    Overview of the Bridge and Key Parameters<\/u><\/strong><\/p>

    \u00a0<\/strong><\/p>

    • Bridge Overview<\/strong> and structural status: <\/strong><\/p><\/li><\/ul>

      \u00a0<\/strong><\/p>

      The Bridge under review represents a typical bridge structure. The geometrical parameters assigned are typical. The bridge spans 300 meters with six 50-meter spans, supported by a pile foundations. Age assumed 33 years, and the location near the coast. It serves a critical role in regional transportation by connecting key economic hubs. Designed for high traffic, it accommodates four lanes and is a typical 70R [As per IRC load ratings] capacity bridge. Geospatial details ensures accuracy of location and enables detailed evaluation of geographical impact.<\/p>

      \u00a0<\/p>

      The bridge is located near the coast, thereby has prolonged exposure to environmental impact causing very high probability to corrosion and carbonation. Age related exposure to mechanical stresses, as overloading and fatigue are visible in the bridge structure.\u00a0 Historical narrative in the form of four inspection data available in the report. Historical narrative provides valuable insight into the progression of deterioration and reduction of Balance service life. Bridge Structural Ratings identify the location of increasing deterioration. In the report, observed that ratings for three of the four components are increasing with ratings for superstructure increasing to very severe distress levels. The overall increasing ratings indicates distress cause, which is due to location and geometrical parameters of the bridge. Scrutiny of Cause Matrix ratings confirm our judgement. Corrosion and Carbonation ratings observed to be increasing. Since the bridge is aging symptoms of overloading and fatigue are visible. Cause matrix ratings for these two causes confirm the same. Since the bridge is beyond 50 percent of designed service life [50 years], Short-term structural health monitoring deployed also indicates reduction of performance. All three parameters [Symptoms, Cause matrix and ST-SHM] are self-confirming increased deterioration.<\/p>

      \u00a0<\/p>

      Evaluation of BSL and ABSL done in GABM post scrutiny of age of bridge. Age of bridge indicates the predominant factor affecting evaluation of BSL and ABSL. When the bridge is new and the age is less than 20 percent of Design service life, symptoms are critical factor. From 20 percent to 50 percent of designed service life, Cause matrix play a critical role in evaluation. Post this period, ST-SHM observation are essentially required for accurate analysis of BSL and ABSL.<\/p>

      \u00a0<\/p>

      GABM offers additional information regarding Median Service Life [MSL]. MSL definition is critical to understand how efficient rehabilitation intervention will function. If MSL evaluated is below the age of the bridge and the envelope of the two curves intersects prior to the vertical age line, efficiency of intervention will be lower. The report has various definitions relating to Functionality and Socio-Economic Impact of bridge to help decide feasibility of providing rehabilitation intervention. Efficiency of such intervention also provided.<\/p>

      \u00a0<\/p>

      • Structural, <\/strong>Functional and Socio-Economic Impact <\/strong>o<\/strong>f Bridge: <\/strong><\/p><\/li><\/ul>

        \u00a0<\/p>

        Over the years, the deck and substructure ratings have shown gradual changes, signaling ongoing deterioration even with targeted repairs. The superstructure experienced minor improvements, but persistent vulnerabilities highlight the necessity for continuous and comprehensive interventions to address long-term structural challenges effectively.<\/p>

        \u00a0<\/p>

        Study of Functional rating and Socio-Economic ratings help decision-making processes. The bridge geometry indicates satisfactory scenario relating to deck geometry and vertical clearance of the bridge. However, the waterway adequacy is not satisfactory and so also increasing Average Daily Traffic count [ADT] is a cause for worry.<\/p>

        Socio-Economic ratings indicate the importance of the bridge in the region and the impact of the bridge on economic stability and growth of the region. Increasing traffic causes higher environmental impact.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

        • Causes of Deterioration, Vulnerability, and Risk Indices<\/strong><\/p><\/li><\/ul>

          \u00a0<\/strong><\/p>

          1. Causes of Deterioration:<\/strong><\/p><\/li><\/ol>

            \u00a0<\/p>

            Chemical factors such as chloride attack and carbonation have progressively compromised the concrete matrix, weakening structural integrity. Mechanical stresses from overloading and fatigue, seen by the micro-cracking, affecting long-term durability. Environmental factors like temperature fluctuations, erosion, and abrasion have caused gradual wear but remain relatively stable over time.<\/p>

            \u00a0<\/p>

            To address these issues, advanced concrete restoration techniques can mitigate chemical impacts and enhance structural resilience to mechanical stress. Regular application of protective coatings, combined with real-time monitoring of stress and environmental effects, can minimize deterioration and promote long-term durability.<\/p>

            \u00a0<\/p>

            1. Geographical Vulnerability Assessment<\/strong><\/p><\/li><\/ol>

              \u00a0<\/strong><\/p>

              The susceptibility to natural hazards and structural risks evaluated through indices to assess flooding, cyclones, earthquakes, and landslides. This comprehensive assessment provides insights into the bridge\u2019s exposure and resilience, underlining the necessity of effective mitigation strategies.<\/p>

              \u00a0<\/p>

              Flooding:<\/strong><\/p>

              Flooding emerges as the most significant vulnerability, driven by the potential for water ingress and hydrostatic forces. These factors can compromise structural stability and accelerate material degradation.<\/p>

              \u00a0<\/p>

              Cyclones:<\/strong><\/p>

              Cyclones pose threat due to high wind loads, which could lead to structural displacement and damage to ancillary components, impacting overall functionality.<\/p>

              \u00a0<\/strong><\/p>

              Earthquakes and Landslides:<\/strong><\/p>

              The risks associated with earthquakes and landslides are comparatively lower, reflecting the bridge\u2019s robust design against seismic forces and the region’s minimal geological instability.<\/p>

              \u00a0<\/p>

              \u00a0<\/p>

              1. Global Analytics for Risk and Resilience Management [GARM]: <\/strong><\/p><\/li><\/ol>

                Effective risk and resilience management is critical for ensuring the longevity and functionality of infrastructure in bridges. This involves analysing sustainability, financial implications, and overall risk to guide strategic interventions.<\/p>

                The declining sustainability index highlights the increasing challenges in maintaining bridge operations without timely and effective interventions. This underscores the need for proactive measures to enhance operational efficiency and reduce long-term vulnerabilities. A consistently high financial impact index points to significant cost burdens associated with delayed maintenance and rehabilitation. This trend emphasizes the importance of timely investments in repair and upgrade efforts to mitigate escalating financial liabilities. The gradual rise in the risk index signals an increasing probability of partial or complete structural failure. This highlights the urgency of addressing underlying vulnerabilities through comprehensive assessments and targeted resilience strategies.<\/p>

                To enhance the resilience and sustainability of bridge operations, a comprehensive prevention and solution framework is essential. GARM provides such a framework. With Multi-Criteria Decision-Making [MCDM] processes evolved within GARM. Till recently, decisions taken are based on a single criterion of structural status. MCDM applies the criteria of structural health\/ status in combination with Risk assessment, Financial due diligence and Socio-Economic impact of the bridge on the region to evaluate the priority of fund allocation for rehabilitation interventions. MCDM uses the dual processes of Simple Multi-Attribute Rating Technique in junction with Analytical Hierarchy Process to evaluate which of the bridges in the set of 10 most critical bridges should funds be provided. Further MCDM also evaluates the financial benefits accrued due to the bridge to the region and compares the same with estimated cost of rehabilitation and resilience enhancement.<\/p>

                GARM integrates data from maximum of six GABM to provide total picture. Each bridge in these six GABM is listed and individual reports and results are available for viewing and printing.\u00a0 Results produced by GARM validate the importance of Risk assessment and MCDM.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
