Oman has invited prequalification bids for the construction of its second international airport, which is expected to cost up to $200 million, a tender board official said.

"Bids are open for both local and international companies to build the airfield and infrastructure of the Duqm airport to international standards," the official told Reuters.

He said companies had until September 22 to submit bids.

Duqm will be Oman's second international airport after Muscat, the capital.      

"It is difficult to say how much the airport would cost but the government has set aside a budget of around $100-$200 million for this project," he said.

Duqm is earmarked for major projects, including a refinery, a shipyard repair facility and tourist resorts. - Reuters
