station layout, and fire strategy had to be strictly followed. The station was to remain open for the entire project period and every activity was carefully planned to ensure that the station was safe from harm and passenger journeys were not delayed.

Cannon Place is a £214m 50,000m2 office space built above Cannon Street mainline and underground station in the City of London. Site work commenced on 3 September 2007 and was completed on 5 September 2011. Built on a 68m by 87m site, it is a striking and complex structure featuring two 21m deep cantilevered wings.

The site itself presented a number of design, planning and regulatory challenges. Sitting within the zone of protected views of St Paul’s Cathedral, the total height of the building was restricted to 51.3m. Coupled with Network Rail’s requirement that at least 5.1m space above the mainline running tracks must be maintained, this left just 32m within which an eight floor structure had to be housed to make the project commercially viable.

Meticulous and careful planning was required on this project to ensure that construction work was able to commence and continue with minimal disturbance to commuters and passengers using the rail services below. Around 60,000 people a day use the underground and mainline services running through Cannon Street. Before construction could even begin however there were several complex issues to overcome. One section of the brief, as part of the client’s partnership with Network Rail and London Underground, was to improve the station itself, including new accommodation for the underground, better disabled access and a new ticket hall. This meant that at each stage the Network Rail approval process for design, construction method, security, changes to

The site was also constrained by further factors: on the north side, it was not possible to lay any foundations because of the location of the shallow underground railway tunnels. The original Victorian viaduct remains over much of the site and the southern half of the site is a scheduled ancient monument, protecting the remains of a Roman Governor’s palace. Permission from English Heritage therefore had to be gained for any excavations and for determining the location of the foundations. Due to the design and construction restraints, integration of these two elements was the only practical way to proceed with the project. JCT’s Major Project Construction Contract

was chosen for this project as it is suitable for projects using a design and build process of procurement, which places overall design and construction responsibility with the main contractor.
