Specialist Survey
Services

We operate where precision matters most — from high-voltage substations to mountain terrain roading and complex civil infrastructure.

01

Power Substation Surveys

Survey control, as-built documentation, and site layout for high-voltage substation construction and upgrades. Safety-compliant and commissioning-ready.

02

Engineering Surveys

Topographic, control, and set-out surveys for major infrastructure projects — supporting design through to commissioning.

03

Roading & Highway Surveys

Alignment surveys, cross-sections, and as-constructed data for road projects of all scales — rural tracks to major state highways.

04

Bridge & Structure Surveys

Deformation monitoring, as-built surveys, and structural set-out for bridges, culverts, retaining walls, and civil structures.

05

Topographic & DTM Surveys

High-resolution terrain modelling for design and planning. Drone-assisted capture for large or inaccessible sites with precision accuracy.

06

GPS & Control Networks

Geodetic control networks and GNSS surveys for infrastructure corridors, transmission lines, and remote access projects.
