First phase of proposed 55.3 km 3-line network involves 11 km of underground railway between Delhi University and the Central Secretariat near Parliament House using TBMs. Completion 2007. General consultants: joint venture led by Pacific Consultants International (Japan) and including Jarts and Rites. Client: Delhi Metro Rail Corporation. September 1998.   Fifteen consortia, each associated with one or more local companies, have been shortlisted for construction of the 11 km-long underground section. The rest of the network will consist of 44.3 km of elevated and surface lines from Shadara to Nangloi and Subzimandi to Holambikalan. The US$690 million underground contract will be let as two separate packages: design and construction of the 4 km-long section from Delhi University station to the south end of the Inter-State Bus Terminal (ISBT); and design and construction of the 7 km-long section from ISBT to Central Secretariat. Among the shortlisted bidders for one or both packages are: Impregilo (Italy), Nesco (Spain), with Gammon (India); Kumagai Gumi (Japan), Skanska (Sweden), with Hindustan Construction (India) and Itochu (Japan); Dyckerhoff & Widmann (Germany), Shimizu (Japan), and Larsen & Toubro (India); Samsung (South Korea), with Ircon International (India); and Hyundai (South Korea), with Jai Prakash (India). Total cost of the metro project is now expected to be more than US$1.8 billion on completion. January 2000. Line 1 will run 11 km underground from Delhi University at Vishwavidyalaya in the north to Central Secretariat in the south, serving 10 stations. Line 2, the first 25 km surface/elevated route, will link Shahdara in the east to Nangloi in the west via Subzimandi and Tri Nagar. Line 3 was intended to run 19.3 km from Subzimandi to Holambi Kalan, but as this parallels an existing Indian Railways (IR) line, the government is considering whether to build a 16-km route from Tri Nagar to Barwala instead. Tenders are currently being evaluated for construction of Line 1 (underground), and the winning contractors should be announced later this year. Firms shortlisted for the project include Kumagai Gumi, Kajima Corp. and Obayashi of Japan, Skanska AB of Sweden, and Dywidag of Germany. With a water table only 1.5 m below ground level, underground construction will be challenging. From Vishwavidyalaya to New Delhi the ground is a mix of soft soil and quartzitic rock varying from sound to highly weathered. Between New Delhi and Central Secretariat the soft soil is mixed with silt, clay and sand. Construction will be split into two sections, north and south of ISBT. Nine of the stations will be built by cut-and-cover, except Chwari Bazar, which will be NATM. The running tunnels will be bored by EPBs. The northern half of the route, from Vishwavidyalaya to ISBT, is due to open in March, 2004 and the southern section in March, 2005. To help with project management, DMRC has brought in a number of general consultants, including PCI, Tonichi and JARTS of Japan, Parsons Brinckerhoff International of the USA, and RITES (Rail India Technical & Economic Services) of India.
