“…The significance of the LPS and BIM is widely acknowledged in addressing the shortcomings of production planning and control [31,33,45]; however, the current policies lack validation. Accordingly, this paper assesses the stakeholders' expectations about LPS and BIM for MD mitigation strategies through a literature review, thematic analysis, and a qualitative data analysis technique (as listed in Figure 2).…”

“…The MD is located in the heart of the CLD, as shown in Figure 9, and has a critical impact on driving the B1 loop; MD depends on the number of constraints encountered and removed in the system [45]. The qualitative model was expanded to accommodate the changes in MD, constraints, and waste caused by MD initiated by schedule pressure.…”

“…Consequently, the mentioned system parameters and casualties were developed using a literature review. The impact of strategies from LPS Functions and BIM functionalities parameters on mitigating MD [24,31,33,45] are hypothesized in the CLD by affecting constraints discovery rate, reducing schedule pressure, and improving resource allocation and utilization. Although the strategies and casualties may differ based on the project and company contexts, this paper aims to demonstrate the influence of SDM on optimizing production planning and control by reducing the number of tasks infected with MD practices through LPS and BIM.…”

Effective waste elimination is critical for the success of construction projects. Although several studies have focused on various aspects of construction waste, limited efforts have investigated the dynamic effect of Making-Do (MD) practices on productivity, rework, defects, and materials wastage. From a lean construction perspective, this study aims to address MD waste using the Last Planner System (LPS) and BIM. First, the casual structure that can cause MD in construction projects was expressed in a casual loop diagram (CLD), and thematic analysis uncovered the strategies of LPS-BIM to eliminate MD identified by reviewing the literature. Secondly, twenty-five strategies from the LPS and BIM strategies to address MD using Structural Equation Modeling (SEM) were assessed. Subsequently, a system dynamics model (SDM) for investigating LPS-BIM strategies on MD decisions in a construction project was formulated based on the underlying causal loop diagrams and the mathematical relations among the variables. Finally, the model was applied to three projects, and simulations for four LPS-BIM scenarios were carried out. The findings show that dynamic interactions among diverse production planning and control factors are critical in evaluating MD impacts on a construction project. The results demonstrate that the LPS-BIM approach resulted in an average 43.8% reduction in the tasks performed with MD, 45.3% of constraints, 66.5% of construction waste, increasing 13.7% completion rate, and 29.3% cost reduction, demonstrating that LPS-BIM as a more efficient solution for MD mitigation and construction planning.
