Definition:Contractor's all-risk (CAR) insurance
🏗️ Contractor's all-risk (CAR) insurance is a specialized property insurance product designed to cover physical loss or damage to construction projects during the course of erection, including materials, equipment, and temporary works on site. Unlike standard property policies that protect completed assets, CAR insurance addresses the unique exposures that arise while a structure is being built — a period when the project is at its most vulnerable to perils such as fire, storm, theft, collapse, and faulty workmanship consequences. The product is widely used across global construction markets and is often required by project owners, lenders, or government authorities as a condition of contract. In markets such as the United Kingdom, the Middle East, and Southeast Asia, CAR policies are a staple of engineering insurance portfolios, while in the United States similar coverage may be structured under builder's risk policies, though the underlying principles overlap considerably.
⚙️ A typical CAR policy is structured in multiple sections. Section I covers material damage to the contract works themselves, including permanent and temporary works, materials stored on or off site, and construction plant and equipment. Section II provides third-party liability coverage for bodily injury or property damage arising from construction activities. Many policies also include extensions for surrounding property, debris removal, professional fees for redesign, and escalation costs following a loss. The sum insured under Section I generally corresponds to the full completed value of the project, including materials and labor. Underwriters assess risk based on project type, construction methodology, soil conditions, location exposure to natural catastrophes, and the contractor's track record. In the Lloyd's and London markets, CAR risks frequently appear on subscription slips where multiple syndicates share capacity on large infrastructure projects.
💡 Construction represents one of the most capital-intensive sectors in the global economy, and the financial consequences of an uninsured loss during a build can be catastrophic for contractors, developers, and lenders alike. CAR insurance underpins the bankability of major projects by ensuring that financiers and project owners have confidence that physical damage will not derail completion timelines or trigger loan defaults. For insurers and reinsurers, the construction book offers premium volume but demands disciplined risk selection — large infrastructure projects can generate claims running into hundreds of millions of dollars, particularly when natural catastrophe perils overlap with construction exposure. The growing scale and complexity of global infrastructure investment, from transport corridors in Asia to energy transition projects in Europe, continues to make CAR insurance a strategically important line within the broader commercial insurance market.
