The SR300m ($80m) contract covers runway renovation and maintenance at Najran, Al-Taif, Buraydah, Hail, Al-Wajeh, Ar Ar and Qourayat. The work is expected to take two to three years.
In a separate contract, the contractor secured a further SR300m contract for the construction of new terminal buildings at Najran airport.
The awards are part of a wider effort by Saudi Arabia to update its aviation infrastructure.
Together with its new contracts, Al-Mabani is currently working on a SR1bn contract to upgrade and renovate the airfield of King Abdulaziz International Airport in Jeddah. It is also carrying out works at Tabuk and is due to complete further work at Yanbu airport in the coming weeks.
