Calfordseaden was appointed by Vivid to provide EA, Clerk of Works and Principle Designer services.

The site comprises the former HM Kingston Prison in Portsmouth which was opened in 1877 and closed its doors to its inmates in 2013. The site was then purchased by a heritage developer, who obtained planning permission for the refurbishment and conversion of the original prison building into residential accommodation and the construction of 5no further new build 4 & 5 story apartment blocks within the confines of the main prison walls.

Our initial involvement was to assist our Client in negotiating the acquisition of the land from the Heritage Developer on which the 5 new build blocks were to be constructed. These negotiations were relatively complex due in part to the agreement for specified ‘infrastructure enabling works’, which would need to be completed before Vivid Homes appointed Contractor could commence.
Simultaneously with the land deal, calfordseaden prepared tender documentation including detailed Employers Requirements in order to competitively tender the new build scheme to a selection of suitable developers. Following receipt of competitive tenders, post tender interviews, negotiations and a value engineering process was undertaken to ensure that not only did the Client obtain the best value for money from a developer with proven relevant experience; an element of key importance was a competitive and achievable build programme. Both Land and Build deals were completed successfully in order to exchange simultaneously.

calfordseaden was also appointed to provide Rights of Light advice and Party Wall services for a number of existing residential dwellings in close proximity to one of the new build apartment blocks. These elements are in the process of being regularised in order to safeguard the interests of both our Client and the neighbouring residents.

An additional challenge was the close proximity of the site to Network Rail infrastructure, which due to the potential risk of crane oversail, required the preparation and entering into of a Basic Asset Protection Agreement (BAPA). calfordseaden foresaw the requirement for this agreement during the tender documentation stage and ensured that the Employers Requirements specified all responsibilities in this regard to fall on the developer and itemised all necessary costs as a contractor fixed sum item in the Contract Sum Analysis.

At the time of writing, the enabling works package is nearing completion, with the appointed Developer due to commence works imminently, on what both our Client, Vivid Homes and Portsmouth City Council, consider a flagship scheme.
