Redvale Landfill, Dairy Flat, Auckland

3D Modelling - Land Development

Tonkin + Taylor’s computer-aided-design (CAD) team continues to expand to meet client needs and expectations. We offer specialist design services for infrastructure, land development and solid waste sectors. 

Our strong track record in these areas includes delivery of significant contributions to many high profile projects.

These include the SH20/20A Extension to Mangere Airport, Northern Gateway (the Albany - Puhoi motorway extension), along with Auckland’s Vector Tunnel, and Canterbury’s Kate Valley and Redvale Landfills.

Our CAD team has a high level of technical expertise and a strong team culture. This ensures we provide efficient and productive services.

Industry standard, up-to-date software is used to produce alignment (or string-based) design and land development (or terrain modelling).

Land Development

T+T has completed a variety of land development designs, including solid waste landfills, quarries, housing subdivisions, commercial developments, and dams for water supply and power generation.

AutoCAD Civil 3D (C3D) and 12d Model software are primarily used for these types of projects.

Key features of C3D software for land development design include:

  • Full AutoCAD integration
  • Terrain modelling and calculation of volumes for cut-and-fill
  • High-quality rendered image production for presentations and photomontages
  • Data transfer between C3D and 12d Model for design and integration of roading and stormwater components

Key features of 12d Model software for land development design include:

  • Terrain modelling and volume calculations for cut-and-fill
  • Rapid production of sections, and cut-and-fill plans
  • Data transfer between 12d Model and MX Road for design and integration of major roading and stormwater components

Some of our recent land development projects where C3D and 12d Model have been deployed include:

  • Redvale Landfill – 20 Mm3 capacity
  • Kate Valley Landfill – 11 Mm3 capacity
  • Silverstream Landfill (Stage 2) – 5.3 Mm3 capacity
  • Whitford Landfill
  • Westfield Albany Shopping Centre earthworks design
  • Botany Town Centre earthworks design
  • Hobsonville Point schools earthworks design
  • Waterview Connection design of playing fields, carpark areas and stormwater detention
