Marine Liability Coverage

When bridge construction occurs over navigable waters, marine liability coverage becomes essential. This specialized coverage addresses risks that standard general liability policies exclude.

                Navigation Risk: Bridge construction can create navigation hazards for commercial and recreational vessels. Marine liability coverage protects against claims for vessel damage, cargo loss, and personal injury resulting from construction activities.
            

Key marine liability coverage elements include:

Vessel collision coverage: Protection against claims from vessels striking construction equipment or partially completed structures
Navigation interference: Coverage for business interruption claims from shipping companies
Marine environmental liability: Protection against pollution claims in waterways
Wreck removal coverage: Costs to remove sunken equipment or debris
Longshoremen and harbor workers coverage: Specialized workers' compensation for marine workers

Case Study: Bay Bridge Replacement Project

During the San Francisco-Oakland Bay Bridge replacement, a barge carrying bridge segments collided with the existing bridge due to navigation errors. The incident resulted in $15 million in damages and delays. Marine liability coverage was critical in addressing claims from both the collision damage and the resulting navigation disruptions.

Professional Liability for Design-Build Projects

The increasing prevalence of design-build project delivery in bridge construction has created new professional liability exposures. When contractors assume design responsibility, they face risks traditionally borne by architects and engineers.

Professional liability coverage for bridge contractors should include:

Design errors and omissions: Coverage for mistakes in structural design or engineering calculations
Technology errors: Protection against errors in computer modeling or simulation software
Project management errors: Coverage for coordination and scheduling mistakes
Third-party claims: Protection against claims from end users affected by design defects

Frequently Asked Questions About Bridge Construction Insurance

Do I need marine liability coverage for all bridge construction projects?

Marine liability coverage is required for any bridge construction over navigable waters or where construction activities could impact marine traffic. Even small waterways may require marine coverage if they're designated as navigable. The Coast Guard typically makes this determination during the permit process.

How does design-build delivery affect my insurance requirements?

Design-build projects require professional liability coverage in addition to standard construction insurance. You'll need coverage for design errors, technology failures, and coordination mistakes. Professional liability limits typically range from $2-10 million depending on project complexity.

What happens if load testing reveals structural problems?

Load testing coverage should include protection for test failures, remedial work costs, and delay expenses. Some policies exclude testing failures, so ensure your coverage specifically includes load testing and proof loading operations. This coverage often requires separate limits from standard property coverage.

Are environmental permits covered under standard pollution liability?

Standard pollution liability may not cover permit violations. Bridge projects often require specialized environmental coverage including permit defense, fine and penalty coverage, and natural resource damage protection. Review your environmental coverage carefully for permit-specific language.

How do I determine workers' compensation requirements for over-water work?

Work over navigable waters may require Jones Act coverage or Longshore and Harbor Workers' Act coverage instead of standard workers' compensation. The determination depends on the specific location and nature of the work. Consult with maritime law specialists to determine proper coverage.

What is 'delay in opening' coverage and do I need it?

Delay in opening coverage protects against lost revenue and additional expenses when bridge opening is delayed beyond the scheduled completion date. This coverage is particularly important for toll bridges or projects with significant liquidated damages. Coverage typically ranges from 6-24 months of protection.

How do I handle insurance for multi-year bridge projects?

Multi-year projects require careful coordination of annual policy renewals and may benefit from multi-year policy structures. Consider project-specific policies rather than annual programs to ensure consistent coverage and avoid gaps. Builder's risk policies are often structured for the project duration.
