    The development of location adjustment factors for construction price estimating in Nigeria

    English: This article explored the use of Location Factors (LFs) as an empirical tool for converting construction price at one location to price at another location. The objective was to generate LFs for selected locations to provoke interest in the concept. Firstly, locational factors influencing construction price were identified from literature. Then, based on a hypothetical project and using Lagos, Ibadan, Port Harcourt and Abuja as pilot locations (with Lagos as the base location), LFs were calculated for the four locations. The LFs obtained were validated using tender prices for the primary school projects of the Universal Basic Education Programme financed by the Federal Government of Nigeria. The results showed that tender price levels were higher in Abuja and Port Harcourt and lower in Ibadan, compared to Lagos (the base location) on the basis of their location differences. Although the results underestimated the actual values of the LFs by only 8%, which is well within the acceptable level of early price estimating accuracy for quantity surveyors, the insufficient and scanty data used limits their statistical reliability. It is hoped that more detailed studies, based on more locations and using more project samples, would be carried in the near future to further the development of LFs for construction price estimating in Nigeria.
