At the beginning of the 20th century in the south of Tunisia, Ahmed BOUCHAMAOUI created a civil engineering company in the small village of Bouchamma ( Gabés ).

In 1948 his three sons took over responsibility of the company. Since then BI has continued to develop and expand its activities, not only in Tunisia but also in Libya on number of integrated agricultural projects.

Over the course of the 1970s  , the evolution of the company from a building and civil engineering contractor to an industrial contractor in the energy sector was a natural development, given the growth of hydrocarbon activities in Tunisia and its neighboring countries.

Today, Stakeholders of the company are committed to meeting the challenge of continual improvement and maintaining the achievements of the past century.
