PMHC – Bridge Assessment Program.
Client.
Port Macquarie Hastings Council
Location.
Port Macquarie, NSW
Project Description.
Port Macquarie Hastings Council (PMHC) wanted a better understanding of the heavy vehicle operational capacity for its Timber and Concrete Bridges. Ductile Consulting Engineers was engaged to assess 36 timber and 55 concrete bridges.
Our Role
- Updated utilisation ratios on 29 previously assessed timber bridges
based upon updated timber surveys; and completed Tier 2 assessments
on an additional 7 timber bridges - Performed Tier 1-2D assessments on 40 concrete bridges
- Reviewed 15 previous for consistency with current project
- Developed network level assessments of the heavy vehicle capacity
and management recommendations for access
Value Delivered
Through the use of our assessment automation tools, we were able to provide fast, quality, assessments at a reasonable price. Through our dashboarding and engineering experience in interpreting assessment outcomes, we were able to provide clear, high-quality recommendations for heavy vehicle access across PMHCs bridge network.
Funding: Restart NSW – Fixing Country Roads Program
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.
Orlando St Bridge Level 3 Inspection
Routine inspections of the Orlando St Bridge revealed significant deterioration, leading to Ductile Consulting Engineers being engaged. Their analysis confirmed no load restriction was needed and informed repairs to extend the bridge’s life by at least 30 years at a fraction of replacement cost.
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.
