Water Board has fixed July 20 as the deadline for completing the underground sewerage tunnelling work near Basheerbagh. The total clearing of the site including conversion of open drive pit into closed inspection manhole should be over by July 30, said Board’s managing director, Adhar Sinha.
Mr. Sinha who submitted the inspection report of the three member technical committee on the ongoing work on Saturday to principal secretary, MA&UD, Sam Bob, wanted removal of all the redundant equipment and material from the site including the slurry unit located just adjacent to the flyover in 3 to 4 days.
After detailed site inspection, the technical committee observed that since the work was already completed along the flyover stretch, the machinery and equipment erected in the main road junction may be shifted from the site to ease the traffic flow at Basheerbagh flyover junction and convert the open drive pit into a closed inspection manhole.
The technical committee concluded that the balance length of 12 meter near the ramp portion of flyover can be completed with due precautions for removal of the boring machine from the receiving pit and to demobilize the machinery and equipment away from the site.
The there member Committee comprising ENCs of Water Board, GHMC and chief engineer, HMDA made a joint inspection of the worksite of laying of 1800 mm dia trunk sewer with trenchless technology today.
During the joint inspection it was observed that one drive pit was provided in the midst of Basheerbagh road junction through which the 1800 mm dia RCC pipes are being pushed by jacking through trenchless technology method along the service road of the flyover towards Liberty Junction.
The agency executing the work informed that the pipeline was laid away from the foundations of flyover by observing all the safety measures to the adjacent structures. Further, the agency also informed that they have conducted all the required soil investigation through their consultants.
