Air Traffic Control Tower Muscat International Airport – Construction

In 2014, Carillion Alawi was selected to design and build the tallest occupied building in Oman, the new Air Traffic Control Tower for Muscat International Airport. The Ministry of Transport and Communications selected Carillion Alawi because of our significant experience and expertise in managing state-of-the-art technology and construction projects.


The Air Traffic Control Tower is almost 100m high with a visual control room cabin designed with uninterrupted 360-degree views of the airport aprons, taxiways, and runway approaches.

  • Carillion Alawi installed a state-of-the-art console prefabricated in Europe. It was installed using a unique crane system mounted on the tower’s roof – speeding up installation and providing a safe, secure working environment.
  • A visual control room was constructed to a high specification, meeting international strict acoustic specifications, and withstanding extreme temperatures.
  • A roof-mounted building maintenance unit was installed to facilitate the cleaning and maintenance of the external façade.
  • The base levels were built with sheer walls and external walls combined with colour bonded metal sheets and natural stone claddings, providing the client with structural and aesthetic requirements.
  • Carillion Alawi utilized an innovative RMD Kwikform self-climbing wall formwork system, Tru-Lift, to construct the Air Traffic Control Tower. This system was safe, quick, and easy to erect, and it meant that the platform and formwork could be crane handled in one operation, reducing crane time, speeding up concrete cycle times, and reducing programme time on multi-floor builds.
  • Carillion Alawi took an innovative approach and used pre-insulated ductwork that used a fraction of the galvanized sheet steel ducting weight.
