Project Description.
Port Macquarie Hastings Council (PMHC) manages over 2,500 major and minor culverts across its stormwater network. To support their understanding and management of their culverts, PMHC received a grant from the Disaster Risk and Reduction Fund via the NSW Reconstruction Authority to develop and implement a mobile risk assessment tool to; update condition data, assess hydraulic capacity to determine inherent risks and vulnerability, and prioritise future repair, renewal, or upgrade works for culvert assets.
PMHC engaged Ductile Consulting Engineers to; perform condition inspections and catchment hydraulic assessments on 160 culverts, develop risk assessment and prioritisation systems in consultation with PMHC, and provide insight into the condition of the network and top priority culverts.
Following the successful completion of this phase of work, Ductile Consulting Engineers were engaged to; train PMHC staff on culvert inspection methodologies and the mobile risk assessment tool, as well as conduct inspections of an additional 115 culverts.
Other Projects.
Gunnedah Shire Council – Data Collection Assessments
We combined Gunnedah Shire Council’s bridge and culvert inspections with NHVR SLGAAP data collection, reducing mobilisation costs and improving efficiency. The project delivered digital inspection records and condition data to support maintenance planning and long-term asset management.
Tamworth Regional Council – L2 Inspections
Ductile Consulting Engineers completed Level 2 inspections of 64 bridges and 122 major culverts for Tamworth Regional Council. Using a dedicated culvert inspection methodology, DCE delivered more cost-effective inspections with reporting tailored specifically to culvert assets.
PMHC – Bridge Assessment Program
Port Macquarie Hastings Council engaged Ductile Consulting Engineers to assess heavy vehicle capacity across its bridge network. Ductile evaluated 91 bridges and, using automated tools, delivered efficient insights and clear recommendations to guide access.
