Bridge Inspections

Level 1 Inspections

These inspections identify general maintenance required for all types of bridges.

Level 2 Inspections

Level 2 Road & Rail Bridge, wharf, culvert, pipe and sign gantry inspections. Inspections are conducted under the NSW Roads and Maritime Services “Bridge Inspection Procedures” and associated specialist training and apply to all types of timber, concrete, steel and composite structures. The structures are broken down into individual elements and each element is rated on the observed condition at time of inspection and an assessment of the overall structure is obtained from the sum of the element conditions with emphasis on critical elements.

Level 3 Inspections

Bridgedoctors can accompany and support a structural engineer during Level 3 inspections. We work with a range of engineers throughout NSW. As part of the Level 3 inspection Bridgedoctors undertake a visual inspection and rate bridge elements in accordance with procedures for Level 2 inspections. Reports are provided by the accompanying engineer and include recommendations concerning future management options.

During a Level 3 inspection diagnostic testing can include:

  • Cement content
  • Chloride concentration
  • Compressive strength
  • Concrete resistivity
  • Covermeter surveys
  • Die penetration testing
  • Delamination surveys
  • Half-cell potential
  • Lead paint assessment
  • Magnetic particle testing
  • Schmidt hammer

IndependEnt Assessment & Verification

  • Precast concrete girders and planks
  • Box culverts
  • Pipe manufacture
  • Verification of design drawings and specifications for all concrete, steel and timber bridge types and components
  • Constructability reviews

  • Environmental projects

The Bridgedoctors worked closely with Eco Logical Australia recently on a project that required alternative roosting habitat for threatened Bentwing Bats to be created as part of the Pacific Highway upgrade. Kevin and his team provided valuable assistance in the design and planning stages of the project to install a new style of bat box in a Pacific Highway culvert. The Bridgedoctors were very responsive to design changes, adjustments to the installation methodology and constraints related to the use of existing highway infrastructure and working within a difficult environment. The new style Bentwing Bat box constructed from hebel blocks was installed by Kevin and his team within the project timeframes and with the complete satisfaction of Eco Logical Australia. Eco Logical Australia highly recommends the Bridgedoctors for any bridge and culvert related projects.
