What Charter Contracting Company does

Charter Contracting Company, LLC is a privately held environmental remediation and civil construction firm founded in 1997 and headquartered in Boston, MA, operating across the Northeast United States with additional offices in Eliot, ME and Farmington, CT. The company self-performs contaminated soil and sediment management (processing over one million tons of material annually via trucking, rail, and barge), MGP and Superfund site remediation, waterways dredging and restoration, and flood risk management for federal, state, and commercial clients including the US Army Corps of Engineers, GSA, MassDCAMM, Liberty Utilities, National Grid, and Harvard University.

The business is organized into three integrated divisions: Contracting (environmental remediation, civil construction, waterway remediation), Environmental (soil/sediment management and waste-stream transportation), and Development (brownfield redevelopment and Environmental Public-Private Partnerships via the Charter Development LLC affiliate). Charter's core technical capabilities include specialized dredging equipment, Z-Boat unmanned surface vehicles for hydrographic surveying, and an EP3 model that distributes environmental liability and project risk across public and private stakeholders to unlock complex urban waterfront and brownfield redevelopment projects.

Revenue is generated through project-based professional services contracts with multi-year durations, won primarily through competitive bidding and direct enterprise sales to government agencies and commercial clients. The company carries no disclosed external funding and operates without a parent organization. Charter has been ranked on the ENR Top 200 Environmental Firms list for 18 consecutive years (#116 in 2022, jumping 12 spots year-over-year), and has received multiple AGC Build America Awards, EBC honors, and Boston Globe Top Places to Work recognition.
