Demolition subcontractors
Demolition subcontractor COI requirements
Demolition contractors take buildings apart next to buildings that are staying. Their policies are among the most restricted in construction: XCU exclusions, asbestos and lead exclusions, total pollution wording and adjacent property limitations. Pikorua Security's 2026 benchmark puts demolition at 81% deficient on first review, second only to roofing.

| Coverage | Typical limit | What to check |
|---|---|---|
| Commercial general liability (CG 00 01, occurrence) | $2,000,000 each occurrence / $4,000,000 general aggregate | No XCU, adjacent property or demolition-of-structures exclusion. Per-project aggregate via CG 25 03. |
| Products-completed operations aggregate | $2,000,000 | Shorter tail than structural trades, but damage to adjacent structures can surface after the sub demobilizes. |
| Business auto liability | $2,000,000 combined single limit | Roll-off and dump trucks hauling debris on public roads. |
| Umbrella / excess liability | $10,000,000 each occurrence and aggregate | Raise to $25,000,000 for urban structural demolition beside occupied buildings. |
| Workers compensation / employer's liability | Statutory / $1,000,000 each accident, $1,000,000 disease each employee, $1,000,000 disease policy limit | Demolition carries some of the highest WC rates in construction. |
| Contractors pollution liability | $5,000,000 each condition / $5,000,000 aggregate | Asbestos, lead, PCBs and mold disturbed during demolition, plus transportation of debris. |
| Contractor's equipment (inland marine) | Replacement cost of excavators, shears and processors | High-value attachments on site are a theft and damage exposure. |

Exclusion watchlist
Exclusions that void demolition coverage
- Red flag
Explosion, collapse and underground (XCU) exclusion
Carrier XCU endorsements remove collapse and explosion losses. Structural demolition is the controlled collapse of a building, and implosion work is explosion by definition.
- Red flag
Asbestos, lead and total pollution exclusions (CG 21 49)
Most CGL policies exclude asbestos and lead, and a total pollution exclusion removes the remaining carve-backs. Before demolition, federal asbestos rules require an inspection, and disturbed materials are a pollution claim unless a CPL policy responds.
- Red flag
Adjacent property or damage to existing structures exclusion
Carrier forms that exclude damage to buildings next to the work. For a demolition contractor, the neighboring building is the primary third-party property exposure.
- Red flag
CG 21 53 Designated ongoing operations (implosion, blasting)
Carriers may schedule blasting, implosion or structural demolition above a stated height out of the policy. A general demolition policy may not cover the method your project uses.
Why demolition COIs fail so often
Carriers that write demolition contractors manage the risk with exclusions: collapse, explosion, adjacent property, asbestos, lead and pollution. Each one can remove an exposure the GC is relying on the demolition sub to carry. None of them appear on the ACORD 25. A demolition certificate showing $2,000,000 and $4,000,000 can sit on a policy that excludes the collapse of the structure being demolished and damage to the building next door.
Pikorua Security's demolition template reads the schedule of forms and the text of manuscript endorsements for collapse, explosion, adjacent structure, asbestos, lead and pollution language. Each finding is cited by form number and page in the deficiency notice, so the sub's broker knows exactly which endorsement must come off or which policy must be added.
Hazardous materials before the first pick
OSHA's demolition standard (29 CFR 1926 Subpart T) requires an engineering survey before demolition starts, and federal asbestos rules require an inspection for asbestos-containing material. Abatement is often a separate contractor, but residual asbestos, lead paint, PCB-containing materials and mold are routinely disturbed during demolition itself.
- Require contractors pollution liability with asbestos and lead coverage, not just a general CPL.
- Add transportation pollution coverage when the sub hauls debris.
- Collect the abatement contractor's CPL and license separately, and link the two vendors in Pikorua Security.
Adjacent buildings and the neighbor's claim
Urban demolition means party walls, shared foundations and occupied neighbors. Vibration, debris and undermining can damage adjacent buildings, and the neighbor will name the owner and GC. The demolition sub's CGL must cover damage to existing adjacent structures without a carve-out, and the GC needs ongoing and completed operations additional insured status to tender that claim.
Before mobilization, set the adjacent structure flag in the project rule template. Pikorua Security then requires the absence of adjacent property exclusions and checks that the umbrella follows form over the CGL without a demolition restriction.
How to verify a demolition sub's COI
A manual review of one COI and its endorsement packet takes 25 to 40 min (CFMA Time Study). These are the six checks, in the order Pikorua Security runs them.
- 1
Match the named insured to the subcontract
Compare the named insured on the ACORD 25 with the legal entity that signed the demolition subcontract, including the LLC or Inc. suffix. A trade name or DBA is not the contracting entity, and additional insured coverage follows the policy's named insured.
- 2
Check limits against your demolition exhibit
Confirm commercial general liability of $2,000,000 each occurrence / $4,000,000 general aggregate, an umbrella of $10,000,000 that follows form over CGL, auto and employer's liability, and statutory workers compensation. Then confirm contractors pollution liability and contractor's equipment are evidenced, because they do not appear on a standard ACORD 25.
- 3
Read the endorsement pages, not the checkboxes
A Y in the ADDL INSD or SUBR WVD column is not an endorsement. Confirm CG 20 10, CG 20 37, CG 20 01, CG 24 04, WC 00 03 13, CA 20 48, CG 25 03 and CG 20 38 are attached as forms, and that the ongoing and completed operations forms share the same edition date.
- 4
Scan the schedule of forms for demolition exclusions
Look for explosion, collapse and underground (XCU) exclusion, asbestos, lead and total pollution exclusions, adjacent property or damage to existing structures exclusion and CG 21 53 Designated ongoing operations. None of these appear on the certificate; they sit in the declarations schedule of forms and the endorsement pages.
- 5
Check carrier ratings and policy dates
Confirm each carrier is rated A- VII or better by AM Best and that no policy expires before the demolition scope and its completed operations period are finished. Set renewal reminders at 60, 30, 15 and 0 days.
- 6
Hold payment and site access until resolved
Keep the demolition sub's pay applications and jobsite badges on hold until every finding is resolved, then file the verified packet so it is ready if you ever need to tender a claim.
