What this issue means
The certificate does not list a Commercial General Liability policy.
Why it matters for mobilization
GL covers third-party bodily injury and property damage arising from the subcontractor work.
How to resolve it
Send your insurance requirements to the sub broker and request an ACORD 25 with GL limits and policy numbers.
When approval should be blocked
Block site access when your contract or program requires GL and it is not documented on a current certificate.
Recommended next step
Request a certificate including Commercial General Liability with limits meeting your contract.
