The 24-month contract, which is to start this month, involves the construction of a beach-front resort including a 309-room 5-star hotel and 77 hotel apartments, to be operated by Kempinski Hotels. The plot is approximately 40,000 m2, and the resort will be built to a maximum five-storey height plus basement car parking.

Carillion chief executive Richard Howson said: "We are delighted to have been selected to deliver this contract, which follows a number of significant recent contract wins in Oman and reflects Carillion Alawi's reputation for delivering high-quality projects. We look forward to continuing the strong relationship we have already established with The Oman Hospitality Company SAOC and to working together to deliver this prestigious hotel."
