Under NEC, site records aren't optional. They're contractual.

In this panel discussion, William Doyle MRICS and two other experts examine why site records are a contractual necessity under NEC contracts. They begin by affirming the universal importance of records for health, safety, quality, and commercial assurance, then explore how NEC specifically addresses record‑keeping. The speakers note that NEC does not single out "site records" but references particular records (e.g., weather measurements, defined‑cost data, test‑inspection logs) in core clauses and the 40‑series clauses. They explain that the contract sets out what must be recorded, while the NEC guidance notes and the project scope explain why and how to achieve it. The discussion stresses the need to read and, where appropriate, augment the scope to embed detailed record‑keeping requirements, citing the many touch‑points between scope and conditions (around 30+ in NEC3). They argue that over‑prescribing the method of record‑keeping could stifle innovation, so the contract intentionally leaves the how to the parties, supported by collaborative tools and systems. Practical advice is offered on programme submission intervals, the "bow‑wave" concept of increasing granularity as a project progresses, and the importance of heightened vigilance around early warnings and compensation events. The panel concludes that while the NEC contract correctly balances prescriptiveness and flexibility, practitioners should use the scope and ongoing collaboration to define the level of detail and timing for records, and only amend the scope via a project manager when consensus cannot be reached.
