“…The top five critical wastes are discussed. Reworks/abortive works (W03) obtained the highest criticality (mean = 3.60) to productivity performance, indicating that building projects in Singapore suffered from numerous abortive works [40]. This result echoed the post-survey interviewees who reported that abortive works occurred throughout the construction phase and influenced many trades on site.…”

Building information modeling (BIM) is deemed a useful innovation for technological and sustainable development of the economy. It is partially used in building projects in Singapore, although its implementation is mandated by the local government, resulting in various wastes and suboptimal productivity. Little is known about how non-value adding (NVA) BIM implementation practices were perceived by the local practitioners and how these practices affected productivity in building projects in Singapore. This study aimed to identify critical NVA BIM implementation activities and investigate the criticality of their resulting wastes to productivity performance in the current project delivery process in Singapore. The results from a questionnaire survey of 73 experts and four post-survey interviews in Singapore revealed that 38 NVA BIM implementation activities were deemed critical, among which “lack of involvement by contractors to contribute site knowledge” in the design development phase was ranked top; the top five resulting wastes with highest criticalities were reworks/abortive works, requests for information, design deficiencies, defects, and waiting/idle time. Furthermore, an independent-samples t-test was conducted to examine whether construction firms and upfront stakeholders perceived the NVA activities differently. It was discovered that most NVA activities exerted more agreement from construction firms than upfront non-construction organizations. Six strategies were proposed to mitigate the NVA activities and wastes. The findings can help practitioners identify weak areas of their BIM implementation practices and prioritize resources accordingly to eliminate the wastes and foster sustainability, as well as help overseas project teams, with minor adjustments, customize their own NVA BIM implementation activities and management strategies.

“…Regarding research conducted in Singapore, Oo [22] identified critical cultural and individual factors for the architectural firms in Singapore to move from the traditional work practices, but did not identify the factors motivating collaborative relationships among the primary participants. Hwang et al [23] found that BIM implementation had a significant impact on reducing reworks arising from various changes and errors/omissions in building projects in Singapore, but did not indicate how to promote BIM diffusion. Moreover, little was known about how the driving factors may influence different organizations' BIM implementation.…”

“…Thus, the sample had a good balance of stakeholders and represented major BIM implementers in Singapore. To gain an in-depth understanding of the factors' influence on different types of firms, face-to-face interviews were conducted with industry experts [23,54]. This mixed method reduced the bias originating from a single source of data and facilitated a comprehensive understanding of the factors [55].…”

Diffusion of Building Information Modeling in Building Projects and Firms in Singapore

Building information modeling (BIM) implementation has been mandated in building projects in Singapore, but a wider adoption is still desired. This study aims to investigate the factors influencing BIM diffusion and examine how the factors influence firms with different project roles, firm sizes, and BIM implementation experience. The results of a pilot study, a questionnaire survey with 89 professionals, and five post-survey interviews showed that hindrances related to inadequate multi-party collaboration (whether formal or informal), conservative mindset, limited skills, costly infrastructure and training, and multi-discipline model integration were the most influential, whereas drivers associated with project leadership team’s strategic consensus, multi-disciplinary design coordination, training, and government regulations were top-ranked. Subgroup analyses between pairs of firms with different characteristics revealed that while construction firms and less experienced stakeholders tended to underestimate BIM implementation difficulties, small-medium contractors might underestimate relevant benefits. The findings and managerial recommendations help different types of firms prioritize resources to overcome hindrances, seize opportunities (such as gaining a competitive edge from BIM practical experience), and obtain support from workers executing BIM daily. With major stakeholders’ recognition and implementation, BIM can be successfully diffused in building projects and firms. The Singapore government and other countries can refer to this study when further issuing BIM diffusion policies.

“…The efficient combination of BIM and the design phase can help designers achieve multiple goals. In the design phase, BIM can effectively avoid rework problems caused by design errors and improve the delivery rate of the project [19]. At the same time, BIM can also be used as a collaborative design platform for information sharing to solve the interoperability of design software data of different disciplines problem for achieving real collaborative design [20].…”

Building Information Modeling (BIM) technology has promoted the development of the architecture, engineering, and construction (AEC) industry, but has encountered many barriers to its application in China. Therefore, identifying the barriers to BIM application and capturing their interactions are essential in order to control and eliminate the determined barriers. From this standpoint, 23 BIM application barriers were identified through a literature review and expert interviews. Furthermore, the interactions among them were determined based on the Delphi method, which was the foundation for establishing the BIM application barrier network (BABN). Then, the software Pajek was employed to construct the network model and reveal its topological characteristics based on complex network theory, including degree, betweenness, eigenvector, clustering coefficient, network diameter, and average path length. As indicated by the results, BABN possesses scale-free network property because its cumulative degree distribution obeys power-law distribution. BABN is also a small-world network, due to its relatively high clustering coefficient as well as small average path length, implying that barrier propagation in BABN is fast. In addition, the results are discussed and recommendations are proposed. This research will help BIM stakeholders to develop coping strategies to control and eliminate BIM application barriers for the sake of driving BIM sustainable development.Sustainability 2020, 12, 3190 2 of 22 showed that applying BIM can reduce errors in the project, which reduces the cost compared to the up-front cost brought by applying BIM. As a digital technology, BIM can reduce cost throughout the building's lifecycle [5]. It can be utilized to support design, procurement, fabrication, construction, operation, and maintenance, such as cost management, time management, risk management, resource management, facility management, and sustainable applications. In short, BIM offers the potential to help transform the construction industry and boost productivity in the AEC industry [6].As the application of BIM helps to promote the sustainable development of the AEC industry, many governments are actively promulgating policies to accelerate the process of BIM adoption, including the United States, China, the United Kingdom, Singapore, and others [7]. The government has been an active advocate of BIM application. The Chinese AEC industry is one of the biggest and most important markets in the world, and it also plays a pivotal role in China's economy. Recently, the Chinese government has been actively promoting the development of BIM technology in China. The study conducted by Lin and Zhang [8] indicated that China's national government, local government, and association issued a total of 58 BIM-related policies from December 2013 to December 2017, and the number of polices demonstrated a typical exponential growth trend. It can be inferred that the relevant state agencies will increasingly be issued along with the development of BIM.Co...
