“…For instance, Li et al analyse that significant building structures (like bearing members and their combinations) will likely adopt the cast-in-place way [12]. On the other hand, the secondary-important building member could be precast in the assigned factory, which can be counted in the assembly rate of a building project [13]. During the project lifecycle, it is significant to explore what factors promote and impede the use of prefabrication in construction projects.…”

In recent years, the topic of climate change has been increasingly noticed by the public, and carbon emission reduction is one of the primary targets for various industries worldwide. The construction industry has a profound influence in this field, so it is significant to consider what kind of efforts can be made in building projects. Many scholars agree to promote prefabrication technology for construction, but its application still faces several challenges. By undertaking desk research, this paper explores the motivation and barriers to adopting modular techniques in construction projects under the lifecycle analysis. The preliminary information of the literature review is collated from dozens of peer-reviewed academic papers. Under the whole lifecycle thought, the PEST analysis tools also present the analytical results. This research finds that the top five barriers are the attitudinal resistance to using modular constructions, lack of sufficient modular expertise and practice, increasing costs and risks on supply chain management, insufficient government support and policy making, and high design and planning requirements. Moreover, the lifecycle analysis can divide the collated barriers into each stage, and adequate government support can assist in promoting the prefabrication in building projects in financial, legal, and technical aspects. The current findings can facilitate the broader use of prefabrication in building projects, improving the environmental sustainability of stakeholders. The process of proposed desk research can also be considered a referenced pattern for other related studies. More first-hand data should be collected and evaluated in further research to improve accuracy and adapt to the newest research field and industrial situations.

Under construction industry upgrading and environmental protection requirements, promoting prefabricated buildings is very important, but its development varies significantly in different regions. For example, it only accounts for 20% of the new construction area in China, and the overall development level is low. The promotion of prefabricated buildings involves multiple interests. Then, how to encourage all stakeholders to work together to promote its development is a crucial issue. This study obtains an evolutionary game model among the government, developers, and purchasers. Then the stability strategies of the stakeholders are given conditions. Finally, numerical simulation is used to validate theoretical findings and determine the sensitivity of key parameters to a subject’s behavior. The results show that: (1) There are two key factors that restrict the cooperation of stakeholders to promote prefabricated buildings, including the lack of government subsidies and the weak demand of the purchasers; (2) The government’s overall subsidy should not be too high, exceeding the government’s expenditure on environmental protection, and the subsidies for developers and purchasers must be reasonably allocated to effectively compensate for development benefits and purchase costs under limited expenditures. (3) Improving the residential environment of prefabricated buildings can significantly enhance the vested interests of purchasers, make up for their purchase costs, increase their willingness to purchase, and thus reduce the sales risk of developers.

Evaluation and Optimization of Sustainable Development Level of Construction Industrialization: Case Beijing-Tianjin-Hebei Region

et al. 2022

In order to promote the sustainable development of architectural industrialization, it is necessary to evaluate its development level, identify the development status and key restricting factors, and achieve the effect of “promoting the development by evaluation”. However, the existing studies are mostly limited to the scope of provinces and cities, and there are few studies on the construction industrialization of an economic circle as a whole. Therefore, this paper locates the research within the scope of the region, constructs the evaluation model of the sustainable development level of the regional construction industrialization, and selects the Beijing-Tianjin-Hebei region as a case study. The research shows that the sustainable development level of construction industrialization in the Beijing-Tianjin-Hebei region is in the middle level, which needs to be improved from the aspects of economic support, technological innovation, and management. This paper provides a reasonable reference for how to evaluate and better promote the sustainable development of regional construction industrialization.
