Bessac signs its first contract in Ivory Coast to build a microtunnel in Abidjan.

Bessac Afrique, the Bessac branch formed earlier this year, signed its first contract a few weeks ago with PFO Africa, the market leading construction company in Ivory Coast. A great first which demonstrates the expertise of the Soletanche Bachy group in tunnels and underground works.

As part of the motorway tunnel construction project in Abobo, one of the most densely populated areas in Abidjan, the teams from Bessac will create a 990 metre long gravity microtunnel and 1.8 metres internal diameter to drain stormwater from the low point of the structure to the existing canal on the other side of the city.  

All plant and equipment are expected to be on site by the end of June 2021, and the project will take just under one year to be completed (including the 4-month preparation period). It’s a suitably ambitious project and an excellent success story for this new Bessac entity!
