The Company was founded in 1952 as See Yong Construction. In 1980, it was restructured to acquire its present name of "See Yong & Son Construction SDN BHD” or "SYS” for short. SYS is well known in river and coastal projects as well as in irrigation and drainage throughout the Peninsular Malaysia, and is active in Sarawak since 1983. It is also active in marine projects such as construction of jetty, wharf and breakwaters. An important activity was added to SYS when it acquired its first cutter-suction dredger in 1985, to become the first local pioneer in dredging and reclamation works. Since then, additional dredgers and marine plants have been acquired and experience accrued through hands-on experience.
