Cannon Place is located above the Cannon Street rail station in the Central London Financial District. Having acquired the long leasehold interest in London’s Cannon Centre, Hines formed a joint venture with Network Rail to remodel the mainline and underground stations at Cannon Street.
The aim of the project was to create both Grade A office accommodation and retail space in a prime City of London location, utilising a striking architectural design, achieved through an eight-story office building.
The Cannon Place development required provision of a structural steel protection works package to protect the structural steel beams and columns that form the office building’s structure. In addition, thermal insulation was required for the soffits and ceilings between the office building and the station retail space located underneath. The new building was to achieve a BREEAM rating of ‘Very Good’. As well as high demanding environmental requirements, the station was to remain operational at all times during the construction works.
Using its vast knowledge of passive fire protection systems, Sharpfibre worked alongside the construction team and architect on the buildings fire protection design, specifying 10,000m² of Promat TD Board and Promat Promatect® -250 as the boarded fire protection solution for the structural steel. In addition, a further 4,000m² of Grace Monokote® Z-146 and Z-106 cementitious fire spray was specified for the elements of the structural steel framing that were exposed to external conditions. Finally, the thermal demands of the project were satisfied by the design and installation of 1,000m² of Rockwool Soffit Slab and Promat TLFR Soffit Board achieving a U-value of 0.20 W/m²K.
Sharpfibre were able to deliver the project on time, assisting in the creation of 398,110 square feet of Grade A office accommodation and 8,120 of retail space. The installation achieved the required BREEAM rating of ‘Very Good’ and the development of the Cannon Street station was recognised at 2013 National Rail Awards, where it won ‘Large Station of the Year’.
Works began in January 2010 and were completed in March 2011.
