NEC4: Managing the ECC Lifecycle is a definitive guide to the NEC4 Engineering and Construction Contract. It delivers practical solutions for professionals responsible for day-to-day contract administration. The book follows the lifecycle of a live project by walking the reader step-by-step from initial procurement through to completion. The book translates complex contract mechanics into clear guidance and covers fundamental topics such as early warnings, compensation events and programme management. It provides an in-depth analysis of target contracts and the dispute resolution process that shapes current case law. These sections use real-world examples to demonstrate how the contract operates in practice. A closing chapter provides a structured comparison with FIDIC for professionals transitioning between international standards.
NEC4: Managing the ECC Lifecycle bridges the gap between contract theory and commercial implementation, and is an indispensable guide for anyone administering an NEC contract or learning how to use it.
