Abstract: Adoption of lean construction in the construction industry will improve quality and efficiency, eliminate waste and increase value for the client. It is a production-based management strategy that enables construction companies to maximise profits by maximising efficiency and eliminating waste of resources. Lean production efforts in some countries have not been successful due to many barriers to its successful implementation. This study identifies and prioritises possible barriers to successful implementation of lean construction in the Ghanaian building industry and measures to overcome potential barriers. The study adopted a structured questionnaire survey of 400 construction practitioners in Ghana. The factors identified as barriers to successful implementation of lean construction and measures to overcome potential barriers to lean construction were evaluated and ranked according to their mean scores. The five strongest barriers to the implementation of lean construction in Ghana are ranked as fragmented nature of the industry, extensive use of subcontractors, lack of long term relationship with suppliers, delays in decision making and waste accepted as inevitable, in that order. Factor analysis using the SPSS Version 16 package enabled the barriers identified to be grouped under six components as 1) lack of proper planning and control, 2) lack of teamwork, 3) poor project management, 4) lack of technical capabilities, 5) lack of financial resources and 5) poor communication between parties. The results enable building organisations to improve construction quality and efficiency through the implementation of the measures suggested to remove potential barriers to the implementation of lean construction. Identification of barriers and measure to overcome potential barriers are steps towards successful implementation of the lean concept in the Ghanaian building industry.
