In this concise presentation, the founder of Sima (now part of the Think Project Group) – a veteran NEC Contracts tutor since 2007 and contributor to the drafting of NEC4 – outlines why robust record‑keeping is the linchpin of successful NEC4 projects. He argues that three inter‑related elements are essential: a healthy culture that avoids fact‑based arguments and preserves trust, deep site knowledge that fuels better decisions, and disciplined processes that prevent gaps and errors. Records are described as the "oxygen" of NEC4, enabling transparency, accountability, and data‑driven insights for future projects. With modern digital tools, maintaining simple yet powerful records becomes feasible, and the speaker cites Sima’s adoption by over 50,000 practitioners as evidence of its practical impact. Investing in strong records, he concludes, makes the rest of NEC4 processes far simpler and leads to healthier projects.
