Jansen Construction Company

What Jansen Construction Company does

Jensen Construction Company is a privately held, fourth-generation family-owned heavy civil contractor founded in 1912 and headquartered in Des Moines, Iowa. The firm operates as the oldest subsidiary of The Rasmussen Group, a diversified conglomerate. Its core competency is the design and construction of large, technically complex bridge structures that other general contractors prefer to decline, including 17 bridges completed over the Missouri River and projects delivered across 11 U.S. states. The company also performs heavy highway construction, marine work, railroad construction, and wind tower foundation work as part of its broader civil infrastructure portfolio. Contract values range from approximately $14 million for municipal crossings to $92.9 million for the Lake Lewisville Toll Bridge, with the largest clients being state Departments of Transportation (Texas, Tennessee, South Dakota) and municipal agencies.

The company's go-to-market is exclusively enterprise field sales directed at public-sector infrastructure buyers, with projects secured through competitive bidding processes. Pricing is project-based with unit pricing mechanics and multi-year billing cadences aligned to construction milestones. The firm maintains a regional office in Sand Springs (Tulsa area), Oklahoma to serve South Central U.S. infrastructure demand. Marketing channels are limited to a corporate website hosted on the Rasmussen Group platform and organic social media presence (Facebook, Instagram), consistent with a relationship-driven, bid-driven business development model rather than demand generation.

Jensen Construction Company generates revenue through one-time construction contracts awarded via competitive government procurement. There are no subscription, licensing, or recurring revenue streams; each project represents a discrete, multi-year revenue event tied to physical construction execution. The business is highly dependent on public infrastructure spending cycles, state and federal transportation funding programs, and the firm's continued ability to win competitive bids against larger national bridge contractors. The reported employee count of 1–10 is inconsistent with project scale and likely reflects corporate/management headcount only, with project-site labor presumably sourced through subcontracting or seasonal hiring arrangements.

• Flatiron Constructors: Subsidiary of HOCHTIEF delivering large bridge, highway, and rail projects across the US — broader portfolio than Jensen but direct head-to-head competition on complex bridge bids.
• Lane Construction: Webuild subsidiary executing heavy civil and transportation infrastructure including major bridges — larger and broader but directly competes on complex bridge work.
• Kiewit Infrastructure: One of North America's largest employee-owned heavy civil contractors, executing the largest bridge and infrastructure projects — competing for the upper end of Jensen's addressable market.
• Granite Construction: Large publicly traded heavy civil contractor with extensive bridge and transportation infrastructure portfolio — broader reach but overlapping heavily with Jensen's bridge and heavy highway work.
