Explore our Past and Current Projects!

As aforementioned, Mass Rapid Transit(MRT) projects are a mainstay in our portfolio. Our Managing Director, T.T. Koh believes not just in meeting the business needs, but contributing our services towards social good and playing a part in nation-building.

KKL continues on this philosophy as we embark on the upcoming North South Corridor (NSC) project, an underground highway that will bring great convenience in alleviating the congestion on the existing CTE.
