Abstract | This thesis identifies and ranks the most important on-site constraints of precast housing project. A top management survey was conducted to identify the perceptions of project managers of Preuksa firm in relation to construction productivity. Construction labor productivity is of great interest to practitioners and researchers because it affects project cost and time overrun. This work evaluates and ranks the importance, frequency of project delay factors that affect the construction labor productivity for Preuksa village III project. The analysis revealed three most important financial constraints: 1) Strict bank policy on loan, 2) Higher construction materials prices, and 3) Higher fuel prices. The three major productivity loss constraints include: I) Lack of skilled workers, 2) Delays in materials deliveries to site, and 3) Rework (prefabrication error). Comparing the total duration between constraint-free and other constraints, the productivity loss by 8 hours of work day found that in a single unit: lack of skilled workers loss is 0.7 percent, delays in materials deliveries to site loss is 1.6 percent and rework (prefabrication error) loss is 1.0 percent. The results showed that construction productivity loss of total time is small as compared with total cost because Easy Plan program can trade off time and cost. Therefore, the budget is spent more when the duration is reduced. The inferences drawn from this study could be used by the project managers to take account of these factors at an early stage, hence minimizing the time and cost overrun. It is hoped that these findings and recommendations will guide efforts to improve the performance of the prefabricated firms |
