At AEnvCoW’s 2025 Spring Conference in Manchester, Richard Patterson – Chartered Civil Engineer and NEC specialist with over 35 years’ experience – presented and led highly sought-after workshops on Using NEC X29 as a Vehicle to Guide Environmental Compliance and The Role of the EnvCoW as a Contractual Extension of the NEC Site Supervisor. These sessions were exceptionally well received. Building on the discussions and questions raised, Richard has written this article examining where and how the EnvCoW fits within the NEC Engineering and Construction Contract. We are pleased to now share it with a wider audience.
