Overview
The Australian Tunnelling Society and Institution of Civil Engineers invite you to an evening of knowledge sharing, Q&A, and networking.

New Era of Tunnel Inspection
In the past, tunnel inspection and documentation was a “camera and clipboard” manual process to document geology, tunnel lining conditions, or assets within tunnel networks. It was time-consuming and inconsistent in terms of objectivity, continuity and spatial context.

With a variety of fixed and mobile platforms, we are now able to combine laser scanners and high-resolution cameras to rapidly record the tunnel surface to a resolution that can detect sub millimeter cracks.. Mobile systems can capture data at ambient traffic speed, reducing what
used to take weeks and months, to just hours.

From this data we then generate highly precise true-colour, textured 3D models of the scanned tunnel surface.

Detection, mapping and measurement of tunnel components can be undertaken in a centralised structured database, managing inspection intervals and temporal changes from a single point of truth.

Digital tools enable productivity improvements through the life of an asset, 3D Reality Capture Systems are an excellent example of this.

Experienced professional Senior Surveyor with an MBA in Project Management. Drew has worked across a number of different sectors including civil, mining, rail and infrastructure projects. For the last 15 year Drew has predominantly work on infrastructure projects in the UK and Australian with a focus on Instrumentation and Monitoring and Geospatial Capture. Drew is passionate about embracing new geospatial data capture techniques that can add value to key infrastructure assets by consistently monitoring change over time.

During his time in the UK Drew also worked of Western Section of Crossrail for over 4 years both on the contract side as a I&M Project Managing and, on the client, side overseeing the instrumentation and monitoring contracts, managing stakeholder interfaces and coordinating damage claims with assessors and insurers.
