On the project

One Option C job, from February 2026 to the final account

Every lesson follows the invented Aldermere Flood Relief Scheme. Short side cases cover the other main Options.

£592,185

An application arrives a day late, and the cap holds this back for four weeks.

£21,000

An audit of four weeks of costs, worth £702,400, takes this out of Defined Cost.

£38,000

A storm repair comes off Defined Cost in full, because the Contractor had to insure the event.

£136,000

The Contractor's final share, once the final account is agreed.

Who it is for

People who work on NEC4 accounts

For people on either side of an ECC contract who work on the account, from the first assessment to the audit. It also suits cost consultants and auditors. It starts from first principles and ends with the borderline questions practitioners argue about.

Clause references are to the NEC4 Engineering and Construction Contract, June 2017 with amendments January 2023. Independent material. It is not published or endorsed by NEC. The project and the people are invented.
