NEC3 Option A - No breakdown of an activity in the Activity Schedule

[QS007]

Interesting exam question

There is a better answer already to this question which I’ve linked below, i’d suggest searching some more as this has been asked and answered considering subtle differences.

In short, the Contractor can change the Activity Schedule at anytime but it must be sent to the Project Manager for acceptance (54.2). The PM has 3 reasons for rejecting this (54.3)

This tends to happen at the beginning of a Contract as the Subcontractor doesn’t appreciate during tender the payment ‘terms’ are based on a 100% complete in line with the Programme, so you find yourself from time to time agreeing a revised Activity Schedule with the Contractor after contract award in order to allow them a good and steady cashflow throughout the Project.

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
