EAST COAST MARINE CONSTRUCTION CONTRACTORS
One accountable subcontractor for complex, in-water infrastructure.
Coastal Marine Construction self-performs the full scope of marine and heavy civil work along the East Coast, from pile driving and diving to concrete, rebar, and structural steel.
THE FULL SCOPE.
SELF-PERFORMED.
Coastal Marine Construction self-performs the full scope of marine and heavy civil work along the East Coast, from pile driving and diving to concrete, rebar, and structural steel.
General contractors get one accountable subcontractor for complex, in-water infrastructure instead of coordinating multiple specialty subs.
PLANNED
AROUND THE WATER.
Marine construction projects rarely stay within a single trade. A bridge repair, wharf expansion, or shoreline stabilization job can call for pile driving, underwater welding, concrete work, and structural steel on the same schedule. Most marine contractors specialize narrowly and sub out the rest, which adds coordination risk for the general contractor managing the package. Coastal Marine Construction was built differently. We self-perform nearly the entire marine scope using our own fleet of barges, cranes, tugboats, and marine equipment, which means fewer subs, fewer schedule dependencies, and one point of accountability.
Our process starts with estimating and pre-construction planning, where our team asseses the site conditions, environmental requirements, and technical challenges before pricing the work. From there, we move into execution with the same core crew, coordinated internally rather than handed off between separate subcontractors. That continuity is what keeps weather- and tide-dependent projects on schedule. We also stay hands-on with owners and engineers throughout construction, solving problems on site as they come up instead of escalating or hiding behind scope exclusions.
CLIENT TESTIMONIALS
FREQUENTLY ASKED QUESTIONS
What does a marine construction contractor do?
A marine construction contractor builds and repairs infrastructure in or near water, including piers, wharfs, seawalls, and pilings. Coastal Marine Construction self-performs this work, from pile driving and diving to concrete and structural steel, rather than subcontracting pieces of it out.
What is self-performed marine construction?
Self-performed marine construction means the contractor completes the work with its own crews and equipment instead of hiring subcontractors for individual trades. Coastal Marine Construction self-performs pile driving, diving, demolition, concrete, rebar, gunite, structural steel, and blasting and painting.
Who hires a marine construction subcontractor?
General contractors, municipalities, government agencies, and transportation departments hire marine construction subcontractors when a project requires in-water work they don’t have the in-house capability to perform.
What types of marine construction projects does Coastal Marine handle?
Coastal Marine Construction handles pile driving, sheet piles and cofferdams, piers and wharfs, timber pier construction, revetment, riprap, and deep water construction, along with diving, demolition, and marine salvage.
What makes marine construction different from land-based construction?
Marine construction involves working in or adjacent to water, which adds tidal, weather, and environmental considerations that don’t apply to land-based projects. It often requires specialized equipment like barges, cranes, and diving crews.
Where does Coastal Marine Construction operate?
Coastal Marine Construction operates from three locations in Massachusetts (Stoughton, Vineyard Haven, and New Bedford) and works on projects throughout the East Coast.
