Catastrophic loss coverage disputes arise when an event of significant magnitude — an engineering failure, a natural disaster compounded by design defects, or a mass incident involving structural collapse — produces claims that exhaust primary coverage layers and implicate excess and reinsurance programs. The insured parties, which may include construction firms, public entities, engineering companies, and property owners, frequently face competing demands from victims, regulatory authorities, and subrogation claimants, each asserting independent rights to the available insurance proceeds.

The factual investigation underlying these disputes extends well beyond the policy documents. Determining the cause of a catastrophic loss typically requires forensic engineering analysis, reconstruction of project timelines, and evaluation of regulatory compliance at each stage of design, construction, and inspection. Coverage positions depend upon the conclusions reached in these technical analyses, as the application of policy exclusions for faulty workmanship, design defects, or regulatory violations turns on precisely how the loss originated and propagated.

• Coverage disputes involving infrastructure collapses, bridge failures, and large-scale structural defects
• Analysis of concurrent causation doctrines and allocation of losses among multiple policy periods and carriers
• Disputes over the application of professional liability, general liability, and builder’s risk policy provisions to catastrophic events
• Claims involving mass casualty incidents where coverage obligations intersect with tort liability and governmental immunity defenses
• Coordination of coverage positions across primary, excess, and reinsurance layers in multi-party loss scenarios
