Project: Trying limitations and logistical challenges were met with defiant innovation as One Hennessy began to be constructed. The inverted pyramid structure at the core of the 32-storey new build created an opportunity for laudable health, safety and wellbeing management, ensuring that site workers were able to manoeuvre safely with a passenger hoist fixed to a temporary steel platform with a mast able to transfer lateral loads.
The inverted pyramid structure was made possibly by specifically designed timber formwork, 3 metre deep tension beams and belt truss. Inclined columns and timber formwork supported by thousands of inclined tie rods reduced deflection and ensured accuracy. With advanced prefabricated works offsite, modularisation reduced site activities and created better environmental control.
Rooftop vegetation mitigates the urban heat island effect and maximising natural light and minimising energy loss helped One Hennessy achieve LEEDs Platinum Rating for Green Buildings. In the construction of One Hennessy, more than 80% of building materials were regionally sourced, and 90% of construction and demolition waste was diverted from landfill.
CABE member and project manager for One Hennessy, CY Wong, was responsible for the overall construction process, monitoring and co-ordinating with an effective open-communication policy that encouraged knowledge sharing and flexibility. This led to ease of implementation, cost-efficiency, and a good work culture on site.
