  • Abstract:
    Cost estimation model serves as a framework for forecasting the probable cost of proposed construction projects. It can be classified either as traditional or non-traditional depending on the cost variables formulation. However, in the building industry, quantity surveyors traditionally estimate the initial cost of building projects using the traditional models, which have been criticized overtime for its inaccuracies. This paper therefore aims to examine barriers for the utilization of non-traditional cost estimating models. Design/methodology/approach By using a questionnaire survey, respondents were invited to rate their level of agreement on 23 barriers identified from literature and interview (expert’s opinion). Findings Based on factor analysis inefficient techniques, perceptions of model techniques, unavailability of cost data and lack of understanding and unstable economic conditions were identified as barriers to the utilization of non-traditional cost estimating models. Practical/implications Findings demonstrate that there is need for quantity surveyors to get adapted to utilization of non-traditional cost models which offers better accuracies than the traditional approaches in their quest to improve their professional practices. Originality/value This study demonstrates that there are barriers to the utilization of non-traditional cost estimating models in the Ghanaian construction industry, as evident of this will help in policy formulation for the improvement cost estimating practices.
