Opal Hillside Aged Care Facility
Mt Hutton, NSW


OPAL Aged Care

Construction Budget


Project Details

The development comprised:

  • Construction of 128 bed residential aged care facility with an overall building footprint of over 6800m²
  • Structure included 3 wings each of 3 to 4 storeys with one wing including and underground basement for services and amenities
  • External carparking and access roads for servicing vehicles

Challenge Faced / Engineering Problem Solved:

  • Variable founding conditions and large mine subsidence ground strains required sliding bearing pads and compressible material around footings
  • Variable earthquake design requirements due to varying building levels, sliding bearing joints and requirements to support base shear forces
  • Sloping site required detailed temporary shoring considerations and retaining wall design
  • Detailed site internal roadworks modelling to facilitate suitable stormwater drainage and satisfying accessibility requirements on a steep site
