DUBAI, May 25 (Reuters) - Kuwait is expected to sign within two weeks a $1 billion contract with Italy’s Salini Impregilo and Turkey’s Limak Construction for its planned South Al Mutlaa City project, an official said on Wednesday. It is the first phase of the planned 100,000 square kilometre urban development, which is situated in central Kuwait and is expected to house around 400,000 residents when completed. The Gulf state will also sign a contract this month worth between $80 million and $90 million with Hill International to manage the building of the entire city, Khraibut said.
