Definition:Course of construction insurance
🔨 Course of construction insurance is a property insurance product that covers buildings, structures, and associated materials against physical loss or damage while they are being erected, renovated, or extended. Often used interchangeably with contractors all-risk (CAR) insurance or builder's risk insurance — depending on the market and policy form — course of construction insurance addresses the unique vulnerability of a project during the period when it transitions from raw materials and open foundations to a completed, occupied structure. The coverage is standard across virtually every construction market globally, though policy forms, naming conventions, and regulatory treatment differ: in the United States, the product is typically known as builder's risk; in the UK and many Commonwealth markets, CAR is the prevailing term; and across continental Europe and Asia, engineering or erection all-risk policies serve a substantially similar function.
⚙️ Coverage under a course of construction policy generally begins when materials arrive on-site or construction commences — whichever is earlier — and extends through to practical completion, handover, or the issuance of a certificate of occupancy. Many policies also include a defects liability or maintenance period following handover, during which damage arising from construction defects discovered and repaired during that window remains covered. The sum insured is typically set at the full completed value of the project, including materials, labor, and often the value of existing structures if renovation work is involved. Underwriters evaluate project-specific factors such as construction methodology, geotechnical conditions, the contractor's safety record, proximity to flood or earthquake zones, and the adequacy of on-site risk management. Deductibles for natural catastrophe perils are often set as a percentage of the sum insured rather than a flat dollar amount, reflecting the severity potential. Extensions may include coverage for off-site storage, transit of materials, professional fees for redesign after a loss, and delay in start-up cover for the project owner.
🏢 Beyond protecting physical assets, course of construction insurance serves as a linchpin in project finance and contractual risk allocation. Lenders providing construction finance almost universally require evidence of adequate coverage before releasing funds, and standard construction contracts — such as those published by FIDIC, the American Institute of Architects (AIA), and the UK's Joint Contracts Tribunal (JCT) — contain detailed insurance clauses that effectively mandate this product. The question of who purchases the policy — the project owner, the main contractor, or a joint names arrangement — is a critical contractual negotiation point with significant implications for subrogation rights and claims handling. In markets with heavy infrastructure investment pipelines, including the Gulf states, India, and Southeast Asia, demand for course of construction insurance has grown substantially, placing pressure on capacity and driving increased participation from Lloyd's syndicates and reinsurers alongside local admitted markets.
