The world is changing fast and keeping up takes foresight and planning. In Singapore, what is being done to ensure that we stay relevant when it comes to global competitiveness? What about making the everyday lives for our citizens smooth and liveable? And how are we being responsible global citizens when it comes to environment? Small steps can be taken but in this series, we look at the mega projects that have been undertaken to address those questions. We look at the construction of T5 at Changi East and the Tuas megaport; the development of Jurong Lake District and the North-South Corridor; as well as the building of phase two of the Deep Tunnel Sewerage System (DTSS) and the Integrated Waste Management Facility (IWMF). What are the challenges faced and the innovations underway? What can we expect when these projects are completed?
