Selim Bora has had quite a run. In March his company, Summa, won a contract to rebuild and run Guinea Bissau’s new international airport. Months earlier it had completed a 50,000-seat national stadium in Senegal, after less than 18 months of work—a sprint-like pace for such projects. The company’s résumé also includes convention centers in the Republic of Congo and Equatorial Guinea, a sports arena in Rwanda, and airports in Niger, Senegal and Sierra Leone. "Ten years ago we had no projects in Africa outside of Libya,” recalls Mr. Bora, taking in the view from his office in Istanbul. "Today 99% of our work is in Africa.”
