Separate price changes from schedule revisions
Under Option A, the activity schedule supports the payment assessment for completed activities or groups. A compensation event can change the Prices through the compensation event process. Revising the breakdown or descriptions is a different question from establishing an entitlement to more money.
Clause 55 governs revisions to the Activity Schedule under NEC4 ECC Option A. Revising the schedule does not by itself create entitlement to increase the total of the Prices. Check the activity schedule provisions alongside the event or other contractual basis for the proposed change.
For a practical explanation of the schedule’s role, see GMH’s webinar on understanding the Activity Schedule.
State what is changing and why
Identify the affected activities, the relationship to the programme and the reason for revision. Explain whether the proposal changes timing or allocation only, or reflects an implemented change to the Prices.
Submit the revision through the contract’s acceptance process. Check the applicable grounds for non-acceptance, including the relationship to the programme, allocation of Prices and changes to their total. Acceptance of a revised programme does not itself accept a revised activity schedule.
Keep a visible reconciliation
Retain the previous accepted schedule and show each changed description, value and activity reference. Reconcile the total to implemented compensation events and other authorised adjustments. Avoid double counting the same change in both an event and a redistributed activity.
Review the cash-flow effect of the activity breakdown. Splitting an activity in a working spreadsheet does not automatically create a right to payment for incomplete work.
Use one review pack
Bring together the proposed schedule, relevant programme, reason for revision, price reconciliation and contractual communications. Record acceptance or reasons for non-acceptance and update the payment records consistently.
