Conceptual Model of Critical Factors Affecting Performance of Construction Sites in Vietnam

With the economic development, Vietnamese construction industry also progresses at a brisk pace and accounts for major factor of economy. Therefore, it is necessary to make the industry more efficient and effective in terms of better utilization of resources. Part of the most important resources include materials, time and cost. However, there are many problems such as wastes and losses of resources, cost overrun, time delay, and low quality, which lead to reduce the performance of construction site, need to be addressed. The objective of the study outlined in this paper is to construct a conceptual model of critical factors affecting performance of construction sites in Vietnam; the performance of construction sites is defined under form of cost and time. A survey was carried out and found out 25 key factors that influence on the performance of construction sites. The factor analysis revealed that these factors could be grouped into six major factors, namely, (1) management, (2) human resources, (3) technology, (4) finance, (5) material/equipment, and (6) design. Finally, multiple linear regression was applied to identify level of influence of each factor group on the performance of construction sites. Th
