“…A Likert scale served as the evaluation set in many previous studies [50,51]. Hence, it was adopted here to measure the severity of each design barrier: 1, 2, 3, 4, and 5 represent very weak, weak, medium, strong, and very strong, respectively [52]. The calculation principle is shown in Equations (5) and (6).…”

As a sustainable and cleaner type of facility, prefabricated buildings face more design barriers than traditional non-prefabricated buildings. Identifying and managing these barriers is key to improving the success rate of prefabricated building design. However, direct studies on these design barriers are extremely rare. The present study solved this problem by combining multiple methods, including grounded theory (GT), structured self-intersection matrix (SSIM), analytic network process (ANP), and the linear weighted sum method (LWSM). GT was adopted to identify the barriers to prefabricated building design and then SSIM was used to analyze the interactions among them. The eight design barriers were finally identified and classified into three clusters: technical barriers, economic barriers, and management barriers. A further analysis found that there is dependence and feedback among these clusters. The technical barrier cluster and management barrier cluster experience self-feedback. A network model based on ANP was next established to calculate the weights of the barrier elements and then this model was combined with LWSM to evaluate the overall design barrier strength of a project case. The results showed that architectural individualization has the greatest impact on prefabricated building design, followed by the collaborative issues among multiple units and professional designer issues. The overall design barrier strength of the project case was larger. Therefore, the first suggestion provided to the facility management sector is to establish a library for standard house types to achieve architectural design through multihouse combinations.Sustainability 2020, 12, 2994 2 of 16 construction [7], and off-site construction [8]. Whether emergency-driven or market-driven, prefabricated buildings are becoming increasingly popular. However, several barriers affecting the development of prefabricated buildings are often mentioned, including a higher total cost [9], impaired aesthetics [10], additional risks [11], a lack of professional expertise [12], and the absence of management experience [13]. Nevertheless, prefabricated buildings are still favored by the government of China due to their many advantages, including their faster construction speed [14], less required on-site labor [15], higher construction quality [16], sustainable development [17], and superior occupational health and safety [18]. With the development of prefabricated buildings, some new issues are beginning to emerge and become increasingly prominent, especially the design changes of prefabricated buildings. Bogenstatter noted that the design stage determines up to 80% of operational costs, as well as the environment impacts [19,20]. Hence, design changes can waste a great deal of time and money and even affect the quality of buildings. Overcoming this issue remains a troubling prospect for industry insiders and researchers.Design changes are common not just for ordinary buildings but also for prefabricated buildings. However, the design of a p...

Deciding whether bid for the construction project is classic risk-based decision-making that is crucial to the survival and prosperousness of construction companies. More contractors are adopting group bidding decision-making to reduce the number of incorrect decisions. However, previous related studies mainly focus on project factors that overlook the members of bidding groups and the interaction between bidding group members. e aim of this paper, therefore, is to investigate the potential factors that influence group bidding decision-making for construction projects. Twenty factors relating to individual, group, and organizational levels are identified through a literature review and interviews with experienced practitioners. A questionnaire survey of 203 Chinese international contractors is conducted to obtain the importance of the factors involved. e results of the ranking analysis indicate 14 critical factors, among which "risk perception" and "team decision preference" are regarded as the two most significant. Moreover, 20 factors can be classified into five groupings: (1) values and strategic goals, (2) collaboration and learning orientation, (3) consensus reaching, (4) risk awareness, and (5) empowerment and development, with risk awareness having an especially strong influence. is research deepens the understanding of factors belonging to different organizational levels that need to be highlighted during the group bidding decision-making process and provides strategies for bidding groups and their companies to improve their decision performance.

“…The key success factor affecting the use of the turnkey method on school construction projects is the need to have proper system planning [10,14,16]. After organizing the interviews conducted with experts and organizing directors, the following items should be noted when the school has decided to use the turnkey method: Pre-process:…”

Abstract. This research began with the status of the implementation of school construction projects to explore the relationship between the characteristics of its management and its impact on different levels. Through gathering literature, interviewing experts, statistical methods, and other methods of analysis, ways to improve the tender process were understood. Organizing the domestic and international literature gathered, understanding similar domestic systems, and other cases helped to develop guidelines for the shift of school construction projects into the turnkey method. The selection of appropriate vendors will reduce the likelihood of disputes arising due to compliance issues as well as address project delays and quality issues. This research began by analyzing the causes of the current issues experienced in the universities whose cases were gathered. It was proposed that the proper improvement strategy be the integration of the turnkey method into the construction projects of the schools. It was discovered in the results that using the turnkey method for school construction projects will result in 20% savings in time and cost. In addition, it was proposed that the establishment of an improved system will facilitate the smooth completion of projects; the turnkey method should be implemented on three major levels including the pre-process, selection of a turnkey vendor, and prudent planning during the implementation stage (compliance management).
