The Subcontractor Risk Challenge
General contractors face significant exposure when subcontractors fail to perform. Whether due to bankruptcy, abandonment, or quality issues, subcontractor default can devastate project timelines and budgets. Two primary risk transfer mechanisms exist: traditional surety bonds and Subcontractor Default Insurance (SDI).
Understanding Surety Bonds
How They Work:
- Subcontractor purchases a performance and payment bond
- Surety guarantees subcontractor's performance
- If sub defaults, surety steps in to complete work or pay damages
- Three-party agreement: Principal (sub), Obligee (GC), Surety
Advantages:
- No cost to the general contractor
- Pre-qualification of subcontractors through surety underwriting
- Payment bond protects against mechanic's liens
- Well-established legal framework
Disadvantages:
- Many subs can't obtain bonding
- Limits your subcontractor pool
- Surety claims process can be slow
- Surety may dispute claims
Understanding Subcontractor Default Insurance
How It Works:
- General contractor purchases the policy
- Covers losses from subcontractor default
- First-party insurance (GC is the insured)
- Coverage typically includes completion costs, delay damages, and related expenses
Advantages:
- Faster claims resolution (no adversarial surety relationship)
- Broader subcontractor pool (bondability not required)
- More control over completion strategy
- Can cover soft costs and delay damages
Disadvantages:
- GC pays premium (typically 0.5%-1.0% of subcontracted work)
- Significant deductibles and co-insurance
- Requires robust subcontractor prequalification program
- No payment bond protection for lower-tier subs
When SDI Makes Sense
Large Project Volume
SDI becomes cost-effective when you have:
- Annual subcontracted volume over $50 million
- Multiple projects running simultaneously
- In-house capability to manage defaults
Desire for Broader Subcontractor Access
When you need to work with:
- Emerging subcontractors with limited bonding capacity
- Specialty trades where bonded subs are scarce
- Subcontractors recovering from financial difficulties
Control Over Default Response
When you want to:
- Manage completion without surety interference
- Make quick decisions on remediation
- Control the completion contractor selection
When Bonding Is Better
Smaller Contractors
Traditional bonding may be preferable if you:
- Have less than $50 million in annual subcontracted work
- Don't have robust prequalification capabilities
- Need payment bond protection
Public Work
Many public projects:
- Require traditional surety bonds by law
- Have specific bonding requirements in contracts
- Won't accept SDI as an alternative
Single Large Projects
For individual large projects:
- Project-specific bonds may be more cost-effective
- Owner may require traditional bonding
- Risk concentration makes SDI pricing unfavorable
Implementing an SDI Program
Step 1: Subcontractor Prequalification
SDI carriers require rigorous prequalification:
- Financial statement analysis
- Banking and trade references
- Project history review
- Management team evaluation
- Safety record assessment
Step 2: Program Structure
Typical SDI program elements:
- Annual aggregate limits based on subcontracted volume
- Per-subcontractor limits based on contract size
- Deductibles ranging from $250,000 to $1,000,000
- Co-insurance of 10%-20%
Step 3: Ongoing Administration
SDI requires continuous management:
- Regular subcontractor monitoring
- Updated financial information
- Early warning system for troubled subs
- Documentation of default events

Making the Decision
The right choice depends on:
- Your project volume and type
- Subcontractor market conditions
- Internal prequalification capabilities
- Risk tolerance and cash flow
- Owner and lender requirements
