Construction All Risks Pricing for Metro and Elevated Highway PPP Projects in India: 2026 Underwriting Position

Indian infrastructure construction has expanded materially through 2020 to 2026 with metro rail projects active in over 20 cities and elevated highway PPP projects under execution across the national highway network. The construction capital deployed annually in metro and elevated highway segments alone exceeds INR 2.5 lakh crore, with the insured construction value across the live project pipeline approaching INR 12 to 15 lakh crore. The Construction All Risks (CAR) market on this exposure has produced repeated loss clusters that have driven the 2026 underwriting tightening.

The loss patterns through 2022 to 2025 included multiple tunnel boring machine (TBM) jams and collapses on metro projects in Bengaluru, Chennai, Mumbai, and Delhi, several launching girder failures and segmental box-girder collapses on elevated metro and highway projects, multiple formwork failures during deck pour on elevated highway PPP projects, station box excavation collapses on metro projects, and third-party utility damage producing extended dispute and consequential loss claims.

The cumulative claims experience drove the international reinsurance market repricing of Indian CAR through the 2024 to 2026 cycle. The 2026 treaty renewal at 1 April produced rate increases of 25 to 45 percent on metro and elevated highway PPP CAR placements, capacity reductions on the most exposed individual projects, and policy wording tightening across surveyor-flagged exclusions including design defect, faulty workmanship, and contractual penalty exposure.

The Indian market response has included tightened underwriting at placement, with engineering survey at design stage now standard for large metro and elevated highway projects rather than only at construction stage. The MMRDA, NHAI, and various state metro authorities have updated their insurance specifications through 2024 to 2026 to reflect the market position, with explicit requirements on CAR cover scope, Section II limits, ALOP placement, and contractor compliance evidence.

This guide covers the 2026 CAR underwriting framework for Indian metro and elevated highway PPP projects. It addresses Section I material damage and Section II third-party liability structuring, ALOP cover, the EAR versus CAR distinction, common surveyor-flagged exclusions, the MMRDA and NHAI specifications, and the recent project loss patterns shaping the market.

CAR policies are structured around two primary sections plus optional extensions. Understanding the structure is essential for both placement design and claim resolution.

Section I: Material Damage

Section I covers physical loss or damage to the contract works during construction. The cover applies to all works at the project site including permanent structures under construction, materials on site intended for incorporation, contractor's plant and equipment if specifically listed, and temporary works. The sum insured under Section I should reflect the completed value at risk including contractor's costs, profit margin, escalation, and additional cover for the cost of removing debris and accelerating restoration.

For a metro project, Section I covers the tunnels under construction, the station boxes under excavation and concrete pour, the elevated viaduct under segmental construction, the depot and yard facilities, and the supporting infrastructure (substations, signalling rooms, ventilation shafts). For an elevated highway PPP, Section I covers the piers, pier caps, segmental box girders, deck slab, approach embankments, and structural appurtenances.

Section I sum insured for a major metro contract package typically runs INR 3,000 to 8,000 crore depending on package scope and length. For an elevated highway PPP of 60 to 120 km length, the Section I sum insured typically runs INR 4,000 to 12,000 crore. The largest individual metro and highway contracts can carry Section I sum insured above INR 15,000 crore, placed through complex layered structures with multiple insurers and reinsurance support.

Section II: Third-Party Liability

Section II covers the contractor's third-party liability arising from the construction works including bodily injury to third parties, property damage to neighbouring property, and consequential financial loss in some structures. The cover responds to claims brought by parties outside the construction contract: neighbouring property owners, road users, members of the public, utility providers, and government authorities for damage caused by the construction activity.

Section II limits on Indian metro and elevated highway projects in 2026 typically run INR 50 to 250 crore per occurrence and aggregate, with limits scaled to the project's proximity to populated areas, the depth of underground works, and the value of neighbouring property. Mumbai metro projects typically carry the highest Section II limits given the dense urban surroundings, while suburban or peripheral highway projects can carry lower limits.

The 2026 Section II wording typically distinguishes between bodily injury (covered on first-dollar basis subject to retention), property damage (covered subject to retention and exclusions), and consequential financial loss (typically excluded or covered only with explicit endorsement). The financial loss exclusion is the most contested wording element because utility outage damage and resulting business interruption on neighbouring commercial property is a frequent loss type that the standard wording does not respond to.

Section III and beyond: Optional extensions

Most CAR placements on metro and elevated highway projects include additional extensions beyond the basic Section I and II structure.

1. Maintenance period cover extends Section I cover for damage occurring during the maintenance period (typically 12 to 24 months after completion) arising from causes occurring during the construction period.
2. Cross-liability between named insureds (principal, contractors, subcontractors) provides protection for claims by one named insured against another.
3. Removal of debris and clean-up costs beyond the basic Section I cover, important for tunnel and station box losses where the clean-up cost can be material.
4. Professional fees covering architect, engineering, and consultancy fees for the restoration design and supervision.
5. Expediting expenses covering the cost of accelerating restoration to limit the overall delay.

The extensions are negotiated at placement with limits scaled to the underlying project exposure.

Advance Loss of Profits (ALOP), also known as Delay in Start-Up (DSU), is the financial loss cover that responds when insured damage during construction delays project commissioning and produces a delay in the project's revenue stream. ALOP is the financial complement to CAR Section I and is the primary financial protection for PPP project sponsors and lenders.

The ALOP trigger and cover scope

ALOP responds when: (1) physical damage occurs to insured works during the construction period, (2) the damage is covered under CAR Section I, (3) the damage causes a delay in the project's planned commercial operation date (COD), and (4) the delay produces a measurable financial loss in the form of revenue shortfall or financing cost extension.

The ALOP cover is calibrated to the project's expected revenue or to the financing cost during the delay period, with the indemnity computed on a daily or monthly basis multiplied by the delay duration. The indemnity period is typically 12 to 36 months from the originally scheduled COD, with the choice reflecting the realistic worst-case delay timeline.

ALOP for metro projects

Metro projects typically place ALOP cover responding to the project's expected revenue from the commencement of commercial operations. The revenue assumption is built from the project's traffic forecast, the fare structure, and the operating cost. For a major metro line with planned COD revenue of INR 800 to 1,500 crore in the first year of operation, the ALOP cover typically responds to INR 65 to 125 crore per month of delay loss.

The ALOP indemnity period for metro projects is typically 18 to 24 months. The historical claim pattern shows that ALOP claims on metro projects arise primarily from TBM-related delays (jams, collapses requiring rescue tunnel construction), station box collapse delays, and viaduct erection delays from launching girder failures.

ALOP for elevated highway PPP

Elevated highway PPP projects typically place ALOP cover responding to the project's expected toll revenue or annuity payment from the financing structure. For a highway PPP with planned annual revenue of INR 400 to 800 crore, the ALOP cover typically responds to INR 35 to 65 crore per month of delay loss.

The ALOP indemnity period for highway PPP projects is typically 12 to 18 months, with the shorter period reflecting the simpler construction sequence relative to metro projects. The historical claim pattern shows that ALOP claims on elevated highway PPP arise primarily from launching girder failures, formwork collapses during deck pour, and pier construction delays from foundation issues.

ALOP placement and pricing

ALOP is placed alongside the CAR Section I cover, typically with the same insurer or insurer panel to align the policy response. The ALOP sum insured is the gross profit at risk during the indemnity period, computed from the project's revenue forecast minus variable costs. ALOP pricing typically runs at 1.2 to 3.5 percent of sum insured annually, with the rate scaled to the project's construction risk profile, the contractor's experience, and the underlying Section I rate.

Lender and sponsor protection through ALOP

ALOP is critical to PPP project sponsors and lenders because the project's debt service depends on the COD revenue. A 12 to 24 month delay can produce debt service shortfalls that the project's financial structure cannot absorb without ALOP recovery. Lenders typically require ALOP placement as a financing condition, with assignment of ALOP proceeds to the lender as security.

The 2026 ALOP market position

The 2026 ALOP market is materially tighter than the 2022 to 2023 position. The TBM jam losses on Bengaluru and Chennai metro projects through 2023 to 2024 produced substantial ALOP claims that drove the underwriting tightening. Current ALOP placements require detailed pre-placement diligence on the construction schedule, the contractor's track record, the geotechnical risk assessment, and the project's contingency planning.

The Indian engineering insurance market uses two primary contract works covers: Construction All Risks (CAR) for civil and structural works, and Erection All Risks (EAR) for plant and machinery erection. The distinction matters because the wordings, exclusions, and pricing differ materially between the two covers.

CAR for civil and structural works

CAR cover is the dominant placement for metro rail and elevated highway projects where the project consists primarily of civil and structural construction (tunnels, stations, viaducts, embankments, bridges, deck slabs). The CAR wording is designed for civil-construction risk patterns including formwork failures, concrete pour defects, structural collapse, and underground excavation events.

EAR for plant and machinery erection

EAR cover is the dominant placement for power plant, refinery, petrochemical, and industrial plant construction where the project consists primarily of plant and machinery erection. The EAR wording is designed for erection-risk patterns including equipment handling damage, commissioning incidents, and testing-stage failures.

CAR or EAR for hybrid metro and infrastructure projects

Metro projects with substantial rolling stock procurement, signalling system installation, depot equipment installation, and electrical and traction infrastructure typically use a CAR policy for the civil and structural works supplemented by an EAR policy for the plant and machinery components, or use an integrated CAR-EAR placement covering both segments. The choice depends on the project structure and the contractor scope.

Wording differences that matter at claim time

Three wording differences matter at claim time.

1. Testing and commissioning cover: EAR wordings typically include testing and commissioning cover at extended limits, while CAR wordings include it at reduced limits or with specific exclusions. The distinction matters for metro signalling system commissioning losses and for power infrastructure commissioning losses where multiple integrated systems must be tested together.
2. Faulty workmanship exclusion: both wordings exclude the cost of repairing or replacing the defectively-workmanshipped item itself, but EAR wordings typically have more specific carve-outs around the consequential damage to other property arising from the defect.
3. Maintenance and warranty period cover: EAR wordings typically include warranty-period cover for damage during the warranty period arising from causes during the erection period, while CAR wordings include maintenance-period cover with different trigger language.

Pricing differences

EAR pricing is typically higher than CAR pricing for equivalent sum insured, reflecting the higher loss frequency on testing and commissioning events. The pricing differential is most pronounced for projects with substantial commissioning-stage exposure including metro signalling, traction systems, and depot equipment.

For brokers placing metro and elevated highway covers, the practical advice is to scope the project precisely at placement and select CAR or EAR (or both) based on the actual contractor scope and exposure pattern. Misclassification at placement can produce cover gaps or pricing inefficiency that emerge only at claim time.

Indian CAR policies in 2026 carry tighter exclusion wording than at any point in the recent past. The exclusions that produce the most claim-time dispute on metro and elevated highway projects are the design defect, faulty workmanship, and contractual penalty exclusions.

Design defect exclusion (DE wordings)

Design defects are excluded under standard CAR wording using one of several variants of the London Engineering Group (LEG) wording.

1. LEG 1: excludes the entire loss arising from design defect, including both the defective design itself and the consequential damage. The most restrictive wording, rarely used on Indian metro and elevated highway placements in 2026.
2. LEG 2: excludes the cost of repairing or replacing the defectively-designed item itself but covers the consequential damage to other property arising from the defect. The standard Indian placement in 2026.
3. LEG 3: covers both the defective item and the consequential damage. The most cedant-favourable wording, negotiated only for the highest-quality insureds with strong design-stage diligence.

The distinction matters materially on metro and elevated highway projects where design issues frequently underlie major losses. A launching girder failure may be the consequence of a design assumption error in the girder rating, a formwork collapse may follow design omission of a critical bracing, and a tunnel collapse may follow a geotechnical design underestimate. Under LEG 2 wording, the design-defective component itself is uninsured but the consequential damage to other works is covered. Under LEG 3 wording, both are covered.

The 2026 underwriting position favours LEG 2 for most placements with LEG 3 selectively available at premium loading for highest-quality insureds. Brokers placing CAR covers should clarify the LEG wording at placement and ensure the wording matches the project's actual design-risk profile.

Faulty workmanship exclusion

The faulty workmanship exclusion operates on similar wording structures to the design defect exclusion, with LEG-equivalent variants for the workmanship-defective component versus the consequential damage. The exclusion is enforced through documentation at claim time: the surveyor reviews the construction records, the quality control documentation, and the workmanship inspection reports to determine whether the loss arose from faulty workmanship or from an unrelated cause.

The 2026 placement practice typically uses LEG 2-equivalent workmanship wording, covering the consequential damage but excluding the workmanship-defective item itself.

Contractual penalty exclusion

Contractual penalty exclusion is the most contested wording element on metro and elevated highway PPP placements in 2026. The exclusion typically reads: the policy does not respond to penalties, liquidated damages, or contractual fines payable by the insured to the project owner under the construction contract.

The issue arises because metro and elevated highway PPP contracts typically include substantial liquidated damages for delayed completion. The LDs can run into hundreds of crore for major project delays. When the delay is caused by insured Section I damage, the contractor faces the LDs alongside the Section I and ALOP recovery, with the LDs potentially excluded from the CAR cover.

The negotiation point is whether LDs payable by the contractor to the project owner fall within the policy's general financial loss exclusion or whether they fall within a specific contractual penalty exclusion. The 2026 placement practice typically carves out LDs from the financial loss exclusion to the extent that they are payable as a direct consequence of insured Section I damage, with the LDs treated as part of the consequential loss recoverable under ALOP.

Other surveyor-flagged exclusions

1. Earth subsidence and ground heave exclusions are sometimes added on projects with elevated geotechnical risk. The exclusion limits cover for tunnel collapses and station box failures arising from ground movement.
2. Pre-existing defect exclusions exclude damage arising from defects existing in the works before the policy inception. The exclusion is enforced through pre-placement engineering survey documentation.
3. Cyber exclusions explicitly exclude damage arising from cyber events affecting the construction equipment or the project management systems. The exclusion responds to the growing exposure from cyber-induced equipment damage and the malware risk to construction-site control systems.

The Mumbai Metropolitan Region Development Authority (MMRDA) and the National Highways Authority of India (NHAI) maintain insurance specifications that define the cover the contractor must place on the project. The specifications drive the contractor's CAR programme structure and the placement requirements for participating insurers. The 2026 versions of these specifications reflect the market position and incorporate lessons from recent loss experience.

MMRDA insurance specifications for metro and infrastructure projects

The MMRDA specifications for metro and elevated infrastructure projects in 2026 require CAR cover with the following structure.

1. Section I sum insured equal to the full contract value plus 15 to 25 percent escalation cover.
2. Section II limit of INR 50 to 200 crore per occurrence depending on project urban density and proximity to third-party property.
3. ALOP cover with sum insured matching the project's planned first-year revenue and indemnity period of 18 to 24 months.
4. Cross-liability between the principal (MMRDA), the contractors, the subcontractors, and the consultants.
5. Maintenance period extension of 12 to 24 months.
6. Removal of debris cover at 10 to 15 percent of Section I sum insured.
7. Professional fees cover for restoration design and supervision.
8. Cover for hot work, blasting, piling, and tunnelling activities without restrictive exclusions.

The specifications also require the contractor to provide evidence of insurance placement at contract award and to maintain the cover throughout the construction and maintenance periods. The contractor must give MMRDA prior notice of any policy cancellation, lapse, or material amendment.

NHAI insurance specifications for highway and elevated road PPP projects

The NHAI specifications for highway PPP projects in 2026 require CAR cover with similar structure to MMRDA but with adjustments reflecting the highway-specific exposure pattern.

1. Section I sum insured equal to the full project cost plus escalation cover.
2. Section II limit of INR 25 to 100 crore per occurrence, with higher limits required for projects through populated areas.
3. ALOP cover with sum insured matching the project's planned annual toll revenue or annuity payment.
4. Cross-liability between NHAI, the concessionaire, the EPC contractor, and subcontractors.
5. Maintenance period extension of 12 months.
6. Removal of debris cover at 5 to 10 percent of Section I sum insured.
7. Cover for piling, deep excavation, and elevated structural work.

The NHAI specifications also require evidence of insurance at contract award, with regular renewal evidence through the construction period and the maintenance period.

Compliance and dispute patterns

The 2026 enforcement of insurance specifications has tightened with the project authorities reviewing the contractor's CAR programme more carefully at contract award and during execution. The specific compliance points that have produced dispute include: ALOP placement scope and limit adequacy, Section II limit adequacy for urban projects, design-defect wording (LEG 1 versus LEG 2 versus LEG 3), and the maintenance-period cover scope.

For contractors, the practical advice is to engage with the project authority's insurance team at contract award to confirm specification compliance and to address any gaps before construction commences. Disputes during execution are materially more difficult to resolve than disputes at placement.

State metro authority specifications

Beyond MMRDA and NHAI, multiple state metro authorities maintain insurance specifications including Delhi Metro Rail Corporation (DMRC), Chennai Metro Rail Limited (CMRL), Bangalore Metro Rail Corporation (BMRCL), Hyderabad Metro Rail Limited (HMRL), Kochi Metro Rail Limited (KMRL), Kolkata Metro Rail Corporation, and the various developing metro authorities in tier-2 cities. The specifications broadly track the MMRDA structure with local adjustments for the city's specific geotechnical and urban-density profile.

The 2022 to 2025 period produced multiple high-profile losses on Indian metro and elevated highway projects that have shaped the 2026 underwriting position. The loss patterns below illustrate the exposure rather than exhausting the list.

TBM jam and rescue tunnel construction

Tunnel Boring Machine jams on metro projects produce some of the highest single-event claim costs in Indian CAR experience. The TBM may become stuck in difficult ground conditions, with rescue requiring construction of a rescue shaft from the surface, dismantling of the TBM in-situ, and resumption with a replacement TBM or repaired equipment. The total claim cost (material damage to TBM, rescue tunnel cost, schedule delay leading to ALOP) can exceed INR 200 crore on a single event.

The 2023 to 2024 period saw multiple TBM-related claims on Bengaluru metro, Chennai metro Phase 2, Mumbai metro lines 3 and 4, and Delhi metro Phase 4 projects. The cumulative claims experience drove the 2026 underwriting tightening on TBM-intensive metro packages, with explicit underwriting reviews of the geotechnical investigation quality, the TBM selection appropriateness for the ground conditions, and the contractor's TBM operating expertise.

Launching girder failures on elevated viaducts

Launching girder failures on segmental elevated viaduct construction have produced repeat losses through 2022 to 2025 on multiple metro and elevated highway projects. The failure mode typically involves either a girder structural failure (overstressing of the launching girder) or a launching operation incident (loss of stability, hydraulic system failure, control system error). The consequential damage to placed segments, partially-constructed piers, and adjacent infrastructure can be material.

The 2026 underwriting position on elevated viaduct construction requires detailed pre-placement diligence on the launching girder design verification, the contractor's launching experience, and the operating procedures.

Formwork collapse during deck pour

Formwork collapse during concrete pour on elevated structures has produced multiple losses through 2022 to 2025 on elevated highway PPP projects. The failure mode typically involves either formwork design inadequacy, formwork installation defect, or concrete-pour loading exceeding design assumptions. The damage typically includes loss of the placed concrete, damage to the formwork system, and consequential damage to the supporting structure.

The 2026 underwriting position requires evidence of formwork design verification by an independent engineer for major elevated structures, with specific attention to the concrete pour sequencing and the formwork loading assumptions.

Station box excavation collapse

Metro station box excavation collapses, while less frequent than TBM events, produce material claims when they occur. The failure mode typically involves either ground movement beyond the design assumption or temporary works inadequacy. The consequential damage can include damage to adjacent property, utility disruption, and project delay.

The 2026 underwriting position requires detailed geotechnical investigation evidence, temporary works design verification, and ground monitoring during excavation.

Third-party utility damage

Third-party utility damage during construction is the most frequent loss type on Indian metro and elevated highway projects. The losses typically involve damage to underground utilities (water, sewer, gas, telecommunications, electricity) during excavation, with the damage producing direct repair cost plus consequential losses to utility customers. The Section II cover responds to these losses but the consequential business interruption to commercial customers can produce extended dispute and exceed standard Section II limits.

The 2026 market response and broker positioning

The Indian CAR market response to the recent loss patterns includes tightened underwriting at placement, expanded use of engineering surveys at the design stage rather than only at construction stage, selective declines on the highest-exposure individual projects, higher retention requirements, and explicit risk improvement requirements at placement.

For brokers placing metro and elevated highway CAR covers in 2026, the practical positioning is to engage with the contractor's engineering and project management teams well before placement, to address risk improvement commitments at the underwriting submission, to negotiate carefully on LEG wordings and contractual penalty carve-outs, and to maintain active engagement with the contractor during construction so that issues emerging during execution are addressed before they become claim disputes. The 2026 market rewards documented risk management and active broker engagement; it penalises transactional placements treated as paper compliance with the project authority specifications.
