D.Comm. / The South African Petroleum Industry is very competitive and is vital to the economic growth of the country. It is the basis for much of the nation's productivity, from keeping national transport flowing to producing products and services. The South African Petroleum Industry Association (SAPIA) was formed to further matters of common interest amongst competitive providers of Petroleum Industry Road Conveniences (PIRCs), and to promote good ethics, high industrial standards, competent governance and effective communications within the industry. PIRCs are distributed on most South African roads. This study emphasises and focuses on the location of PIRCs on national routes only. Various factors and theories, which influence the location of a PIRC, are analysed by means of a literature study, personal investigation and practical experience. Attention is given to the physical and legal aspects, which can influence the location of a PIRC. Thereafter, the macro, market and micro considerations are discussed. Particular attention is given to Porter's Five Forces of Competitiveness and the value chain.
