In the unamended contract the cost of insurance is not part of Defined Cost so a contractor would usually recover this through the Fee.
It's difficult to comment on what an amended contract does / does not say without sight of the contract and without understanding what else has been amended that may impact on if this should be Disallowed Cost or not.
Most all risks policies cover more than just damage to the works and includes third party injury, death and damage to property. Therefore you need to be careful in wanting to disallow the entire cost of the policy as they have provided some of the cover required. Clause 83.1 is an indemnity clause that protects the Employer, and clause 85.4 provides further clarification. So even if the policy was inadequate in the event of a claim, the Contractor would have been liable to the Employer for loss of / wear / damage to the works before take over (see clause 80.1). Also, presumably if the works had been insured correctly the premium paid by the Employer would have been higher from the start?
On checking the definition of Disallowed Cost at clause 11.2(25) it's hard to find a reason to disallow the cost, however you need to check your Z clauses over with a fine tooth comb to be certain.
