Atrium Steelwork & Acoustic Cladding to Support New Smoke Extraction System
Structural Steel Roof Alterations - LSE Marshall Building
Design, manufacture and installation of new atrium glazing support steel work to the 9th floor including additional posts.
The overall purpose of the roof alterations at The Marshall Building at the London School of Economics was to enhance fire safety as part of a comprehensive improvement project. Specifically, the works on the Level 9 outdoor terrace and atrium rooflight focused on installing a smoke extractor system to improve fire protection while preserving the building’s architectural design. We installed a lifting beam for steelwork, followed by rooflight steelwork installation and a crane operation removed atrium glazing, which was reinstalled once the new raised steelwork was put in place.
Key activities included constructing a temporary roof structure, removing planters, and installing steelwork and a plenum at the atrium’s top to support the smoke extraction system. This plenum enhances fire safety by ensuring efficient smoke removal, maintaining clear evacuation routes, and complying with fire protection regulations while preserving the building’s architectural design. We acoustic aluminium cladding and baffles to reduce noise created in the atrium, especially from people using the stairs.
