What Concrete General does

Concrete General, Inc. is a privately held, family-owned heavy highway civil construction contractor headquartered in Gaithersburg, Maryland. Founded in 1972 by Carl Miller as a concrete flatwork contractor, the company has expanded over three generations into a full-service prime contractor delivering bridges, roadways, interchanges, retaining walls, box culverts, storm drainage, emergency repairs, and railroad infrastructure across Maryland and parts of Virginia. Its service catalog spans 20 distinct offerings covering excavation and grading, asphalt and concrete paving, bridge construction and maintenance, design-build, project management, surveying, safety, and maintenance of traffic.

The company operates as a sales-led prime contractor through three primary project delivery models — Design-Build, Bid-Build, and Construction Manager at Risk (CMAR) — and also accepts negotiated contracts. Customers are exclusively public-sector transportation agencies, led by the Maryland Department of Transportation State Highway Administration (MDOT SHA), Montgomery County Department of Transportation (MCDOT), the City of Baltimore, and the Maryland Transportation Authority (MDTA). Project acquisition is bid-driven through competitive procurement; concrete general maintains a vendor registration and bid-document portal on its corporate website to manage subcontractor and supplier participation.

The underlying technical capability rests on a fleet of heavy construction equipment (bulldozers and specialized machinery) plus an in-house workforce of 350+ skilled personnel enabling self-performed civil work. Revenue is project-based and episodic, with single contracts ranging from under $7 million to approximately $100 million (the I-270 Innovative Congestion Management Progressive Design-Build). The company is recognized through more than two dozen industry awards since 1999, including a 2017 Roads and Bridges Magazine ranking as the #3 bridge project in North America, multiple Maryland Quality Initiative (MDQI) awards, and American Concrete Institute (ACI) Excellence in Concrete Awards.
