Level 2 Bridge Inspection
‣ Bridge authorities are responsible for bridge networks
‣ To maintain the structures, a Bridge Information System (BIS) or Bridge Management System (BMS) is essential
‣ Without consistent and accurate bridge condition assessment, reliable BMS outcomes could not be expected
‣ For precise bridge condition assessment, inspection service providers should recognise the fundamental limitations of the current Level 2 Bridge Inspection

Inspection Procedures
• The qualified inspector will conduct a inspection.
• The inspector will evaluate a condition rating for each individual structural element based on the standard Level 2 Inspection procedure.

Limitation of Level 2 Bridge Inspection
‣ Although current routine bridge inspections are required to be carried out by certified inspectors, some major issues have been identified: ‣ Visual inspections are subjective and not always reliable ‣ The manual inspection process is time-consuming and costly ‣ A number of safety risks are associated with bridge inspectors
‣ To minimise these limitations, enhanced asset management technologies are significant: ‣ SIAMA is developing an advanced Level 2 bridge Inspection method
‣ Using an Unmanned Aerial Vehicle (UAV) and an Unmanned Ground Vehicle (UGV) in order to collect high quality image data
‣ Using image processing techniques to analyse precise condition status

Innovative Bridge Inspection Technology
‣ Step 1: The still images of the bridge components to be assessed are collected using a high-resolution digital camera via the UAV, UGV or mini crane & rail system
‣ Step 2: The captured images are classified based on the element’s identification and location on the bridge. SIAMA’s image processing techniques will be applied to detect various structural defects
‣ Step 3: The evaluated condition state of each element is used to generate the Level 2 Inspection report form (by SIMS Bridges)

Unmanned Ground Vehicles (UGVs)
‣ SIAMA’s remote controlled mini UGV is capable of conducting autonomous culvert inspections in confined spaces as low as 1.2 metres in height.
22
SIAMASmart Infrastructure Asset Management AUSTRALIA
Smart Infrastructure Asset Management Australia Research and Development Pty Ltd
Unmanned Ground Vehicles (UGVs)‣ The UGV utilises the same state-of-the-art
scanning and positioning system employed by SIAMA’s UAV to navigate and capture 360-degree surface imagery of the entire length of the culvert.
‣ These images are then paired with distance measurements captured by the UGVs laser sensors to identify and record the exact position of a specific defect.
‣ SIAMA’s UGV system also allows the entire surface of the culvert to be accurately recorded and analysed while maintaining a safe and secure work environment for staff, by eliminating the issues associated with operating in confined spaces. 23

High-tech Data Analysis and Management
SIMS Bridges utilises the bridge component condition rating data outputs of SIAMA’s Smart Image Processing Technology (SIPT), to conduct current and future bridge performance analysis at a component, project and network level.
Alternately, asset owners can access the data analysis and Maintenance, Repair and Rehabilitation reporting outputs of SIMS Bridges utilising their own in-house asset inspection and condition rating data.
SIMS Bridges condition rating data assessment and reporting outputs assist asset owners to transition from reactive Maintenance, Repair and Rehabilitation (MR&R) activities towards more cost effective and proactive bridge maintenance strategies.
