This selection of civil engineering companies in Africa includes both large established groups and public entities. Key players include Groupe Cosider, based in Algiers, specializing in civil engineering projects, and Stefanutti Stocks Civils from Chloorkop, a leading contractor in Southern Africa focused on reinforced concrete construction and infrastructure. The Kenya National Highways Authority, headquartered in Nairobi, is responsible for managing and improving national highways, while NOVEC, from Sala El Jadida, is an engineering company providing diverse services.
A notable pattern among these companies is the significant presence of public or state-affiliated organizations, such as COSIDER CANALISATIONS SPA, a public economic entity in Alger, and LABORATOIRE PUBLIC D'ESSAIS ET D'ETUDES (LPEE) in Casablanca. Many of these firms, like Ghana Highway Authority founded in 1974, have long operational histories, indicating a mature sector with substantial governmental involvement in infrastructure development across the continent.

How this list is built
Every company on this list has a Tamtam company profile. The industry is the one the company gives on LinkedIn; categories such as SaaS or fintech are classified by Tamtam's AI from the company's website and LinkedIn page; and the headquarters city must match the company's own address. Companies are ranked by the number of employees on LinkedIn, and the list is refreshed every night. Classifications can be wrong, so treat the list as a starting point rather than an official ranking. Last updated Nov 13, 2026.
