A paving plan which allowed for large trucks to traverse between upper and lower levels of the winery, and all associated drainage.


  • Sloping section adjacent to a large storm water channel, and final design needed to incorporate several flat areas and vehicle manoeuvring paths.
  • Short timeframe.

Challenges met:
Worked collaboratively and effectively with the structural engineers and Council.

A cost effective, smart design solution provided for both pavement and private drainage.

51 Lot Intensive Residential Development

  • Consent essentials and client goals met.
  • Appeased all concerned parties.


This multi-unit residential development consists of 8 two bedroom social housing units. With difficult ground conditions and a tight site, a collaborative approach from the Geotechnical, Structural and Civil teams enabled us to be proactive in addressing a variety of construction issues.

These issues were often identified during inspections and working collaboratively enabled us to discuss the issues in-house and provide immediate feedback and design changes to implement onsite.

Old stormwater reticulation re-established as a natural stream.


  • Constrained and large scale earthworks.
  • Environmental controls to prevent pollution during construction.
  • Complex stream with steep terrain.
