  • Delhi Metro (India)

    Sector Railways Project Type Urban Railway for MRT Project Title General Consultancy Service for Delhi Mass Rapid Transport System Project, Phase 1, Phase 2 and Phase 3 Location Delhi, India Client Delhi Metro Rail Corporation (DMRC) Project Period July 1998 March 2006 (Phase 1), July 2006 - June 2012 (Phase 2)

    As India's first modern metro rail project, Delhi Metro is perhaps the most successful urban infrastructure project in the nation Problem Addressed by the Project New Delhi has grown at a fast pace ever since it was founded as the seat of Indian government in 1912. In modern times, explosive growth of the population and increasing rates of vehicle ownership in the city has intensified traffic congestion and air pollution caused by emission.

    Delhi Metro Rail Corporation (DMRC) was created by the Government of India and Delhi City to construct and operate the metro system. A master plan for the metro network of eight lines totaling 245 km was drawn up to be implemented by 2021.

    In September 1996, the Government of India approved Phase 1 of the project for construction of the priority rail corridor. With no pause after the first phase, the Government sanctioned Phase 2 project in 2006 toward hosting of Commonwealth Games in October 2010.

    Services Provided As the lead consultant of the consortium appointed by DMRC, OC Global provided the following services:

    Enhance the detailed project reports Review tender documents and assist

    in tender evaluation Review all design works Manage contracts of all packages Supervise and monitor the works of all

    contractors, design consultants, system suppliers and manufactures

    Ensure safety at all worksites Mitigate social & environmental impact Coordinate activities of all contractors Verify testing & commissioning and

    trial operations of entire systems Plan operations and maintenance Provide training and technology

    transfers tothe DMRC personnel

    Actual Project Works The Phase I of the project consisted of construction of 3 corridors of heavy rail urban transport system to accommodate 2.2 million commuter trips per day and result in 2,400 less buses on the roads and a 50% reduction in the pollution level.

    The Phase 2, another six radiating lines (three for extension of the existing lines) from the city center to outer Delhi were constructed. The extended metro network connects the different city areas including the suburbs. Phase I and Phase 2 are fully operational since January 2013.

    Today, land prices surrounding the metro showremarkable growth and developers property investment becomes significant, taking advantage of great accessibility. Delhi Metro is a stunning example of successful development and often called as a symbol of India-Japan partnership.

  • Sofia Metro Extension (Bulgaria)

    Problem Addressed by the Project

    Sofia is the capital of Bulgaria, having a population of about 1.2 million. The city is inconvenienced by narrow roads and rapidly increasing numbers of automobiles. Development of metro systems is regarded as an important policy to enhance city's transportation and maintain the landscape of the thousand-year-old cultural assets located in the central city.

    The first seven stations of the Metro Line No.1 linking the western residential area and part of the downtown area (about 8.1 km) were constructed under cut and cover method by the Sofia's rapid transit company. It was completed in October 2000. Afterwards, JICA provided ODA loan to finance the Sofia Metro Extension Project from the 7th to 9th stations. The project employed the shield tunneling method for the first time in Sofia. The method enabled tunnel construction to proceed with minimal requirement for surface excavation, thus avoiding hindrance to traffic. However, careful attentions were required to avoid underground utilities and buried cultural heritages. Upon completion, the extended system improved the financial and institutional capabilities of the metro operator and contributed the enhancement of transportation network, while safeguarding rich cultural assets.

    Services Provided

    Reviewed, revalidated and supplemented the preliminary designs Reviewed, enhanced and finalized tender designs / documents for the

    entire civil and E&M packages for metro extension works Assisted the selection of contractors, suppliers and project consortium Supervised and monitored construction works and E&M works Supervised and monitored testing & commissioning and trial running Prepared manuals of operation and maintenance of the signaling and

    communications systems.

    Actual Project Works

    Total length of the project is 2.3 km with twin single-track tunnels. The work includes construction of two stations by cut and cover method. The west end of the project was connected to the existing Station-7 making no adverse impact to the day-to-day operations, while the east end of the project was connected to an existing tunnel which was constructed about 20 years ago. Project works include: tunneling, stations, trackwork, power supply & distribution system, signaling & communication system, and commissioning.

  • Railway Modernization Project (Romania)

    Problem Addressed by the Project

    The European Union (EU) has planned to open Europe-Caucasus-Central Asia (TRACERA) transport corridors by railway and road. These corridors cross the Black Sea and the Caspian Sea from east to west and connect with important Pan-European Transport Corridors. Corridor IV with a total length of 3,285 km crosses the countries of Germany, Austria, Czech Republic, Slovakia, Hungary, Romania, Bulgaria, Greece and Turkey.

    On Romanian territory, Corridor IV has a railway component with a total length of 841 km across the north and to the east on a route through Curtici-Arad-Sibiu-Brasov-Constanta. This railway route is the most important of the
