This paper highlights the benefits of adopting and implementing a tailored lean construction strategy with its dynamic action plans during the construction phase of one of Qatar's recently completed infrastructure projects. The study includes using various enhancement measures and criteria combined with best practices by different project teams from all involved parties. The paper also proves the influence of producing a systematic work process during the project life cycle on overcoming challenges and barriers, in which the critical elements of accomplishment, improvements, and the conditions of satisfaction are adequately outlined and recorded. Through this paper, the lead author claims to achieve one primary goal, which is to name the most crucial barriers that affect the deployment of the Lean Construction concept within the construction industry based on data collected from four infrastructure projects, including the evaluated one in this paper. The required data was collected and collated through questionnaire surveys conducted on 57 professionals following many interactive workshops held by the lead author about the importance of Lean Construction implementation in construction projects. Concurrently, data analysis outcomes were used in the PDCA cycle of continuous improvement. The findings emphasize the importance of leadership engagement in lean deployment processes, and training sessions/workshops, besides rewarding the project team members as a pillar towards an ideal productivity level with the practical usage of resources and delivering the utmost value to the client.
