Subcontractor trades
Subcontractor insurance requirements, trade by trade.
A roofer, an excavator and a landscaper should not be held to the same exhibit. Pikorua Security applies 14 trade rule templates that check the limits, endorsements and exclusions each trade actually carries, and flags the gaps a certificate never shows.

Trade risk matrix
What each trade's exhibit should require
Check marks mean the coverage is typically required for that trade. Notes mark conditional requirements, such as professional liability only when the sub performs design.

Exhibit design
Why high-hazard trades need stricter exhibits
A flat $1,000,000 / $2,000,000 exhibit is a pricing decision you did not make.
One exhibit for every trade means the roofer, the demolition contractor and the landscaper are measured against the same limits. The roofer and the demolition sub carry the severe exposures (falls, fire, collapse, adjacent property), so the flat exhibit leaves your umbrella and retention absorbing what theirs should. The landscaper is asked for coverages it will never use and spends weeks chasing them.
When a carrier denies an additional insured tender, the GC's average out-of-pocket litigation and retention loss runs $150,000 to $450,000 (Commercial Casualty Actuarial Study). Trade tiers put the larger limits and the strictest endorsement rules where that loss is most likely to start.
Exclusions scale with hazard
- Hot work, height limits: roofing
- XCU, subsidence: excavation, demolition
- Professional services: glazing, steel, fire protection
- Total pollution, fungi: HVAC, plumbing, painting

Completed operations tail
Structural, envelope and MEP trades produce most of their claims after turnover: leaks, settlement, connection failures, equipment faults. For those trades the exhibit should name a completed operations period and require CG 20 37 on every renewal, not just the first certificate.
Specialty coverage is separate evidence
Pollution, professional and inland marine policies rarely appear on an ACORD 25. Pikorua Security asks the broker for each one by name through the zero-login upload link, reads the declarations, and checks the GC is an additional insured where the policy allows it.
