Aurecon Thailand was appointed by Kama JV to provide a design consultancy service for the building envelope of the Main Terminal Building at Suvarnabhumi Airport, Bangkok.
Aurecon’s scope of work included the concept design of the glass wall and support system, witnessing of the performance test and load testing of the cables and associated support clamps and site surveillance during construction.
The Main Terminal Building was developed by Airports of Thailand (AOT) and the Japan Bank for International Cooperation (JBIC).
Suvarnabhumi Airport’s main terminal’s characteristic envelope is 30 metres high and runs throughout the perimeter for a total of 1,100 metres, utilising a minimalist structural form of point fix glass supported by a cable truss system. The structure relied on previously establishing tension in a highly compacted 14mm-diameter stainless steel cable supported by compression spreader strut elements between two vertical trusses to provide a horizontal truss system.
Dead loads are supported by 16mm-diameter high tensile stainless steel rods that were engineered right inside the main body of the point fix clamp making the DL rods to appear hidden within the glass silicon. A concertina extruded aluminium assembly provides a movement joint at the top of the glass wall.
