The paper deals with the facets of work by the Croatian architect and urban planner Branko Petrović in Addis Ababa, where he served as the chief architect in the Ethiopian Ministry of Public Works and Communications from 1962 to 1969. Translation of the expertise stemming from the domicile practice and adaptation to a specific construction momentum in the city are thereby being considered. The modalities of technical cooperation are simultaneously examined as a form of international knowledge exchange in the field of architecture.; Rad se bavi facetama djelovanja hrvatskog arhitekta i urbanista Branka Petrovića u Addis Abebi, gdje je od 1962. do 1969. godine bio glavni arhitekt Ministarstva javnih radova i komunikacija Etiopije. Pritom se razmatraju aspekti prijenosa znanja proizlazećeg iz iskustva domicilnih praksi i prilagodbe situaciji građevinskog zamaha bez presedana u razvoju grada. Istovremeno se ispituju modaliteti tehničke suradnje kao forme međunarodne razmjene u domeni arhitektonske profesije.
