100 Liverpool Street, London

https://www.siderise.com/projects/100-liverpool-street-london Designed by Hopkins Architects for developer British Land, 100 Liverpool Street is a 520,000 sq ft mixed-use building and the newest major project in the ever-popular 32-acre Broadgate area of the city. Partly built above Liverpool Street station and adjacent to the new Crossrail station, the project - which saw an outdated building demolished and then rebuilt using the existing structural steel frame - is a major feat of engineering, due to both the design and the constrained site. With the new curved façade presenting a number of compartmentation challenges, façade contractor Focchi worked with SIDERISE who provided the certified CW-FS Fire Stop system for the unitised curtain walling. Due to the curved nature of the façade and inner structure, the firestop system at the perimeter slab edge was required to follow the curve and maintain a consistent minimum 10% compression fit, to accommodate the design life movements of the façade structure. This is where the SIDERISE CW-FS came into its own due to the unique Lamella orientation of the stone wool fibres which make up the company’s curtain wall range of perimeter fire barriers. The CW-FS system was able to follow the curves without compromising the movement capability of the firestop system, or the simplicity of installation. Façade contractor Focchi installed the SIDERISE CW-FS120 perimeter barrier and fire stop system to seal the void between the floor slab and the external facade and provide vertical compartmentation at every floor level. The product offers a unique combination of effective on-site performance and easy installation, supported by SIDERISE’s extensive technical support.
