One of the worst infrastructure tragedies is bridge failure. Ageing and deterioration of bridges can lead to structural and/or functional failure. Since transportation infrastructure has a huge impact on sustainable development, bridge failure is one of the most serious infrastructure issues that frequently occur in every nation. In the construction industry, bridge failure is likewise seen as a significant problem that has considerable negative effects on society, the environment, and the economy because it can result in accidents, fatalities, and extensive property damage. However, the lack of sustainable management may be the real cause of this kind of bridge failure. Thus, it is important for the authorities to carry out an effective bridge assessment method to ensure the safety of the bridge condition and maintaining its life span. Structural health monitoring (SHM) is one technique that could be used to operate and undergo the assessment of the bridge’s structure. SHM is used in the building system not only to detect structural issues/damages and ensure public safety, but also to reduce the economic costs. The study’s objectives were to ascertain SHM’s contribution, evaluate its effectiveness, and highlight its significance in the bridge assessment process. These factors were assembled into a questionnaire survey that was distributed among stakeholders, e.g. clients, consultants, and contractors. Next, the data recorded through the survey were analysed using SPSS software to achieve the desired objectives. The majority of respondents concurred that SHM’s primary contribution to bridge evaluation is that it incorporates risk reduction, enhanced structural system safety and dependability, sustainability, and life cycle reduction. Besides, respondents also agreed that SHM implementation in improving the assessment of existing bridge conditions as the bridge structure would be in better state by referring to the bridge rating index. The significance of SHM implementation was also highlighted, with the major significance of SHM being the capacity to analyse the status of the bridge to determine whether it is in great or poor state. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
