## Summary

The Ministry of Defence is spearheading a significant procurement process titled "Supply Chain Notice: Portsmouth Naval Base Building Investment Programme (Design & Build)", which falls under the industry category of office block construction work. The project aims to sustain and regenerate five critical buildings at the Portsmouth Naval Base, with a focus on both listed and operational structures. Located in the South East region of the United Kingdom, this extensive endeavour is currently in the planning stage, with an initial engagement period closing on 23 May 2025. The procurement process will include several phases up to the design and build contracting, anticipated to be completed by December 2025 for the initial phase.

This tender provides a notable opportunity for larger construction firms experienced in complex office and warehouse store projects, given the significant estimated budget of £40-60 million and the project's duration of approximately six years. The work involves phased approvals and contracting, beginning with detailed designs under RIBA stages. While SMEs and VCSEs may find this project challenging due to size and complexity, larger organisations with a specialty in heritage and listed building renovation will find excellent growth potential. Businesses with a strategic focus on engaging with military and government infrastructure developments are particularly well-suited to pursue this opportunity.
