The Infrastructure Works for Muscat International Airport Development Project has been awarded to TAV – CCC Joint venture in August 2009. The duration of the project is 34 months, a challenge for a project this magnitude, which TAV Construction is familiar with.

The works comprise construction of the new runway, apron, power centers, utilities, landside and airside roads. One of the great challenges in building the new airport in Muscat is to provide adequate drainage of the area. The rainwater passes to get to the sea is the stretch of land on which the new runway will be as it is a flat, low-lying area, separated from the ocean only by a coastal road, where water can stagnate in the shallowest spots after powerful but short-lived downpours.

In order to prevent any effect of a possible flooding, the basement level of the terminal building has cancelled and all levels of the infrastructure works on the airfield, runways, apron and taxiway areas have been altered to suit. A several hundreds of meters wide “wadi channel” has been included within the scope of development works as well as three giant outlets with culvert connections  with 500 m3 water capacity per second.
