Dhaka MRT Line 6

Dhaka Metro Rail is a mass rapid transit system under construction in Dhaka, the capital and the busiest city of Bangladesh.

MRT Line 6 consists of 16 elevated stations that are each 180 meters long and 20.1 kilometers of electricity-powered light rail tracks. Except for the depot and some of the LRT (Light Rapid Transit) that would run beside it, Line 6 will be elevated over current roadways, largely above road medians, to let traffic to flow beneath it, with stations likewise elevated.

Dextra supplied various solutions to the project.

50,000 linear meters of Sonitec, an easy-to-assemble and time-saving tube solution used for the CSL (crosshole sonic logging) testing of foundation piles.

1,000 sets of Shear Key system, a post tensioning bar system that acts as a permanent seismic restrainer for the connection of elevated metro precast segments.

More than 50,000 pieces of Bartec coupler were also applied for the reinforcement of the station structures.

Construction of Line 6 is anticipated to be completed in 2022.
