What Landmark Construction Company, Inc. does

Landmark Construction Company, Inc. is a privately held heavy civil site work contractor founded in 1965 and headquartered in Charleston, South Carolina. The company self-performs four integrated service lines: site work (clearing, grading, earthwork, soil stabilization, building pads), underground utilities (water, sanitary sewer, storm drainage, dry utilities), concrete construction (civil, structural CIP, elevated, specialty), and industrial maintenance (structural, mechanical, electrical, emergency response). It also operates a construction materials business (Sandworks plus dirt pits) supplying sand, fill dirt, and topsoil to its own projects and external concrete plants and masonry contractors. Landmark serves enterprise and institutional clients across the Southeast — industrial and manufacturing developers, automotive and EV OEMs, energy and chemical operators, commercial developers, school districts, and government entities — functioning as either prime contractor or subcontractor on competitively bid projects.

The company leverages a modern construction technology stack centered on Trimble GPS machine control, Trimble Earthworks semi-autonomous grade control platforms, in-house 3D site modeling, drone-based photogrammetry, and standard project management tools (Primavera P6, Bluebeam, AutoCAD, Trimble Business Center). A fleet of more than 165 pieces of heavy equipment enables execution of multi-million cubic yard earthmoving campaigns. Landmark's go-to-market is enterprise field sales driven by direct engagement with general contractors, developers, engineers, and public agencies; pricing is project-specific through competitive bidding, with multi-year master contracts on industrial maintenance engagements. The company is family-controlled by the Mixson family, led by President Rick Mixson, and operates from Charleston (HQ), North Charleston, and a newly opened Midlands office in Blythewood, SC, with stated service reach into Georgia.

Recent strategic positioning has centered on the Scout Motors EV manufacturing facility in Blythewood ("Project Connect") — described as the largest earthmoving operation in the Southeast at 24.2 million cubic yards across 1,363 acres — alongside ongoing marquee engagements for Volvo Cars and Mercedes-Benz Vans, repeat industrial maintenance for Bosch, DuPont, BP, Chevron, and others, and a 1-million-man-hour zero-recordable safety record. Management was deepened in 2024 with the appointment of a CFO, promotion of a Chief Strategy Officer, and a broad internal succession cycle, while externally the company is publicly positioning itself as a technology-forward heavy civil firm via CONEXPO-CON/AGG 2026 case studies on autonomous equipment and AI-driven fleet management.

Broad incumbents

• Brasfield & Gorrie: One of the largest Southeast-based general contractors with civil, industrial, and commercial divisions operating across Landmark's geographic footprint. Broad incumbent competing for the same industrial/EV plant packages at a larger balance-sheet scale.
• Kiewit Corporation: National heavy civil and infrastructure contractor with deep experience in massive earthwork and industrial site development. Actively pursuing EV/battery mega-projects in the Southeast, representing the upper-tier competitor for landmark-class industrial packages.
• Haskell: Jacksonville-based Design-Build firm with industrial, civil, and architectural services across the Southeast. Larger-scale incumbent operating in related industrial/manufacturing construction categories with overlapping client profiles.
• Granger Construction / Granite Construction (Industrial Services): Large publicly-traded heavy civil contractor with materials, site work, and infrastructure operations across multiple U.S. regions. Comparable materials-plus-site-work vertical model and potential entrant on Southeast industrial mega-projects.

Direct peers

• C.W. Matthews Contracting Co. Georgia-headquartered heavy civil contractor specializing in earthwork, grading, utility installation, and transportation infrastructure. Direct regional competitor for the same industrial, manufacturing, and transportation project pipeline Landmark pursues.
• Evans General Contractors: South Carolina-based general contractor serving industrial, commercial, and institutional clients across the Southeast. While broader, they are a listed repeat customer and direct regional competitor for the same industrial/manufacturing site packages.
• Thalle Construction: Mid-Atlantic/Southeast heavy civil site work contractor performing mass grading, utilities, and infrastructure for industrial and commercial developments. Directly comparable in project profiles and blue-chip industrial client base.
• Crowder Constructors: Charlotte-area heavy civil contractor performing site work, utilities, and infrastructure for industrial and commercial clients across the Carolinas and Georgia. Highly comparable in scope and regional focus to Landmark's civil and underground utility divisions.
• Barnhill Contracting Company: North Carolina-based heavy civil and site preparation contractor with extensive grading, utility, and infrastructure work across the Carolinas. Closest direct peer to Landmark given overlapping Southeast geography and nearly identical service mix (site work, utilities, concrete).

Regional players

• Beverly-Grant Construction: Mid-South heavy civil and site preparation contractor with comparable grading, utility, and concrete capabilities. Slightly different geographic center (Tennessee/Kentucky) but competes for the same tier of industrial mega-project packages.
