Summary of the contracting process

Diamond Light Source Limited is buying fabricated support components for arc vessels as part of its Diamond-II science facility upgrade at the Harwell Science and Innovation Campus in Oxfordshire. The work covers manufacture of vessel support fabrications, assemblies and machined components to the buyer’s designs, with assemblies delivered fully assembled and set to mid-travel where applicable. The supplier is responsible for contract management, purchasing materials, making the components and any required jigs and tooling, cleaning and protecting, quality assurance documentation, packing and delivery to Diamond Light Source. The buyer provides detailed manufacturing drawings and models covering geometry, materials, machining, stress relieving and coatings. Tenderers were also invited to recommend design changes to improve performance, cost or delivery.

The procurement is complete and the contract is active. Diamond Light Source used an open procedure for a single lot. NCF Engineering Ltd, trading as Ferrositi, was awarded the contract on 14 September 2026; it was signed on 23 September 2026. The contract runs from 23 September 2026 to 21 February 2028. Its awarded value is £603,705 excluding VAT (£724,446 including VAT). The original estimated lot value was £900,000 excluding VAT (£1,080,000 including VAT). Five bids reached the final stage, all from SMEs. Evaluation weighted price at 40%, technical quality at 22.5%, experience and capacity at 22.5%, delivery at 10% and commercial at 5%.

This award demonstrates demand from Diamond Light Source for precision-engineered vessel support fabrications, assemblies and machined parts for a major scientific facility upgrade. A credible competitor for a comparable requirement would need the engineering capability to manufacture accurately to detailed drawings and models, work with the specified materials and machining requirements, and carry out stress relieving and coatings where required. Suppliers would also need to manage materials procurement, tooling and jigs, component cleaning and protection, assembly, packing and delivery, backed by robust quality assurance documentation. The evaluation gave substantial weight to technical quality and to relevant experience and capacity, alongside delivery performance; price carried the largest single weighting. SMEs were able to compete successfully, as the selected supplier is an SME and all five final-stage bidders were SMEs. The buyer valued practical proposals to improve design performance, cost or delivery.

DLS allows researchers from academia and industry to investigate the structure and behaviour of the world around us at the atomic and molecular level. To continue delivering the world changing science that Diamond enables, the facility is being upgraded to Diamond-II, a co ordinated programme of development that combines a major machine upgrade with new instruments and complementary improvements to optics, detectors, sample environment and delivery capabilities, and computing, as well as integrated and correlative methods. This will be transformative in speed and spatial resolution and will offer users streamlined access to enhanced instruments for life and physical sciences. The scope of the contract is to manufacture various vessel support fabrications, assemblies and machined components to DLS designs as detailed in the specification. All assemblies should be delivered fully assembled and set to their mid travel where applicable. Completed components are to be delivered to Diamond Light Source. DLS will supply detailed manufacturing drawings and models with the specification. These specify geometry, materials, machining, stress relieving and any coatings required. Suppliers are invited to make recommendations to modify the designs to improve performance, cost or delivery in their tender submission. The contract for this includes: * Contract management * Purchase of all materials. * Manufacture of the components according to the table specified in specification * All jigs and tooling required for manufacture * Cleaning and protecting * Quality assurance documentation * Delivery * Packing
