Maintaining Subway Infrastructure Using BIM

The performance of subways is facing a lot of problems due to its age and lack of proper asset management planning. Many components in subways are deteriorating and their functionality is drawing back. Negative environmental impacts are uprising now which are represented in energy consumption and utilized materials in subways. There is a real need to develop a system that can measure the level of service and determine the key performance indicators. The system shall take into consideration prioritizing objectives to maintain certain level of service, the allocation of available budget and mitigation of negative environmental impacts. Before the emergence of the BIM (building information models) technology, CAD (computer-aided design) files were used by facility managers to perform facility/asset management. However using CAD files in facility management had some problems like lack of information integrated within the CAD drawings, lack of coordination between different specialties and the complexity to interoperate other software. This paper proposes the application of BIM in subways by modeling different components including structural, mechanical, electrical, and HVAC (heating, ventilation, and air conditioning). Each component is associated with its probabilistic deterioration model. The proposed system aids facility managers in rehabilitation decisions, taking in consideration priorities of objectives and budget allocation.
