Preliminary Market Engagement - Commercial & Industrial Development Works, SE Hampshire - Multi-Contractor Framework Agreement

INTRODUCTION Portsmouth City Council ("the Council", "the Developer", the "Authority") is undertaking a Preliminary Market Engagement (PME) exercise to inform the future procurement strategy that will be used to establish a multi-contractor framework agreement for the delivery of commercial & industrial development works. The framework agreement will be used to deliver development works within Portsmouth and neighbouring South East Hampshire areas, focusing upon further development of the Council owned Dunsbury Park located within Havant and Lakeside North Harbour located within Cosham. Following completion of this PME exercise, the Council will undertake a formal Procurement Act 23 (PA 23) compliant competitive procurement process to establish the future framework agreement. The Council is targeting to have commenced the formal procurement process on 20th July 2026, to allow for award by early December 2026 and commencement of the framework agreement from 4th January 2026. The framework agreement will then run for a 4-year term extendable by a further 2 years in increments to be agreed. Spend via the framework agreement over the total term could be up to £150M, although this is not guaranteed and will be dependent upon future tenant demand for new commercial / industrial facilities at the Council sites. Development works may be brought forward on both a secured tenant build to suit and prospective demand basis. Development of plots will be undertaken incrementally in phases in line with dynamic demand requirements with works let via individual call off contracts. The value of individual call off contracts will be variable but is expected to range between £5M - £20M on average, based upon current construction costs. Call off contracts will be predominantly let on a 2-stage contracting strategy utilising the JCT Pre-Construction Agreement for 1st stage pre-construction activities and the JCT Design & Build Contract used for 2nd stage construction works. DEVELOPMENT SITES DUNSBURY PARK The Council is the freehold owner of some 21 hectares (52 acres) of land adjoining J3 of A3M junction at Waterlooville. The site is marketed under the title of 'Dunsbury Park' and is located at Fitzwygram Way, Hampshire, PO9 4EE. The Council has to date delivered road infrastructure and cycle path, site levelling, utility connections and approx. 42,000 sqm of commercial buildings. The future development on the site comprises 5 no. units with a combined area of approximately 42,000 sqm of B2/B8 use. The current occupational position, planning strategy and remaining land for development as of May 2026 is included within the PME Brief accessible via the Council's e-sourcing system In-tend. The Council estimates that value of work that could be let via the framework agreement to develop the remaining plots at Dunsbury Park could equate to approx. £70M over the term of the agreement. However, as noted above no guarantee in respect of volume and value of call off contracts let via the framework agreement can be provided as this will be dependent upon future tenant demand and financial viability considerations.
