“…The experienced practitioners paid more attention to the practical factors in design, production [62], transport, and installation processes. However, the inexperienced ones took the potential risks and expenses into account when they chose the prefabrication [1]. For the experienced ones, the government can take measures to solve practical problems, such as technical innovation and management mode.…”

Abstract:As a sustainable construction method, prefabrication has become popular in many nations. However, there are many challenges for prefabrication, especially in terms of cost. Previous studies have revealed that higher capital cost was the most important barrier to the implementation of prefabrication. Thus, the objective of this study is to explore and evaluate the critical factors affecting the capital cost of prefabrication and examine how cost management may be affected by the "experience", "corporate responsibility", and "participant function" as a fix independent factors. To achieve the research objective, semi-structured interviews were conducted with 11 experts for the development of the questionnaire. Then, a questionnaire survey was conducted to investigate the significance of 49 factors related to prefabrication capital cost. The survey results revealed that "Specification and standards for prefabricated building design", "Related experience of manager", and "Rationality of precast component split" were the most critical factors. In addition, "experience", "corporate responsibility", and "participant function" had significant impact on the evaluation of capital cost factors. The findings can facilitate developing a benchmark framework for exploring the factors affecting the capital cost of prefabrication in China.

“…The module manufacturing activities that take place in the factory are stochastic and dynamic in nature and changes within activities occur as a variable of time [59], hence the decision to utilize a BIM based 4D simulation model for this research. Computer based modeling is widely used for the simulation and analysis of economic problems and is known to be an efficient tool for the optimization of project productivity, represented here in terms of the schedule, and the quantity and quality of the output [60,61].…”

“…In the context of project management, a project management tool based on 4D simulation is an effective and popular method which facilitates the exploration, description and interpretation of the processes and behaviors involved in construction projects. [59] There is clearly a need for both short-term management (of the order of an hour or a shift) that can resolve problems quickly and accurately by measuring task procedures and resource quantities and then producing modules suitable for short processes, as well as long-term management (that might depend, for example, on the day of the week [19]) that provides the parametric information required to achieve goals related to the module manufacturing schedule, material quantity, and quality [62].…”

Modular construction methods, where products are manufactured beforehand in a factory and then transported to the site for installation, are becoming increasingly popular for construction projects in many countries as this method facilitates the use of the advanced technologies that support sustainability in building projects. This approach requires dual factory-site process management to be carefully coordinated and the factory module manufacturing process must therefore be managed in a detailed and quantitative manner. However, currently, the limited algorithms available to support this process are based on mathematical methodologies that do not consider the complex mix of equipment, factories, personnel, and materials involved. This paper presents three new building information modeling-based 4D simulation frameworks to manage the three elements-process, quantity, and quality-that determine the productivity of factory module manufacturing. These frameworks leverage the advantages of 4D simulation and provide more precise information than existing conventional documents. By utilizing a 4D model that facilitates the visualization of a wide range of data variables, manufacturers can plan the module manufacturing process in detail and fully understand the material, equipment, and workflow needed to accomplish the manufacturing tasks. Managers can also access information about material quantities for each process and use this information for earned value management, warehousing/storage, fabrication, and assembly planning. By having a 4D view that connects 2D drawing models, manufacturing errors and rework can be minimized and problems such as construction delays, quality lapses, and cost overruns vastly reduced.
