dc.description.abstractCompetency is the knowledge, skills and attributes needed in an organization or area of operation to enhance high productivity. Construction waste could also be defined as an unusable or unwanted material at the construction site. There is low level of awareness on key competencies that drive waste minimization at the construction stage of a project. The awareness and the implementation of the various competencies that drive waste minimization ensure proper collaboration among construction stakeholders as well as a positive attitude towards waste minimization to enhance high productivity. This study was designed with the aim to explore the key competencies that drive material waste minimization at the construction stage of projects. An in-depth literature review and a pilot survey were done. Through that, questionnaires were designed and administered to Public Procurement Authority (PPA) registered construction firms in the Ashanti Region with much focus on Construction Managers. Data generated from the field survey of a sample size of sixty-nine (69) respondents was subjected to Relative Importance Index, Factor Analysis, and Kendall’s Coefficient of Concordance. The findings of the study revealed Awareness Competency (AC), Managerial Competency (MC), Personnel Ability Competency (PAC) and Communication Competency (CC) as the key competencies that drive construction material waste minimization. Poor Workmanship, Challenges arising from Transportation of construction materials, and Poor Supervision were highly ranked as the causes of material waste at the construction stage of projects while Increased purchased quanti0ty and price cost, Poor site organization and obstruction of movement due to excessive waste generated, and Lower business patronage were also ranked as the effect of construction material waste variable in undertaking construction projects. A future study is thereby proposed by this study to explore the role of construction professionals in material waste minimization.en_US
