Preserving the past for the future
TTW’s expertise in both structural and heritage engineering was a critical consideration for the developers of an exciting new luxury hotel, which involves the adaptation of two existing heritage buildings in Sydney’s “Sandstone Precinct” on Bridge Street.
The Education Building will involve the addition of four levels above the existing seven storeys, and the excavation of three levels of the basement to provide 195 hotel rooms, bars, function rooms, and pool.
The heritage status and focus on the preservation of sandstone materials have necessitated close attention of the design team. Excavation of three levels of the basement within heavily fractured sandstone, while supporting the existing heritage Education Building above, requires careful coordination between temporary and permanent works. A feature of this building is a new 25m pool at level 5, which presents challenges to ensure that the existing structure is isolated from the pool to reduce vibration, the pool’s weight is supported, and to prevent any damage to the heritage fabric of the structure.
