What Belair Sitework Services does

Belair Sitework Services is a privately held, family-owned U.S. construction services company founded in 1953 by Henry A. Murlowski and currently controlled by the second-generation Murlowski ownership group. The company delivers integrated sitework and prime contracting services through six business units: Earthwork, Environmental, Foundation/Concrete, Site Demolition, Utilities, and Specialty. Service delivery is supported by modern field technologies including GPS machine control, drones, AGTEK takeoff/modeling software, advanced laser technology, and a proprietary LEAN management practice intended to eliminate waste on complex projects. The firm is headquartered in New Brighton, Minnesota, and operates regional offices in Commerce City, Colorado; Captiva Island, Florida; and Plano, Texas, with traveling crews executing projects nationally.

Belair generates revenue through project-based competitive bidding and direct contracts with general contractors, private owners/developers, and government/public agencies. Its customer base spans at least eight verticals including healthcare (Health One/Presbyterian St. Luke's, Exempla Saint Joseph Hospital), energy (Florida Power and Light DeSoto Solar, Magellan Midstream Partners), federal government (US Customs and Border Patrol, Department of Energy/NREL), municipal (City of Robbinsdale), sports/entertainment (Minnesota Twins Target Field), aviation (Embraer), and waste management (Waste Connections). Notable references include a $113 million, 80,000 SF hospital addition with substantial underground utility work and an 800,000 SF, 350-bed hospital utility upgrade. The go-to-motion is enterprise field sales via direct engagement and an in-house Estimating Department ([email protected]), supplemented by repeat business from public and private owners.

The company carries 251-500 employees, with a workforce described as long-tenured across both field labor and senior management. Belair differentiates through an integrated multi-discipline service offering, a safety culture anchored by two full-time safety professionals and recognized by the National Safety Excellence Award and AGC CHASE White Level participation, and substantial heavy equipment inventory accumulated over decades. No AI/ML capability is disclosed; the technology stack remains conventional for the heavy civil/specialty construction sector. The firm operates without institutional ownership, public listing, or disclosed external funding, and its strategy is oriented around safety-critical multi-division project execution rather than rapid scale or geographic expansion beyond its current four-state footprint plus traveling project teams.
