ASSET MANANGEMENT SYSTEM
Now being implemented by Government of India through Ministry of Road, Transport and Highways as Indian Bridge Management System.
Indian Bridge Management System (IBMS) is a National Bridge Management System that creates an inventory of all Bridge assets in our country and applies a technical logic to manage the asset during its life cycle. It generates detailed inventory data and ratings of all bridges every year on bi-annual basis to ensure that the dynamics of deterioration process are captured and attended to. This follows the dual principle of STICH IN TIME SAVES NINE and FIRST REPAIR WORST DAMAGE (FRWD).
IBMS was conceptualized in the form of IRC SP 35 way back in 1993 as a guideline to implement a bridge management system. Our Director Mr. Sachin Joshi has been working on the research of compilation of complete manual for implementation of Bridge management system for the past 10 years and the same was published in July 2014 as Bridge Asset Management Program (BAMP) at a round table held at Institute of Engineers Mumbai. The copyright for the same is with Mr. Sachin Joshi. Today’s IBMS draws its inspiration from the same document. IBMS has been developed indigenously and is being implemented by MORTH. Shri Niteen Gadkariji Minister for Road, Transport & Highways was presented with this concept in August 2015. The Minister announced the same in the E-Year book 2015-16.
Development of the system posed its own challenge as the system to manage asset had to be developed in a manner where the field studies could be conducted with minimum effort and in which maximum details could be collected. The volume of the database was also posing a challenge; it is anticipated that the overall data base will consist of over 150,000 culverts and bridge data. This is a huge volume to handle for a management platform. No other platform in the world has this size of database. Most platforms handle about few thousand bridges. The bridges had to given a unique identity number which was the first step of inventory creation. Then their precise location details in form of Latitude and Longitude had to be collected in an Auto mode using the Ground Positioning system. Once these details are collected, the engineering properties of the bridge design, material and other technical details of the bridge are being collected. These are essential components of inventory collection process. On completion of inventory data, the structural component rating is done using a 0 to 9 scale to define the status of various bridge components like Foundation, Piers, Super structure, Deck, Scour rating, waterway adequacy, structural status and also Socio- Economic parameter which decide the importance of the bridge in relation to its contribution to daily social and economic activity of the area in its immediate vicinity.
PROCESS OF INSPECTION:
Based on this inventory and ratings codes, IBMS analyses the data and indicates the bridges which need further investigation which is in-depth or detailed study using various non destructive testing (NDT) procedure. The initial inventory and rating codes generates the deterioration process prognosis which is validated by the NDT procedures. A detail remedial plan is then defined for each bridge tested; which is based on the standard specifications for Repair, Rehabilitation and Strengthening of Bridges.
PROCESS OF PRIORITY AND RANKING OF BRIDGES:
Ranking of bridges for repair is driven by a logical protocol which is based on the cost of repair, the importance of the bridge in Social and Economic scenario and the level of deterioration defined by the ratings as defined by Structural Rating number used in conjunction with the traffic on the bridge and age of bridge. The ranking module of IBMS defines a list of bridge that need to be repaired/ retrofitted as per priority and can be taken up based on total fund available with the Ministry. This brings in technical and socio-economic logic to the sequence of bridges to be repaired.
PPMP: Power Project Management Program is a management tool for one individual power plant. It is a standalone system. Power plants are of various types and each type has unique movement of material that culminates into a process (Eg Coal process in Thermal plant, Water process in hydel plant).
Unique identifiers are used to define the structure to be managed. Critical components have been identified in each of the type of power plant and accordingly proper importance is provided to these components.
Based on the information gathered in this study, RIM (Routine Inspection and Maintenance) Module and DIM (Detailed Inspection and Maintenance) Module are defined. Each of the action within the module is specific and has a suggested frequency for its application. The frequency of the each activity in RIM and DIM module ensures that all distress symptoms are attended to before they reach critical point.
Tall structures like chimney are accorded special inspection attentions as any remedial measure is very expensive due to approach cost involved. Water conducting tunnels are also accorded special inspection frequency as they cannot be inspected visually during movement of water in the tunnel.
PPMP is restrictive to the civil engineering aspect of the structures. Mechanical and electrical components of the structure are not governed by this program.
MAMP: Marine Asset Management Program has been evolved to be applied for the entire port complex or for various marine structures located in a specific geographic area. This program accounts for the hostile marine environment that the structures are exposed to.
As in all Asset Management Program, in MAMP each of the assets is classified as per their location, type, structural capacity, marine importance, etc. All these unique identifiers define the structure to be managed. This classification can be limited to one single port area, or to multiple ports or individual structures in multiple port locations.
Based on the information gathered in this study, the next stage of Asset Management Program in evolved. This is definition of RIM (Routine Inspection and Maintenance) Module and DIM (Detailed Inspection and Maintenance) Module. Each of the module is specific and each of the action has a suggested frequency for its application. Specific problems faced in marine environment calls for specific remedial measures, which are defined and specified based on the inputs of the inspection study. The frequency of the each activity in RIM and DIM module ensures that all distress symptoms are attended to before they reach critical point.
MAMP addresses all types of marine structures like Jetties, wharfs, dry docks, berths, approach channels, levies, breakwaters, slipways etc.
This program is restrictive to the civil engineering aspect of the structures. Mechanical and electrical components of the structure are not governed by this program.
Airport Asset Management Program has been evolved to be applied for the entire airport complex or for various structures located in a specific airfield area. This program accounts for the dynamic loading and aircraft movement related stresses in any airfield structures.
Unique identifiers are used to define the structure to be managed. This definition is limited to one single airfield area. In this respect the AAMP defers from other AMP's. The classification takes into account if the component of the airfield is used by aircrafts or by passengers.
Based on the information gathered in this study, RIM (Routine Inspection and Maintenance) Module and DIM (Detailed Inspection and Maintenance) Module are defined. Each of the action within the module is specific and has a suggested frequency for its application. This documents takes into account the regulations specified by ICOA, AAI, FAA.
The frequency of the each activity in RIM and DIM module ensures that all distress symptoms, wear and tear symptoms like rubber deposition, etc are attended to before they reach critical point.
AAMP deals with all structures in a designated airfield including and not limited to apron, parking bays, terminal and cargo complex, hangers, taxiways, runways, drains. This program is restrictive to the civil engineering aspect of the structures. Mechanical and electrical components of the structure are not governed by this program.
