‘Blue at Lavender Bay’ saw the redevelopment of an existing commercial building into 129 premium 1-, 2- and 3-bedroom apartments over 21 floors, overlooking Sydney Harbour. This involved major works such as the relocation of the lift and stair cores, changes to facades with balcony and wintergarden installations and the addition of two floors plus reinstatement of rooftop plant. WGE provided engineering consultancy to facilitate the transformation of the building and upgrade of services to suit luxury residential occupation including:

  • Design of new electrical systems and technologies suitable for premium market
  • Design of new centralised mechanical systems, carpark exhaust systems and stair pressurisation systems
  • Design of new cold water, gas and centralised hot water systems
  • Design of new sprinkler protection, smoke detection, and window drenching systems
  • Design of the external public domain and upgrade of the stormwater drainage connections to public infrastructure to meet industry standards.

3D point cloud technology captured the existing structure, creating accurate, detailed BIM modelling to facilitate services co-ordination and design – particularly in the basement – which assisted in the staging of works in real time. Computational Fluid Dynamics (CFD) modelling helped identify a jet fan solution within the car park that reduced ductwork requirements and associated costs while increasing parking provision.

Spatial constraints were experienced in various areas which were remedied through collaboration with the architect to manage services allowances and optimise apartment layout efficiency; working with suppliers to install within a reduced footprint and combining/centralising systems where possible, while advising on code compliance. Innovative technology was introduced with minimal impact on the building infrastructure – such as EV car charging with centralised smart controllers – to provide for increase in future demand for this facility.
