The site is a live operational medical-research facility. Maintaining safe operations, continuity of steam, electrical resilience and controlled access is fundamental to the delivery approach. The objectives are; • deliver a safe, coordinated and maintainable replacement steam-boiler installation without unacceptable disruption to the live site; • secure a technically credible design and executable programme covering design, enabling works, installation, testing, commissioning and handover; • obtain a transparent and comparable activity-schedule price under NEC3 ECC Main Option A; • allocate interface, access, electrical-capacity, continuity and commissioning risks clearly; • secure measurable social-value commitments relevant to the contract and local delivery; and • appoint a contractor capable of collaborative NEC delivery, disciplined change control and complete handover.
