Definition:Contractors' all risks (CAR)
🏗️ Contractors' all risks (CAR) refers to a widely recognized class of insurance coverage that protects construction projects against physical loss or damage on an all-risks basis throughout the construction period. Known by slightly different names across markets — "contractors' all risks," " contractors all risks insurance," and " construction all risks" are all common variants — CAR coverage has become a foundational product in the global engineering insurance market. The policy is designed to wrap the interests of project owners, principal contractors, and subcontractors into a single program, reducing the risk of uninsured gaps that could otherwise arise when multiple parties carry separate policies.
🔧 In practice, a CAR policy is triggered when construction work commences and typically remains active until the project is handed over to the owner, with many wordings extending through a maintenance or defects liability period. Coverage under Section I — the material damage section — responds to accidental loss or damage to the works, whether caused by fire, storm, flood, theft, collapse, or human error, subject to specific exclusions such as wear and tear, faulty design (depending on the wording and jurisdiction), and war. Section II provides third-party liability protection. Because construction projects vary enormously in scale and complexity, underwriters tailor each policy through negotiations with the broker, adjusting deductibles, sub-limits, and extensions to fit the risk profile. In subscription markets like Lloyd's, large CAR placements are commonly shared across multiple syndicates, with a lead underwriter setting terms that following markets accept.
📊 The enduring relevance of CAR coverage within the insurance industry stems from its role as an enabler of economic development. Without reliable construction insurance, banks and development finance institutions would face unacceptable exposure, and many projects would never break ground. For insurers and reinsurers, CAR is a technically intensive class that rewards deep expertise in engineering risk and catastrophe modeling — particularly as climate change amplifies flood, windstorm, and wildfire risks at construction sites worldwide. Regulatory expectations also shape the market: Solvency II capital requirements in Europe and equivalent regimes in Asia influence how much CAR exposure insurers can carry on their balance sheets. The class continues to evolve as new construction methods, modular building technologies, and digital risk management tools reshape both the risks and the way they are underwritten.
