Track and Mountain Roads in Different Location in Different Governorate and Wilayat

Narrative Description of the Project:

The project comprised the study of (8) track roads existing within a total corridor length of 71 km. Upon subsequent design the length of track road was actually 140 km due to the numerous "hair-pin" bends required to achieved an acceptable vertical grade (up to 15%). The track roads are located in various locations within the Northern Hajar mountains, with the purpose to provide safer access to remote villages. The project had a budget that would only allow the minimum standards. The project was challenging in that numerous alignment iterations were carried out to achieve the optimum cut and fill.

Description:

1) Renardet identified the project by site visits with the local leader of the village and a representative of the Ministry to define the start and end points for each track road
2) A survey boundary was established and the survey sub-contractor commissioned to carry out aerial survey using a drone (UAV)
3) Renardet created DTMs and base mapping for the study and design. Using highway design software "Prost" a process of evaluating different alignments in consultation with the Client was carried out. To achieve the final design output a balance between cost and acceptable standards was achieved
4) The designs were finalised and tender documents comprising Prime Document, Specifications, Drawings and Bill of Quantities were completed
