Subcontractor Default Insurance (SDI)
General contractors and construction managers rely on subcontractors for specialized work. When a subcontractor fails to perform, becomes insolvent, or otherwise defaults, the result can be schedule disruption, added completion cost, and significant downstream financial impact.
Subcontractor Default Insurance (SDI) is a first-party insurance policy purchased by a general contractor or construction manager to help manage the financial consequences of subcontractor and supplier default, while allowing the contractor to maintain control over the mitigation and completion strategy.
What is Subcontractor Default Insurance (SDI)?
SDI is an insurance contract between the insured contractor and the insurer. It indemnifies the contractor for a covered loss resulting from default by covered (often enrolled) subcontractors, subject to the policy’s definition of default, notice requirements, and the contractor’s obligation to mitigate loss.
Coverage varies by carrier and program design, but SDI commonly responds to:
- Completion and replacement costs to finish the defaulted scope (including the cost to replace the subcontractor and complete remaining work).
- Investigation, legal, and dispute costs associated with managing and resolving a covered default (within policy terms).
- Certain indirect costs that result from a covered default (may include acceleration, extended overhead, and in some cases liquidated damages), when included by the policy wording and subject to conditions and sublimits.
Important: SDI is commonly structured with a self-insured retention/deductible and may include a coinsurance/copay layer, meaning the contractor retains part of the loss.
SDI Program Features
Direct Default Coverage
Reimburses expenses directly related to the default, such as hiring new subcontractors to complete unfinished work or correcting defective workmanship.
Delay-Related Costs Coverage
Covers financial losses due to project delays caused by the subcontractor’s non-performance, including penalties or liquidated damages imposed by project owners.
Administrative and Legal Expenses Coverage
Pays for costs associated with managing and resolving the default, such as legal fees, mediation, or arbitration expenses.
Cost Escalation Coverage
Addresses increased expenses for completing work at higher rates due to a subcontractor’s failure, particularly in cases of market rate fluctuations.
Extended Project Overhead Coverage
Compensates contractors for prolonged general and administrative costs incurred during extended project timelines caused by the default.
Multi-Project Coverage
Extends coverage across multiple projects under a single policy, provided the subcontractors meet prequalification criteria.
Why Would I Need SDI?
Risk Mitigation
Protects contractors from substantial financial losses caused by subcontractor defaults, including non-performance or insolvency.
Project Continuity
Ensures construction projects proceed without major disruptions or delays due to subcontractor failures.
Financial Protection
Covers costs that may not be recoverable through other means, such as surety bonds or warranties.
Control Over Resolution
Grants the contractor greater autonomy in managing the resolution process, allowing them to hire replacement subcontractors and avoid lengthy bond claim processes.
Benefits of SDI
Comprehensive Coverage
Addresses both direct and indirect costs, including legal fees, project delays, and corrective work.
Enhanced Prequalification Processes
Encourages contractors to adopt rigorous prequalification standards, reducing the likelihood of defaults.
Financial Stability
Safeguards profit margins and ensures project budgets remain intact, even in the face of subcontractor failures.
Frequently Asked Questions
- SDI is a two-party, first-party insurance policy that reimburses the contractor for covered loss caused by subcontractor default.
- Surety bonds are three-party instruments (principal, Obligee, surety). A bond responds to the Obligee (for example, an owner on a GC bond, or a GC on a subcontractor bond) under the bond terms.
- SDI generally does not provide the same third-party beneficiary protection that an Obligee receives under a bond, and it typically does not replace payment protection concepts the way labor and material payment bonds do.
Typically, SDI is purchased by large general contractors with significant annual subcontract volumes, robust risk management systems, and established prequalification processes.
SDI covers expenses such as completion costs, legal fees, correcting defective work, extended overhead, and expenses related to project delays.
Yes, most SDI policies include a deductible or self-insured retention amount that the contractor must pay before the policy responds.
Premiums are determined based on factors such as the contractor’s annual subcontract volume, historical loss data, financial stability, and risk management practices.
Eligibility typically requires contractors to demonstrate strong financial health, effective subcontractor prequalification systems, and sound risk management protocols.
Yes, SDI policies can be structured to cover all eligible subcontracts under the contractor’s portfolio during the policy term.
Design errors are generally excluded unless the subcontractor was specifically contracted to provide design services and this coverage is explicitly included in the policy.
Notify your insurer as soon as a potential default is identified. Document all related costs, such as legal expenses and project delays, and follow the insurer’s claims process for resolution. If you are a Stanhope Simpson client, please contact your representative immediately.
