Dissatisfaction Levels in Turkish Residential Buildings and Recommendations for Improving Quality

Abstract

It is well known that many residential construction projects suffer from low quality due to a variety of factors; therefore, to find out the level of dissatisfaction among stakeholders, the underlying causes, and the recommendations, this study uses a survey. Owners, controllers, and contractors were asked to complete questionnaires online. To rank dissatisfaction levels, incomplete or defective works, and suggestions for improving construction quality, data from the survey were analyzed by frequency indexes (FIs), and project stakeholders’ perceptions were aggregated by “probabilistic or.” The study reveals that 52% of flat owners are somewhat satisfied with the building inspection company’s inspections, but most owners agreed (4.13±0.98) that consultants should inspect the construction, whereas the lowest dissatisfaction (1.71±1.30) is “getting smaller apartments than promised.” Construction dissatisfaction can be attributed primarily to “high-profit expectations by building contractors,” whereas “the lack of sufficient qualified workers,” “the lack of competence of building contractors,” and “incompetence and ineffectiveness of site chiefs/managers” are also prominent. From the perspective of controllers and contractors, the highest consensus (4.43±0.92; 4.24±0.85) is “needing to work with experienced construction site managers,” whereas the lowest dissatisfaction (2.57±0.72; 2.45±1.02) is “the overall quality of constructed residential buildings.” It appears that contractors’ dissatisfaction is lowest (2.42±0.95) when it comes to “contract-conforming construction quality.” A general dissatisfaction rate of close to average is reported by the owners, whereas the dissatisfaction rates of the controllers and contractors are close to “above average.” Based on the findings, this study provides valuable information and recommendations for improving the quality of construction for the successful completion of building projects.
