King Abdulaziz International Airport, Jeddah

A world-class commercial centre and a key travel hub, King Abdulaziz International Airport (KAIA) is the busiest airport in Saudi Arabia, with its expansion being the most important strategic project in Jeddah.

RGF has been active on both of the first two phases of the project. Phase-I was the pre-construction phase and comprised mainly of geotechnical site investigations; in-situ testing of the existing ground down to 200 metres depth. “The site investigations were augmented with necessary laboratory testing and analysis of soil and rock samples retrieved from the ground through drilling of boreholes,” explains Eng. Hamid Ismail, Manager Western Region. “Necessary geotechnical factual reports were also provided to client/consultants at the end of site investigations. All foundations for the buildings and other structures for the new KAIA upgrade project were designed based upon RGF site investigations and reports.”

Phase-II mainly comprises of laboratory testing services  during the construction stage. RGF established material testing laboratories for soil and asphalt on-site. “All backfilling and asphalt paving works are being monitored and supervised in collaboration with the consultant to ensure quality construction works,” Eng. Hamid Ismail, Manager Western Region continues. “Site sampling is performed in the shape of in-situ density tests augmented with laboratory analysis of soil and asphalt samples to ensure that project specifications are being addressed.” All construction materials are tested to the highest industrial standards in RGF ISO 17025 accredited laboratories in Jeddah.

Hydro-geological studies have also been performed for the prevailing groundwater aquifers at KAIA, both during Phase-I and Phase-II of the project. “Several deep wells were dug and pumping tests were performed to determine the hydro-geological parameters of the ground aquifers, including storage coefficient, specific yield, and permeability coefficient. The geochemical environment was also explored at KAIA, with RGF performing a great number of chemical and environmental tests of the soil and groundwater,” Eng. Hamid Ismail, Manager Western Region concludes.
