What this issue means
Stated limits on the certificate are lower than your written subcontract insurance requirements.
Why it matters for mobilization
Under-limits coverage does not satisfy your risk transfer program or owner requirements.
How to resolve it
Use your requirements spec and ask the broker to reissue with compliant limits or provide evidence of increased limits.
When approval should be blocked
Do not approve until limits meet contract minimums on all required lines.
Recommended next step
Request a revised certificate meeting your contract limit minimums.
