EVERY day, commuters pace up and down the escalators at Singapore's Mass Rapid Transit (MRT) stations, but few know who is behind the civil engineering works there and in some, the exquisite beam structures of these escalators.

SIAC Pte Ltd is the name behind some of Singapore's prominent local infrastructure works. Its diverse portfolio includes works on MRT platform screen doors, designing and building of school auditoriums, construction of the Star Performing Arts Centre and, more recently, the installation of over 4,000 SIAC doors across a variety of projects, including the new Ng Teng Fong General Hospital.

The company's business model involves all aspects of a project - from the initial diagnosis of customer requirements, procurement, manufacturing, installation and finally to maintenance - taking charge of multiple operations from start to end.
