NEC ECC: Contractor to provide Insurance

I could not ascertain whether the ECC required the Contractor to provide insurance for loss of or damage to the Employer’s structures?.

Any response would help as I need to see if this is added into the Z clauses

This is covered under clause 84.1 of the NEC3 ECC in the Insurance Table which requires the Contractor to provide insurance against liability for loss of or damage to property unless the Employer has stated in Contract Data that it is to be provided by them.
