Construction Delay Risk

Why it matters for underwriting

Beyond the physical damage covered under a standard CAR/EAR policy, a delay to project completion can generate substantial financial loss for the project owner and its financing or operating stakeholders, particularly where the completed asset was scheduled to start generating revenue on a fixed date. Underwriters assessing delay-in-start-up (advance loss of profit) cover need to understand which activities sit on the critical path, how much schedule contingency has been built in, and how exposed the project is to weather, supply-chain or permitting delays, since these same factors that trigger a physical loss claim also determine how long completion is pushed back and therefore the size of the financial loss.

Capturing the attribute and evidence

Proposal forms ask applicants to identify the main critical-path activities, the contingency allowed for each, and whether delay-in-start-up cover is being sought alongside the material damage section. Underwriters review the critical-path schedule or project programme, a delay-in-start-up exposure calculation setting out the estimated gross profit or fixed cost at risk per month of delay, and the main contract’s clauses on the contractual completion date and any liquidated damages payable for late delivery.

Effect on coverage, premium and conditions

Where delay-in-start-up cover is granted, the indemnity period and the monthly loss estimate directly drive the premium and the sublimit applicable to this section, which is typically underwritten separately from the material damage cover. Insurers commonly attach a condition requiring notification of any event likely to cause material delay, a minimum waiting period (deductible expressed in time) before delay cover responds, and may exclude delay caused by factors outside the scope of the underlying material damage cover, such as pure schedule slippage without a covered physical loss.

Mitigation measures

Delay risk is mitigated by building realistic contingency into the critical-path schedule for weather-sensitive and long-lead-time activities, maintaining a proactive supplier and permitting management process, agreeing early-warning notification protocols with the insurer for emerging delays, and structuring contracts with balanced liquidated damages and extension-of-time provisions that reflect genuine project risk.
