Definition:Construction all-risk (CAR) insurance
🔨 Construction all-risk (CAR) insurance is a comprehensive insurance policy that provides coverage for physical loss of or damage to construction projects — encompassing the works under construction, materials, plant, and equipment — against a wide range of perils unless specifically excluded. While the term overlaps significantly with construction all risk (CAR) and builder's risk, "CAR insurance" is the phrasing most commonly encountered in international and London market policy wordings, where it has a long-established pedigree as the standard form for insuring civil engineering and building projects worldwide.
⚙️ A CAR insurance program is typically structured in two main sections. Section I covers material damage to the contract works, including temporary works, materials stored on or off site, and — via extension — surrounding property of the principal. Section II provides third-party liability protection for bodily injury and property damage arising out of the construction activities. Optional extensions can add delay in start-up (DSU) cover, which indemnifies the project owner for revenue losses if the project completion is delayed by an insured event. Underwriters set premiums based on the total project value, construction type, duration, geographic catastrophe exposure, and the contractors' experience and safety records. Maintenance periods — typically twelve to twenty-four months after handover — are also included, covering defects that manifest during that window.
🌍 For large-scale infrastructure and real estate developments, CAR insurance is often the single largest risk transfer mechanism protecting all parties involved — owners, main contractors, subcontractors, and financiers. Lenders routinely require evidence of CAR coverage before releasing project finance, and surety companies factor the quality of the insurance program into their bond decisions. In emerging markets experiencing rapid construction growth, demand for CAR insurance is expanding, and specialty carriers with deep engineering knowledge command significant market share. The complexity of modern megaprojects — involving tunneling, offshore elements, or advanced materials — continues to push reinsurers and primary insurers to innovate on policy wordings and risk assessment techniques.
