Certificate of Insurance Tracking for Construction General Contractors
Construction GCs operate the highest-stakes COI tracking program in any industry. The combination of multi-tier subcontractor relationships, OSHA-regulated work, OCIP/CCIP wrap-up policies, and large project budgets means a single uninsured sub on a single bad day can turn a $5M project into a $50M lawsuit.
Most GC teams know this in theory. In practice, somewhere between 50 and 70 percent of the COIs collected from subs are non-compliant on first receipt — wrong limits, missing endorsements, wrong Additional Insured language. The gap between "we have a COI on file" and "we are actually covered" is where the failure happens.

The endorsements that actually matter
A COI is just a summary. The endorsements attached are the legal coverage. For a typical GC requiring its subs to name the GC as Additional Insured, you need:
Required endorsements per subcontract
- ✓
CG 20 10 (or equivalent) — Additional Insured for ongoing operations
- ✓
CG 20 37 — Additional Insured for completed operations
- ✓
CG 24 04 — Waiver of subrogation
- ✓
CG 20 01 — Primary and non-contributory
- ✓
Workers' Compensation waiver of subrogation
- ✓
Auto liability AI endorsement where the sub operates vehicles
⚠️The most common COI failure: the GC is listed as Certificate Holder, but no Additional Insured endorsement form is attached. Certificate Holder gives you no rights under the policy. Always request the endorsement form, not just the certificate page.
The contract-to-pay COI gate
The most effective enforcement is making COI compliance a precondition of two things every subcontractor cares about:
The two-gate model
- ✓
Gate 1: Subcontract execution — no fully executed sub-K until COI + endorsements are validated and on file
- ✓
Gate 2: Pay app release — no payment processed if COI has lapsed or fails monthly status check
Subs do not chase compliance for compliance's sake. They chase it because their pay app is held. The discipline shifts when the consequence is immediate and financial.
OCIP / CCIP wrap-up interactions
On wrap-up projects, the owner or GC provides general liability and excess coverage for all enrolled subs. That changes the COI requirement — but does not eliminate it. Subs still need:
OCIP/CCIP-enrolled sub COI requirements
- ✓
Workers' Compensation (most wrap-ups exclude WC — sub still needs theirs)
- ✓
Auto liability (almost always excluded from wrap-ups)
- ✓
Excess where the wrap-up limits are insufficient for high-risk trades
- ✓
Off-site / pre-mobilisation coverage during enrolment lag
- ✓
Wrap-up enrolment certificate itself (proof they are enrolled)
💡 Pro Tip
The enrolment-lag risk is real: a sub starts work before their wrap-up enrolment is complete. The gap between mobilisation and enrolment is uncovered. Build a "pre-enrolment" status into your COI workflow with its own gating.
The multi-tier flow-down problem
Your sub hires a sub-sub. Your sub-sub hires a sub-sub-sub. Each tier should have a flow-down clause requiring the same insurance terms — but few GCs verify beyond the first tier. The result: a sub-sub-sub working on your site with no Additional Insured relationship to you at all.
The fix is policy and proof: require every sub to evidence their lower-tier subs' insurance to the same standard. Audit a random 10% sample per project.
Mid-policy cancellation — the silent failure mode
Most policies can be cancelled mid-term. The COI you received in January may be void by March. Mitigations:
Mid-cancellation mitigations
- ✓
Require CG 24 04 (notice of cancellation to AI) on every policy
- ✓
Run continuous status verification, not just expiry checks
- ✓
Tag any policy with high-claim history for closer monitoring
- ✓
Treat any received "policy cancelled" notice as a hard pay-app stop
The five-question pre-mobilisation COI checklist
For every sub before they roll a truck onto site:
Pre-mobilisation COI checklist
- ✓
1. Is the named insured exactly the entity in the subcontract?
- ✓
2. Are policy limits ≥ contract minimums (GL, AL, WC, Excess)?
- ✓
3. Is your entity named Additional Insured on the endorsement form (not just Cert Holder)?
- ✓
4. Are CG 20 10 and CG 20 37 both attached?
- ✓
5. Is the policy in force on the project mobilisation date?
✅If all five answers are yes, the sub can mobilise. If any is no, the sub is held — gate 1 of the contract-to-pay model.
Build, buy, or hybrid
Enterprise GCs with >500 active subs typically need TrustLayer, myCOI, Billy, or Constrafor — purpose-built CRE/construction COI platforms with bidirectional sub portals and dedicated COI ops teams. Pricing tracks usage and is rarely under $30k a year.
Mid-market GCs (25–500 active subs) often find these platforms over-engineered. ExpiryEdge handles the COI-tracking layer at a fraction of the cost — document collection, validation, expiry monitoring, contract-to-pay gating, audit trail — without the bidirectional sub portal complexity. Most mid-market GCs adopt ExpiryEdge alongside their primary project-management platform (Procore, PlanGrid) rather than replacing it.
Where this goes wrong, and how to recover
1. You inherited a portfolio with stale COIs
Do not try to fix it all at once. Phase it: priority 1 is any sub on an active site; priority 2 is any sub on an upcoming site; priority 3 is the historical backlog. Most operators reach defensibility within a single project cycle.
2. A sub refuses to provide the endorsement form
Two paths: (a) escalate to their broker — brokers know endorsement forms exist and can usually produce them in a day; (b) the contract specifies the requirement, so non-compliance is breach. Most subs resolve once they realise the broker call is faster than the legal call.
3. The wrap-up paperwork is incomplete
OCIP / CCIP administration is its own discipline. If your wrap-up administrator is slow, get in front of them: enrolment status report weekly until every sub on the project is enrolled.
