What Bommarito Construction does

Bommarito Construction is a privately held, family-owned site development and utility construction contractor founded in 1997 by Joseph W. Bommarito and headquartered in Fenton, Missouri. The company operates as part of the JWBCO (JW Bommarito Companies) family of companies alongside the affiliated American Fire brand, and serves the greater St. Louis metropolitan area as a regional specialty subcontractor. Its primary customers are general contractors and commercial, residential, and institutional developers requiring full preconstruction site development, including earthwork, storm and sanitary sewers, water lines, concrete flatwork, MEP excavation, and BMP stormwater solutions.

The company's service portfolio is delivered under fixed-price or cost-plus contracts quoted per project. Core service lines — storm sewers, sanitary sewers, water lines, earthwork, and concrete flatwork — can be paired with a value-based engineering consultation that collaborates with design engineers on cost-effective plan alternatives. The firm operates a specialty division, BMP Stormwater Solutions, focused on the maintenance, repair, and reconstruction of stormwater systems, providing recurring-revenue aftermarket services. Operational technology is limited to industrial tooling: Trimble GPS machine control for precision earthwork, drone surveying for real-time progress monitoring, and in-house takeoff services for estimation. No public pricing, SaaS product, or API exists; all engagement is direct B2B project work.

Bommarito monetizes exclusively through project-based construction services. Distribution is direct enterprise sales to general contractors and developers, supported by membership in AGC, AGC Missouri Chapter, and the Site Improvement Association, and a social media presence (Facebook, Instagram, LinkedIn). The company holds Missouri American Water approved contractor status, a regulatory credential required for water infrastructure installation, and markets a coordinated single-provider workflow as its principal differentiator versus single-discipline subcontractors.
