3-D Modelling and CAD Design

Tonkin & Taylor’s computer aided design (CAD) capabilities have continued to expand in response to client needs for specialist services in the infrastructure (road, rail and tunnelling), land development and solid waste sectors.

T&T has an impressive track record in these areas, having had a significant input into high profile projects such as SH 20/20A extension to Mangere Airport, Vector tunnel, Northern Gateway (Albany to Puhoi motorway extension) and Redvale Landfill to name a few.

Alignment Design

Design and 3D modelling of alignments include the geometric design of roads (urban, rural and service roads), rail, tunnels, canals, pipeline networks (stormwater and sanitary sewer), and
retaining walls.

12d Model is the principal design software used for these types of projects.

Land Development

The design of land development projects includes landfills (solid waste), quarries, housing subdivisions, commercial development, dams (Water supply and power generation).

Land Development Desktop (LDD) is the principal design software used for these types of projects.
