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

Interesting exam question :melting_face:

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.
