Phase-I of the project, which had an initial investment outlay of over Rs 14,600 crore, has seen an increase in investment up to Rs 19,000 crore, owing to various issues including the issues in contract, price escalations and variations in the project after the conception.
The phase is expected to be completed by December next year, said a senior compant official requesting anonymity.
It is also tweaking the model it has implemented in Phase I, under which the responsibility of both design and building vested with the contractor, making their job riskier. It may be noted that the works, awarded to a joint venture between Gammon India and Russian contractor Mosmetrostroy, for design and build of a stretch of underground operations, were delayed after the Russian partner allegedly abandoned the project abruptly.
The official said that the Union Urban Development Ministry is in consultation with various metro rail companies in the country to bring in a solution to such delays in the projects. The ministry is looking at bringing in standards on sourcing of trains, telecom, signal and construction system materials for the metro rail projects.
The company has decided to take the onus of designing, which would bring matters under its control, and reduce the risk of the contractor.
The Japan International Cooperation Agency (JICA) officials are expected to visit the City next month to discuss with the government on the extension project. Out of the Rs 3,700 crore proposed investment for the project, around Rs 2,100 crore is expected to come from JICA.
