Civil Engineering Segment
We carry out civil engineering works for bridges, expressways, tunnels, MRT, port facilities, water and sewage facilities and other infrastructure works. Since our establishment in 1969, for a period of over 40 years, we have undertaken and completed a wide range of civil engineering projects for both the public and private sectors in Singapore. A number of these projects have been conferred “Construction Excellence” awards and are recognised landmarks in Singapore. As at the Latest Practicable Date, all our current projects are based in Singapore.
Since our commencement of business, our major customers include government and government-related bodies of Singapore, such as the LTA, the HDB, the PSA, the PUB and the CAAS.

Building Materials Segment
We procure and sell building materials, namely, concreting sand and aggregates, for building and construction purposes mainly for Singapore public sector contracts. Our building materials are sourced from different suppliers locally and overseas.
Prior to 2006, we had sourced for and supplied building materials for our direct use as well as to sub-contractors in connection with our projects. In 2006, as a result of changes in market conditions, namely the uncertainty over the supply of building materials from Indonesia, we decided to leverage on our procurement experience to explore market opportunities. Currently, our main sources of supplies are from Malaysia and Myanmar.
We mainly sell concreting sand and aggregates to the HDB, a government-related body of Singapore. Our contracts with the HDB were secured either through public tenders (based on advertisements in the newspapers, government website and other mass media publication) or through invitations to tender.
