Metro Rail A Reflection of a New Dhaka

Metro Rail will make Dhaka closer to people living in its immediate vicinity. It will change the landscape of the metropolitan city of 20 million people. It will also change the demography in a city where 45,000 people live in per square kilometer area. Motijheel was called the heart of the Dhaka city but thanks to Metro Rail, each station is being developed as a single heart. So, centering the ‘Mass Rapid Transit’ MRT-6 route’s 17 elevated stations, residential and commercial areas are undergoing major changes. Currently, it takes two hours to travel from Uttara to Kamalapur station; the Metro Rail service will bring that down to 40-45 minutes only. During peak hours, the $3 billion Metro Rail will be able to transport around 1800 passengers on each direction in every three and a half minutes on this route, resulting in an average reduction of 15 buses and 100 different types of vehicles on each direction. Traffic congestion is also expected to be reduced and huge working hours will be saved. As per the Minister of Road Transport and Bridges, Mr. Obaidul Quader, five more Metro Rail-routes will be constructed in Dhaka by the year 2030 when the face of Dhaka will change. It will cost about US$ 22 billion. On June 26, 2016, Prime Minister Sheikh Hasina officially inaugurated the construction work of the MRT-6 project. This marked the beginning of the construction work of the Elevated Metro in Dhaka. The elevated Viaduct on which the Trains will run is about 13 meters above the ground. In Dhaka, out of 17 stations on the 21-km-long MRT-6 route, construction of a 12 km railway track from Uttara to Agargaon and construction of 9 stations is nearing completion. Under the construction package CP-3 and CP-4, the stations are Uttara North, Uttara Center, Uttara South, Pallabi, Mirpur-11, Mirpur-10, Kazipara, Shewrapara and Agargaon. The plan to inaugurate the service along this section has been set for December 16, 2022. Each Metro station has a 180 meters long and 25 meters wide Concourse Hall. Passengers will use the stairs, escalators and elevators to purchase/recharge MRT Pass or Rapid Pass from the Concourse Hall and then board the Train from the Platform located above it. Each of these three-storied stations is built on an average 200,000 square feet area. Most of the materials used for constructing these stations have been procured locally. One of which is the use of different types of Tiles. These tiles include floor tiles, wall tiles, glass tiles, tactile tiles (for passengers with special needs), brick claddings for walls, paving blocks for platforms, and stone tiles. And these are special types of vitrified tiles made of high temperature, which do not corrode easily. Only 5 companies in the country are considered eligible to supply these tiles. About 50% cost has been saved due to the use of products manufactured locally. Metro Rail will require about 18 megawatts of electricity to be taken from the national grid. Then it will be converted to DC electricity. For this, eight Traction substations have been installed in Uttara Depot, Uttara North, Uttara South, Mirpur-11, Shewrapara, Bijoy Sarani, Shahbag and Motijheel Stations. The cost of operation and maintenance for Metro Rail is yearly one thousand crore taka will be borne from the fare and other sources such as rental/leasing of commercial and advertisement spaces. The government is thinking about keeping the fare affordable for passengers from all walks of life with subsidies at first. The ministry of Road Transport and Bridges gave an impression that the fare may vary between a minimum of 20 Taka to 100 Taka depending on the length of the journey along the 21-km route. There will be various announcements for passengers in Metrorail in both Bangla and English.   From uttara to kamalapur Metro Rail from Uttara to Kamalapur will take about 45 minutes. Although the highest design speed of the Metro Train is 110 kilometers per hour, the actual speed may vary due to the curves on the route and other operating factors. 17 stations in 21 kilometers mean each of the stations are located within one and a quarter kilometers from another. The Trains may stop for a maximum of one minute at each station. During peak hours, trains will run every three and half minutes apart. An estimated 60,000 passengers will be able to commute on both directions per hour from early morning to midnight. Once fully completed, 24 sets of Metro Trains will run from Uttara to Kamalapur. However, 12 sets out of those will be used for the first phase operation from Uttara to Agargaon. Initially each of these trains will have six coaches with an option of adding two more coaches to each of the Train sets if necessary. Each Train will have a total seating and standing maximum capacity of 2,308 passengers. According to this calculation, at the beginning, it will be possible to transport about half a million passengers per day. One of the six coaches on each train will be reserved for women. However, other coaches of the train will also allow men and women to travel together. MRT Line-6 was initially planned to reach Motijheel, but later it was extended by 1.16 km to reach Kamalapur Railway Station. Though, physical work for the extension of Motijheel to Kamalapur section has not started yet, the preparatory works for this extension is ongoing in full swing. In addition to MRT Line-6, 3 other Metro Rail routes (MRT Line-1, MRT Line-4 & MRT Line-2) will also have stations adjacent to the Kamalapur Railway Station. Once completed Kamalapur Railway Station will transform into a modern transit hub. Even though, initially, the timeframe to complete the MRT Line-6 project up to Motijheel was set for 2024, Bangladesh Government is keen to complete the project ahead of that target. If the current pace of work remains unchanged, hopefully, the people of Dhaka will get the much awaited MRT Line-6 by December 2023. Minister Obaidul Quader said

A stunning display of architectural grandeur, welcoming students

We are all familiar with the Dhaka University and its grandeur. Even now, when major infrastructures shroud the beautiful campus, its thousands of students still enjoy a little retreat among greeneries in, for example, Muktamancha or Suhrawardi Udyan. The same can also be said for all public universities. It’s on one such campus where BUET alum Khandaker Ashifuzzaman Rajon, Principal Architect of Cubeinside Design Limited, studied architecture. Of course, Rajon’s idea of a campus vastly differs from that of private university students. Thus, when tasked with designing a campus for Southeast University (SEU) well within the hustle-bustle of Dhaka, Rajon had to tumble down all his cards and think of fresh ways to give the students of Southeast University some taste of his own campus-going experience. The project being the permanent campus came with the additional worry of how to design the structure that would inspire students to enrol just looking at the place years, even decades, after its novelty factor has worn off. But before we go further into Rajon’s and the Southeast University permanent campus story, allow us to tell you what it is about all private universities competing to move to their permanent campuses. Competition here is particularly good, as all private universities want a permanent campus that is the most student-friendly while being attractive. UGC, the University Grants Commission, recently stipulated that all private universities, without fail and exception, move to a permanent campus that facilitates students with open space, interactive classrooms, and all the amenities that university students abroad enjoy from a campus. So, that triggered the mass relocation of private universities to actual campuses in place of stuffy buildings. Rajon opened his story with the mandatory 50% open space policy in the rulebook for building a new permanent campus. “The idea of a cubic volume in the centre of the campus came from this rule. I wanted the rest of the structure to look over the open space as the centerpiece of the campus. As a by-product, a central courtyard would help dissipate light and aerate its surroundings, like the classrooms, for example. However, the Board wasn’t initially unanimous about the central open space idea, but it was up on completion that they saw my vision behind this design choice, and this later became everyone’s favorite part of the entire campus,” began the architect. But beyond the Board’s stamp of approval, the campus just had to be completed and made fully functional within a very limited window of time, set by the UGC. If you happen to be a current student of SEU or have even visited the place, you may have taken a moment’s pause and thought of how it was even possible to erect an edifice as such in such a constricted amount of time. This is where the seasoned, but young, architect’s ingenuity just begins. If my memory serves well, I remember seeing in the popular cartoon show “Popeye: The Sailor Man” Popeye stacking floors upon floors of a skyscraper with steel I-beams, all in one shift, of course with the help of his special formula spinach, but steel I-beams were the actual hero that allowed for construction at such mind-boggling speeds. I am not inferring that Rajon got his hands on Popeye’s spinach, but being the well-bred architect that he is, he knew that I-beams would be an ideal instrument in his race against time. He explained how: “All the brick and concrete facades of the entire complex give it the impression of an RCC (reinforced cement concrete) structure, but its basic skeleton is made of I-beams. This bought me time! I-beams, like Lego, just have to be joined together using nuts and bolts without trading modern looks for time or structural integrity, but we did trade off some extra money to be able to complete construction in time.” The mission he had in mind to let light dance around the entire complex with the help of a central open space was a massive success. As the structure was shaping up rather quickly, it was instantly visible that the same campus took on different faces because of the changing sunlight that entered at different angles at different hours of the day. As a creator, the play of light and shadow had Rajon all emotional when he laid eyes upon the outcome. “The place would change its look at the change of each season too,” he said. “A few of my acquaintances who study at SEU find the campus quite photogenic. As climates change, they post photos and reels of different parts of the campus on their social media, and from there, I get to observe, from an onlooker’s perspective, how the most important beneficiaries of the campus—who are the students—are lovingly accepting it and are also low-key boasting it on their socials.” All this is to say that a structure made exclusively out of complex mathematics and engineering can also evoke emotions when made with the human angle in the mix. Ever since the permanent campus opened its doors to students in early 2023, the entire place teems with students in any direction imaginable. Not only is that the proper utilisation of space, but it also points towards the inevitable fact that students love their new campus. Everyone is doing what a student does: going in and out of class, singing, laughing, teasing, playing with classmates between classes, and most importantly, enjoying their newfound freedom in such a capacious facility that can house over 12,000 students at once! The former campus building is in the backyard of the new campus. It will be demolished soon and replaced by a new building to house the School of Engineering. It is to be designed by Cubeinside Design Limited as well. “But looking at the design of the new building and the one we just completed, no one will be able to say that the same architecture firm was behind the drawing board of the second one; it’s that different from the

Kamalapur Railway Station: A Gateway to Journeys in Bangladesh

Kamalapur Railway Station, officially known as Dhaka Central Railway Station, stands as a bustling gateway to the vibrant capital city of Dhaka. Nestled in the heart of the city, this vital transportation hub connects travellers to all major cities in Bangladesh. As the largest and busiest railway station in the country, Kamalapur serves as a crucial link, facilitating journeys both near and far. Its rich history, architectural significance, and constant activity make it an iconic landmark. With a unique design and historical roots, Kamalapur Railway Station weaves together the fabric of Bangladesh’s rail network. The station’s significance has increased following the opening of the Padma Bridge. Kamalapur Railway Station (KRS), steeped in history, stands as Dhaka’s historic gateway. Its iron-clad colonial-era architecture evokes memories of a bygone era, a bridge between past and present. But Kamalapur is more than just a transit point; it embodies the spirit of a nation on the move—a pulsating heartbeat that reverberates across Bangladesh. Kamalapur Railway Station stands as a vital link in Bangladesh’s transportation network, connecting people, cultures, and commerce. As trains arrive and depart, the passengers weave intricate stories etched into the very walls of this magnificent station. Here, hope mingles with anticipation, dreams find their rhythm, and reunions unfold. The station’s bustling platforms witness resilience—the quiet strength of travellers forging ahead despite life’s twists and turns. And within its echoing halls, new beginnings take root, fueled by the promise of distant horizons. Kamalapur Railway Station, standing tall against the passage of time, is a living testament to Bangladesh’s architectural ingenuity. It’s not merely a physical structure; it’s a gateway to aspirations, connections, and the beating heart of a nation. As passengers step onto its platforms, they become part of a grand narrative—a journey that transcends mere destinations and becomes an enduring legacy of rail travel in Bangladesh. Architectural Marvel Kamalapur Railway Station stands as a captivating blend of modernity and tradition. More than a mere transportation hub, it represents an architectural marvel that seamlessly connects the past with the present. Designed by the renowned American architects Daniel Dunham and Robert Boughey (Bob Buie) of Louis Berger and Consulting Engineers Ltd. in the 1960s, Kamalapur Railway Station serves as a symbolic gateway to Dhaka. Daniel Dunham, a young architect fresh from completing his studies at Harvard’s Graduate School of Design (GSD), took charge of Berger’s fledgling Dhaka office. His task was to tackle an extensive backlog of new projects. The station’s architecture draws inspiration from both modernist principles and traditional neo-Islamic influences, as well as Bengali styles. It stands as a testament to Dhaka’s modern architectural spirit. Architect Daniel Dunham skillfully blended modernist elements with traditional Bangladeshi architecture. The station’s most striking feature is its parabolic shell roof—a true engineering masterpiece. Stretching over the platforms, this roof provides shelter to passengers. The lattice-like concrete structure fosters openness and allows natural light to filter through, creating a welcoming ambiance.   Kamalapur Railway Station officially opened on May 1, 1968, during President Ayub Khan’s tenure. Its construction cost at the time was Taka 5 crores 30 lakh. When the value of one vori of gold stood at only 100 takas, A year after its inauguration, the Provincial Office of the Railway Postal Service found its new home within this remarkable station building. Design Features The station building is well-suited for tropical climates, providing protection from rainwater like an umbrella. It incorporates various functional spaces, including ticket booths, administrative offices, passenger lounges, waiting areas, and restrooms, all under an integrated canopy-based roof. The structure comprises 36 square domes supported by a total of 49 columns. Above these columns stands a roof featuring 36 slender concrete umbrella-type domes. Each column extends 59 feet high, branching out to support the roof. The open-air design capitalises on Dhaka’s cross breezes while safeguarding interior spaces from monsoon rains. The Kamlapur Railway Station’s thin concrete shell dome-umbrella design, completed by the consultants, has become a local icon, cherished by prominent architects as a cultural heritage piece. The parasol roof continues to define the station’s unique skyline. Architect Dunham immersed himself in Bangladeshi culture, learning Bengali and adapting to local craftsmanship and construction practices. Instead of designing an enclosed monolithic structure with mechanical heating and cooling systems, Dunham leveraged Dhaka’s tropical climate. His innovative roof system provides shade over the station’s offices and facilities, supported by a versatile field of columns. The construction technique involves thin concrete shells, which Dunham explored during his thesis at the GSD. After Dunham’s departure, architect Robert Boughey took over the post, designing tessellating concrete shells for the roof, reminiscent of pointed arches seen in Islamic architecture. These shells were cast on-site using reusable materials. Kamalapur Railway Station, with its remarkable parabolic shell roof, stands as an engineering marvel. This expansive structure spans the platforms, providing shelter to passengers. The station’s circular layout, boasting a diameter of 186 metres, centres around a soaring dome that reaches a height of 26 meters. Eight radial wings extend from the central hub, housing platforms, and tracks. The station’s architecture seamlessly blends modernist elements with traditional Bangladeshi motifs, reflecting the nation’s spirit. The concrete lattice structure allows natural light to filter through, creating an airy and open ambiance. High ceilings and spacious interiors enhance the feeling of grandeur. Kamalapur’s design prioritises functionality while maintaining aesthetic appeal. Geometric patterns, arches, and intricate details evoke the essence of Bengali culture. As a testament to Bangladesh’s identity and heritage, Kamalapur Railway Station stands proudly. The station is an engineering marvel that spans the platforms, providing shelter to passengers. Additionally, in other parts of the country, the Sylhet Railway Station in the north-eastern region and the Chilahati International Rail Station in the north-western part also feature a similar umbrella-like structure. These stations use national flower-shaped “shapla” shells supported by a forest of columns to cover their facilities. Historical Context Bangladesh Railway has been operating in the British period since 1862 in the eastern and western parts of the country, divided by the great river
