The Dubai – Fujairah Freeway runs through a mountainous area dissected by several wadi systems. The total length is approximately 44 km. Between Ch 11+000 and Ch 33+400 a series of cut slopes, ranging in height between 13 m and more than 100 m have experienced a range of failures in terms of their types and size. These range from  individual benches to entire cut slope failures. In many of the cut slopes the benches have been lost due to the rock failure.

Sering carried out the review of the condition of the existing slope cuts and the design of the protection works. The remedial works design has been developed on the basis of the observation of the slope stability behavior in the period after the completion of excavation work and on the basis of the geotechnical survey (Observational Approach). Interventions interested 68 slopes and included stabilization actions to provide adequate safeguard against collapse and protection measures to provide safety of the end-users against  the hazard of rock falls.
