Qiddiya Geotechnical Investigation


Qiddiya is set to become the Kingdom's capital of entertainment, sports and the arts to meet and satisfy the recreational, social and cultural needs of current and future generations. Located 45km west of Riyadh, Qiddiya will comprise of a resort core, motion zone, city centre, eco zone golf community, aerodrome and airfield future development and green buffer development zones. Overlooking the resort core from its perch 200m above on the edge of the Tuwaiq escarpment will be a city centre mixed-use village dedicated to sports & the arts. Qiddiya's city centre development area covers approximately 530,000m2, allotted across 33 plots.


Our Role

Ayesa was appointed by the Qiddiya Investment Company, to provide geotechnical support for the proposed development in Qiddiya. Our role included identification and detailed requirements for test and investigations by plot, preparation of the required tender documents, review of technical & commercial submissions and providing any additional support.

As the lead geotechnical consultant, our scope included the provision of specifications, drawings, BOQs for pricing and monitoring works during construction, as well as GIS drawings and data.



Ayesa utilised BIM modelling by integrating Holebase SI and Civil 3D along with Autodesk Infraworks. This aided with faster revisions of the site investigation layout to reflect the masterplan layout changes.
