NEC4: Understanding the Activity Schedule

31 Mar 2026 · 62 min

The webinar explains the NEC4 activity schedule, its purpose, and how it operates under Options A (priced contract) and C (target contract). It clarifies that the schedule is a pricing tool prepared by the contractor, not a scope document, and outlines its role in interim payments, cash‑flow management, and compensation events. The presenters discuss the contractual obligations to correct or revise the schedule under Option A, the removal of the revision requirement under Option C, and the mechanics of changing prices when compensation events occur. Two practical methods for updating the schedule after compensation events are demonstrated, along with guidance on granularity, risk of errors, and the impact on contractor cash flow. The session also offers advice for clients on why they should not prepare the schedule themselves, stresses the importance of aligning the schedule with the programme, and highlights common disputes arising from administration and interpretation. The webinar concludes with recommendations for collaborative contract administration and a preview of the next session on disallowed costs.
