20 Fenchurch Street the 37 storey skyscraper, also known as the “Walkie Talkie” due to its distinctive shape, is one the latest editions to the London skyline. The building, which stands at 160 metres tall is designed by architect Rafael Viñoly and includes a viewing deck and sky gardens on the top 3 floors, which will be open to the general public.
The requirement for structural steel protection to 90 and 120 minutes and an extremely demanding build programme meant that the Cementitious Fire Spray passive fire protection adopted took into account logistics, speed of application and stringent environmental controls. With a total of 80,000m2 of structural steelwork to be protected at the rate of one floor per week, Cementitious Fire Spray was fast to apply and quick to cure, whilst being able to withstand exposure to the elements once applied. Strict environmental controls and regular air monitoring imposed by the Corporation of London, as well as a completely exposed building envelope and high wind speeds where all accommodated by our unique Encapsulation system.
With a bespoke purpose build pumping station located on the ground floor meant that the mixed materials could be supplied direct to the entire building from one location. Using one of the building services risers, aluminium riser pipes were installed; allowing the materials to be pumped centrally without the need of the already heavily utilised tower cranes or hoists.
Fire protection works began on site in June 2012 and despite especially cold weather and snow during the winter months, the Cementitious Fire Spray application was completed on time in March 2013. In addition to this, in excess of 10,000 openings including service penetrations and ducts had been fire stopped.
