The total expenditure on bridge maintenance/rehabilitation and improvement for the year 2010-11 in Australia was AUD1.2 billion. This was a 67% rise in ten years. The efficient use of public funds for the structural integrity of bridge networks requires an effective bridge asset management technology. For effective asset management, many bridge authorities have implemented Bridge Information System (BIS) or Bridge Management System (BMS) to manage their routine inspection information.

The efficient use of public funds for the structural integrity of bridge networks requires an effective bridge asset management technology. For effective asset management, many bridge authorities have implemented Bridge Information System (BIS) or Bridge Management System (BMS) to manage their routine inspection information. The success of a BMS is highly dependent on the quality of bridge inspection results and accurate estimation of future bridge condition ratings. To ensure such successful outcome, a BMS must (1) contains reliable, consistent and accurate condition data from routine bridge inspections; and (2) encompasses a reliable deterioration modelling that overcomes the shortcomings of lacking historical bridge inspection records. However, without consistent and accurate bridge condition data, reliable BMS outcomes would not be expected regardless of superiority of asset management techniques. Although current routine bridge inspections are required to be carried out by certified inspectors to provide condition assessment, several limitations have been identified as demonstrated in published literatures. They include: (1) visual inspections are subjective and not always reliable; (2) entire manual process is costly and time-consuming; (3) a number of safety risks are associated with filed inspectors; (4) inspection requires experienced and highly trained personnel – now most bridge authorities are facing the issue of shortage of required level of inspectors.
