The History of Koh Brothers
Koh Brothers Group was founded in 1966 by Koh Tiat Meng as a sole proprietorship in Singapore. What started as a modest engineering and construction business gradually evolved into a diversified infrastructure and property development group operating across multiple sectors.
The company gained momentum during Singapore’s rapid modernization period, when the country invested heavily in roads, drainage systems, transportation infrastructure, and urban development. Koh Brothers became closely associated with public infrastructure projects, particularly flood alleviation and canal improvement works.

Today, Koh Brothers operates across:
- Singapore
- Malaysia
- Indonesia

- Industrial engineering
- Environmental infrastructure
The combination of these capabilities gives Koh Brothers a broad operational footprint within Singapore’s infrastructure economy.
Koh Brothers and Changi Airport Expansion
One of the company’s major recent developments involved infrastructure works linked to Changi Airport expansion.
Reports indicated that a Koh Brothers-linked joint venture secured a large contract involving underground tunnel construction for the future Terminal 5 development project.
The significance of this contract goes beyond revenue size. It reinforces the company’s position as a trusted participant in nationally significant infrastructure works.
Terminal 5 is considered one of Singapore’s largest long-term aviation projects, designed to support future passenger growth and strengthen the country’s position as a global aviation hub.
Winning contracts associated with such projects demonstrates confidence in the company’s engineering and execution capabilities.
Financial and Business Structure
Koh Brothers operates through a multi-segment business structure that includes subsidiaries, associated companies, and joint ventures.
Business Segments
| Segment | Focus |
|---|---|
| Construction & Building Materials | Engineering and infrastructure |
| Real Estate | Residential development |
| Leisure & Hospitality | Hotels and hospitality investments |
| Sustainable Engineering | Water and environmental projects |
This structure provides resilience during market fluctuations. For example:
- Property slowdowns may be offset by public infrastructure projects
