Amman's Queen Alia International Airport (QAIA) has reappointed WSP and Consolidated Consultants (CC) to head the second phase redevelopment work at the airport.
The companies will act as independent engineers for the construction of the new passenger terminal that will cost around $800m.
The terminal will be built under a public-private partnership (PPP) agreement between the Hashemite Kingdom of Jordan and Airport International Group, the airport concessionaire.
Both the companies have provided independent engineering services at the airport since December 2007. The first phase of the redevelopment was opened in 2013.
The joint venture has been reappointed by the project financiers, led by the World Banks' IFC and the Islamic Development Bank (IDB), to provide technical advice and support related to the project financing.
With the expansion of the new terminal building, the airport aims to increase its capacity to 12 million passengers per annum.
The phase will cost around $100m and will involve the demolition of the old terminal building and the building of seven new contact stands and the construction of other support services.
WSP director Jim Ratliff said: "Our re-appointment to this high profile project reflects WSP's increasing presence right across the aviation sector, from front-end planning to design and environmental consultancy. We have worked on several of the world's largest airports such as the new Hamad International Airport (HIA) in Doha, which is ongoing, and Heathrow/Gatwick Airports so this just consolidates our offering.
"In the UK our structures, building services and acoustics teams are helping to further upgrade Heathrow Airport and we have just finished a connectivity study on Leeds Bradford International Airport (LBIA)."
