## Summary

The City of London is procuring structural engineering consultancy services for the Guildhall West Wing windows and cladding refurbishment. The requirement covers RIBA Stages 2 to 4, supporting the design development and technical delivery of refurbishment works to the building envelope. The buying organisation is The Mayor and Commonalty and Citizens of the City of London. The work is associated with Guildhall in the City of London, with delivery in the United Kingdom. This is a professional services requirement for structural engineering consultancies with experience of advising on window and cladding refurbishment projects and progressing designs through the relevant RIBA stages. The procurement is categorised as services, with the classification describing structural engineering consultancy services.

The procurement has been completed and the contract was awarded through a below-threshold limited competition. Alan Conisbee and Associates Limited was selected for the single lot. The award was made on 18 May 2026, and the contract was signed on that date. The contract runs from 25 May 2026 to 29 March 2027. Its value is £44,625 excluding VAT, or £53,550 including VAT. The appointed supplier will provide the RIBA Stages 2 to 4 structural engineering services for the Guildhall West Wing windows and cladding refurbishment. The tender reached complete status and the award is active. The available procurement information identifies the service scope and route, but does not state separate quality or price weightings.

This procurement demonstrates demand from the City of London for specialist structural engineering input within a major heritage or civic-building refurbishment context. Suppliers best placed for a future requirement of this kind would be structural engineering consultancies able to support RIBA Stages 2 to 4, translate surveys and design proposals into buildable technical solutions, and advise on the structural implications of replacing or refurbishing windows and cladding. Relevant experience in building-envelope projects, refurbishment in occupied or operational public buildings, coordination with architects and other consultants, and production of technical information for later construction stages would strengthen credibility. The appointed supplier is an SME, indicating that a focused specialist consultancy can compete for this type of professional services work.
