This paper examined the trend in market prices of some construction materials over a 15-year period in Nigeria and compared the trend with trends in some economic variables during the same period. The purpose of the study is to determine the impact of the trend in the prices of construction materials relative to the behaviour of the nation’s economic variables. Market prices for the chosen materials were obtained from a wide range of sources. Limited project sites and some selected government institutions were also consulted. Market prices were considered for a base period in 2001 in Osun and Kwara States to determine the extent and nature of the relationship with key variables that researchers’ literature has suggested are price-affecting macroeconomic variables. The study showed an increase in the prices of materials, and a trend in increase in the data. The challenges in price predictability and variance occurred in inverse proportion to both the inflation rate and the GDP.
