About Landmark Construction Company, Inc. | SC. Civil, Site, & Utility Contractor

Landmark Construction Company, Inc. is an earth works company in Charleston, SC. The firm operates as a full-service heavy civil construction contractor, handling complex, large-scale projects from the ground up. It serves clients in Charleston, North Charleston, and Blythewood, SC, with offices located on North Park Blvd, Associate Dr, and North Point Blvd. The company provides sitework construction, civil construction, and removal and disposal of unsuitable or excess soils. Its capabilities include cement stabilization for building pads, soil improvement, and general site preparation. Landmark Construction has been operating for nearly six decades, maintaining a presence in the region for that duration.

The company employs advanced technology to execute its work, including Global Positioning System software, HCSS HeavyBid, Trimble Business Center, AutoCAD, Primavera P6, and Bluebeam. The estimating process involves a dual-review system where at least two estimators scrutinize every project, often mentoring newer team members. The team builds 3D models to visualize and refine plans, working closely with engineers and owners to improve site constructability and control costs. This collaborative approach extends to the field, where estimators engage directly with foremen on complex projects. The company maintains strong relationships with vendors and subcontractors, negotiating effectively to bring the right expertise to each job.

The firm offers comprehensive benefits, including medical, dental, vision, and 401(k) plans, available to all employees, including field staff, from the first full month of employment.
