HIGH-GRADE CONCRETE RUNWAY FOR EXTREME CLIMATE AND LARGER AIRCRAFT
The airport is designed with a robust 3,600 m-long category4E, which is to be constructed from concrete. This means that the runway will be better equipped to withstand the harsh weather conditions of the extreme continental climate. Furthermore, the runway will be able to handle large aircraft like a B747 or A340 in the future.
The new location, the advanced design and installations like a 24-hour all-weather air traffic control system will help to improve the safety and the possibilities of the airport facility. NUBIA has been designed to take 3 million passengers a year, three times more than currently, and the airport will be able to handle ten times more cargo than now.
To finance the airport project, the Government of Mongolia has signed a 40-year soft loan agreement for JPY 65.6 billion with the Japan Bank for International Cooperation. The Mitsubishi-Chiyoda Joint Venture (MCJV) won the contract in the technical bidding. In May 2013, the main construction contract was signed between MCJV and the Civil Aviation Authority of Mongolia. The concrete paving works started in May 2014. The entire construction work was awarded to the prime subcontractor Samsung C&T and the concrete paving work is being carried out by the long-standing Wirtgen customer Sungdo Construction from South Korea. The Korean company is specialized in slipform paving jobsites.
Dongin Park, Samsung C&T Project Manager of the NUBIA project, summarizes the construction challenges: “We have to face the extreme continental climate with short, hot summers and long, icy winters. This gives us a construction time window of only three to four months during summer time. The wind from the Gobi desert and the intensive sunlight quickly dry out the concrete. That’s why the main paving operation with the SP 1600 had to happen during night shifts.”
