Onet has an active geographical presence in 7 countries and provides services in over 20. Our geographic development takes different forms: the realization of projects following bids, acquisitions, local partnerships and joint ventures, etc.

Our approach is to sustainably develop our business according to the target country and the business



Our objective is to give a structured international dimension to the ONET Group, which will create a substantial and lasting presence outside France operating a broad range of activities. The aim is to achieve an international turnover representing 20% of total Group turnover by 2018.


To achieve these goals, Onet has created a division in charge of the development and management of these international activities with a dedicated team that relies on a precise methodology:

A direct approach


  • To consolidate and develop existing subsidiaries to achieve a critical size in each country to be recognized as a reference for all contracts.
  • To develop the Group's activities, through acquisitions among other means, in new countries which have been carefully selected based on their growth potential.


An indirect approach

  • To propose the Group’s specialized expertise in engineering to countries with needs and investment plans in infrastructure.
