This paper reveals field survey of ten year price distribution and the degree of uncertainty or dispersion in the size geometry of local and imported bars. The study separates cost price and strength the main parameters needed when selecting ideal steel rebars, which is very fundamental to the development of reliable standard of practice for building and civil engineering industry. Lagos highland especially Ogba reinforcement bars sample has the highest mean, standard deviation and coefficient of variation (COV) of Y25 (24.8), Y16 (σ0.095) and (0.81%) respectively. Likewise, the study of the price from various Lagos zone (island and highland) would enable the engineers, project managers or clients construction professionals to assess whether the price different or matches the strength difference. Finally, the research investigation is a basis for the development of acceptable standards or codes of practices for design that takes into account the geometry and strength of materials for construction of RC building and civil infrastructure in Nigeria.
