Sierra Grand

The development consists of a 30 level residential complex, which includes a triple level hydrostatic basement, a post tensioned podium slab and a traditional reinforced concrete frame.

Burchills Engineering Solutions were responsible for structural and civil design services. Key aspects of design involved:

  • Wind tunnel testing with University of Sydney;
  • Post tensioned parking levels and tension piles throughout the basement;
  • High strength concrete used in lower levels for columns and walls to minimise column and wall size;
  • Creation of post tensioned podiums accommodating complex geometry requirements such as various ramps and steps to suit Gold Coast Highway and Surf Parade at different levels;
  • Implementation of an innovative jump form system encompassing a large proportion of vertical elements throughout the tower;
  • Design and documentation of typical floors to achieve a 4 day floor cycle;
  • Large void at Levels 1 and 2 when viewing from Gold Coast Highway;
  • Restaurants & cafes fronting Gold Coast Highway;
  • Heated indoor pool & spa;
  • Heated outdoor pool & spa; and
  • Sky Garden at Level 25.
