The Kaust Perimeter Security System (KPSS) Project includes provision of a concrete slab and a culvert at Wadi Khulais towards the sea-outfall. The design consultant has requested SAPMT to provide structural details of similar culverts/ bridges on Wadis being constructed by the Thuwal City Development Project or Thuwal Flood Control Project. This will help them to incorporate the existing features in the interface design of the proposed culvert and also to follow similar principles for structural design and shapes. // It is requested that the design drawings of the existing bridges as shown in the attached drawing be provided so that our design consultant can prepare the KPSS drawings accordingly.
