Abstract
Emerging construction practices such as building information modelling (BIM), prefabrication construction, green building, and integrated project delivery methods are gaining momentum in China, with great potential due to the size of its construction market. Through this, the sustainability level of China’s construction industry is expected to be enhanced from the economic, social and environmental perspectives. So far, there has been limited understanding of how BIM, as a digital technology, would affect other contemporary sustainable construction practices from the industry professionals’ point of view. Limited studies have been carried out to study the regional differences of these contemporary sustainable practices in China. This study adopted a questionnaire-based approach targeting industry professionals from three different metropolitan cities (Shanghai, Guangzhou, and Wenzhou).The follow-up comprehensive statistical analysis revealed that with regards to these contemporary sustainable construction practices, survey participants held much varied views on the growth of renovation projects, traditional Design–Bid–Build delivery, and conventional on-site construction methods. These three types were also generally perceived to have weak correlation with BIM application. Regional comparison further conveyed information on differences in perceptions among survey respondents from these three cities. For example, respondents from Wenzhou perceived more positive effects of BIM use in conventional construction projects. This research addressed the inter-correlation among these emerging sustainable construction practices, as well as the regional differences in China’s construction market. The findings provide insights and the big picture for both governmental authorities and industry practitioners on the latest sustainable practices of China’s construction industry. Recommendations are also offered towards improved economic, social and environmental sustainability performance for construction projects in the country.
Highlights
Some new practices, such as building information modeling (BIM), prefabrication construction, green building, and integrated project delivery methods are more emphasized in the construction industry across the globe and China is no exception [1]
Five contemporary practices were believed to grow at a high rate, namely DB projects, prefabrication construction, projects with building information modelling (BIM) application, green building, and private partnership (PPP) projects
As an extension of the finding from the first question regarding the movement of different types of projects, Wenzhou participants perceived a higher positive impact of BIM on conventional construction. This comparative study adopted Shanghai, Guangzhou, and Wenzhou as case studies to reflect the current stage of construction industry sustainable practices (i.e., BIM, prefabrication construction, green building, and integrated project delivery) in China
Summary
Some new practices, such as building information modeling (BIM), prefabrication construction, green building, and integrated project delivery methods are more emphasized in the construction industry across the globe and China is no exception [1]. These practices are proposed to enhance the overall sustainability of China’s construction industry. Their developments in different provinces/cities in China are, unbalanced. As indicated by Jin et al [2], China has its own regional differences in BIM practice due to its large geographical spread. Regional disparity exists regarding the development of green building in China—while a total of 487 projects with the green building label are delivering or have been delivered in Jiangsu province, the number of sustainable projects in the Xinjiang Uygur Autonomous Region is only seven up to now [4,5,6]
