Advanced Substructures were approached for an alternative design for this 7 floor group of apartments with 2 levels of basements in the luxury location of East Perth.

Top down construction removed the need for propping - reducing risk to neighbouring properties due to vibrational damage and excessive cantilevering of the retaining structure during construction.

Internal piles were sized for 6 levels and suspended slabs without capping were used to engage the temporary piles. Simultaneous construction of the superstructure was conducted until the 6th level was reached, at which point the pile caps were installed to support the final penthouse floor.

With side access to the building, dry sandy soils and a build team keen to learn about top-down construction, conditions were very favourable for Advanced Substructures' systems.
