In this presentation, William Doyle MRICS, founder of Sima (now part of the Think Project Group) and NEC contract tutor since 2007, explains why NEC4 contracts are demanding yet essential for project success. He outlines three core elements—culture, knowledge, and discipline—that underpin effective NEC contracting. A healthy culture prevents unnecessary disputes, knowledge of on‑site conditions drives better decisions, and disciplined processes avoid gaps and errors. Doyle stresses that robust site records are the "oxygen" of NEC4, enabling transparency, accountability, and smoother contract administration. With modern data tools, these records can be captured simply, providing insights for current and future projects. Investing in strong records, he argues, makes the rest of NEC4 processes far simpler and leads to healthier project outcomes.
