6.1 Commercial General Liability, Builders Risk & Property Coverage

Commercial General Liability (CGL): Core Architecture and Triggers

Commercial General Liability (CGL) insurance serves as the foundational risk-transfer instrument protecting general contractors and construction managers against catastrophic third-party liabilities arising from jobsite operations. Standard commercial construction policies are built upon policy forms developed by the Insurance Services Office (ISO), most notably the ISO Form CG 00 01.

Occurrence-Based vs. Claims-Made Policy Triggers

A critical distinction on the South Carolina contractor licensing examination is the operational mechanism governing how insurance coverage is triggered:

Key Principle — Latent Construction Defects: If a general contractor holds an occurrence-based CGL policy from January 1, 2024, through December 31, 2024, and improperly installed plumbing causes a pipe fitting to burst on November 15, 2024, the 2024 policy responds to the claim even if the building owner does not discover the resulting wall cavity mold and file suit until June 2026.

Primary CGL Coverage Parts

The standard ISO commercial general liability policy contains three distinct coverage sections:

1. Coverage A: Bodily Injury and Property Damage Liability

Coverage A obligates the insurer to pay those sums that the insured becomes legally obligated to pay as damages because of 'bodily injury' or 'property damage' caused by an occurrence within the 'coverage territory.'

• Bodily Injury: Physical injury, sickness, disease, or resulting death sustained by third parties (e.g., a delivery driver struck by falling scaffolding on the jobsite).
• Property Damage: Physical injury to tangible property, including all resulting loss of use of that property, or loss of use of tangible property that is not physically injured.
• Definition of an Occurrence: Under ISO terms, an occurrence is defined as 'an accident, including continuous or repeated exposure to substantially the same general harmful conditions.' Intentional, fraudulent, or knowingly substandard work is not accidental and therefore does not qualify as an occurrence.

2. Coverage B: Personal and Advertising Injury Liability

Protects against specific intentional legal torts arising out of the contractor's business operations (excluding bodily injury and tangible property damage). Covered offenses include:

• False arrest, detention, or wrongful imprisonment
• Malicious prosecution
• Wrongful eviction from, wrongful entry into, or invasion of the right of private occupancy
• Oral or written publication of material that slanders or libels a person or organization, or disparages goods/services
• Oral or written publication of material that violates a person's right of privacy
• Infringing upon another's copyright, trade dress, or slogan in commercial advertising

3. Coverage C: Medical Payments

Provides direct, no-fault reimbursement for reasonable medical, surgical, ambulance, hospital, and funeral expenses incurred by third parties injured on the contractor's premises or jobsite. Because Coverage C does not require proof of legal negligence or fault, it acts as a prompt goodwill mechanism to settle minor injuries before they escalate into formal civil lawsuits.

Critical CGL Exclusions and the Subcontractor Exception

Commercial General Liability is not a performance bond, nor is it a warranty on the quality of construction. Insurers incorporate rigorous exclusions into Coverage A to prevent contractors from using liability insurance to subsidize poor craftsmanship.

Analysis of Key CGL Exclusions

1. Damage to Your Work (Exclusion l):

   • Excludes property damage to the insured contractor's own completed work. The policy will not pay to tear out and replace defective concrete poured by the GC's direct payroll employees.
   • The Subcontractor Exception: This exclusion explicitly states: 'This exclusion does not apply if the damaged work or the work out of which the damage arises was performed on your behalf by a subcontractor.' In modern commercial contracting, where general contractors subcontract 80% to 95% of trade scopes, this exception is the single most vital coverage bridge for completed project liabilities.

2. Damage to Impaired Property or Property Not Physically Injured (Exclusion m):

   • Excludes loss of use or economic loss to property that incorporates the contractor's defective, deficient, or delayed work, provided the property can be restored to full utility simply by repairing, replacing, or removing the contractor's work.

3. Contractual Liability Exclusion and 'Insured Contracts':

   • Excludes bodily injury or property damage for which the contractor is obligated to pay damages by reason of the assumption of liability in a contract or agreement.
   • Exception for 'Insured Contracts': Carves out broad protection for standard construction indemnity agreements where the contractor agrees under a prime contract to defend and indemnify the project owner or architect for tort liability arising from project operations.

4. Other Common Policy Exclusions:

   • Expected or Intended Injury: Precludes intentional property destruction.
   • Workers' Compensation & Employer's Liability: Worksite employee injuries are covered exclusively by Workers' Comp and Employer's Liability, never CGL.
   • Pollution: Comprehensive exclusion for hazardous chemical release, fuel leaks, and silica or asbestos discharge, unless a specialized Contractor's Pollution Liability (CPL) endorsement is secured.
   • Aircraft, Auto, or Watercraft: Precludes liability arising from vehicular accidents, which must be insured under Commercial Auto policies.

Products-Completed Operations Hazard (PCOH) and Policy Limits

Products-Completed Operations Hazard (PCOH)

The Products-Completed Operations Hazard protects the contractor against claims for bodily injury and third-party property damage that occur away from premises owned or rented by the contractor and arise out of the contractor's work after that work has been completed or put to its intended use.

A project is deemed complete under CGL terms when:

• All work called for in the contract has been completed
• All work at a specific jobsite has been completed if the contract covers multiple sites
• That portion of the work has been put to its intended use by any person or organization other than another contractor or subcontractor working on the same project

[ACTIVE PROJECT OPERATIONS]                     [PROJECT HANDOVER & OCCUPANCY]
  Ongoing Operations Coverage                     Products-Completed Operations Hazard (PCOH)
  - Worker drops hammer on pedestrian            - Foundation settles 18 months later, cracking walls
  - Crane strikes adjacent parked vehicle        - Roof flashing fails during storm, ruining server room
  - Governed by: General Aggregate Limit         - Governed by: Products-Completed Operations Aggregate Limit

Policy Limits Structure and Per-Project Endorsements

A standard commercial CGL declaration page defines multiple interrelated monetary ceilings:

1. Per-Occurrence Limit: The maximum dollar amount the insurer will pay for all damages, medical expenses, and judgments resulting from any single occurrence, regardless of the number of claimants.
2. General Aggregate Limit: The maximum total sum the insurer will pay across the entire annual policy term for all claims under Coverage A, Coverage B, and Coverage C combined (excluding Products-Completed Operations).
3. Products-Completed Operations Aggregate Limit: A completely separate, dedicated aggregate dollar limit applying to all claims arising within the completed operations hazard during the policy term.

The Danger of Standard Aggregates across Multiple Jobsites: If a general contractor manages eight ongoing commercial projects simultaneously under a single standard CGL policy with a $2,000,000 General Aggregate Limit, a major catastrophic loss of $1,800,000 on Project A exhausts virtually the entire aggregate pool, leaving the remaining seven projects with only $200,000 of liability protection for the rest of the policy year.

The Solution — Designated Construction Project(s) General Aggregate Limit (ISO Form CG 25 03): To prevent cross-project aggregate erosion, South Carolina general contractors must require a Per-Project Aggregate Endorsement. This endorsement modifies the policy so that the full General Aggregate Limit applies separately and independently to each distinct construction project.

Builders Risk Insurance: First-Party Physical Damage Protection

While CGL protects against third-party liability claims, Builders Risk Insurance (also known as Course of Construction insurance) is specialized first-party property insurance. It indemnifies the owner and contractor for direct physical loss or damage to the building under construction, temporary structures, and materials awaiting installation.

Under standard industry contract forms (such as AIA Document A201 General Conditions of the Contract for Construction), the project owner is typically required to purchase and maintain Builders Risk coverage for the full replacement value of the completed project. However, in many design-build and commercial contracts, this obligation is contractually transferred to the general contractor.

Builders Risk Policy Forms and Covered Property

Scope of Covered Property

• The physical foundation, structural framing, exterior envelope, mechanical systems, and finishes of the building under construction
• Construction materials, supplies, and fixtures located on the designated jobsite
• Materials in transit to the project jobsite (requires specific transit sublimit endorsement)
• Materials and fabricated assemblies stored off-site at secondary warehouses or pre-casting yards (requires off-site storage sublimit)
• Temporary jobsite structures, scaffolding, site fencing, cribbing, and formwork (when endorsed)

Standard Builders Risk Exclusions and London Engineering Group (LEG) Clauses

Standard commercial Builders Risk policies contain express exclusions for:

• Flood, surface water, tidal wave, storm surge, and sewer back-up (requires separate National Flood Insurance Program [NFIP] or Difference in Conditions [DIC] policies)
• Earthquake, earth movement, sinkholes, and volcanic eruption
• War, terrorism, nuclear hazard, and governmental confiscation
• Mechanical breakdown, normal wear and tear, rust, rot, and vermin
• Faulty design, defective plans, or deficient workmanship: In heavy commercial and civil construction, coverage for defective design/workmanship is governed by standardized London Engineering Group (LEG) defect clauses:
  • LEG 1/96 (Outright Exclusion): Excludes all loss or damage caused by defective design, material, or workmanship.
  • LEG 2/96 (Consequences Exclusion): Excludes the direct cost that would have been incurred to rectify the defective component immediately prior to the loss, but covers all resulting collateral physical damage to other sound portions of the project.
  • LEG 3/96 (Broad Improvement Form): Covers all resulting damage and only excludes the incremental cost incurred to improve the original design or workmanship.

Builders Risk Soft Costs Endorsements and Termination Triggers

Soft Costs (Delay in Completion) Endorsements

When an insured physical peril (such as a four-alarm jobsite fire) destroys a partially framed commercial building, physical rebuilding costs represent only a portion of the developer's total financial loss. The project schedule is inevitably delayed by six to twelve months, triggering devastating carrying costs.

A Soft Costs Endorsement (Delay in Opening / Delay in Startup coverage) reimburses the owner or contractor for critical consequential financial losses resulting directly from an insured physical delay, including:

• Additional construction loan interest incurred during the reconstruction period
• Real estate taxes, special municipal assessments, and property insurance premiums continuing during the delay
• Architectural, structural engineering, and design consultant fees required to re-plan the work
• Legal, accounting, and professional auditing fees
• Jobsite general conditions extension costs (job trailer lease, security guard services, temporary power, project superintendent salaries)
• Advertising, promotional marketing, and public relations expenses required to re-lease commercial retail or office suites
• Lost rental income or facility operating revenue resulting from delayed tenant occupancy

When Does Builders Risk Coverage Terminate?

Understanding the exact legal cessation of Builders Risk coverage is a primary exam topic. Unless an explicit extension endorsement is issued, coverage automatically terminates upon the earliest occurrence of any of the following events:

1. The policy expires or is formally cancelled
2. The project is accepted by the owner upon Substantial Completion
3. The property is occupied in whole or in part by the owner or tenants, or put to its intended commercial use (without express underwriter consent)
4. The contractor's insurable interest in the property ceases
5. The project is abandoned by the contractor with no intent to complete construction
6. The lapse of a specified period (typically 60 to 90 days) following substantial completion or partial occupancy

Additional Commercial Coverages and Risk Transfer Instruments

Beyond CGL and Builders Risk, South Carolina commercial general contractors must deploy complementary insurance and contractual risk transfer mechanisms across every project.

1. Complementary Commercial Coverages

• Inland Marine / Commercial Equipment Floater: Protects mobile contractor equipment, machinery, excavators, bulldozers, scissor lifts, generators, scaffolding, and employee hand tools that move across multiple jobsites. Standard property policies only cover fixed locations; equipment floaters provide continuous transit and jobsite coverage.
• Commercial Auto Liability: Insures contractor-owned pickup trucks, utility vans, dump trucks, and mobile flatbeds. Critical ISO coverage symbols include Symbol 1 (Any Auto) or a combination of Symbol 7 (Specifically Described Autos), Symbol 8 (Hired Autos), and Symbol 9 (Non-Owned Autos) to protect the GC when employees operate personal vehicles for jobsite supply runs.
• Commercial Umbrella and Excess Liability: Provides high-limit catastrophic coverage (e.g., $5,000,000 to $25,000,000+) structured directly over underlying CGL, Commercial Auto, and Employer's Liability policies.

2. Contractual Risk Transfer: The ACORD 25 Certificate of Insurance

The ACORD 25 Certificate of Liability Insurance is the universal document utilized in commercial contracting to provide verified evidence of a party's insurance coverage. General contractors must enforce strict COI collection protocols before any subcontractor enters the jobsite.

+--------------------------------------------------------------------------------------------------+

Exam Trap — A Certificate of Insurance Is Not a Policy: Under South Carolina law, an ACORD certificate is merely an informational memorandum. It confers no contractual rights, does not amend policy provisions, and does not guarantee coverage. The actual insurance policy, endorsements, and policy declarations control all coverage determinations. GCs must demand copies of the actual Additional Insured Endorsements (e.g., ISO CG 20 10 for ongoing operations and CG 20 37 for completed operations).

3. Additional Insured Endorsements vs. Waiver of Subrogation

• Additional Insured (AI) Endorsement: Gives the upstream party (the GC or owner) direct coverage under the subcontractor's CGL policy as an insured party for claims arising out of the subcontractor's operations. If an injured third party sues both the sub and the GC, the subcontractor's insurer is legally obligated to defend and indemnify the GC directly.
• Waiver of Subrogation: Subrogation is the legal doctrine whereby an insurer, after paying a covered claim to its policyholder, 'steps into the shoes' of the insured to sue a third party whose negligence caused the loss. A contractual Waiver of Subrogation endorsement precludes the insurer from filing a recovery lawsuit against the project owner, architect, or other project contractors. This prevents expensive multi-party litigation and keeps project risk allocated within the designated insurance program.
