Waterlea Estate

Civil Design

Location: Walloon, Ipswich, QLD

Client: RBG Holdings

Specs: 1,500 lot subdivision


Premise was commissioned by RBG Holdings to undertake the civil design and construction management of a 1,500 lot subdivision, located within the Walloon township.

The development was subject to a multitude of constraints, such as:

  • 70% of the site located within the Q100 flood level
  • A mapped waterway corridor running through the site
  • Limited access to water reticulation infrastructure
  • No access to sewerage reticulation infrastructure
  • State Controlled Road located through the site
  • Unfavourable geotechnical conditions

Premise is proud to have successfully delivered key outcomes, including:

  • Design and management associated with TMR controlled roads
  • Design of trunk sewerage infrastructure – gravity mains and a temporary sewerage treatment plant
  • Hydraulic modelling and design – lowering an existing waterway to form a channel through the site
  • Hydraulic modelling and detailed design of the 15ha regional detention basin
  • Installation of a major culvert crossing beneath the existing roadway
