Framework
An agreement that sets terms for work the buyer may order later, often from several suppliers. The value shown usually covers the whole agreement, not one job.
Open for bids / closing date
You must submit by the closing date and time, normally through the buyer's own online portal. Late bids are normally refused.
Clarification questions
A deadline for asking the buyer questions about the tender. It is earlier than the closing date.
Conditions of participation
What the buyer asks suppliers to show before they can be considered, such as experience, insurance or accreditations.
Bids are scored on
How the buyer will compare bids, usually a split between price and quality. A 60/40 split in favour of quality means the cheapest bid will not necessarily win.
Lots
A tender can be split into parts. You can often bid for only the lots that suit you.
Area (ITL)
The buyer names an official statistical area for where the work is, not a street address. Check the tender documents for the actual sites.

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.
