The appointed supplier(s) will provide structured assurance through stage-gated reviews, ensuring traceability from requirements through to design outputs, and confirming that designs are safe, compliant, and aligned with best practice. This includes assessment of constructability, operability, maintainability, and interface management across the project. Deliverables include assurance reports, validation statements, and the identification and tracking of corrective actions, providing confidence that the design is fit for purpose and ready to progress to detailed design and construction. The framework enables NGN to award call-off contracts for independent design assurance services, supporting the safe, compliant, and effective delivery of the ECH programme.
