## Description
MHRA invites tenders for the detailed design, supply, installation, testing, commissioning and handover of replacement steam-boiler systems at MHRA Laboratories, Blanche Lane, South Mimms, Potters Bar, Hertfordshire EN6 3QG. The contract will be awarded to the supplier submitting the most advantageous tender in accordance with the published award criteria and assessment methodology in this ITT.
The works form South Mimms Electric Steam Boiler Project and are intended to replace three existing individual 3,900 kg/h gas-fired steam boilers with two individual 3,000 kg/h electric steam boilers, together with the associated mechanical, electrical, controls, building, civil and enabling works. 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.
