Robert Bird Group was commissioned by the developer of this prestigious residential tower in the Sydney CBD to provide structural value-engineering, construction methodology, demolition and re-construction works sequencing, and temporary works engineering services for the project. The unique engineering challenges that RBG solved included the temporary retention of an existing 26-level-tall structural steel frame (formerly an office tower), whilst the existing façade and floors were demolished.
RBG worked with the demolition and re-construction contractors to develop a detailed demolition and reconstruction sequence which adequately addressed the site access, limitations of the capacity of the existing 50-year-old structure, and coordination of temporary works with permanent works.
RBG also provided shoring and retention design for the existing basement, and underpinning and stabilizing works design for the existing tower whilst new foundations up to 5 metres deep were constructed to support the 67-level permanent works. Basement retention included an interface with the future Sydney Metro rail corridor on Pitt Street.
