Contractor Claims on EPC Projects in India: Delay, Disruption, and Loss Assessment

Engineering, Procurement, and Construction contracts bundle design, equipment sourcing, and civil construction into a single wrapped obligation. That integration produces efficiencies in project delivery but concentrates risk in a way that makes insurance claims far more complex than those arising on separately let construction contracts. When a transformer fails during factory acceptance testing in South Korea and delays the commissioning of a 500 MW thermal power plant in Chhattisgarh by seven months, the chain of financial consequences touches the CAR policy for the physical loss, the DSU policy for the consequential loss of revenue, the contractor's professional indemnity cover if the failure traces to a design specification, and potentially the marine cargo policy that covered the shipment. Untangling which policy responds to which element of loss, and to what quantum, is the central challenge of EPC claims handling in India.

India's infrastructure ambitions have made this a pressing issue. The government's National Infrastructure Pipeline targets INR 111 lakh crore in infrastructure investment between 2020 and 2025, with execution continuing well into the 2030s. Highways, metro rail, airports, ports, power plants, and renewable energy projects all predominantly use EPC structures. The General Insurance Council reports that construction and engineering claims are among the fastest-growing commercial lines by both frequency and severity, with large project claims often running settlement timelines of three to five years from first notification to final agreement.

The fundamental characteristic that distinguishes EPC claims is the critical path dependency between engineering, procurement, and construction activities. A delay in finalising structural drawings (engineering) pushes back steel fabrication orders (procurement) which pushes back erection at site (construction). By the time the problem surfaces as a physical delay on site, its root cause may lie months earlier in a design coordination failure. This makes both loss attribution and insurance responsibility genuinely contested, and it is why delay analysis is a forensic discipline rather than an accounting exercise.

Delay claims arise when project completion is pushed beyond the contracted date. The contractor claims additional time (an extension of time) and additional money (prolongation costs) for delays caused by events attributable to the employer or to neutral causes. Delay claims on large Indian EPC projects routinely reach INR 50 to 500 crore and are supported by programme analyses showing the critical path impact of the delaying event. Under most Indian EPC contracts, including those based on FIDIC Silver Book and NITI Aayog model EPC conditions, the contractor must give timely notice of delay (typically 28 days of becoming aware) and must maintain contemporaneous records to substantiate quantum. Failure to give notice on time is the single most common reason that otherwise legitimate delay claims are partially or wholly rejected.

Disruption claims are analytically more difficult than delay claims. Disruption occurs when the contractor's planned method of working is interfered with in ways that increase cost without necessarily extending the programme. A contractor planning to pour concrete slabs in an uninterrupted sequence finds that the employer's variations have created a fragmented programme with waiting periods, remobilisation costs, and workforce inefficiency. The total project duration may be the same, but the cost is materially higher. Disruption is measured through productivity analysis: comparing planned productivity rates (labour-hours per unit of work) against actual rates on affected versus unaffected sections of the project.

Acceleration claims arise when the contractor incurs additional costs to recover time lost due to employer-caused delays. If a power plant project falls behind schedule due to late delivery of the employer-supplied boiler, and the employer instructs the contractor to accelerate to maintain the commercial operation date, the contractor is entitled to recover the acceleration costs: overtime, additional shifts, additional plant, and premium logistics. Acceleration claims are particularly sensitive because they often involve expenditure before the claim basis has been formally agreed.

Variation claims on EPC projects are complicated by the design-build nature of the contract. The contractor's obligation is to deliver a specified output, and changes to scope trigger adjustment under the contract's variation mechanism. Disputes arise over whether a particular change constitutes a variation (and therefore entitles the contractor to additional time and money) or whether it falls within the original scope. On Indian power and industrial EPC projects, scope disputes over civil foundations when equipment dimensions change after contract award are among the most common sources of variation claims.

Force majeure claims have assumed new prominence after the experience of COVID-19 disruptions to Indian construction projects between 2020 and 2022. Under FIDIC contracts, force majeure is defined narrowly and requires that the event be beyond the party's control, unforeseeable, unavoidable, and not substantially attributable to the other party. Under NITI Aayog model EPC conditions used on national highway projects, the list of force majeure events is exhaustive rather than illustrative, which has generated disputes about whether events such as extended rainfall or urban flooding qualify when they are not specifically listed. The insurance implications of force majeure depend entirely on whether the event is an insured peril under the CAR policy.

A Contractors All Risk (CAR) policy provides all-risk cover for physical loss or damage to the works, temporary works, and construction plant during the construction period. On a large Indian EPC project, the CAR policy is the primary insurance instrument and is typically placed in the Indian market through a lead insurer with facultative reinsurance support from international markets including Lloyd's of London for projects above INR 500 crore in total contract value.

The CAR policy structure under IRDAI-filed engineering insurance products covers Section I (material damage) and Section II (third-party liability). Section I extends to the value of the permanent works, temporary works, and contractor's plant and equipment. The sum insured on large projects can run to INR 2,000 to 15,000 crore and above. Deductibles are negotiated case-by-case but commonly range from INR 50 lakh to INR 5 crore for standard perils, with higher deductibles for testing and commissioning damage, flood, and earthquake.

Common disputes in CAR claims on Indian EPC projects include:

The design exclusion: CAR policies standardly exclude the cost of rectifying faulty design, but cover the resulting damage to other parts of the works. When a retaining wall collapses due to inadequate design, the cost of redesigning and rebuilding the wall is excluded, but damage to completed road pavement below the wall may be covered. Drawing this boundary is frequently disputed, particularly on EPC contracts where the contractor is responsible for both design and construction.

Testing and commissioning exclusions are especially contentious on power plant and industrial plant EPC projects. Most CAR policies exclude damage occurring during testing and commissioning unless specifically endorsed. The precise point at which a project moves from construction to testing, and whether individual sections can be at different phases simultaneously, creates coverage disputes on large plants with phased commissioning.

Consequential loss: Standard CAR policies cover only direct physical loss. Loss of revenue arising from delayed commissioning is not covered under Section I and requires a separate Delay in Start-Up (DSU) policy.

A realistic scenario: during erection of a 400 kV transmission tower line in Rajasthan, a tower section collapses during a dust storm, damaging 12 towers and requiring four months of remediation. The physical damage claim (replacement of towers, reinstatement of conductor stringing) is a Section I claim under the CAR policy, estimated at INR 18 crore. The resulting delay to commissioning of the associated solar farm is a separate DSU claim. The lead insurer appoints a loss adjuster who jointly inspects the site with the contractor, reviews the erection records, and issues a survey report within 30 days. The deductible is INR 75 lakh. The net CAR recovery is approximately INR 17.25 crore.

Delay in Start-Up (DSU) insurance, also referred to as Advanced Loss of Profits (ALOP) for manufacturing and industrial projects, covers the financial consequence of a delay in achieving commercial operation that results from an insured physical damage event under the associated CAR or EAR policy. This is the critical distinction: DSU does not respond to all delays. It responds only to delays caused by insured physical damage. A delay arising from engineering design errors, supplier insolvency, regulatory approvals, or labour disputes is not covered under a standard DSU policy.

The DSU policy indemnifies the project owner (or lender, if structured for project finance) for the loss of revenue or profit that would have been earned during the period of delay, subject to a maximum indemnity period (commonly 12 to 24 months) and a time excess (commonly 30 to 90 days). On a 400 MW wind farm in Tamil Nadu with a contracted offtake under a Power Purchase Agreement at INR 2.80 per unit, a six-month delay caused by cyclone damage to turbine foundations could produce a DSU claim of approximately INR 80 to 120 crore depending on capacity factor assumptions.

The gap between insured and uninsured delay causes creates a significant coverage planning issue on Indian EPC projects. In practice, the most common sources of construction delay in India are:

• Land acquisition and encumbrance clearance delays (uninsured)
• Statutory approval delays (uninsured)
• Supply chain and procurement delays (uninsured unless arising from insured physical damage to the manufacturer's plant)
• Labour disputes and site shutdowns (generally uninsured unless arising from a covered event)
• Extreme weather events (insured if the policy covers the specific peril; flood and cyclone are typically covered with appropriate deductibles)
• Equipment failure during erection or testing (insured if physical damage is confirmed)

Project owners and lenders on large Indian infrastructure projects have increasingly sought to negotiate enhanced DSU wordings that extend coverage to a broader set of delay causes, including supply chain disruptions and regulatory approval delays. Reinsurers have been cautious about accepting such extensions, and where they are granted, the premium loading is significant.

The evidentiary foundation of a delay or disruption claim on an Indian EPC project is the contemporaneous record. Courts, arbitrators, and claims adjusters assess delay claims by comparing what the contract programme said would happen against what actually happened and why. Without contemporaneous documentation, even a legitimate claim becomes difficult to substantiate at the quantum required for recovery.

The minimum documentation that a contractor should maintain from day one of an EPC project includes:

A baseline programme in Primavera P6 or equivalent, agreed with the employer at contract award and showing the planned sequence, durations, and logic links between all major activities. The baseline programme is the reference against which all delays are measured.

Programme updates on at least a monthly basis, showing actual progress against plan, current forecasts, and the specific activities on the critical path. Without regular updates, it is impossible to demonstrate that a particular event extended the overall project duration rather than being absorbed by float.

Daily site records covering weather conditions, workforce deployed by trade and nationality, plant and equipment on site, areas of work in progress, and any access restrictions. Weather records should be sourced from the nearest Indian Meteorological Department station and cross-referenced with site records.

Correspondence records including all letters, emails, and meeting minutes relating to variations, employer instructions, late information, delayed approvals, and any events that caused disruption. Notices given under the contract's claims clause should be filed by reference to the clause number and the specific event.

Procurement records showing planned versus actual delivery dates for all major equipment and materials, with supplier correspondence explaining any delays.

When a delay claim is presented, the contractor typically engages an independent delay analyst, a specialist with programme analysis qualifications (such as AACE certification or equivalent) who prepares a formal delay analysis report. The methodology used most commonly in Indian arbitration and adjudication is the time impact analysis (TIA) method, which inserts each delay event into the programme at the time it occurred and measures the impact on the projected completion date. The TIA is preferred by FIDIC dispute boards and by the Arbitration and Conciliation Act 1996 arbitration tribunals because it reflects the dynamic state of the programme at the time the delay occurred rather than analysing everything retrospectively.

Loss adjusters appointed by insurers on large delay-related claims typically request access to all programme data and instruct their own independent delay analyst to validate or critique the contractor's analysis. On complex EPC projects, it is not unusual for the employer's analyst, the contractor's analyst, and the insurer's analyst to reach materially different conclusions about the delay quantum, particularly where multiple concurrent delay causes are present. Concurrent delay (where employer-caused and contractor-caused delays overlap) is among the most contested issues in EPC claims and is treated differently under English law (which governs many Indian project contracts) and Indian law.

Liquidated damages (LDs) are pre-agreed daily or weekly penalties payable by the contractor to the employer for each day of delay beyond the contracted completion date. On Indian EPC projects, LD rates typically run at 0.1% to 0.5% of the contract price per week, subject to a cap of 10% to 15% of the contract price. On a INR 2,000 crore power plant EPC contract, the cap on LDs can reach INR 200 to 300 crore, which is a material financial exposure for the contractor.

Liquidated damages are generally not insured under standard CAR policies, which cover physical loss and damage rather than contractual penalties. Some contractors have sought cover for LD exposure through contract works policies with contractual liability extensions, but such extensions are narrow, expensive, and rarely match the full LD exposure.

The interaction between LDs and DSU claims creates a recurring dispute on Indian infrastructure projects. Consider a toll road project where the concessionaire has contracted with an EPC contractor under an agreement that passes through LDs from the concession authority. The EPC contractor faces LDs for delay. At the same time, the concessionaire claims on its DSU policy for the loss of toll revenue during the delay period. The insurer's DSU indemnity reduces the concessionaire's actual loss. The contractor asks: does the concessionaire's DSU recovery reduce the LDs owed under the contract? The answer, under most Indian EPC contracts, is no: LDs are a separate contractual mechanism and are not reduced by the employer's insurance recovery. This result can produce what some practitioners call a windfall for the project owner, receiving both LD payments from the contractor and DSU indemnity from the insurer for the same period of delay.

The broader dispute over who bears insurance responsibility on EPC projects is a live issue in the Indian market. The FIDIC Silver Book (used on many Indian power and process plant EPC projects) places the obligation to insure the works with the contractor but allows the parties to agree that the employer will arrange the joint names CAR/DSU policy. When the employer arranges the policy, the contractor has no direct policy rights and must rely on the employer to pursue the CAR claim and remit the proceeds. This creates obvious conflicts of interest when the employer and contractor are in dispute about the cause of the loss. Projects financed by multilateral lenders (World Bank, ADB, AIIB) typically require joint names insurance with loss payee clauses protecting lenders, reducing but not eliminating the scope for such disputes.

Two contract families dominate Indian EPC projects: FIDIC conditions (Red Book for traditionally let construction, Silver Book for EPC turnkey, Yellow Book for plant and design-build) and the NITI Aayog model concession/EPC conditions used on PPP projects in highways, ports, and airports. Their insurance clauses differ in ways that materially affect claims handling.

FIDIC Silver Book Clause 18 requires the contractor to effect and maintain insurance covering the works, contractor's equipment, and third-party liability. The insured parties include both the contractor and the employer (joint names). Clause 18.2 specifies minimum coverage amounts with blanks to be filled in the contract particulars. FIDIC's insurance framework is designed for international projects where the contractor is typically a global EPC firm with access to sophisticated insurance markets. The FIDIC clause gives the contractor discretion over the policy structure, subject to the employer's approval.

NITI Aayog model conditions for national highway projects use a different approach. The EPC contractor is required to maintain specified categories of insurance, but the model form does not prescribe the DSU or ALOP cover in its standard form. This gap is addressed (or not addressed) in the schedule of insurance requirements agreed between the authority (NHAI or the state highway department) and the lenders. In practice, the insurance schedule varies significantly across projects, and contractors have been caught by requirements that emerge during project execution rather than at contract award.

On metro rail projects, the contract conditions used by DMRC, BMRCL, and other metro corporations combine elements of FIDIC Yellow Book and bespoke metro authority conditions. The metro authority typically arranges the CAR policy as employer, with the contractor named as co-insured, but the contractor is responsible for maintaining third-party liability cover for its construction activities. Delay claims on metro projects are particularly complex because construction often occurs in live urban environments where external interference (public utility services, underground structures not shown on records, public agitation) is a frequent source of delay, and attribution of those delays to insured versus uninsured causes requires careful contemporaneous documentation.

On port projects under the Major Port Trusts Act and the revised Port Authority Act 2021, the insurance structure follows the underlying PPP concession agreement. Ports using Model Concession Agreement templates from the Ministry of Ports, Shipping and Waterways typically require the concessionaire to maintain CAR and DSU cover with lender-approved insurers, with terms reviewed annually during the construction period. Port construction claims are characterised by marine interface risks (wave action, tidal effects on caissons and breakwaters) that require specialised marine engineering expertise at both underwriting and claims stages.

A realistic picture of how delay and damage claims develop on large Indian EPC projects helps risk managers and contractors set accurate expectations for the claims process.

Scenario A: Transmission line project in Odisha, cyclone damage during construction

In August 2024, Cyclone Dana makes landfall near Puri and destroys 47 transmission towers of a 765 kV line being constructed by an EPC contractor for the Power Grid Corporation of India. The contractor submits FNOL to the CAR insurer (a consortium led by New India Assurance with facultative reinsurance) within 48 hours. An independent loss adjuster is appointed and reaches site within seven days. The survey takes three weeks given the scale of damage and access difficulties. The loss adjuster's interim report establishes a preliminary estimate of INR 42 crore for physical damage. The contractor submits a delay analysis 90 days later showing a seven-month delay to commissioning. The DSU insurer (whose policy is assigned to the Power Finance Corporation as project lender) appoints a separate delay analyst. The parties agree on five months of recoverable DSU delay after excluding two months attributable to pre-existing programme slip (uninsured contractor-caused delay). DSU recovery at INR 8.5 crore per month for five months: INR 42.5 crore. Total insured recovery: INR 84.5 crore across CAR and DSU policies. Settlement finalised 22 months after FNOL.

Scenario B: Gas processing plant in Gujarat, mechanical failure during pre-commissioning

A gas processing plant EPC project reaches pre-commissioning in November 2025. During a pressure test of the primary separator vessel, a flange connection fails and causes a fire that damages the separator and adjacent pipework. The contractor's CAR policy covers the physical damage but the testing and commissioning exclusion is invoked by the insurer for the separator itself. After a three-month dispute handled through the policy's engineering expert determination clause, the insurer agrees to cover 65% of the separator repair cost (INR 11 crore) on the basis that the failure was not caused by inherent vice in the design or manufacturing but by a construction defect in the flange installation. Commissioning is delayed by four months. No DSU policy was in place. The project lender (HDFC Bank infrastructure fund) absorbs the revenue loss as a non-recoverable project cost.

Scenario C: Highway project in Telangana, employer-caused delay claim

A contractor on a INR 850 crore national highway EPC contract submits a delay claim for 14 months of delay caused by late handing over of land by NHAI. The claim includes prolongation costs of INR 63 crore (site overheads, staff costs, finance charges) and disruption costs of INR 21 crore (idle plant, productivity loss on realigned work). The contractor's delay analyst prepares a TIA using the as-built programme and NHAI correspondence records. NHAI's independent expert disputes 6 months of the 14-month delay as contractor-caused. The matter proceeds to the NHAI Dispute Review Board (DRB) under the contract. The DRB issues a non-binding recommendation of INR 47 crore, which is accepted by NHAI subject to audit. This is a contractual claim against the employer, not an insurance claim. However, the contractor's own CAR insurer's loss adjuster reviewed contemporaneous records as part of investigating whether any part of the delay was caused by an insured event. Finding none, the CAR insurer's role in the matter ended at that stage.
