3.3 Construction Insurance & Surety Bonds

Key Takeaways

  • Commercial General Liability (CGL) occurrence policies cover bodily injury and property damage occurring during the policy term, whereas claims-made policies cover claims reported while the policy remains active.
  • Virginia law mandates Workers' Compensation coverage for any employer who regularly employs three or more full-time or part-time workers, including working subcontractors and business officers.
  • A surety bond is a tripartite agreement between Principal (contractor), Obligee (owner), and Surety (guarantor), requiring full contractor indemnification back to the surety for any claim payouts.
  • Under the Virginia Little Miller Act, public construction contracts exceeding statutory monetary limits must require both performance and payment bonds to protect public funds and lower-tier subcontractors.

Managing risk in construction requires a comprehensive risk management program integrating commercial insurance policies and surety bonds. While both financial instruments mitigate project risk, insurance protects against unforeseen accidental losses, whereas surety bonds guarantee contractual performance and payment obligations.

Commercial Construction Insurance Coverage

Construction contractors must maintain specialized insurance coverages to protect against property damage, personal injury, and statutory liabilities.

Commercial General Liability (CGL)

Commercial General Liability (CGL) insurance protects the contractor against third-party claims for bodily injury, property damage, and personal/advertising injury arising from ongoing or completed operations.

  • Occurrence Policy: Covers bodily injury or property damage that occurs during the policy period, regardless of when the actual lawsuit or claim is filed. An occurrence policy provides long-tail protection even after policy expiration if the loss occurred while the policy was active.
  • Claims-Made Policy: Covers claims only if the incident occurs after a specified "retroactive date" AND the claim is formally reported to the insurer while the policy remains continuously active (or during an extended reporting period).

Crucial Exclusion: Standard CGL policies generally exclude coverage for repairing or replacing the contractor's own defective work product (faulty workmanship). However, if defective work causes secondary third-party property damage or bodily injury, CGL covers the resulting consequential damage.

Workers' Compensation Insurance

Under the Virginia Workers' Compensation Act (Va. Code § 65.2-100 et seq.), any employer who regularly employs three or more full-time or part-time employees (including working subcontractors, corporate officers, and LLC members) is statutorily required to maintain Workers' Compensation insurance. Workers' Comp provides no-fault coverage for employee medical expenses, temporary disability income, permanent impairment benefits, and death benefits for job-related injuries or occupational diseases. Subcontractors without insurance count toward the general contractor's threshold, exposing the general contractor to statutory employer liability.

Builders Risk & Umbrella Coverages

  • Builders Risk Insurance: A specialized property policy covering buildings and structures under construction against direct physical loss from perils such as fire, lightning, windstorm, theft, and vandalism. Coverage extends to building materials on-site, in transit, or stored at temporary locations.
  • Umbrella / Excess Liability Insurance: Provides higher financial liability limits positioned above primary underlying policies (CGL, Commercial Auto, and Employers Liability), protecting against catastrophic multi-million dollar third-party claims.

Surety Bonds & The Tripartite Agreement

Unlike insurance, which is a two-party risk-transfer contract between an insured and an insurer, a Surety Bond is a tripartite (three-party) credit agreement guaranteeing contract performance.

The Three Parties to a Surety Bond

  1. Principal: The party obligated to perform the work (typically the general contractor). The principal pays the bond premium and must execute a legal Indemnity Agreement.
  2. Obligee: The party protected by the bond (typically the project owner or public agency). If the principal defaults, the obligee collects against the bond.
  3. Surety: The licensed financial institution or bonding company that guarantees the principal's performance and financial obligations to the obligee.

Insurance vs. Surety Bonds

Under insurance, the insurer assumes the financial risk of loss and does not seek reimbursement from the policyholder for covered losses. Under a surety bond, the surety expects zero loss; if the surety pays out a claim due to contractor default, the Principal must fully indemnify and reimburse the surety for all loss payouts, legal fees, and administrative expenses.


Primary Types of Construction Surety Bonds

Surety bonds are categorized based on the specific project phase and obligation guaranteed.

Surety Bond TypeCore Purpose & ProtectionTypical Amount / Statutory Rule
Bid BondGuarantees the bidder will execute the contract and submit required performance/payment bonds if awarded.5% to 10% of total bid amount.
Performance BondGuarantees project completion according to contract plans and specifications if contractor defaults.100% of contract price.
Payment BondGuarantees payment to subcontractors, laborers, and material suppliers, keeping project lien-free.100% of contract price. Mandatory on public works.
Maintenance BondGuarantees correction of defective materials or workmanship during the post-completion warranty period.10% to 100% of contract value (1-2 years).

The Virginia Little Miller Act

Under the Virginia Little Miller Act (Va. Code § 2.2-4337), for public construction contracts exceeding statutory thresholds (typically $500,000 for state public contracts and $100,000 for local government public contracts), the prime contractor must provide executed Performance Bonds and Payment Bonds in an amount equal to 100% of the contract price.

Payment bonds are particularly vital on public projects because mechanics liens cannot be placed on government-owned public property. The payment bond provides an essential statutory remedy for unpaid subcontractors and suppliers.

Surety Remedies Upon Contractor Default

If a general contractor defaults on a bonded performance agreement, the surety possesses four standard options to satisfy its obligation to the obligee:

  1. Financially support the Principal: Provide financial assistance to the existing contractor to cure the default and complete the project.
  2. Take over and Complete: Assume direct control of the project, hiring a replacement contractor to finish the work.
  3. Tender a Replacement Contractor: Solicit bids, select a qualified replacement contractor acceptable to the owner, and pay the difference in cost.
  4. Cash Settlement: Pay the obligee the full penal sum of the bond or the actual cost of completion, whichever is less.
