Providence Estate, formerly owned by Oakland Properties and now a development for Stockland is a premier Queensland development in the busy Ripley Valley.

Providence is the largest masterplanned community in the Ripley Valley growth corridor where there is a massive $4.4 billion worth of residential projects currently underway, which will provide around 50,000 dwellings to house 120,000 people.

SEE Civil has completed various stages at Providence combining urban residential, retail development, and schools as well as major upgrades to existing road infrastructure and trunk infrastructure.

SEE Civil has delivered, and is still currently delivering, in excess of 1,950 residential lots since June 2015.

Project Scope

  • 4.2 million m3 of bulk earthworks across 29 stages, including 350,000m3 of hard rock blasting and processing. Extensive material management was required to achieve site classification requirements.
  • 46,000m2 of flexible pavement road network construction, including 1.5km of sub-arterial road construction.
  • 12.6km of stormwater drainage in a range of pipe sizes up to and including 2100mm diameter RCP’s. Construction of a 3300 x 2700mm triple cell RCBC including entry feature walls functioned as a main entry and statement into the estate.
  • 8.6 km of water reticulation including trunk mains and water booster station.
  • 11.3km of Nusewer PE sewer reticulation including trunk mains up to 8m in depth in hard excavation material.
  • High specification urban landscaping including paved finishes and bio tree planting units.
  • Full services installation including electrical and communications.
  • Extensive master planned environmental and sediment control measures including high efficiency sediment basins.
  • 15,700m2 of charcoal-coloured sleeper and segmental block retaining structure.
Key Construction Elements

  • A rollout of consecutive stages has ensured that SEE Civil has maintained sufficient resources to ensure ongoing delivery on multiple work fronts.
  • The ground conditions at Providence are varying with the most recent stages being predominately hard sandstone rock. During construction ripping, hammering, trenching, and blasting have been utilised to maintain program and deliver the work within the client’s stringent time frames.
