ViaCon provides hydraulic steel culverts as pedestrian and animal crossings for major railway project in Awash-Kombolcha-Hara Gebaya, Ethiopia.
The Challenge
When Turkish construction contractor Yapı Merkezi took on construction of the 426-km-long Awash – Kombolcha – Hara Gebaya single-track railway project, they were signing on to com-
plete an important infrastructure connection between northern and eastern Ethiopia to support passenger freight rail as well as import-export coming through the port at Djibouti.
In planning the project, one of the biggest considerations was the selection
of materials. With more than 1,000
hydraulic culverts and 60 underpasses as part of the project, convenience and speed of transport was a critical criterion. are no concrete production facilities anywhere along the railway line.
The Solution
Corrugated steel made the most sense for ease of transport and speed and flexibility of construction. ViaCon’s MultiPlate corrugated steel structure solution offered an economical option for the contractor.
The ViaCon Advantage
Time and cost savings were achieved in the construction of the Awash-Kombolcha-Hara Gebaya Railway Project.
