Summary of the contracting process

The National Maritime Museum is procuring specialist museum-exhibition services for the Royal Observatory Greenwich’s First Light Project. The appointed Orrery Contractor will develop, engineer, fabricate, install and commission two mechanical models of the solar system: one kinetic and one interactive. The orreries will be installed at various points across the Royal Observatory Greenwich site. The scope includes elements of contractor design, together with coordination with exhibition designers and other contractors working both on and off site. This suits businesses delivering complex interpretive, scientific or cultural installations, particularly those able to combine mechanical engineering, interactive exhibit development, fabrication and site installation within a live exhibition project environment. The procurement covers the United Kingdom, with the work centred on London and the Royal Observatory Greenwich.

The procurement has reached tender: the buyer invited offers following a two-stage competitive flexible procedure. Contractors first go through a preliminary supplier questionnaire process, after which shortlisted contractors are invited to tender and site visits are arranged. Expressions of interest are due by 21 August 2026 at 12:00, and enquiries close on 14 August 2026 at 17:00. The single lot has an estimated value of £155,000 excluding VAT, or £186,000 including VAT. The contract period is 15 March 2027 to 17 July 2028, with the award decision due by 1 March 2027 at 23:59. Evaluation is weighted 60% technical quality and 40% commercial considerations. Electronic submissions in English are allowed through the eSourcing portal.

This opportunity is suited to an SME or larger specialist contractor with demonstrable capability across the full lifecycle of bespoke mechanical exhibits. Relevant strengths include concept development, contractor design, mechanical and interactive engineering, prototyping, fabrication, installation and commissioning. Suppliers will need to coordinate effectively with exhibition designers and other contractors, manage interfaces between off-site manufacture and on-site delivery, and produce reliable visitor-facing equipment for a museum setting. Experience delivering kinetic or interactive scientific, educational, cultural or heritage installations would be particularly relevant, as would the ability to develop accurate mechanical models of the solar system. The requirement favours a supplier able to manage two separate orreries as one coordinated project and provide the technical capacity needed through installation and commissioning.
