Trenchless Technology Used to Understand Risk Under New Major Road

Abstract

Managing buried assets and risk is becoming more optimised with the advent of trenchless technologies to assess their condition. The Queensland Department of Transport and Main Roads has recently utilised innovative technologies and techniques to help understand the condition of a critical buried water main, to assess the risk of building a roadway over the pipeline. While traditional methods could have been employed, the asset’s criticality deemed it a high-risk, thus managing the risk was key to delivering a successful project. This paper describes the project background, pipeline and method employed to manage risk of the project.
