International Road Federation, a Geneva based global body working for safer and better roads and safe mobility world wide expressed concern at the collapse of the foot over bridge in Mumbai. In similar incidents in the recent past where lives were lost, the IRF had stressed on the need for carrying out Inventory and Condition survey of all bridges and culverts on rail and road networks, presently being maintained by State Government agencies including Municipal Corporations, Public Works Department and civic agencies as a precautionary measure.

Mr KK Kapila, Chairman IRF, said that “The Union Ministry of Road Transport and Highways (MoRTH) and the National Highway Authority of India (NHAI) have already appointed consultants to carry out Inventory andConditions survey of bridges and culverts (for updating the Bridge Management Survey (BMS) on existing highways and roads. The Ministry of Railways, State Governments in the country and Municipalities should be proactive when it comes to safety of vehicles and pedestrian bridges affecting public life.”

Mr Kapila said that “Worldwide, the Inventory and Condition survey is carried out regularly with focus on the structural safety of large bridge structures such as vehicular bridges which are Six meters (20 Feet) or more in length to ensure that these bridges are structurally sound for vehicular traffic. As per the norms, a newly constructed or renovated bridge is inspected within 90 days of the bridge being opened to traffic and every 12 months throughout the lifecycle of the structure. The results of these mandated inspections provide information on the structural safety of the bridges and assigns each bridge a specific sufficiency rating that speaks about the overall health condition of every single bridge.”

He said that “Similar Inventory and Condition process should be carried out for bridges less than 20 feet, i.e. smaller bridge structures or pedestrian bridges, to lay the foundations of a good bridge maintenance programme based on quality inspection data, including complete and accurate information on the bridge structures and their individual aspects for the bridge structures falling in the purview of the Centre, State or a City agency, These structures need to be regularly inspected for 'Sufficiency' rating as per requirement of Bridge Inventory Standards.”

He added that “The sufficiency rating is a numerical rating between 0 and 100 given to each highway bridge. The value is based on a bridge’s structural adequacy and safety, essentially for public use, and its serviceability and functional obsolescence.”
