A burst water main damages completed finishes two days before handover. A passer-by is injured by falling material outside the hoarding. Six months later, the employer alleges that an engineer’s design error caused costly remedial work. The contractors all risks versus liability question matters because these are three different loss scenarios, and no single policy should be assumed to answer all of them.
For project principals, contractors and finance leaders, the practical issue is not which policy is “better”. It is whether the project insurance programme properly separates damage to the works from legal responsibility to other parties, while also addressing professional services and contractual obligations. Buying on premium alone can leave a gap that only becomes visible when work has stopped and a claim has been notified.
Contractors all risks versus liability: the central difference
Contractors All Risks, commonly called CAR insurance, is principally designed to protect physical works during the construction period. It may respond to accidental physical loss of or damage to insured contract works, construction plant, temporary works and, where scheduled, materials on or off site. The intention is to help put damaged insured property back into the position contemplated by the policy, subject to its terms.
Liability insurance, by contrast, concerns the insured party’s legal liability to third parties. A third party could be a member of the public, a neighbouring occupier, the project employer, a subcontractor or another party, depending on the circumstances and the policy wording. Liability cover commonly addresses claims for bodily injury, illness, death or property damage where the insured is legally liable, as well as legal defence costs where provided.
The distinction is straightforward but commercially significant. If a fire damages installed mechanical and electrical equipment, the CAR section is likely to be the starting point. If that same fire spreads beyond the site and damages an adjacent building, third-party liability may become relevant. If the fire resulted from an alleged design specification failure, professional indemnity issues may also arise.
What a CAR policy is intended to protect
CAR insurance is project-focused. It is usually arranged for a defined contract, site and period of insurance, often from mobilisation or commencement until practical completion, with a maintenance or defects-liability period extension where agreed. The insured parties may include the employer, main contractor and subcontractors, but the schedule must be checked carefully. Being involved in a project does not automatically make every party an insured.
A well-structured CAR programme may include several sections. The material damage section addresses the contract works. It may also provide for debris removal, professional fees incurred to reinstate insured damage, expediting expenses and temporary repairs, each subject to stated limits. Construction plant and equipment may be covered under a separate section, often with different conditions. Delay in Start-Up or Advance Loss of Profit cover may be considered for projects where physical damage could delay revenue generation, although it is not a standard replacement for thorough contractual risk allocation.
CAR cover is not a maintenance warranty or a remedy for poor workmanship simply because rectification is expensive. The policy wording may exclude the cost of correcting defective materials, workmanship, design or plan, while potentially responding differently to resultant damage caused by that defect. The scope can vary substantially between wordings. A narrow defect exclusion and a broader one can produce very different outcomes after the same incident.
This is why the declared contract value, site conditions, construction methodology and handover arrangements deserve close attention. Underinsurance can affect a recovery, and an incomplete description of the works can create avoidable uncertainty. For renewable-energy installations, for example, the policy needs to reflect the value and transit of specialised components, testing and commissioning exposures, site security, weather vulnerability and the relationship between construction and operational insurance.
The handover point requires particular care
Practical completion is not always a clean insurance boundary. Sections of a project may be taken over early, equipment may be energised for testing, or the employer may occupy part of the premises before formal completion. CAR cover can change or cease at these milestones, while property and operational liability arrangements need to begin at the correct time.
Project teams should map the transition before it occurs. A gap between construction cover ending and operational cover commencing can be costly, especially where testing, commissioning and phased handover are involved.
What liability insurance is intended to protect
Public liability insurance, often referred to in contractual documents as third-party liability cover, is central to site operations. It is generally intended to protect against legal liability arising from accidental bodily injury to third parties or accidental loss of or damage to their property in connection with the insured business or project activities.
On a construction site, exposure can arise from excavation affecting a neighbouring structure, dust or vibration damaging adjacent property, a delivery vehicle incident, or injury to a visitor. The policy limit must reflect the project’s surroundings and the contractual requirement, rather than a generic figure carried over from a small, low-risk job. Work near live rail infrastructure, hospitals, public roads, densely occupied buildings or utilities merits a more searching review.
Employers’ liability is separate. It concerns liabilities to employees arising out of employment and should not be assumed to sit within public liability. In Singapore, statutory requirements and the organisation’s workforce arrangements, including labour-only subcontracting and overseas personnel, should be considered with care.
Liability policies also contain important boundaries. They may exclude contractual liability accepted beyond what the insured would have at law, damage to property in the insured’s care, custody or control, gradual pollution, work offshore, vibration or weakening of support, and certain high-hazard activities unless specifically declared or endorsed. These are not minor technicalities. They are often central construction risks.
Professional indemnity is different again
The most overlooked part of the contractors all risks versus liability discussion is professional indemnity insurance. Public liability ordinarily responds to bodily injury or property damage claims. It is not designed to cover pure financial loss arising from a professional error, negligent design, specification failure or incorrect advice.
A design-and-build contractor, architect, engineer, project manager or specialist consultant may have professional duties even where the contract describes their role in broad commercial terms. If a calculation error requires redesign and rework but has not caused injury or property damage to a third party, professional indemnity may be the relevant class of cover.
Professional indemnity is commonly written on a claims-made basis. In practical terms, the policy in force when a claim or circumstance is notified can be critical, subject to retroactive dates, prior-known-circumstances provisions and continuous cover terms. Maintaining appropriate cover after project completion matters where allegations may surface years later. Limits should also be tested against aggregate exposure across the business, not only the value of one contract.
Where project teams make costly assumptions
The most frequent error is treating the CAR policy as a complete project solution. It is not. CAR may insure physical loss or damage to the works, but it does not automatically meet every liability assumed under the building contract, every professional obligation or every delay-related consequence.
Another mistake is accepting contract insurance clauses without comparing them against the actual quotation and policy. A contract may require joint names, cross-liability, waiver of subrogation, non-vitiation protection, a particular defect wording, specified limits, existing-property cover or a maintenance period. If these requirements are not expressly reflected in the insurance arrangement, a certificate alone may offer false comfort.
Claims responsibility can also be unclear. On multi-party projects, the employer may arrange CAR, while contractors maintain their own public liability, employers’ liability, professional indemnity and plant cover. Alternatively, a main contractor may arrange a project policy. The correct structure depends on control, contractual allocation, project value, financier requirements and the parties’ respective exposures.
Questions to resolve before work begins
A disciplined insurance review should establish what is being built, who owns materials at each stage, which parties are insured, and how the contract allocates responsibility for existing structures and adjacent property. It should also identify whether design responsibility sits with the contractor or consultants, whether works involve testing and commissioning, and whether delay consequences require separate consideration.
Four areas frequently deserve specific attention:
- The sum insured should reflect the full reinstatement exposure, including free-issue materials, escalation, freight, duties and professional fees where appropriate.
- Liability limits should be assessed against the site environment, public exposure, contract conditions and potential accumulation of losses.
- Endorsements should be checked for defects, underground services, vibration, existing property, hot works, testing and commissioning, and maintenance obligations.
- Notification procedures should be understood by site management. Late notification, unauthorised repairs or admissions of liability can complicate claim handling.
For regional projects, local admitted-policy requirements, local compulsory covers, tax treatment, governing law and claims handling arrangements may also affect the insurance structure. A programme that appears adequate from Singapore may not satisfy contractual or regulatory requirements in Thailand, Vietnam or Cambodia.
A better way to assess the programme
Start with the project risk, not the policy label. Review the construction contract, scope of works, programme, site survey, method statements, subcontracting strategy and design responsibilities together. Then map each material exposure to the policy section that is expected to respond.
This approach exposes overlaps as well as gaps. CAR and public liability can both be relevant to one event, but for different components of loss. Professional indemnity may sit alongside them where a professional allegation is made. The objective is coordinated protection and clear accountability, not a collection of policies that appear comprehensive only on a schedule.
Coverage will always depend on the quotation, schedule, policy wording, endorsements, exclusions, limits and the facts of the claim. Before contract award or site mobilisation, ask for the proposed insurance structure to be tested against the project’s actual obligations. That conversation is far more valuable before a loss than after one.
