About construction companies in East Africa

The East African construction boom is real and ongoing. Kigali's skyline has transformed in a decade. Nairobi's expressway, Mombasa's port expansion, Dar es Salaam's bus rapid transit, Kampala's flyovers, and the Standard Gauge Railway have all created sustained demand for contractors, civil engineers, plumbers, electricians, roofers, and interior finishers, and for the suppliers behind them in cement, steel, glass, and finishing materials.

EABD lists residential and commercial builders, civil-engineering firms, specialised tradespeople, equipment hire companies, project managers, and architects working across the region. Verified profiles include registration numbers (where applicable in each country), past projects with client approval, and the kind of detail a procurement team actually needs to make a shortlist, such as company size, location, areas served and ratings from previous clients.
