ISLAMABAD - The Capital Development Authority (CDA) is all set to kick off construction work on Zero Point Interchange (ZPI), but waits for the Prime Minister to formally inaugurate the project. A source in the civic body informed that the Authority had completed paper work and finalized design of the Rs 2.35 billion interchange project and the Karachi-based contractor of the project, Maqbool Associates, had mobilized construction machinery and vehicles to the site. He said that the contractor was all ready to start construction work on the project but he said CDA was waiting for the Prime Minister to formerly inaugurate the interchange project at the gateway to the federal capital. In this regard, a request has been forwarded to the Prime Minister on Tuesday, he maintained. It is now up to the PM as to what date he chooses to inaugurate the project, he further said. The project, which remained in doldrums for the last two decades for one or the other reason, consist of three loops and five link roads, which would cater to the traffic needs of the capital city for the next 50 years. The project would take 2 years for completion, said Mumtaz Hussain, Project Director, ZPI, however, he said, they would try their level best to conclude the construction work in 21 months. It is pertinent to mention here that ZPI initially consisted of four loops, but the fourth loop was removed due to the unavailability of sufficient space. However, a senior official of the Authority said that the fourth loop, one on the side of Pakistan Monument, required to be built in shape of a tunnel, because of which CDA should had to bear huge cost of maintenance. The loop was, therefore, skipped, as the project would have to generate nothing in future, the official maintained.    Mumtaz said that the civic agency had already allocated Rs 700 million for the project during the year 2008-09. However, additional amounts would be allocated for the project during the same financial year as the Authority, he said, intended to carry out the project in shortest possible time. He informed that special utility corridors would be built along the various roads of the interchange so that these may not be shattered in future for laying down gas or water pipelines. Moreover, a fine finish would be given to the interchange for which additional amounts would be kept aside, he said.Zakaullah Khan, Project Manager ZPI said that Maqbool Associates had carried out a number of mega road construction projects, including bridges and interchanges, in Karachi and Hyderabad.  However, he said, they would do their best to win the trust of CDA and residents of Islamabad, too. He said they had completely mobilized machinery to the site and waited only for a go-ahead signal from the Authority.
