What Heavy Constructors does
Heavy Constructors, Inc. is a privately held, family-owned full-service construction firm founded in 1919 by the Gustafson family and headquartered at 4101 Deadwood Avenue North, Rapid City, South Dakota. The company operates three wholly owned divisions: Heavy Constructors (civil construction including grading, structures, concrete paving, bridges, box culverts, and utility work for federal, state, and municipal clients), Gustafson Builders (commercial and residential building construction delivered via design-build, integrated, and Construction Manager at Risk with Guaranteed Maximum Price methods), and Excavating Specialists (trenchless boring, cable plowing, fiber jetting, and aerial lining for telecommunications and utility clients in Western South Dakota). A Layton-Gustafson Joint Venture extends the firm's capacity to bid and deliver large healthcare and institutional projects alongside Layton Construction.
The business model is project-based and relationship-driven, with revenue generated through hard-bid general contracting, CMAR/GMP engagements, design-build, and subcontracting to other prime contractors. Pricing is set per project scope (no standardized price list), with individual project values referenced across the portfolio ranging from approximately $269,887 to $31,973,000. The company self-performs the majority of its work using owned equipment and an on-site concrete batch plant, and it markets primarily through its website, Facebook presence, civic engagement, and referral networks across western South Dakota and the broader Midwest. Notable customers include the South Dakota DOT, the City of Rapid City, the Corps of Engineers / Pine Ridge Indian Health Services, Rapid City Regional Health, the Rapid City School District, Hilton Garden Inn, Safeway, and Coca-Cola, with multiple AGC and industry trade awards (including AGC Build America) reinforcing its regional reputation.
