The ECCO Ripley Development is the centrepiece of client Sekisui House’s Ripley masterplan community. Ripley is scheduled to accommodate 25% of Queensland’s population growth with a projected 133,000 new residents by 2036.

The projects completed by SEE Civil combine urban residential and retail development as well as major upgrades of existing road infrastructure and associated services.

The project was on a rolling program of earthworks for multiple stages followed by civil packages for those stages.  SEE Civil met the challenge of delivering lots on the ground for this high-growth development area.

Work also included scale trunk infrastructure works for utility providers as well as major and minor internal roads.

Project Scope

  • Bulk earthworks exceeding 1,400,000m3.
  • Construction of a 10,000m2 working platform for the Ripley Town Centre Coles shopping complex.
  • 9,000m stormwater drainage.
  • 7,000m water reticulation.
  • 9,200m sewer reticulation including large diameter trunk sewer up to 8m in depth.
  • Over 15,000m2 face area of concrete sleeper retaining walls across the packages.
  • ‘Versa’ block walls and class A sandstone boulder walls.
  • Soil nail anchors for embankment stabilisation along Ripley Road with shotcrete finishing.
  • 1km of external roadworks including four signalised intersections undertaken in a live traffic situation with complex switching and night works.
  • Bio retention basins
  • Construction of a regional detention basin bund including a 6m deep clay core, box culverts, and Q100 concrete spillway with pedestal structures for a future cycle path.
Key Construction Elements

  • A rollout of consecutive stages ensured that SEE Civil maintained sufficient resources to ensure ongoing delivery on multiple fronts of work.
Accolades

  • SEE Civil was the sole civil contractor for this Client on the ECCO Ripley development since 2014. This is a testament to the high quality of work performed, and excellent relationships developed between SEE Civil, the consulting engineer, and the Client, as well as meeting, and often exceeding, the budgetary and program needs of the client.
