Orlando St Bridge Level 3 Inspection
Client.
City Of Coffs Harbour
Location.
Coffs Harbour, NSW
Project Description.
Routine inspections of the Orlando St Bridge identified significant spalling
and deterioration in the tidal zone. The City of Coffs Harbour engaged
Ductile Consulting Engineers to assess the damage and provide expert
advice for the management and remediation of the structure.
Our Role
- Undertake detailed NDT, sampling and laboratory testing;
- Undertake a load rating assessment to determine the remnant
capacity of the structure; and - Recommend suitable repairs.
Value Delivered
Through our detailed assessment, we were able to justify not imposing a load restriction on the bridge. Working with our project partner, Remedial Technology, we were able to specify a range of remediation techniques, including impressed current cathodic protection, to extend the life of the bridge by at least 30 years at a fraction of the replacement cost.
Other Projects.
Level 3 Structural Assessment – Walcha Council
We undertook a Level 3 structural assessment of G R Hicks Bridge, evaluating its load-carrying capacity and investigating concrete deterioration. We provided recommendations for targeted repairs, heavy vehicle access and ongoing asset management to support the bridge’s long-term serviceability.
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.
Level 3 Investigation – Wallamore Road Culverts
We investigated deterioration of two culverts on Wallamore Road at Boltons Creek and Savages Creek. The project involved condition inspections, structural capacity assessments and evaluation of remediation options to support informed asset management and maintain access.
