PM Lee Hsien Loong spoke about the plans for T5 and Changi East in his National Day Rally speech.

Land preparation works for Changi East and planning for T5 begin in 2014, including functional design studies and concept development for the terminal.
2018
CAG announces the appointment of the Master Building Consultants (MBC) in 2018, to provide architectural design and engineering consultancy services for the development of T5. The Master Civil Consultants (MCC) are also appointed, to provide consultancy services for the design of infrastructure at the landside and airside areas outside of the T5 buildings.
2020
A two-year pause of the T5 project is announced in 2020, due to the Covid-19 pandemic. The aim is to assess the impact of Covid-19 on aviation growth, learn from the pandemic experience, and review T5’s design to meet the needs of post-pandemic travel.
2022
The resumption of work on the T5 project is announced in 2022. MOT, CAAS and CAG have taken the opportunity of the two-year pause to comprehensively review the T5 design to make it more modular, resilient and sustainable. Construction of T5 will commence in about two years for T5 to meet the anticipated demand for air travel around the mid-2030s.
2025
PM Lawrence Wong breaks ground for Terminal 5. Works will start thereafter. Several contracts for remaining buildings, civil works and systems are expected to be launched in the next few years.
