The expansion of Muscat International Airport is back on track after Oman awarded US firm, Hill International, a two-year contract worth $108.5 million, to supervise the project.
Hill International will replace Danish consulting group COWI, a transport ministry statement said.
The ministry has chosen not to renew COWI’s original contract, signed in 2008.
Oman is expanding the airport's terminal building and the airfield in a project that has been dogged by delays.
The expansion, worth $7 billion, was originally planned to be completed by the end of 2012.
It is now scheduled for completion by late 2014. Hill International's contract started on January 1, 2013.
Oman is also extending Salalah Airport in the south and building new airports in Sohar, Ras Al Hadd and Duqm.
