A major corridor in Colombia collapsed after a harsh winter. SGS has been helping to stabilize unsteady sites.

The Honda-Manizales corridor in Colombia connects the western part of the country to the capital. It plays a major role in the Colombian economy, as it is used for the transport of farm products.  In 2012, after a harsh winter, the corridor collapsed.

In 2013, as part of an initiative to increase investment in road infrastructure, the Colombian government awarded SGS ETSA a contract to supervise the stabilization of unsteady sites along the corridor. ETSA, which was acquired by SGS in March 2012, had already been developing designs for unstable sites there over the previous two years.

Identifying and Solving Problems

During the preconstruction phase, SGS experts used geotechnical, hydraulic and geological studies to determine the main triggers of landslides in the zone. During construction, they are helping to implement solutions by providing technical support in areas such as:

  • Road design
  • Transportation
  • Geotechnical services
  • Administration

SGS has been supervising construction of various works, including retaining walls, shotcrete walls and reinforced embankments. It has also been ensuring that the project stays within budget.

Work is being conducted on site and in concrete, soils and pavement laboratories.

Making Improvements

By helping to restore the collapsed corridor, SGS is helping to lower transportation costs and improve living conditions. SGS has also been providing consultation and supervisory services for other projects in the region. For example, in 2014, it was involved with the design of aqueducts and sewers for 19 towns in the department of Tolima.
