Few could have predicted that a humble technician from nearly three decades ago would become the captain steering one of Vietnam’s leading steel structure conglomerates – Dai Dung Group. Under the leadership of entrepreneur Trinh Tien Dung, Dai Dung has risen to prominence, becoming a household name in numerous large-scale projects.
Born in 1969 in Yen Dinh village, Dinh Tan commune, Yen Dinh district (formerly), Thanh Hoa province, Mr. Trinh Tien Dung began his career as a technician in small mechanical workshops in Ho Chi Minh City.
In the early 1990s, Vietnam’s mechanical industry was fragmented, technologically backward, and largely dominated by foreign enterprises. However, driven by the ambition to build a major brand, Trinh Tien Dung decided to start his own business.

Mr. Trinh Tien Dung was born in 1969 in Yen Dinh village, Dinh Tan commune, Yen Dinh district (formerly), Thanh Hoa province.
In 1995, with a small workshop of just 20 workers and a capital of 300 million VND, Dai Dung Mechanical Construction and Trading Company Limited was established. Two years later, he boldly leased land in Le Minh Xuan Industrial Park (Ho Chi Minh City) to invest in a larger factory, serving both external clients and those within the industrial park.
From a newly established company, Dai Dung gradually became a trusted brand for constructing factories for numerous enterprises in industrial zones such as Tan Tao, Song Than, Bien Hoa 2, Tan Thuan Export Processing Zone, Linh Trung Export Processing Zone, and Vietnam-Singapore Industrial Park (VSIP).
By 2000, he expanded by investing in a second factory in Le Minh Xuan Industrial Park to meet increasing order demands. Just two years later, the two factories were consolidated into a third location, marking a turning point for the company’s development in Binh Chanh district. Since then, Dai Dung factories have been established in Long An and Quang Ngai.
From humble beginnings, after 30 years of development, the group now owns 6 factory complexes covering nearly 120 hectares, with an annual capacity of 300,000 tons of steel structures. The workforce has grown to 6,000 employees, including nearly 1,000 engineers.
Beyond production expansion, Dai Dung has diversified into design, construction, and comprehensive supply services for infrastructure, industrial, commercial, and cultural projects. Dai Dung’s products are featured in various domestic and international projects, from industrial zones in Vietnam and factories in Southeast Asia to large-scale projects in the Middle East.
Landmark Projects
One of Dai Dung’s most notable achievements is the Lusail Stadium (Qatar), which hosted the 2022 World Cup final. Within a year, Dai Dung supplied 6,000 tons of steel for Lusail Stadium and a total of 28,000 tons for Ras Abu Aboud Stadium (Stadium 974) – a modular, weldless structure with a technical tolerance of just 2mm.
This success placed Dai Dung on the list of contractors for the Fédération Internationale de Football Association (FIFA) and many leading global construction firms. Unlike many companies that handle only part of the process, Dai Dung manages the entire value chain, from design and production to transportation and installation.
Following this success, Dai Dung was entrusted by Qatar with the North Field East project, the world’s largest gas project.
On its website, Dai Dung also highlights its involvement in other major projects, such as the Phnom Penh International Airport (Cambodia), the Manyar Smelter copper mining plant in Indonesia, and the Power House Parramatta building in Australia.
Most recently, Dai Dung undertook the Misk Ilmi Museum project in Riyadh (Saudi Arabia), valued at $700 million.
For this project, Dai Dung supplied 7,000 tons of steel structures, designed all Tekla Structures drawings, and provided installation services, with a total contract value of $52 million, approximately 1.3 trillion VND.
Additionally, Dai Dung set a record with the world’s largest steel dome, weighing 24,000 tons, at the National Exhibition Center in Dong Anh district, Hanoi. Spanning over 90 hectares, the indoor exhibition area after phase 2 will reach 304,000 m², ranking it among the top 10 largest exhibition centers globally.
On September 16, during the Vietnam Private Sector Economic Forum 2025 (VPSF 2025), the Prime Minister expressed admiration and emotion upon visiting this steel dome, a product designed, manufactured, and rapidly constructed by Vietnamese.
“A project like this, expected to take two years, was accelerated to one and a half years, and then to just 10 months, resulting in a product we’ve enjoyed recently – a truly remarkable achievement,” the Prime Minister emphasized.

The Kim Quy Exhibition Center covers a total area of 10 hectares, with a roof peak height of 57m, currently recognized as the world’s largest dome.
Domestically, Dai Dung has participated in projects such as Long Thanh International Airport, Terminal T2 – Noi Bai Airport, Vinh Airport, Terminal T3 – Tan Son Nhat Airport, Hoa Phat Steel Complex, Nghi Son 2 Thermal Power Plant, Niken Factory, Pepsi Factory, and Da Lat Wool Yarn Factory.
Expanding beyond industrial projects, Dai Dung is venturing into urban transportation infrastructure. Alongside Hoa Phat and Construction Corporation No. 1 (CC1), the company formed the DCH consortium to bid as the EPC general contractor for Metro Line 2 (Ben Thanh – Tham Luong) in Ho Chi Minh City.
With a length of over 11 km and a total investment of 47.890 trillion VND, this is one of the country’s key metro projects. If selected, the DCH consortium will mark the first time a Vietnamese enterprise serves as the EPC general contractor in urban metro construction.
