Investigating the effect of materials quality control on defects in buildings in Kampala.

Abstract

Errors on construction sites occur frequently and can be costly for the contractors and owners of constructed facilities This study aimed at investigating the effect of materials control on defects in buildings in Kampala. The study specifically assessed the main causes of defects, determined the rate at which quality control was implemented and Identified ways how to control the costs of quality. The research was basically qualitative and quantitative in nature whereby questionaires were issued out to construction professionals in order to collect the required data and existing information in journals and articles on the internet. The data was finally annalysed using Microsoft excel program and SPSS and discussions and interpretations were done basing on the annalysis. The study revealed that a few of the studied construction sites in kampala effectively adopted quality control and assurance procedures which implies that the bigger percentage were not effectively using them. This could ultimately lead to defects in buildings. For defective building to be controlled, the study recomended alternate ways which included; ensuring supervision and corrective checks for materials, through coming up with a quality system that includes employees and by ensuring qualified professional personnel are employed for the project.
