Refurbished at a cost of S$500 million, the grand old dame at Singapore Changi Airport has finally lifted its curtains after almost four years of upgrading works. Based on the ‘Tropical City’ theme, improvements were made to the façade of the terminal and airport facilities were enhanced to improve the overall airport experience for passengers to Changi.

Meinhardt were the Structural and MEP Engineer for the S$500 million Terminal 1 (T1) Upgrading project.  The upgrading result has given the terminal a fresh and rejuvenated look. Works were carried out to refurbish the terminal’s interior design and finishes, as well as improve passenger flow at key areas such as the Departure Check-in Hall, Departure Transit Mall and Arrival Hall. About 240,000 sq ft of floor area has been added to the building, bringing the total floor area of T1 to about 3.3 million sq ft. The larger floor area provides for more spatial comfort, better passenger flow, additional facilities and expanded retail and F&B offerings. Improvements to the façade and terminal facilities were done with the aim of improving the airport experience for passengers. Higher ceilings, improved lighting, wider thoroughfares and thoughtful landscaping have all contributed to a high quality experience. A major challenge facing the project engineers was to carry out the upgrading even as T1 remained operational. This meant that works had to be done in phases during the four-year period to accommodate the different operational requirements of the terminal’s users.
