FP McCann was contracted to manufacture and deliver precast concrete units for the construction of the New White Hart Lane Stadium.

The project scope entailed the construction of a completely new structure on a brownfield site directly adjacent to their existing stadium, consisting of an entirely precast concrete main stadium bowl with a steel and glass canopy structure mounted above the seating area.

The concrete mix used was designed to minimize the finishing work required to the units and to ensure a consistent unit quality. The mix has sustainability credentials to reduce its carbon footprint.

In total, approximately 15,000m3 of concrete were used in the project, equating to 2,500 lorry loads. We also employ renewable energy sources to power our production facilities as a means of offsetting the carbon produced in the manufacturing process.

The result of this mix design was to create a material with the correct flow, working time and robustness that allowed for next day demoulding and minimal finishing work, resulting in a blow hole free finish to the external faces of the units. The mix also met the aesthetic requirements for the new stadium, as it produced a lighter coloured concrete rather than the traditional grey mix.

The terracing units were designed to be both robust and relatively light, aiding both manufacturing and installation. This was achieved by increasing the unit steel content to allow the depth to be reduced, thus reducing the concrete volume. Terracing units were installed onto large precast raker beams, which presented challenges in terms of steel fixing, mould work, production and transport.

The design had to be robust enough to support rows of terracing units, but light enough to be transported to London by road and installed using tower cranes.
This was again achieved with a slight increase in reinforcement density resulting in reduced depth and overall volume.
