“…There is a need for more detailed and effective cooperation in all stages of a prefabricated building including design, procurement, prefabrication, transportation, on-site assembly, construction, installation, declaration, and operation. Component transportation from the factory to the site is also a critical problem affecting the supply chain integration [32]. Arditi et al and Polat investigated factors affecting the use of prefabricated concrete systems in 1995 and 2008, respectively, in the U.S.…”

“…The designer must consider the specific modules and component constitutions as well as their precise assembly [39]. Complex modules need more design work because they produce more subsequent prefabrication work, transportation work, assembly work, and coordination work [32]. A good design can enhance the value of the building while an incompetent design may lead to poor construction quality (e.g., cracks, leakage, joint failure) [34].…”

Prefabricated construction has been proven effective, environmentally-friendly, and labor-friendly. It is widely considered a sustainable approach to the construction industry. China is still in the initial process of adopting prefabricated construction practices and has conducted a few studies to date on the constraints of prefabricated construction up to the operation stage. This paper focuses on the major factors obstructing prefabricated construction development in China. Twenty-three variables affecting said development are summarized per the results of a literature review and a semi-structured interview. A questionnaire was delivered to developers, designers, contractors, engineers, component suppliers, and property managers. A total of 160 valid respondents were collected. Twenty-three variables were ranked by the mean score after an Analysis of Variance (ANOVA) indicated that no statistical differences in the data from six stakeholders. Principal Component Analysis (PCA) was employed to reduce the dimensionality of four factors: industry chain, cost, social climate and public opinion, and risk. The risk is found to be the main influencing factor even though it is rarely the focal point of research on prefabricated construction. The findings presented in this paper may assist different stakeholders in better understanding issues with prefabricated construction practices in China at present and, therefore, find workable solutions.

“…Nevertheless, the construction of IB has modified the situation. Most of the work is not performed on site (because of factorial prefabrication [65], on-site construction has considerably declined [21]), mechanization is used for reducing risk and intensifying labor [66], and atmospheric conditions at the construction site are enhanced; therefore, the safety and health of employees are guaranteed [67] and the chances of accidents are declined [25]. …”

Compared with the conventional building, the industrialized building (IB) promotes the sustainable development of the construction industry, which will become a growth trend in the future. Nevertheless, the progress of industrialized building is intimately affected through the scientific evaluating mechanism, which still requires more research. Thus, this study establishes a conceptual framework of industrialized building assessment (IBA), which is validated through exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The impact between efficiency and the other five dimensions are studied by the structural equations model (SEM). The findings indicated that the conceptual framework is valid, and the efficiency has a positive impact on economic factors, livability, safety, environmental factors, and social benefits. Consequently, the improvement of efficiency has turned out to be the primary issue for improving the growth of the industrialized building. This research explores the basic framework of industrialized building assessment and provides a basis to establish a comprehensive and precise industrial building evaluation mechanism in the near future.

“…The sustainability practices identified are: (1) prefabrication, preassembly, modularization, and offsite construction (PPMOF) evaluation [20,[43][44][45]48,49,52,54,56,57]; (2) startup processes and systems [20,42,46,47]; (3) meeting startup quality [20,42,46,47]; (4) community relations [15,20,[58][59][60][61][62]; (5) life cycle cost analysis [20,32,36,48,50,57,61,63]; (6) regulatory requirement, permitting, and environment [15,20,35,60,61,[64][65][66]; and (7) sustainability [20,35,64,66]. The description and sources of sustainability practices from the literature review are summarized in Table 1.…”

“…The PPMOF has multiple sustainable impacts for construction: (1) improve productivity and reduce cost (economic); (2) improve workers' safety at the construction site (social); and (3) control and reduce environmental impacts (environmental) [20,[43][44][45]48,49,52,54,56,57]. Therefore, the evaluation of the PPMOF practice is usually implemented in the front-end planning phase, and associated with all three sustainability dimensions: environmental, social, and economic.…”

Despite the efforts for sustainability studies in building and infrastructure construction, the sustainability issues in industrial construction remain understudied. Further, few studies evaluate sustainability and benchmark sustainability issues in industrial construction from a management perspective. This study presents a phase-based benchmarking framework for evaluating sustainability practices use focusing on industrial facilities project. Based on the framework, this study quantifies and assesses sustainability practices use, and further sorts the results by project phase and major project characteristics, including project type, project nature, and project delivery method. The results show that sustainability practices were implemented higher in the construction and startup phases relative to other phases, with a very broad range. An assessment by project type and project nature showed significant differences in sustainability practices use, but no significant difference in practices use by project delivery method. This study contributes to providing a benchmarking method for sustainability practices in industrial facilities projects at the project phase level. This study also discusses and provides an application of phase-based benchmarking for sustainability in industrial construction.
