US-based Louis Berger has secured a fourth contract extension for independent engineering services at Queen Alia International airport (QAIA) in Amman, Jordan.

The $15m contract involves Louis Berger providing independent engineering services to the rehabilitation and expansion programme. It covers the construction of an additional 46,500-square-metre passenger terminal area, eight aircraft contact gates, eight remote boarding gates, four link bridges that can handle either a single wide-body aircraft or two narrow-body aircraft simultaneously in arrival and departure modes, 10 moving walkways, 15 elevators and 18 escalators.

The finished terminal will have the capacity to process 9 million passengers a year, with the potential site capacity to process 12 million a year. The programme’s completion date is scheduled for mid-2016.

Louis Berger previously worked on the construction of a new 100,000 sq m, 14-gate passenger terminal building, as well as improvements to existing airside and landside facilities.

Queen Alia International Airport is being developed and is operated by the Airport International Group (AIG). It is a Jordanian consortium of companies, and a joint venture of Cyprus-based Joannou & Paraskevaides and J&P-AVAX that won a build, operate, transfer contract for the airport in 2007.
