Construction insurance glossary.

The terms owners and developers encounter when insuring a construction project — from completed operations to the hammer clause and land subsidence, defined plainly.

Coverage triggers and provisions

Completed Operations
Coverage for bodily injury and property damage claims arising after a construction project is finished, addressing the long-tail exposure that can attach to an owner.
Extended Completed Operations
An extension of completed-operations coverage, which on an Owner's Interest policy can run up to 10 years or the applicable statute of repose, whichever is less.
Products-Completed Operations Hazard
A defined category in a liability policy covering injury or damage arising out of the insured's completed work, away from premises the insured owns or rents.
Occurrence Policy
A policy that responds to claims arising from events that happen during the policy period, regardless of when the claim is actually made. Most construction liability is written on this basis.
Claims-Made Policy
A policy that responds only to claims first made during the policy period, in contrast to an occurrence policy. Requires attention to retroactive dates and tail coverage.
Per-Occurrence Limit
The maximum an insurer will pay for a single covered occurrence, regardless of the number of claims or claimants arising from it.
Aggregate Limit
The maximum an insurer will pay in total during the policy period, across all covered occurrences.
Self-Insured Retention (SIR)
An amount the insured pays on a covered loss before the policy responds. Unlike a deductible, the insured typically handles claims within the SIR directly.
Deductible
The portion of a covered loss the insured bears before the insurer pays, after which the insurer responds up to the applicable limit.
Named Insured
The party or parties specifically named on the policy declarations, holding the broadest rights and responsibilities under the contract.
Primary and Non-Contributory
Contract language requiring one party's coverage to respond first and without seeking contribution from another party's insurance, common in owner-contractor agreements.
Other Insurance Clause
A policy provision determining how coverage responds when more than one policy applies to the same loss, such as pro-rata sharing or excess treatment.
Duty to Defend
An insurer's obligation to provide and pay for the legal defense of a covered claim, often broader than its duty to pay a judgment.
Retroactive Date
On a claims-made policy, the date before which occurrences are not covered, limiting how far back the coverage reaches.
Tail Coverage
An extended reporting period on a claims-made policy that allows claims to be reported after the policy ends, for occurrences during the policy term.

Endorsements and clauses

Endorsement
A written amendment to a policy that adds, removes, or modifies coverage. Optional Owner's Interest coverages such as pollution and subsidence are added by endorsement, subject to appetite.
Hammer Clause
A provision that limits an insurer's exposure if the insured refuses to consent to a proposed settlement, capping the insurer's obligation at the amount it could have settled for plus defense costs to that date. A 'soft' hammer clause shares further costs on an agreed percentage basis.
Waiver of Subrogation
A provision under which an insurer gives up its right to recover a paid loss from a third party, commonly required between owners and contractors by contract.
Subrogation
An insurer's right, after paying a claim, to pursue recovery from a third party responsible for the loss.
Exclusion
A policy provision that removes certain risks, activities, or conditions from coverage. Reviewing exclusions is essential to understanding what a policy actually covers.
Residential Construction Exclusion
An exclusion, common in some contractor policies, removing coverage for residential or habitational work such as condominiums and apartments.
Contractual Liability
Coverage for liability the insured assumes under an 'insured contract,' such as an indemnity agreement, within the terms of the policy.
Cross-Suits / Cross-Liability
How a policy treats claims between insureds under the same policy. A separation-of-insureds provision generally allows the policy to apply to each insured separately.

Site, operations, and construction terms

General Contractor (GC)
The party with primary control of a construction site and the work performed there, typically responsible for hiring and coordinating subcontractors.
Subcontractor
A specialty contractor hired by the general contractor to perform a defined scope of work, such as electrical, mechanical, or demolition.
Prime Contractor
The contractor holding the primary contract with the owner, responsible for delivering the project and often engaging subcontractors.
Project Owner
The entity that commissions and holds an interest in a construction project, bearing ultimate risk and the party an Owner's Interest policy protects.
Developer
An entity that initiates and finances a project, often the owner or acting on the owner's behalf, and a common purchaser of Owner's Interest coverage.
Demolition
The dismantling or removal of existing structures, among the higher-hazard construction activities. Demolition, including demolition-only projects in progress, can be within Owner's Interest appetite with proper controls.
Tower Crane
A fixed crane used on larger construction sites for lifting heavy materials at height, a high-hazard operation that can be in appetite with verified operator insurance and safety controls.
Crane Operations
Lifting activities using mobile or tower cranes, subject to heightened underwriting scrutiny given the severity of potential losses.
Hard Costs
The direct costs of physical construction, such as labor and materials, as distinct from soft costs like design and financing.
Soft Costs
Indirect project costs such as architectural, engineering, legal, and financing fees, which may factor into overall project risk.
Substantial Completion
The point at which a project is sufficiently complete for its intended use, a milestone that can affect when completed-operations exposure begins.
Punch List
A list of remaining items to finish or correct before a project is considered complete, generated near the end of construction.

Ground and property hazards

Subsidence
Downward movement of ground supporting a structure. Subsidence coverage is available on an Owner's Interest policy by endorsement, subject to appetite.
Land Subsidence
The gradual settling or sudden sinking of the ground surface, which can result from excavation, dewatering, soil conditions, or nearby construction, and can cause damage to adjacent structures.
Earth Movement
A broad category of ground-related perils, including subsidence, settling, and shifting, often addressed through specific policy language or endorsements.
Shoring
Temporary structural support installed to prevent collapse during excavation or demolition, a key control for adjacent-property and subsidence risk.
Underpinning
Strengthening or extending the foundation of an existing structure, often required to protect neighboring buildings during adjacent construction.
Pollution Liability
Coverage for claims arising from pollution conditions, available on an Owner's Interest policy by endorsement with multiple ISO options, subject to appetite.

Insurance mechanics and documentation

Drop-Down Coverage
The ability of a policy to respond to covered losses that are uncollectible under an underlying policy, for example when the underlying limits have eroded.
Surplus Lines (E&S)
Insurance placed with a non-admitted carrier for risks that admitted carriers may not write. Surplus lines carriers generally do not participate in state guaranty funds.
Admitted Carrier
An insurer licensed by a state and subject to its rate and form regulation, whose policyholders are generally protected by the state guaranty fund.
Non-Admitted Carrier
An insurer not licensed in a given state but permitted to write certain risks through surplus-lines channels, offering flexibility for hard-to-place exposures.
Certificate of Insurance (COI)
A document evidencing that a party carries insurance, including coverage types and limits, often required from a general contractor by a project owner.
Loss Run
A report of an insured's historical claims, used by underwriters to evaluate risk and price coverage.
Underwriting
The process by which an insurer evaluates a risk to decide whether to offer coverage and on what terms, price, and conditions.
Appetite
The range of risks an insurer is willing to write. Coverages 'subject to appetite' depend on the specifics of the project meeting underwriting criteria.
Referral
An underwriting step in which a risk with certain characteristics is reviewed by a carrier before terms are offered, rather than quoted automatically.
Collateral
Security, such as a letter of credit or cash, that a program may require from a sponsor to guarantee obligations like deductibles, common in wrap-ups.
