CLIENT: UTE FERROVIAIRIA CENTRAL (RUBAU)
During 2010 and 2011, Colombia suffered its most devastating natural disaster of the last 40 years, the La Niña phenomenon. Its effect was such that it overwhelmed the normal response capacity of the state, leaving more than 700 municipalities affected and communications systems seriously damaged.
In 2013, the Unión Temporal Ferroviaria Central commissioned Esteyco to design the solutions for preparing and protecting an initial set of 50 (successively increased to 70) critical points identified along the alignment of the central railway system running parallel to the River Magdalena. The repairing of these affected points allowed the resumption of railway traffic on a section of track of more than 500 km crossing the departments of Antioquia, Santander, Cesar and Bolivar, essential for the coal trade.
Given the features of the sitesand logistical difficulties of access, all the works were designed to take maximum advantage of the area and to favour its integration into the natural environment. The actions designed included the application of high performance geo-synthetic materials (geo-cells and geotextiles) to protect the abutments of bridges, the stabilising of hillsides affected by mass movements, the improvement of the track drainage and the reinforcement of the platform.
