The facility comprises a circular building that houses the Synchrotron machine together with the associated beamlines, labs and support facilities. Other long-beamline buildings and a specialist Cryo Electron Microscope centre are located adjacent along with a supporting office facility. The Diamond-II Project is a £519.4m project to replace the machine with a 4th generation source and includes capital investment in three flagship beamlines to further exploit opportunities offered by the new machine, and investment in modern computing infrastructure and methods, including AI, to boost scientific productivity. Full funding for this project from the UK Government and the Wellcome Trust was confirmed in September 2023. https://www.diamond.ac.uk/Diamond-II.html We are still exploring whether the works will be considered as 'construction of a structure' under CDM Regulations and would like to speak to experienced organisations who can share their thoughts, ideas and experiences of other projects to help shape how Diamond moves forward with this particular part of Diamond-II. Why are we investigating two options for the role of managing Machine upgrade activities within Zone 13 of the Synchrotron As such, the works may either be carried out utilising the services of a Principal Contractor (PC) together with a Support Team if deemed that the works constitute 'construction of a structure' under CDM or carried out utilising the services of an Installation Manager (IM) together with a Support Team if the works are not deemed to be 'construction of a structure' under CDM. This appointment will cover the period leading up to the start of the main shutdown (approximately 6 months) and then for Machine upgrading works within the main shutdown (12 months). Period leading up to the 'main shutdown': it will be necessary for the PC or IM, together with an element of the Support Team, to commence involvement at some period prior to the start of the 'main shutdown' (i.e. a period of approximately 6 months) to familiarise themselves with the site, the scope of works, Diamond procedures and form relationships with key Diamond stakeholders. Machine upgrade works in main shutdown: the physical installation of the Machine works is scheduled to start Dec'27 and be complete in Dec'28. Further commissioning works will be on-going from this date, but this will be managed separately by Diamond. The Machine upgrade works will include: • Strip-out of the original Diamond "Machine" components, installation of new components, connection and initial checking, carried out by Diamond staff • Pipework upgrade contract, supervised by Diamond staff • Cabling upgrade contr... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/dlspme0001-principal-contractor-or-installation-manager-with-support-team-ocds-h6vhtk-051085) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** planning - **CPV codes:** 71310000 - **Delivery regions:** UKJ - **Delivery countries in notice:** GB - **Contract Period:** 04/07/2027 to 11/12/2028 ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F020335-2025) - **Last Source Update:** 2025-05-12T09:33:08.000Z - **This document generated:** 2026-10-28T14:57:18.283Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-051085
