From an 1876 colonial survey school at Nalgola to Bangladesh's top engineering university — BUET's history, research role and the Abrar Fahad reckoning.
The Bangladesh University of Engineering and Technology — BUET to everyone in the country — is the summit of technical education in Bangladesh. Its compact campus at Palashi, in the middle of Dhaka, holds the country's oldest engineering institution, its most fiercely contested admission test and a disproportionate share of the engineers who design Bangladesh's bridges, power stations, flood defences and buildings. The university's own history runs through almost every era of the region's past: it began in 1876 as a colonial survey school in Old Dhaka, was carried upward by a Dhaka nawab's endowment, became a degree college in the first months of Pakistan, and emerged in 1962 as a full university. To follow that road is to watch technical education in Bengal grow up — and to see how an institution built to serve an empire became one of the foundations of a new nation.

The Dacca Survey School — usually rendered today as the Dhaka Survey School — was established in 1876 at Nalgola, in Old Dhaka, on a site west of what is now the Sir Salimullah Medical College campus. Its founder was the Government of Bengal, and its purpose was narrowly practical: British India needed trained surveyors to measure land, settle revenue records and lay out the roads, railways and irrigation works of the province, and it needed them locally rather than imported.
The school's course lasted two years and prepared students for the Sub-Overseer's examination, which certified land surveyors for government service. It was, in other words, a trade school for the measurement of Bengal — not yet an engineering college in any modern sense. But the demand behind it kept growing. As public works multiplied, so did the need for overseers and sub-engineers with more than surveying in their training. A Bengal public-instruction report counted 117 students at the school on 31 March 1903, a respectable size for a single-purpose institution, and the pressure to widen its teaching beyond surveying had become impossible to ignore. What the school lacked was money — and that arrived from the city's own first family.
The Dhaka Nawab family were the great patrons of education in the city, and Khwaja Ahsanullah, the nawab who died in 1901, had endowed donations for the survey school's development. In 1902 his son and successor, Nawab Salimullah, released a grant of 112,000 rupees in fulfilment of his late father's wish. It was the decisive gift in the institution's history, and the gratitude was made permanent: in 1908 the school was renamed the Ahsanullah School of Engineering.
The renaming came with a genuine change of level. From 1908 the school offered three-year diploma courses in civil, electrical and mechanical engineering — the classic trio of the industrial age — alongside its surveying work. In 1912 it moved across the city to new premises at Palashi, the site the university occupies to this day. For the next three and a half decades the Ahsanullah School of Engineering was the principal diploma-level engineering school of eastern Bengal, turning out the sub-engineers and overseers who staffed the province's public works, railways and municipalities. Its standing in the city was such that in 1938 the Prime Minister of Bengal, A. K. Fazlul Huq, personally appointed its principal, Hakim Ali — the man who would lead the school through its transformation into a college.
Partition changed everything. When British India divided in August 1947, East Bengal became the eastern wing of Pakistan and suddenly needed degree-level engineers of its own. The Chief Minister of East Bengal, Khawaja Nazimuddin, approved the school's upgrade, and it became the Ahsanullah Engineering College — the Faculty of Engineering of the University of Dhaka. The college was formally recognised by the government of East Bengal in 1948, with Hakim Ali as its first principal, and began four-year bachelor's courses in civil, electrical, mechanical, chemical and metallurgical engineering.
Among the first generation of degree students was a young man whose career would carry the college's name around the world. Fazlur Rahman Khan had begun his civil engineering studies at Bengal Engineering College in Shibpur, across the new border in India, but Partition forced him to leave in his final year. He completed his Bachelor of Civil Engineering at Ahsanullah Engineering College in 1950, worked briefly as an assistant engineer and a teacher, and in 1952 left for the University of Illinois on a Fulbright Scholarship — the first step toward the tubular designs that would reinvent the skyscraper.
The college matured quickly. M. A. Rashid, its principal from 1954 and the first Bengali to hold the post, pushed it toward research; a new curriculum and the semester system arrived in 1956. The next step was legal: the Engineering and Technological University Ordinance of 1961 cleared the way, and on 1 June 1962 the college was raised to a university — the East Pakistan University of Engineering and Technology, or EPUET — becoming the fourth university in East Pakistan. Rashid became its first vice-chancellor. A partnership with the Agricultural and Mechanical College of Texas brought American professors to Dhaka to teach and help shape the curriculum, and postgraduate study and research, the stated reasons for the upgrade, took root.
The university was barely nine years old when the Liberation War came in 1971. After independence, EPUET took the name it still carries: the Bangladesh University of Engineering and Technology. Its first convocation in its new identity was held in 1973, and the decades that followed were ones of steady multiplication — new departments as new fields opened, from computer science and engineering to biomedical engineering; new institutes for specialised research; and a growing postgraduate school alongside the undergraduate one.
The physical heart of the place remained the Palashi campus, about ninety acres of academic buildings, workshops and halls of residence in the centre of the capital. Student life centred on the nine halls, most of them named for figures of national history: Ahsanullah Hall for the nawab whose gift remade the school, Sher-e-Bangla Hall for Fazlul Huq, halls for Titumir, for Suhrawardy, for the university's first vice-chancellor M. A. Rashid, and for the national poet, Kazi Nazrul Islam. Hall life — its adda, its dining rooms, its fierce loyalties — became as much a part of a BUET education as the laboratories. It would also, in time, become the setting of the university's darkest chapter.
A small university in a delta country cannot afford research as ornament; BUET's research grew around the problems outside its gates. The channel for much of it is the Bureau of Research, Testing and Consultation (BRTC), the body through which the university's teachers and laboratories take on testing and consultancy for government agencies and private clients — checking materials, advising on designs, and lending the institution's authority to projects across the country. The Department of Water Resources Engineering's consultancy record, run through BRTC, runs from groundwater studies to advisory work for the national Flood Action Plan drawn up for the Ministry of Water Resources.
Water, inevitably, has its own institute. What began in 1974 as the Institute of Flood Control and Drainage Research was renamed the Institute of Water and Flood Management (IWFM) in 2002, and it remains the country's leading centre for research and postgraduate teaching on floods — the defining natural fact of Bangladesh. Disaster research has a second home in BUET-JIDPUS, the BUET-Japan Institute of Disaster Prevention and Urban Safety, one of eight institutes that now sit alongside the departments, covering fields from appropriate technology and ICT to accident research, nuclear power engineering and robotics. The university's applied work has repeatedly crossed into national life: its Institute of Information and Communication Technology designed Bangladesh's first prepaid electricity meters for the Dhaka utility in 2004, and research is sponsored by a long list of outside bodies — UN agencies, the World Bank, the Asian Development Bank, the European Union and the University Grants Commission among them. A central hub, the Research and Innovation Centre for Science and Engineering (RISE), now coordinates that effort.
For decades, the halls that gave BUET its warmth were also governed by the ruling party's student wing of the day, and the control was enforced with violence. The warning signs were old: in 2002 a first-year chemical engineering student, Sabekun Nahar Sony, was killed in crossfire when two factions of the Jatiyatabadi Chhatra Dal fought a gun battle on campus. A women's hall now carries her name.
The reckoning came on the night of 6–7 October 2019. Abrar Fahad, a second-year student of electrical and electronic engineering, was taken to Room 2011 of Sher-e-Bangla Hall and beaten to death over several hours by activists of the Bangladesh Chhatra League, the student wing of the then ruling Awami League. His offence had been a Facebook post criticising Bangladesh's agreements with India. Bangladesh erupted. BUET students protested for nearly two months, and the university expelled 25 students for life over the killing, while the vice-chancellor banned all organisational student politics on campus. The criminal case moved faster than most: on 8 December 2021 a Dhaka tribunal sentenced 20 of the accused to death and five to life imprisonment, sentences the High Court upheld in full on 16 March 2025; the convicts' appeal is still pending before the Appellate Division. The full story of Abrar's life, murder and legacy is told in his Wiki Bangla profile.
The ban on campus politics has held, and students have repeatedly voted to keep it: an internal poll in April 2024 recorded about 97 per cent of respondents against organisational politics at BUET, and the Chhatra League itself was banned nationally later that year. Memory has been institutionalised too. In February 2025 the central library was renamed the Shaheed Abrar Fahad Library, and that October a memorial plaque was installed at Sher-e-Bangla Hall, the building where he died.
Today's BUET teaches through 18 departments under six faculties — Chemical and Materials Engineering; Civil Engineering; Electrical and Electronic Engineering; Science; Mechanical Engineering; and Architecture and Planning — with undergraduate programmes in 13 departments and master's and doctoral work across nearly all of them. The latest datable official figures, published by the University Grants Commission in 2020, recorded 9,234 students, among them 3,598 postgraduates, taught by 579 academic staff; the university's budget for 2024–25 stood at Tk 229.30 crore. In the QS World University Rankings 2027 it sits in the 711–720 band, the highest-placed engineering institution in the country.
Entry remains the real distinction. BUET admits about 1,309 undergraduates a year, and the funnel above those seats is among the narrowest in Bangladeshi education. For the 2024–25 session roughly 26,000 students applied; 24,211 were allowed into a preliminary screening test, and 7,552 reached the written examination. The following year the preliminary test was dropped and the top HSC science candidates shortlisted directly — 9,051 candidates sat the written test in January 2026 for the same 1,309 places. A BUET seat is thus a national event, announced in newspapers and celebrated in home towns, and its graduates go on to staff the ministries, utilities, design firms and universities that build and run Bangladesh — while, like Fazlur Rahman Khan before them, a steady stream carry the Palashi training to the top of world engineering.
Few universities carry their country's whole modern history in one campus. BUET began as a school for measuring other people's land, was lifted by a nawab's gift into an engineering school, and was remade by Partition, by 1962 and by 1971 into the national university of engineering. Its graduates have raised the country's infrastructure and, in Khan, changed the skyline of the world; its failures — above all the hall violence that killed Abrar Fahad — forced a national reckoning from which the institution is still emerging. A hundred and fifty years after Nalgola, the survey school's descendant remains what it set out to be on a far larger stage: the place Bangladesh trains the people who build Bangladesh.

Born in 1921 as compensation for a lost province, the University of Dhaka — the 'Oxford of the East' — shaped a language movement and midwifed a nation.
Jahangirnagar University was established as a project in 1970 and became a full-fledged university in 1973. The university has many programs and initiatives to support this goal, including community service projects, internship programs, and partnerships with organizations in the public and private sectors.
