Abstract

This study sought to assess the effect of quality assurance practices on construction efficiency in the case of the Tanzania National Roads Agencyin Kilimanjaro region. Specifically, the study examined the effect of quality planning, quality control and process audit on construction efficiency. The lean construction theory and a post-positivist philosophy were employed in this research study, which adopted a quantitative approach and an explanatory research design. The population of 215 employees was selected using simple random sampling technique, gathering primary data through a self-administered questionnaire and secondary data through a thorough review of relevant documents. Data was analyzed using descriptive and inferential statistics with the help of SPSS version 26. Findings showed that quality planning contributes significantly to timely project completion and optimizes material and resource use while improves stakeholder coordination. Also, the study revealed that quality control contributes significantly to timely project completion, optimizes material and resource utilization hence enhances stakeholder coordination. The study unveiled that process audits identify inefficiencies and areas for improvement, reduce errors and delays hence enhance reliability and consistency in construction. The study concludes that quality planning, quality control, and process audits positively impact construction efficiency and recommends TANROADS enhance quality planning, strengthen quality control with advanced technologies and training, and prioritize regular process audits. Future studies should explore applying quality assurance practices from other industries, like healthcare and manufacturing, to construction. Keywords: Quality Assurance, Quality Planning and Quality Control
