Our Key Milestones

Soon Li Heng Civil Engineering started as a humble transport service provider in the construction industry and has evolved and grown as one of the leading specialist earthwork Contractors in Singapore today.



Over the years, the brothers saw opportunities to move up the value chain and started to carry out sub-contracting works through the provision of a complete supply chain of excavation, earth moving and trucking services. And in 1994, Soon Li Heng Civil Engineering was incorporated.


The history of our group dates back to 1975 when our four founders, Mr Ong Yew Lye, Mr Ong Gim Loo, Mr Ong Gim Leong and Mr Ong Gim Giap came together to establish a business in the provision of building materials transportation services for construction firms.


In the late 90s the brothers realised a potential market in the rental of mild steel plates to the construction industry and ventured into the trading and rental of steel products. Pioneering the steel plate rental industry in Singapore, Soon Lee Heng Trading & Transportation since its incorporation as a private limited company in 2004 has established itself as a leading player in the business.


In 2011, as part of our initiative to promote sustainable construction, the group diversify into the green industry and started recycling concrete aggregates from construction and demolition waste and to better position itself as an environmental solutions provider, Soon Lee Heng Eco Engineering was incorporated in 2014.


Together, these four brothers worked on a series of civil engineering projects and contributed significantly to the changing skyline of a fast growing Singapore. Our companies were responsible for a list of prestigious projects which includes the Marina Bay Sands Integrated Resort, South Beach Mixed Development and several Land Transport Authority underground rail network projects.
