Notable concrete products used in Ghana’s construction industry are precast septic tanks, box and pipe culverts, fence posts, concrete poles, roof tiles, precast beams and columns, pavement blocks and slabs etc. Though the variety is large, there exists significant price disparities for the same materials across markets in Ghana. This study assessed differential pricing of concrete products on the Ghanaian construction market with the objective of ascertaining the determinants and causes of differential pricings, and the effects of these differentials on the construction industry in three major cities (Accra, Kumasi and Sunyani) in Ghana. Price data was collected, collated and analyzed from the three cities and the determinants, causes and effects of differential pricings were assessed and ranked based on existing literature. An overall assessment indicated that the main determinant of differential pricings was material input, whereas cost of production was the highest ranked cause of differential pricing. Uncertainties during project estimation which include taxes was also seen to be the highest ranked effect of differential pricing. It is recommended that drastic steps be taken by Government to reduce the uncertainties such as subsidizing some taxes on the importation of raw materials and the use of other inputs in producing concrete products.
