Construction work on the eagerly anticipated metro rail system has been in full swing with the erection of a viaduct on two piers at Diabari in Uttara in the first week of April. A viaduct will also be erected soon on two piers currently under construction in Agargaon.
A viaduct is a long bridge-like structure, typically a series of arches, carrying a road or railway across a valley or other low ground. A pier is a solid support designed to sustain vertical pressure, in particular the pillar of an arch or supporting a bridge. "The metro rail system will be clearly 'visible' in June," said Managing Director of Dhaka Mass Rapid Transit Company MAN Siddique, reports bdnews.
According to the latest report from the Dhaka Mass Rapid Transit Development Project, as many as 15 percent of the project work has been completed as of March 31. However, progress on the project has sped up over the past 15 days, claimed Siddique. "Work is proceeding at full speed. You will see, all the piers will be constructed by June," he told bdnews24.com on Sunday.
"We'll set up the viaduct on the two piers in Agargaon and this way, the next piers will be constructed one after another."The former secretary expressed the hope that the metro rail from Uttara, the starting point of the metro rail project, to Agargaon will be inaugurated by December 2019.
The project is scheduled to be complete by 2024. "But we are making efforts to complete the work beforehand in line with the prime minister's instructions," said the managing director."We have taken special efforts and changed the course of our action plan, which we are now following. We hope to inaugurate metro rail from Uttara to Agargaon by December 2019 and to Matijheel by December 2020 if work continues at the present pace," he said. Motijheel is the ending point of the system.
The 'pre-cast segment box' of viaduct has been set up on pier no. 22 and 23 and could be seen on Sunday. However, those were not connected and supports at the bottom have not been removed.Project officials said the supports at the bottom will be removed once the segments are connected.
The entire construction area has been surrounded by concrete walls with workers buzzing inside. On-going piling work is seen at different points up to Agargaon. Workers are at work constructing one pier in front of Sher-E-Bangla Agriculture University in Agargaon.
Project officials said the project is being implemented under eight packages. Among those, land development for the depot began in Diabari under package no.1 in Oct 2016 which has been 100 percent completed.Public works in the depot area is being done under package-2 which began in October 2017 and progressed 4 percent. Constructing stations and viaduct from Uttara to Agargaon under package-3 and 4 has progressed 5 percent.
Constructing stations and viaduct from Agargaon to Matijheel under package 5 and 6 have not been started but the land survey has been done.The electrical and mechanical system of the project is being implemented under package 7. The evaluation report of financial proposal for this package has been sent to JICA for approval.
Rail coach and depot equipment collection is being done under package 8, which has progressed at least 9 percent, sources said.All 12 survey works from Uttara to Motijheel have been completed at different phases. Utility of the project has been relocated from Uttara to BIRDEM hospital in Shahbag.
Enclosing work on the project area has been finished and road medians up to Agargaon have been removed.Works for all nine test piles to Agargaon have been completed. As many as 363 out of 383 check borings to test soil quality have also been completed. The remaining 20 check borings will be done by next week, said MD Siddique.
"At present, 704 out of 2,378 piles have been constructed. Pier caps will be set up on top of piles and 731 piers will be set up on pier caps. Viaducts will be erected on piers, on which the metro rail will run," he explained."We have set the pier caps in Agargaon and it will take 10-15 days maximum to set the piers," he said, adding they have already ordered for the coaches."We have sent an order to Japan for the train. They are manufacturing our trains in red and green colours."
