SCOPE OF WORK:
Meghna Bridge, situated on a 25 km stretch of Dhaka-Chittagong Highway (NH1) is a pre-stressed concrete bridge with central hinges that opened for traffic in 1991. Abnormal vibration and sound were noticed in Meghna Bridge during the passage of heavy vehicles over it. Investigation revealed that the central hinge bearings and expansion joint of Meghna Bridge were damaged. We accepted the project for rehabilitation.
DESCRIPTION OF WORK:
The rehabilitation work of the 930 meter-long Meghna Bridge & 1410 meter long Gumti Bridge involved the temporary solution of 96 fully damaged hinge bearing.
The Challenges
It was the first ever expansion joint & hinge bearing repair job of a bridge in Bangladesh. Naturally, it was an immense challenge for us considering that we were the first in Bangladesh to perform it.
