Dhaka Metro Rail is part of Bangladesh's plan to provide sustainable transport in the rapidly growing capital city, home to over 22 million people. As rural and coastal migrants seek better opportunities, Dhaka has become one of the world's most crowded urban areas. The metro rail network will have six planned lines covering 140 kilometers to reduce traffic congestion and pollution. MRT Line-1, one of these lines, will be Bangladesh's first underground metro railway. RISE Structural Design, Inc. designed the stations along MRT-1. The rail line stretching 31.24 kilometers will connect Hazrat Shahjalal International Airport and Kamalapur Railway Station. It will have two sections: the 19.87-kilometer underground Airport route and the 11.369-kilometer elevated Purbachal Route. Construction of the train line had already started when RISE was tasked with designing these stations. This added constraints to their project - the height of the tracks and platforms was already set. The design team used Bentley software to model and analyze the strength of the steel structures and concrete stresses within those predetermined constraints. This approach helped reduce 10% to 15% of the concrete used to support the beams and helped to reduce the project's overall carbon footprint. When it is finished, MRT-1 is expected to carry 800,000 passengers. #engineering #structuralengineering #railway #infrastructure #transportation #bangladesh #DhakaMetro
