Section 5.3: Risk Assessment, Subcontractor Certificates & Indemnification

Key Takeaways

  • General contractors must verify subcontractor insurance using ACORD Certificates of Insurance (COI) and enforce mandatory coverage limits prior to jobsite entry.
  • Naming the general contractor as an 'Additional Insured' on the subcontractor's CGL policy grants direct defense and indemnity coverage on a primary and non-contributory basis.
  • Minnesota Anti-Indemnification Statute (Minn. Stat. § 337.02) voids broad-form indemnity clauses that attempt to force a subcontractor to indemnify a general contractor for the GC's own negligence.
  • Builder's Risk Insurance provides specialized property coverage for structures, building materials, and fixtures during construction against covered physical perils such as fire, wind, and vandalism.

Risk Assessment, Subcontractor Certificates & Indemnification

General contractors on residential and commercial projects operate as the central hub of project risk management. A primary contractor assumes ultimate accountability for jobsite safety, structural integrity, and financial performance. Managing downstream risk requires robust risk-transfer protocols, strict verification of subcontractor Certificates of Insurance (COI), compliant Additional Insured endorsements, adherence to Minnesota’s Anti-Indemnification Statute (Minn. Stat. § 337.02), and comprehensive Builder's Risk property insurance. This section details contract risk management strategies, statutory limitations on hold harmless agreements, and course-of-construction property protection.


1. Subcontractor Risk Management & Certificate of Insurance (COI) Verification

General contractors frequently delegate specialized trades (electrical, plumbing, masonry, roofing) to subcontractors. However, if a subcontractor lacks adequate insurance, injured workers or third-party property owners can seek financial recovery directly from the general contractor.

Verification of the ACORD 25 Certificate of Insurance

Before permitting any subcontractor to commence work or step onto a jobsite, the general contractor must collect and verify a standardized ACORD 25 Certificate of Insurance (COI).

Essential Endorsements Required from Subcontractors

Collecting a simple COI is insufficient because a COI is merely an informational document that does not amend or alter underlying insurance contracts. General contractors must mandate specific policy endorsements:

  1. Additional Insured Status:
    • The subcontractor’s CGL policy must be amended by endorsement (such as ISO forms CG 20 10 for ongoing operations and CG 20 37 for completed operations) naming the General Contractor and Property Owner as Additional Insureds.
    • Legal Benefit: Provides the general contractor with direct defense and indemnification under the subcontractor's policy if a lawsuit arises out of the sub's work.
  2. Primary and Non-Contributory Clause:
    • Mandates that the subcontractor's CGL policy must respond on a primary basis (pays first) and will not seek contribution from the general contractor's own CGL policy.
  3. Waiver of Subrogation:
    • The subcontractor's insurance carrier waives its right to sue ("subrogate against") the general contractor to recover claim payments made under the subcontractor's CGL or Workers' Compensation policies.

2. Indemnification Agreements & Minnesota Anti-Indemnification Law (Minn. Stat. § 337.02)

In construction subcontracts, an Indemnification Clause (also known as a Hold Harmless Clause) is a contractual provision where one party (the indemnitor / subcontractor) agrees to compensate and defend another party (the indemnitee / general contractor) against legal liabilities, lawsuits, and financial losses.

Tiers of Indemnification Clauses

Historically, indemnity agreements were categorized into three legal forms based on risk allocation:

  • Broad Form Indemnity: Requires the subcontractor to indemnify the general contractor for ALL losses, even if the loss was caused solely by the general contractor's own negligence.
  • Intermediate Form Indemnity: Requires the subcontractor to indemnify the general contractor for losses if both parties are partially at fault, but excludes coverage if the GC is solely at fault.
  • Limited Form Indemnity: Requires the subcontractor to indemnify the general contractor ONLY to the extent of the subcontractor’s own negligence or fault.

Minnesota Anti-Indemnification Statute (Minn. Stat. § 337.02)

To prevent powerful general contractors from forcing subcontractors to insure risks over which they have no control, the Minnesota Legislature enacted Minn. Stat. § 337.02, known as the Minnesota Anti-Indemnification Statute.

│  Any provision in a building and construction contract that requires     │

│  another party (general contractor) for injury or damage caused by the    │
│  NEGLIGENCE OR FAULT of the promisee (GC) is NULL AND VOID.              │
└──────────────────────────────────────────────────────────────────────────┘

Legal Impact & Exceptions

  1. Void Provisions: Under Minn. Stat. § 337.02, any subcontract clause attempting to create Broad Form or broad Intermediate Form indemnity requiring a sub to hold a GC harmless for the GC's own negligence is unenforceable and void under Minnesota law.
  2. Permitted Risk Allocation: Subcontracts in Minnesota can only enforce Limited Form Indemnity—holding the GC harmless for damages caused by the subcontractor's own negligence or fault.
  3. Statutory Exceptions (Minn. Stat. § 337.05):
    • Insurance Purchase Agreements: Minn. Stat. § 337.02 does not invalidate agreements where a party promises to purchase specific insurance coverage for the project (such as naming the GC as an Additional Insured).
    • Owner/Contractor Protective Policies (OCIP / CCIP): Project "wrap-up" insurance policies are fully exempt from anti-indemnification restrictions.

3. Builder's Risk Insurance (Course of Construction Coverage)

While CGL insurance covers third-party liability (injury to outsiders or damage to outside property), Builder's Risk Insurance is a specialized first-party property policy that protects the physical building, structures, and materials while under construction.

Key Policy Features & Valuation Bases

  • Named Insureds: A Builder's Risk policy should list the Property Owner, General Contractor, and all Subcontractors as named or additional named insureds to prevent internal subrogation claims if a fire or accident occurs.
  • Policy Valuation Formats:
    1. Completed Value Form: The policy limit is set at 100% of the anticipated final completed value of the structure from day one. Premiums are paid upfront or in installments based on full value.
    2. Reporting Form: The contractor files monthly reports updating the actual value of work completed to date, and premiums adjust dynamically as construction progresses.

Standard Exclusions in Builder's Risk Policies

Builder's Risk policies contain specific exclusions that contractors must manage through specialized endorsements:

5. Exam Focus Scenario & Analysis

Scenario: A Minnesota general contractor inserts a clause in a framing subcontract stating: "Subcontractor agrees to defend, indemnify, and hold harmless General Contractor from any and all claims, injuries, or property damage occurring on the jobsite, including claims caused by General Contractor's own negligence." During construction, a crane operated solely by the General Contractor drops a steel beam, injuring a framing sub employee.

Legal Analysis:

  1. Statutory Voidance: Under Minn. Stat. § 337.02, the broad-form indemnification clause attempting to force the subcontractor to indemnify the GC for the GC's own negligence is null, void, and unenforceable.
  2. Liability Outcome: The General Contractor cannot pass liability to the subcontractor and remains legally liable for injuries caused by its own negligent crane operation.
