What SJ Hamill Construction does
SJ Hamill Construction, LLC is a private marine and heavy civil construction contractor headquartered at 2008 Cherry Hill Lane in North Charleston, South Carolina. The company operates as a subsidiary of Heico Holding, Inc., a diversified parent group. Founded in 2015 and licensed to operate in seven states across the Southeast and Mid-Atlantic (South Carolina, North Carolina, Georgia, Florida, Alabama, Maryland, and Virginia), SJ Hamill delivers an integrated portfolio of five core service lines: Marine Construction, Heavy Civil Construction, Shoreline Stabilization, Pile Driving and Shoring, and Mechanical Dredging. Its technical capabilities include large diameter marine piling installation, driven battered piles, sheet pile cells and walls, cofferdam construction, mechanical and bucket dredging, and shoreline protection systems including groins, revetments, and rip rap placement.
The company self-performs the vast majority of project scope — exceeding 95-100% on multiple recent engagements — indicating ownership of specialized marine construction assets and in-house operational expertise drawn from leadership with over 100 years of collective heavy civil experience. SJ Hamill's revenue model is entirely project-based, with contracts sourced through direct enterprise sales to government agencies, port authorities, municipalities, and industrial clients. Marquee engagements include work for the South Carolina Ports Authority (Hugh K. Leatherman Terminal site preparation and Wando-Welch Terminal ship-to-shore crane foundations), Vulcan Materials (Cooper River Terminal), Nexans (Project Osprey cable-laying wharf), City of Savannah (Bilbo Canal widening), Clemson University Restoration Institute, and T&T Salvage (Golden Ray vessel salvage breasting dolphins). The company partners with project shareholders early in the engagement to identify cost and schedule savings, emphasizing fast-tracked delivery on complex work, including completion of the Fripp Island shoreline protection project in under half the contracted 120-day timeline.
