This research chapter aims to understand the challenges of marketing in quantity surveying firms and the causes that contribute to these problems. The research was conducted with the interpretivist paradigm and an inductive approach. Data was collected through semi-structured interviews conducted with directors of South African quantity surveying firms based in East London, Port Elizabeth, and Queenstown. Thematic narrative analysis revealed that the industry believes marketing knowledge is mostly experience-based. Additionally, the quantity surveying client is difficult to market to, and that marketing does not play a sufficiently significant role in quantity surveying firms. The research was conducted in the Eastern Cape, where public projects account for most construction projects. Marketing is only necessary for private clients; therefore, the results may differ in provinces where private projects form a more significant portion of the total number of projects. This research presents the challenges hindering quantity surveying marketing and can determine what needs to be done to mitigate these challenges. This chapter contributes to the limited amount of existing literature on marketing in the construction industry and identifies the challenges of marketing in quantity surveying firms—a topic that is not sufficiently researched or discussed.
