Advanced technical solutions for scanning, measuring and modelling assets and environment

ICD are brownfields engineering specialists driving innovation in energy, resources and heavy industry. Our in-house Geospatial team conducts cadastral, civil & construction surveys, 3D laser scanning and drone inspection, both as part of larger ICD projects, and as stand-alone projects. Scan data can be integrated with CAD designs for enhanced designs and forms a basis for VR models.

Project

• verview

The reason for this presentation is to encourage other surveyors to participate in similar projects to produce positive outcomes for people adversely affected by bush fires and other natural disasters. Any Surveyor, at any time, anywhere in the world, after any natural disaster can repeat this project and achieve the same results.
