Roadside Barrier Installation and Maintenance Issues: The Need for Improved Quality Control

This paper aims to raise awareness of the need to improve installation and maintenance practices and quality control associated with both permanent and temporary road safety hardware. In 2011,the Roads Corporation of Victoria (VicRoads) was approached by barrier installation companies and product suppliers with serious concerns for practices the industry were engaging in that are likely to compromise the performance of safety hardware. Over a 12-month period, VicRoads randomly inspected a number of routes that received large quantities of permanent barriers (mainly guard fence and wire rope safety barrier (WRSB)) because of the presence of roadside hazards. By the end of the 12 months they had seen considerable evidence to realize the concerns raised were valid and worth taking action on, not only of permanent barrier systems but also of temporary worksite barriers used during construction. Typically hardware was not installed in accordance with both VicRoads’ specification requirements and the licensed product suppliers’ requirements .Following the investigation, VicRoads introduced a short-term governance measure to immediately address the issue going forward. As part of its contracts, VicRoads introduced and still currently requires any installation of guard fence terminals and WRSB systems to be certified by the Australian licensed product supplier prior to the issue of Practical Completion on the contract.This has delivered some success and improvement. However, many compliance audits are still highlighting the problem that remains. VicRoads is currently investigating strategies to address existing installations that are outside the contract defects period and that involve longer-term solutions to addressing the problem. The author concludes that the benefit the community receives from the investment in road safety barriers and devices could be considerably increased if there was investment in ensuring those who design, install, and maintain such systems have been adequately trained and accredited to do so.
