Definition:Construction all-risks insurance (CAR)
🏗️ Construction all-risks insurance (CAR) is a comprehensive insurance product that protects against physical loss of or damage to works under construction, along with associated materials, machinery, and third-party liabilities arising from the construction process. Written on an all-risks basis, the policy covers any cause of loss that is not expressly excluded, giving project stakeholders — including owners, main contractors, and subcontractors — a single, unified source of cover for the diverse perils that characterize construction activity. Known as CAR in most international markets and closely related to what is termed builders risk insurance in the United States, this product is foundational to the global engineering and construction insurance classes.
⚙️ The policy typically encompasses two principal sections: material damage to the contract works (Section I) and third-party liability (Section II), with a range of optional extensions tailored to the project's risk profile. These extensions may include coverage for the principal's existing property adjacent to the site, advance loss of profits or delay in start-up to compensate the project owner for revenue lost due to construction delays, professional fees, and removal of debris. The sum insured is generally set at the full completed value of the project, including materials and labor, and the policy runs from inception of works through completion, often extending through a contractual maintenance period. Deductibles are structured to reflect the nature of the project, with higher retentions common for natural catastrophe perils such as earthquake or flood. Placement typically involves brokers with specialized construction expertise arranging coverage across multiple carriers in subscription markets like Lloyd's, the European company markets, or Asian specialty hubs.
🌐 The significance of CAR insurance to the broader economy is difficult to overstate: virtually every major infrastructure, commercial, and industrial construction project worldwide relies on some form of this coverage. For underwriters, the line requires technical acumen in evaluating engineering risk, geotechnical conditions, contractor competence, and compliance with design standards. Claims in the construction class can be both frequent (minor site damage) and severe (catastrophic structural failures or natural disaster impacts), making reinsurance support essential for maintaining adequate capacity. Regulatory and contractual frameworks in different jurisdictions shape how CAR policies are structured — FIDIC contracts in international engineering, JCT contracts in the UK, and standard form agreements in other markets all influence the allocation of risk and the corresponding insurance requirements. As the global construction sector confronts new challenges — from climate-driven natural hazard escalation to the complexities of modular and green building methods — CAR insurance continues to evolve alongside the risks it was designed to address.
