Quick answer
New York dock builders, pier builders and seawall and bulkhead contractors work at the line between land and water, and their insurance has to cover both sides. The core program is workers' comp with a USL&H endorsement (dock and pier construction is classic Longshore exposure), Maritime Employers Liability if crews live or work aboard a barge, marine or contractor's general liability that does not exclude your work boats, hull and P&I for barges and push boats, contractor's equipment for cranes and hammers, and builders risk for the structure. Homeowners and marinas often ask for proof of all of it. We build dock builder programs for residential and commercial work across New York.

Fastest way to a quote: email your current policies (workers' comp with any USL&H endorsement, GL, hull and P&I), five years of loss runs, payroll split between land-side work and work on or over the water, your vessel and equipment schedules, a project list and the insurance section of a typical contract to adolfo@nextguardinsurance.com. Marine underwriters need the full picture, and one complete submission moves faster than ten phone calls.
Please send your account to one broker. The marine market is small; when several brokers submit the same account to the same underwriters, the account gets blocked and quotes slow down.
| Exposure | Why it matters | Coverage that responds |
|---|---|---|
| Crew on the pier or in the water | Dock and pier construction meets the Longshore Act's status and situs tests | Comp with USL&H endorsement |
| Crew assigned to a barge | A worker with a substantial connection to a vessel may be a Jones Act seaman | Maritime Employers Liability |
| Barge and push boat | Physical damage, collision, wreck removal and third-party injury from vessel operations | Hull & P&I |
| Damage to a client's property | Boats, existing docks, utilities, neighboring bulkheads, the shoreline | Marine general liability |
| Crane or hammer overboard | Equipment lost or damaged on a barge or at the water's edge | Contractor's equipment written for marine use |
| Storm during construction | A half-built bulkhead or pier damaged by a storm, surge or ice | Builders risk |
| Collapse or settlement after completion | A failed bulkhead can damage the property behind it years later | Completed operations under GL |
We found no separate dock builder class in the New York Classification Digest. Dock and pier work is assigned by the actual operations. Common New York classes and their NYCIRB loss costs per $100 of payroll, effective October 1, 2026:
| Class | Work | Loss cost |
|---|---|---|
| 6003 | Pile driving, NOC | $4.519 |
| 6005 | Breakwater or jetty construction | $2.986 |
| 9534 | Mobile crane and hoisting service | $3.864 |
| 5057 | Iron or steel erection, NOC | $5.722 |
| 5403 | Carpentry, NOC | $11.232 |
| 5213 | Concrete construction, NOC | $16.455 |
The USL&H factor is added on top for payroll exposed to the federal act. Getting your classes and payroll split right is the biggest lever on price, so we review them before we submit.
Residential dock builders get caught here. A small crew doing homeowner docks often buys a standard contractor policy with state comp only. If a worker is hurt on the dock or falls from the barge, the Longshore Act can still apply. A homeowner's or marina's certificate request is usually the first sign the program is wrong; fix it before the claim.
The full marine program is laid out on our marine contractors insurance page.

A dock builder typically needs workers' comp with a USL&H endorsement, Maritime Employers Liability if crews work aboard a barge, general liability that does not exclude the contractor's watercraft (often marine general liability), hull and P&I for barges and work boats, contractor's equipment coverage, builders risk and completed operations coverage.
Usually yes. Building and repairing docks and piers is harbor work under the Longshore Act, and injuries on the water or on an adjoining pier or wharf meet the situs test. A standard New York comp policy without the USL&H endorsement can leave that exposure uninsured.
Often yes. Even small residential dock jobs can bring Longshore exposure for the crew and watercraft exposure for any barge or boat. A standard CGL excludes owned watercraft, so a residential dock builder using a barge usually needs hull and P&I and liability written for marine operations.
It can be. Coverage depends on the status and situs tests: whether the work is maritime employment and whether the injury happens on navigable water or an adjoining area. Bulkhead work from the water or along a pier usually qualifies; work entirely on upland property may not.
There is no separate dock builder class in New York. Payroll is classified by the work done, often pile driving (6003), carpentry, concrete or steel erection. For policies effective October 1, 2026, NYCIRB's loss cost for pile driving NOC is $4.519 per $100 of payroll, before the insurer's multiplier, experience mod and any USL&H factor.
Builders risk can cover the structure while under construction, but many forms exclude or limit property in or over water. Make sure the policy is written for marine construction and check the storm, flood and ice provisions.
Yes. We write dock builders across New York State, including Long Island, Westchester, the five boroughs and the Hudson Valley.
