Project Description

The study includes: topographic survey of the road; geotechnical study and laboratory tests; final design of drainage and reinforced concrete containing walls structures; final design of 4 reinforced concrete bridges. (Pont Nyan 93,80 m ; Pont Nguibi 21,80 m ; Pont Kouba 69,80 m ; Pont Mabor 21,80);; bill of quantities and estimates; preparation of tender dossiers. The Ngaoundere-Touboro-Moundou section is embedded in an interregional program that should make easier the link between Chad (Moundou) and the railway station of Ngaoundere, and then the transcameroonese railway to the Douala port. Such link depends on cotton export, of which Moundou is the collection center of Chad. The new road reduces the time to the Ngaoundere station of approximately 300 km. The study includes three solutions for the road superstructure: soil, bicouche and bituminous conglomerate. The economic study includes traffic analysis, economic analysis concerning the development of three countries (Chad, Central African Republic, and Cameroon), an analysis concerning the rehabilitation of the transcameroonese railway line. 3 variants have been planned: from the Ch 0.00 to the Ch 6 + 673 (F CFA 4.537.746.864), from the Ch 50+281 to the Ch 66+363 (F CFA 2.683.140.496) and from the Ch 162+686 to the Ch 188+336 (F CFA 17.311.716.213). To conclude, a design has been executed for a “Tranche Conditionnelle” to cross Moundou city.
