sup>— The construction of building structure involves very complicated undertakings. It requires a trained workforce at the design stage, approval process, supervision, and construction stages. Inferior quality of workmanship is one of the significant issues facing the workforce to perceive and apply the proper construction methods and techniques following the quality control assurance for building projects. This study considered some of the construction stakeholders participated in the implementation of projects in Addis Ababa City. It focused on assessing and investigating poor workmanship on the quality of projects that included concreting works to accessible ongoing construction sites across the study area. It involved determining the cause of low-level workmanship and identifying factors that would significantly minimize the problems and increase client satisfaction. The study comprised of 20 construction sites, of which 55 questionnaires were collected. The data collected are related to the challenges facing the construction industry and concrete quality as well. The causes and strategies applied to improve construction quality were analyzed using the study's variable. Results indicated that inadequate construction management represented a low level of workmanship and a lack of training rated first with RII of 0.9556. At the same time, the Workers' motivation was placed second with RII 0.775. Hence, it recommends close observation of construction management factors like supervision, training, motivation, and good communication on-site to minimize the cost and effects associated with poor workmanship when implementing building projects.
