Construction of Bus Rapid Transit (BRT) under Greater Dhaka Sustainable Urban Transport Project Package-2 (Gazipur-Airport BRT Corridor):

Consultancy Services for Environmental Monitoring Services by Expert Input (Environmental Specialist) and Quality Test for

(i) Package 1: BRT-2 Gazipur-Airport Corridor including six (06) flyovers.

(ii) Package 2: Construction of Elevated BRT Section (including Tongi Bridge & BRT Stations.

(iii) Package 3: Construction of Pavement, Drain, Pedestrian Facilities and Local Market on Both Sides of BRT; and

(iv) Package 4: Construction of Bus Rapid Transit (BRT) Bus Depot at Gazipur

In order to improve the road based public transport system, the proposed Bus Rapid Transit (BRT) project will restructure the main urban transport corridor from Dhaka’s International Airport to Gazipur through a dedicated BRT route. The BRT project components are: 20km dedicated BRT Main Corridor, including flyover, stations, local roads, drainage & associated structures; two mixed-traffic lanes and one non-motorized traffic (NMT) lane per direction and sidewalks; improvement of 141 access feeder roads in favor of NMT; an efficient high-capacity drainage system all along the BRT corridor; 4.5km Elevated Section between Abdullahpur and Tongi; and a BRT terminal and bus depot in Gazipur.

The BRT project is funded by the Asian Development Bank (ADB) and jointly implemented by the Roads and Highways Department (RHD), Bangladesh Bridge Authority (BBA) and Local Government Engineering Department (LGED). The BRT Main Corridor Component includes Gazipur to Airport Main Corridor Route, including flyover and BRT stations; and Roads and Highways Department (RHD) is the Implementing Agency of the proposed BRT Main Corridor project.
