What Structures does

Structures Inc. is a privately held heavy civil construction contractor founded in 1998 and headquartered in Englewood, Colorado. The company designs, builds, and rehabilitates bridges, retaining walls, and box culverts, and executes supporting structural concrete, pile driving, hydrodemolition, and emergency repair work for public, private, railroad, industrial, and commercial clients across Colorado and the Denver metro area. Typical projects range from $2 million to $30 million in value.

The company's technical foundation is its owned pile-driving equipment fleet — including cranes, leads, spotters, excavators, and both diesel and hydraulic vibratory hammers — combined with in-house volumetric concrete mixing expertise using proprietary additive and admixture proportioning. Service delivery spans Design-Build, Heavy Structural Concrete, Structural Rehabilitation, Emergency Repair, Pile Driving, Hydrodemolition, and Bridge Access Equipment, organized around four primary project categories (bridges, box culverts, retaining walls, railroads) plus miscellaneous structural work. PE-credentialed leadership and a GSP-certified safety function support technically demanding public-sector scopes, such as the concrete shear walls delivered for the Douglas County Justice Center expansion.

Structures Inc. generates revenue through fixed-price, project-based contracts bid via a consultative enterprise field-sales motion — direct engagement through phone, email, and website inquiry, with a dedicated estimating line — targeting government agencies as the primary vertical and industrial, commercial, railroad, and private development clients as secondary segments. Pricing is project-specific and quote-based; no standard tiers or recurring subscription revenue exists. The company operates with no disclosed external investors, parent company, M&A history, or funding rounds, consistent with a founder/management-owned regional construction firm.

• Ames Construction: Heavy civil and transportation contractor delivering bridges, dams, and rail projects nationwide. Directly comparable on bridge construction, heavy structural concrete, and self-perform foundation work.

• PCL Construction: Diversified North American contractor with a sizable civil infrastructure division delivering bridges and transportation projects across the western US and Canada, often competing for the same DOT work.
• Sterling Construction Company: Heavy civil construction company delivering transportation, water, and specialty infrastructure projects across the US. Overlaps with Structures Inc. on structural concrete, bridge, and box culvert scope.

Others
