The officials admitted that the construction work is progressing a little slower due to some other reasons including this but the project schedule would not be effected for this.

"The maps of different service providers are faulty and could not always locate the exact position of the infrastructure they have that's why we have to find out their position to work," said Ashiqur Rahman, project director (PD) Gulistan-Jatrabari flyover.

He also pointed out that the underground construction naturally takes little more time.

"Rainy season is another reason for slow progress. We hope to get full speed after the underground work is done," said Rahman.

The government has formed a committee involving representatives from all utility service providers who have infrastructure in the flyover construction site to help the constructing authority and save their own infrastructure thereby.

The utility service providers, however, denied that their maps are unable to point the exact location of the infrastructure.

"Our maps show position of all the infrastructures precisely and there should be no such problem with our Wasa pipes," said Nurul Haque, chief engineer, Wasa.

He also said that if there is any problem in identifying the position of any infrastructure of any service providers they could take help of detectors.

"Wasa pipes, in spite of lacking an electromagnetic field, could be detected properly with the detector. Infrastructure of other service providers could be detected more easily as these have electromagnetic field," said Haque.

Experts said that it was too early to predict either the project would be delayed due to this problem or not. The project started in June this year and is officially scheduled to be completed by June 2009.

After a long process of examination regarding relocating and reinstalling utility services the construction and utility service providers decided to construct the flyover without moving the existing infrastructures.

They are now putting the pillars of the flyover at the spots where there is no underground installation.

A feasibility study committee with the Bangladesh University of Engineering and technology (Buet) Vice chancellor Prof Dr Mohammad Ali Mortuza as convenor said in his report that it was possible to construct the flyover keeping the utility service infrastructures intact and that would save at least Tk150 crore.

Infrastructure of Dhaka Water and Sewerage Authority (Wasa), Dhaka Electricity Supply (Desa), Titas Gas, Bangladesh Telegraph and Telephone Board (BTTB) and few other service providers has been resolved in February, as the flyover authorities have decided to construct the flyover without moving the existing infrastructures.

Besides, the construction of the Gulistan-Jatrabari flyover that is now going on at the Sayedabad Janapad Road site has worsened the traffic problem in the area. Residents and commuters welcomed the construction but urged to keep to congestion at a tolerable limit.

It was observed that only one bus could pass trough the narrow road on both sides that are left for the traffic after a boundary wall was built around the construction site.

"It takes at least 2 to 3 hours to cross the Janapad Road intersection and if we have to continue with this situation for the next three years we will go nuts," said Azad, a resident of Demra.

For the lack of a diversion road, construction areas in Shanir Akhra, Dania, Demra, Jatrabari, Shyampur, Sayedabad, Jurain, Postagola and all other roads in the vicinity, are facing acute traffic congestion.

"If the government finds an alternative like widening the road as they did during the construction of the Mohakhali flyover we will get little rid of this problem," said Golam Murtoza, a resident of Sayedabad.

The project director of the flyover requested the residents to cooperate and promised they would try to reduce the sufferings of the commuters at their level best.

The construction of the 7.5 kilo meter long flyover, the longest of its genre in the country will cost Tk 706 crores. It will have 13 ramps and six entrances with four lanes on either side.

Belhasa-Acom, the investing and implementing authority will complete the project on Built Own Operate and Transfer (BOOT) basis. The constructor of the flyover will own and operate the flyover for 24 years and afterwards will handover the ownership to the Dhaka City Corporation (DCC).

Unlike other flyovers in the city, commuters will have to pay a toll to ply through the flyover.
