Misalingment of activity schedule and works information

[QS007]

There is a question and answer which might be relevant to this which I’ve linked below.

My answer is from an NEC3 standpoint, as you’ve not stated this i’m assuming it is. Your position is correct. If the works are described in the Works Information, then the risk for not including the missing scope within the Prices lies with the Contractor.

NEC ECC: Whose liability are items missing on thE activity schedule under option A?

Once a Contractor has realised that there is missing activity in the Accepted Programme and also on the Activity Schedule, what should the Contractor and Project Manager do? Does the Contractor should revise the programme and then the Activity Schedule? Should they be revised and submitted together or can they be revised and submitted at any time? Does the submission of one of them trigger the submission of the other one so that both can be accepted? Many thanks for your help
