Expedition are the structural and civil engineers for Pritzker prize-winning architect Fumihiko Maki‘s first UK building for the Aga Khan Development Network at Argent’s King’s Cross redevelopment.
The structural design was closely coordinated to realise the architectural vision. Uninterrupted internal volumes were created and custom-fabricated perimeter columns were installed to the tightest tolerance, to minimise the external wall thickness.
The massing and arrangement of the teaching and library floors necessitated long-span solutions and a 3m cantilever of the entire southern edge of the building to form a dramatic overhang. Specified areas of the library are designed to support high intensity book storage and a rare books archive.
The floors are supported by steel beams fabricated from plates of varying thickness optimised for span and load, and designed for building services to pass through for maximum overall efficiency. These long-span floors adhere to tight deflection limits to achieve the smallest façade joints as well high levels of user comfort.
The nine-storey steel structure with reinforced concrete cores extends above the double-height concrete basement is reinforced concrete cores. Exposed steel supporting the scenic lifts and atrium roof are precision elements with concealed connections to deliver users to the highest roof levels supporting exquisite gardens with deep planters and calming water features.
