The document discusses quality assurance and quality control concepts in construction projects based on ISO 9001:2008. It outlines a quality management system with four levels - quality manual, procedures, plans, and forms/records. Key elements include defining roles for QA/QC departments in verifying requirements and monitoring activities. Quality control focuses on inspection, monitoring and reducing variation. The presentation provides an example of applying the quality system to a HOYA construction project, with the goal of zero defects and identifying problems before customers.
