NEC4 Disallowed Cost Explained

In Episode 9 of the NEC4 Webinar Series with CECA, Ben Walker and Glenn Hide explore disallowed cost under main options C, D and E (with a brief look at option F). They walk through why disallowed cost exists as a commercial control mechanism in cost-reimbursable contracts, where it sits in the payment assessment process, and unpack each of the six categories defined in clause 11.2(26). David Allen from CECA Southern adds the contractor's perspective on how good records, early warnings, and collaboration with the project manager are the most reliable ways to avoid disallowed cost in practice.

NEC4 Understanding the Activity Schedule

This episode covers the NEC4 activity schedule under Options A and C, explaining what it is, how it drives payments, and why the contractor should prepare it rather than the client. Ben Walker and Glenn Hide walk through the mechanics of correcting, revising, and changing the activity schedule, including two practical approaches for updating prices after compensation events. David Allen from CECA Southern adds a contractor's perspective on the financial and practical pitfalls of poorly structured activity schedules.

The Role of Contract Data

This episode covers the role of contract data in NEC4, explaining how data part one (client) and data part two (contractor) work together to fuel the contract. Ben Walker uses the analogy of the contract as a car and contract data as its fuel, before exploring italicised terms as the bridge between conditions and data. The session features a live demonstration of NEC Digital by Iain Jeffries from Thomas Telford, showing how the platform prevents incompatible option selections and streamlines the contract data completion process for both clients and contractors.
