Indian Bridge Management System

Ministry of Road Transport & Highways has inventorized 1,72,517 bridges/structures under Indian Bridge Management System (IBMS). These structures comprise 1,34,229 culverts, 32,806 minor bridges, 3,647 major and 1,835 extra-long bridges. Earlier there was no proper data available on these structures on the National Highways network.

IBMS- features:

  • Indian Bridge Management Systems developed to create an inventory of all bridge assets on the National Highways (NH) in India, and apply a technical logic to manage the bridge assets during its life cycle.
  • It generates detailed inventory data and condition ratings of assets, ensuring the dynamics of deterioration process are captured.
  • This dynamism, in the deterioration process guides the inspection and rehabilitation of bridges.
  • The system allows the users to assign priority to maintenance activity, based on the present condition of the bridge.
  • The progressive improvement of all bridge assets is ensured over a period of time, as worst bridges, are first rehabilitated and then the less damaged bridges.

Key Facts:

  • IBMS is the largest platform in the world owned by a single owner, with database that could exceed 1,50,000 bridge structures. So far 1,15,000 bridges have been inventorized, of which 85,000 are culverts and the rest are bridges.
  • During inventory creation each bridge is assigned a unique identification number or National Identity Number based on the state, RTO zone and whether it is situated on an National Highway, State Highway or is a district road.
  • Then the precise location of the bridge in terms of latitude-longitude is collected through GPS and based on this, the bridge is assigned a Bridge Location Number.
  •  Thereafter, engineering characteristics like the design, materials, type of bridge, its age, loading, traffic lane, length, width of carriage way etc are collected and are used to assign a Bridge Classification Number to the structure.
  • These are then used to do a structural rating of the structure on a scale of 0 to 9, and each bridge is assigned a Structural Rating Number. 
  • The rating is done for each component of the structure like integral and non integral deck, superstructure, substructure, bank and channel, structural evaluation, deck geometry, vertical clearance, waterway efficiency etc.
  • In addition to the structural rating, the bridges are also being assigned Socio-Economic Bridge Rating Number which will decide the importance of the structure in relation to its contribution to daily socio-economic activity of the area in its vicinity.
