Contract Works and Delay in Startup Insurance

A construction project can suffer insured physical damage and finish later than planned. Contract works insurance may pay to repair the damaged works, but it doesn’t automatically replace the project owner’s delayed revenue or additional finance costs.

That is where delay in startup insurance may be considered in 2026. The cover is specialised, evidence-heavy and tied to the project’s critical path.

What is delay in startup insurance?

Delay in startup insurance is cover for specified financial loss caused by a delay to a project’s planned commercial operation following insured physical loss or damage, subject to the policy wording. It is also called delayed start-up or advance loss of profits cover.

It is not general protection against late completion. Planning delays, approval problems, contractor performance or lack of funds don’t become insured merely because the completion date moves.

Question	Contract works section	Delay in startup section
What is insured?	Physical works, materials and specified property	Defined financial loss after an insured delay
What starts the claim?	Covered physical loss or damage	Resulting delay to commercial operation
Whose interest is central?	Principal, builder and other insured parties	Project owner, lender or revenue interest
What evidence matters?	Repair scope and cost	Critical path, dates and financial model

Tank’s contract works insurance guide explains the physical-damage layer.

What can trigger delay in startup cover?

Check whether insured damage under the contract works policy affected the critical path. The wording then determines whether the delay section responds, along with the waiting period, indemnity period, insured financial items and exclusions.

Project schedules matter because not every damaged item delays commercial operation. Damage to a critical transformer may affect the opening date differently from damage to a non-critical area with available float.

Infrastructure Australia’s 2025 performance statement says project design and development maturity affects certainty of cost and schedule. That is project-governance evidence, not an insurance trigger, but it supports documenting schedule assumptions.

What financial loss can be considered?

The insured financial interest can include defined gross profit, revenue, rent, finance costs or other agreed items, depending on the project and wording. The amount needs a supportable model rather than a round estimate.

The Australian Government’s construction industry guide distinguishes contract or construction works cover for damage during work from other business covers. Delay in startup adds another distinct layer.

Tank’s business interruption glossary helps explain the financial-loss concept, but an operating-business interruption policy and a pre-opening project delay policy are not interchangeable.

What is Tank’s four-gate DSU test?

Tank’s original four-gate test separates the questions that can otherwise become blurred in a project delay discussion:

• Damage gate: did insured physical damage occur under the contract works section?
• Programme gate: did that damage move the scheduled completion date on the critical path?
• Time gate: does the delay sit beyond any waiting period and within the stated indemnity period?
• Financial gate: can the insured financial loss be supported by the agreed model and records?

Passing one gate doesn’t answer the next. The test is a preparation framework, not a statement that a particular policy responds.

How can the evidence be reconciled before submission?

Use one reconciliation card to connect the programme, damage and financial records. Tank’s original DSU evidence card keeps four evidence streams on the same page:

Evidence stream	Record on the card	Check before submission
Programme	Baseline date, latest date and critical-path activity	Dates reconcile with the current programme
Damage	Affected item, repair scope and lead time	The physical-damage section and evidence source are identified
Time	Waiting period, requested indemnity period and recovery steps	Each period has a documented basis
Financial	Insured item, calculation basis and source record	Figures reconcile with the project model and sign-off

The card is a submission-preparation tool. It does not predict whether a loss will be covered or how a claim will be calculated.

What belongs in a DSU evidence checklist?

An underwriter may ask for a connected project and financial file. Consider assembling:

• Contract value, scope, parties and insured interests.
• Baseline programme and critical-path report.
• Planned testing, commissioning and commercial-operation dates.
• Long-lead equipment and replacement lead times.
• Project revenue, rent or profit model with source documents.
• Debt service, standing charges and fixed operating costs.
• Proposed waiting and indemnity periods.
• Dependencies on utilities, suppliers, tenants or off-site assets.
• Contingency plans and schedule float.
• Valuation method, escalation and professional sign-off.

For recurring builders, annual contract works policies can be compared with project-specific arrangements. Commercial builder cover and the contract works claims guide add practical context.

Frequently asked questions

Is delay in startup automatically included in contract works insurance?

No. It is a separate cover question and must be requested, underwritten and shown in the policy.

Does delay in startup cover every project delay?

No. It generally depends on delay caused by insured physical loss or damage under the project policy, subject to the wording.

What evidence is needed for delay in startup cover?

The underwriter may request the project programme, critical path, revenue model, finance costs, indemnity period and dependency details.
