable of complex custom formwork. Two wholly owned subsidiaries, Colasanti Construction Services, Inc. (Midwest) and Colasanti South, Inc. (Southeast), deliver services across 35 states in the Midwest and Southeast United States.

The service platform spans full-service construction management and general contracting (GC/CM), self-perform concrete with complex custom formwork, field engineering, pre-construction, operations management, building information modeling (BIM), quality assurance and control, and a proprietary "Colasanti Safe" safety program. Technology is conventional construction-tech rather than AI-native: BIM-based 3D modeling, digital field engineering (total-station workflows), and a BuildingConnected-based subcontractor portal. Key differentiators cited are self-perform execution, BIM-enabled workflow, and rigorous in-house QA/QC and safety processes (the latter reinforced by voluntary MIOSHA partnerships on flagship projects).

The business model is project-based B2B construction services: revenue is generated through fixed-price or GMP contracts bid as a prime contractor via dedicated estimating departments for concrete (split South/Midwest) and GC/CM services. Pricing is quote-based and not publicly disclosed. Customers are construction project owners and developers across the Midwest and Southeast, served through a horizontal segmentation approach. Go-to-market is sales-led enterprise bidding on large construction projects, with the recent addition (2024) of a dedicated VP of Business Development formalizing pipeline development.
