Project Summary


Project
Nagpur, the second capital of the state of Maharashtra, is experiencing a surge in economic activity and city growth, prompting a boom in infrastructure development. Increased traffic on city roads, and a public transportation system only constituting 10 percent of all travel in the city of Nagpur, has significantly impacted this financial upswing. Most commuters use motorized two-wheeled vehicles, resulting in traffic congestion, pollution, and accidents. Maharashtra Metro Rail Corporation Ltd. (Maha Metro) was hired to create a safe, dependable, commuter-friendly, and environmentally-sustainable rapid public transport system for the Nagpur metropolitan region. Expected to be completed by December 2019, Nagpur Metro is a 41.7-kilometer railway project, which includes 40 stations and two depots, divided into two corridors: North - South and East – West.

Solution
Maha Metro deployed a digital project management system, developed through Bentley’s OpenRail Connected Data Environment (CDE), which includes the combined capabilities of ProjectWise and AssetWise and covers planning to performance stages of the asset lifecycle. Maha Metro’s OpenRail CDE is customized for multiple users and incorporates documents and drawings from the organization itself as well as data from external consultants and contractors within its supply chain. As part of Maha Metro’s digital project management system, the organization is developing its Asset Information Management System as a synchronized arrangement for effective operations and maintenance. Combining documents, engineering and maintenance data, plus 3D models from disparate sources, the system is being used during construction to link all the project information via a tagging system for its assets. Following completion, these deliverables will be stored and maintained as source of trusted information that forms the basis upon which decisions will be made during the operation and ongoing maintenance of the railway’s infrastructure.

Outcome
Using OpenRail Designer (formerly Power Rail Track) during the project delivery phase enabled the team to optimize depot design by shortening the track length by 6 kilometers and halving the bay line length to 80 meters, resulting in a savings of USD 15 million. In addition to a further anticipated savings of USD 400,000 through the avoidance of data loss throughout the process, Maha Metro used clash detection capabilities within OpenRail to identify and resolve issues during the design phase prior to construction, avoiding costly rework estimated to cost USD 60,000. During the operational phase, Maha Metro’s asset management solution will help extend the useful life of its assets, enhance performance, conserve energy, ensure the safety of the traveling public, and ultimately lead to a reduction of accidents on its roads. By ensuring this trusted information remains current and accessible, the system enables strategic decision making, establishing condition-based monitoring and progressing toward predictive maintenance strategies. As a result of these benefits, reliable railway operations are estimated to save at least USD 222 million over 25 years.

Software
Bentley software is being used to establish a connected data environment in the planning and design phases, storing the digital models and assets in a central location, and to establish an asset management system. Maha Metro’s implementation of Bentley’s OpenRail solution uses iModels as the final delivery model due to its ability to provide the organization with reliable, long-lasting asset models for reference. Within the OpenRail CDE, AssetWise is configured to record all data spanning every lifecycle stage, with asset tags used to link Bentley applications with other software. This interoperability allows documents and asset information to be linked to 3D models.

Outcome/Facts
  • 500,000 point and linear assets, distributed among 12 categories, will be managed over time through Bentley’s OpenRail CDE.
  • Maha Metro expects to save USD 400,000 through the avoidance of data loss alone, and an estimated USD 222 million over 25 years of operations.
  • Clash detection capabilities helped identify and resolve issues in the design phase prior to construction, avoiding costly rework estimated to cost USD 60,000.
