 | Charles Webster - North East Maintenance Alliance Manager, DM Roads. Charles will be speaking on the 2022 Victorian Flood Response – Regional Roads Victoria Hume Region. Charles Webster is the Alliance Program Manager for the North Eastern Maintenance Alliance (NEMA), which manages the VicRoads (Department of Transport and Planning) network in North East Victoria. He has been in the alliance for the past 3 years delivering the annual works program with maintenance and capital works projects. Throughout this time, he has strengthened the project governance component of project delivery through stronger adherence to systems and by providing more transparent reporting of key project metrics to key stakeholders. In October 2022 Victoria experienced extensive flooding, particularly across the Northern and North East regions of Victoria. The flood required a significant initial response to manage the large amount of road closures that needed to be implemented. Close coordination occurred with emergency services during the acute stages of the flooding as well as mobilising a large workforce at short notice to deal with the response. After the initial response, the team focused on recovery and rectifying the damage that occurred across the 4,000km network. Charles has extensive experience delivering both large and small civil infrastructure projects over the past 15 years in Victoria. Prior to working within the DTP alliance he has worked on a large array of major projects, including scopes related to bridge, rail, pavement, utility relocation and earthwork and retaining wall construction, primarily in brown field urban environments. He started his career in the precast concrete industry supplying engineered precast concrete products to the Melbourne market before joining contractors to deliver some of Melbourne’s major projects. Charles has a passion for efficient and cost-effective delivery of projects focusing on strong proactive planning to minimise construction disruption and ultimately lead to safe, high-quality projects being delivered quickly. |
