Changi Airport International (CAI) is discussing with the Philippines' Department of Transport and Communications (DoTC) to help refurbish Manila's main international terminal.
CAI confirmed it has been approached to play an "advisory role" in the upgrade of the 30 year-old Ninoy Aquino International Airport Terminal 1 (NAIA 1).
"We will be sending a team to Manila to define the scope of the work," said a CAI spokesman.
He added that CAI's advisory role is expected to cover areas., such as terminal renovation, capacity enhancement, systems upgrading and improving terminal operations and passenger service quality.
The team will complete its study in January 2012 and discuss the proposed engagement with the DoTC.
Last week, President Benigno Aquino approved a Philippine peso (Ps) 1.16 billion ($36.8 million) rehabilitation of the terminal.
Upgrading plans for the terminal includes both the aesthetics and interior design of the facility, such as replacing worn out flooring, ceiling, walls and partitions, while adding immigration counters, creating more space in both the arrival and departure areas and renovating the toilets, the DoTC said.
The building will also need to undergo structural works, the DoTC added.
In addition, a rapid exit taxiway will be built by February 2012 to allow landing aircraft to leave the runway quicker and allow more aircraft to land sooner, easing congestion.
NAIA 1 was voted the world's worst airports by several travel websites this year.
The DoTC is considering a proposal to sell the NAIA because the airport has reached its saturation point with little room for expansion.
The total capacity of the four terminals is 32 million a year and its throughput is expected to reach 30 million in 2011.
The sale could raise up to $2.5 billion, which will help pay for a new international gateway at Clark International airport.
