Bridgedoctors offers cost-effective and sustainable bridge inspection and bridge assessment services. We have a thorough inspection regime, recording of structural defects and understanding of the deterioration of bridge components.
Our team have conducted thousands of bridge inspections across NSW. We provide Level 1 and Level 2 bridge inspections. Bridgedoctors work with a range of engineers throughout NSW in the provision of Level 3 inspections.
LEVEL 1 INSPECTIONS
Level 1 inspections identify general maintenance required for all types of bridges.
LEVEL 2 INSPECTIONS
Level 2 inspections are conducted in accordance with Transport for NSW practices. Level 2 inspections include road & rail bridge, wharf, culvert, pipe and sign gantry inspections. All types of timber, concrete, steel and composite structures are included in our Level 2 inspection regime.
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 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:
We have worked in the quality team on the highly successful Ballina Bypass Alliance Project. Bridge Doctors personnel are experienced in achieving above industry standards for elements of bridge construction.
Drawing reviews, material management and construction supervision can be provided. We focus on quality control strategies including preparation of works prior to construction, process improvement and enhancing safety awareness. Bridge Doctors can work with companies to ensure the construction quality of bridges.
Microbat Habitats – In collaboration with an EcoLogical Australia ecologist, we designed and installed permanent microbat roosting habitats under bridge sized structures.
Weather Stations – Installation and demobilisation of automated water quality stations at Emigrant Creek and Skinners Creek on the T2E project.
Woolgoolga to Ballina Project – Woolgoolga to Ballina was the final link in the Pacific Highway, between Hexham and the Queensland border, to be upgraded to four lanes.
On completion of bridge and culvert construction on this project Level 2 handover inspections were carried out on 255 bridges and culverts according to TfNSW Bridge Inspection procedures.
Notable bridges included:
Transport for NSW (TfNSW) – Specialised inspections of select bridges and bridge elements, including entry of inspection data into TfNSW’s Bridge Inventory System (BIS).
Bearing Inspections – Irving Bridge, Casino Jenny Constable Bridge, Wiangaree, Missingham Bridge, Ballina and Murwillumbah Bridge, Murwillumbah. Over 5 days bearing inspections were conducted using a MOBI truck. Traffic control and night work were involved.
Detailed Level 2 Inspection – A 4-day inspection of the Grafton Road Rail Bridge involving road closures and an EWP mounted on a river barge.
Detailed Level 2 Inspections– Bawdens Bridge, Glenreagh Bridge, Genreagh, and Pollocks Bridge, Jackadgery. Inspections involved work from an underbridge inspection unit and EWP.
Transport for NSW (TfNSW) – Level 2 inspections from 2010 onwards on over 400 bridges annually, within the northern Region of NSW. The inspections provided cost effective and sustainable bridge asset management for TfNSW by having a thorough inspection regime, recording of structural defects and understanding of bridge components.
The inspections and reporting complied with TfNSW Bridge Inspection procedures. Inspections included organising access to sites access to all sites and liaison with Government Departments, Public Utility Authorities, landowners and the general public.
Port Stephens Council –Level 2 inspections and reports of Council’s road and pedestrian bridge asset portfolio. These inspections assisted PSC to ensure asset management in a financially sustainable way and represented a substantial savings for PSC.
National Parks and Wildlife Services – Level 2 inspections and reports of 19 vehicle bridges as part of NPWS ongoing asset management. The bridges varied in size and structure from single span log bridges to multi span timber, steel and concrete structures. Some bridges were located on 4WD trails with restricted access.
Taylor Rail Australia – Level 2 inspections and reports on 30 rail bridges and culverts on various rail networks.
Transport for NSW (TfNSW)- Drive-by inspection of flood damage to bridges in northern NSW following the 2020 floods.
Reports contained the location of damage from flood debris deposits, erosion and scour around bridge foundations. Photographic records were included. Reports were was used by TfNSW to organise repair works.
