Carone and Company Inc.

What Carone and Company Inc. does

Carone and Company Inc. is a family-owned Bay Area civil construction contractor, with its current corporate form established in 1999 under CEO Lloyd Carone though the Carone family business traces to 1956. The company operates as both a general contractor and subcontractor, providing a unified "one-stop civil shop" of site work services—demolition, excavation and grading, utilities installation (including trenchless pipe bursting and directional boring), shoring, paving, and material recycling—primarily for public agencies, private commercial developers, and industrial clients across Northern California.

The company is differentiated by its vertically integrated materials supply through its wholly-owned subsidiary Diablo Valley Rock, a 13-acre concrete and asphalt recycling plant in Martinez, CA, which processes aggregate base materials for both internal projects and public sale. Carone maintains a fleet of 80+ pieces of heavy equipment fitted with modern precision technology including laser-guided excavator tracking, GPS-enabled grade controls, and electronic sonar finish matt grade control. The company is a union signatory contractor (Operating Engineers, Laborers, and Teamsters) with approximately 75 employees, including field foremen holding 300+ years of combined experience.

Revenue is generated through project-based contracts obtained via competitive bidding on public works and private commercial work, supplemented by long-term repeat business from Bay Area general contractor relationships spanning up to 50 years. Pricing is project-specific and not publicly disclosed. Notable customers include Costco, West Bay Builders, Sundt Construction, KB Homes, St. Mary's College, multiple municipal and state government agencies, and oil refineries. Annual revenue exceeds $20 million, down from a $22 million peak; the firm previously scaled from 25 to 125 employees between 1989 and 1997 but currently operates at a smaller scale following the 1999 cooperative three-way family split.

Scale indicators6 records

Expansion highlights3 records

Regional players

• Stacy and Witbeck: California and Western U.S. heavy civil contractor focused on rail, transit, and transportation infrastructure. Comparable in self-perform earthwork and grading capability, with a heavier tilt toward rail work than Carone's commercial/industrial mix.

Direct peers

• Bay Counties Site Development: Northern California site preparation and earthwork contractor. Comparable regional peer in mass grading, excavation, and site work for residential and commercial developers, though smaller and more limited in scope than Carone.
• Teichert Construction: Sacramento-based, family-owned heavy civil and site work contractor operating across Northern California. Directly comparable to Carone in earthwork, grading, paving, utilities, and concrete services, with a similar regional footprint and union workforce model.
• DeSilva Gates Construction: Bay Area-based site work and heavy civil contractor specializing in excavation, grading, paving, and underground utilities. Closely comparable to Carone in scope, customer base (Bay Area GCs and public agencies), and self-perform heavy equipment model.
• O.C. Jones & Sons: Berkeley-based Bay Area site work contractor providing excavation, grading, paving, and utilities. Comparable regional footprint, similar customer mix of public agencies and private developers, and overlapping self-perform heavy equipment capability.
• McGuire and Hester: Oakland-based site work, underground utilities, and paving contractor serving the Bay Area. Directly comparable to Carone in scope, regional focus, customer base, and fleet-driven execution model.

Broad incumbents

• Granite Construction: Large publicly traded California-headquartered heavy civil contractor with extensive site work, paving, and materials operations. Comparable service lines but much larger scale, broader geography, and vertically integrated aggregate reserves vs. Carone's regional one-stop shop.
• Sundt Construction: Large employee-owned general contractor with significant California heavy civil and site work operations. Comparable as a partner/subcontractor relationship (Carone has worked with Sundt) and overlapping earthwork, paving, and utilities scope.
• Sukut Construction: California-based heavy civil and grading contractor with significant earthwork, site preparation, and quarry/recycling operations. Comparable to Carone's Diablo Valley Rock-style vertical integration but at materially larger scale.

Others

• Dokken Engineering: California-based infrastructure design and construction management firm. Adjacent rather than competitive — participates in many of the same Bay Area public infrastructure projects (bridge, roadway, water) as a designer/CM rather than self-perform site work contractor.
