The level of quality management in the construction industry has been on a drastic decrease over the past years. Application of lean thinking principles in construction have been identified as a means of improving this major setback. To this end, this study is about modeling quality management parameters using lean thinking principles for residential building projects in order to prevent quality management problem as identified in the past. Convenience sampling method was adopted in sample selection in this study. A population size of 250 was used for this project. Data raised in this study includes: primary and secondary data while sample size of 200 was used. The primary data was obtained through the administration of structured questionnaire designed in Likert scale of 1-5 to capture parameters which helped in creating a lean thinking based dynamic model for quality management on sites. 200 questionnaires were administered at random to elicit response from respondents on construction sites in Lagos State. Mean item score was used in analyzing the response from the respondents. The lean principles used to generate the model were further processed with regression analysis using factor analysis to reduce the factors to a sizeable number. The resultant factors were further rotated using factor analysis and direct Oblim method. The factors that had Eigen values between 0.995-1.000 were used to generate the model. It was discovered that some factors emerged with strong coefficient and Eigen values between 0.999-1.000 and these factors were judged as being strong and if one or many of them are combined, there is tendency for them to produce high quality output with zero waste. These factors include: Having maintenance expenditure based on machine/equipment age/utilization; improving construction processes thereby reducing project cost; Management should convey meeting on quality in maintenance issue periodically; and Identifying value from the client’s perspective. In conclusion, from the outcome of the analysis, lean thinking approach is the best approach that would lead to high quality work output and elimination of waste on site, it has tendency to eliminate waste such as time waste, manpower waste, material Lean Concept Thinking-Based Quality Management Model for Residential Building Construction Projects.
