Five-Star Engineering for a Tough Urban Site
WSP acted as structural engineer on the hotel, which was built on a compact and highly constrained spot in a complex urban environment. Its design optimises the site’s potential, tackling significant constraints below ground caused by the adjacent buildings, streets and infrastructure.
Key structural engineering strategies contributing to this effort included the use of embedded walls, plunge columns and top down techniques to construct the deep basement, extensive 3D modelling of the both the sub- and super-structures and reduction of structural floor depths to maximise floor to ceiling heights. A compact and robust main core also allows the best net to gross area ratio.
The building’s green credentials were enhanced by use of post-tensioned slabs, cement replacement, geothermal piles and diaphragm walls, helping the Bulgari Hotel win the Concrete Society’s 2011 Sustainability Award.
