The Task and Our Role
The multi award-winning City Extra Apartments building houses seven levels of residential units, two commercial tenancies opening onto Bolton Street, and two levels of basement carparking.  The 89 residential apartments offer a range of striking city, harbour and ocean views. Higher level apartments are set back from the streetscape to maximise natural lighting and ventilation throughout the building.

Lindsay Dynan provided the client with a low cost design option that minimised construction time using optimised precast building elements.  The steep topography of the site added to the complexity of the design, and necessitated significant underpinning and protection of adjacent buildings.

During construction and installation of CFA piles, unmapped mine workings were discovered under the site.  Construction was immediately suspended while investigation and rectification of the mine workings was undertaken.  The solution involved grouting of the mine workings with approximately 700m3 of specially designed “low flow” grout.
