NEC ECC: Can Contractor be paid for an item they have not been included on the activity schedule?

Under an ECC Option A, the Contractor submitted the first programme for acceptance in accordance with the contract timescales but now realises a 30m length of security fencing has not been priced, isn’t shown on the Activity Schedule, nor is it shown on the programme. The fencing is clearly identified in the Works Information.

Can the Contractor be paid for this fencing?
