“…This paper studies the basic aspects and classifications of building assessment. At present, there are few IBAs, and most assessments are concerned with safety and health [1,67], environmental impact [9,28], economical effect, and social benefit [26,30]. However, in addition to the above contents, rational IBA still requires the dimensions of efficiency and livability [33,42].…”

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.

“…This included items that directly impacted the economic performance of prefabricated construction. In a case study on eight buildings under a cost-benefit analysis framework, the cost intensity of prefabricated buildings was proven to be 26.3% to 72.1% higher than conventional buildings with a significant positive correlation to the prefabrication rate [29]. Mao et al conducted a questionnaire survey in China to find barriers to off-site construction from the developer's perspective.…”

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.

“…The impact of prefabrication is a debated topic. For example, Hong et al (2018) discuss the impact of prefabrication on construction project costs. Prefabrication is argued to lower the project costs due to faster project delivery, cheaper labour rates, minimal waste, and the avoidance of construction site hindrances.…”

Several academic and industrial studies have documented the benefits of prefabrication compared to on-site construction. However, key construction project actors find it difficult to analyse whether prefabrication would be beneficial for their project with specific circumstances and targets. This research aims to develop a process to evaluate the impact of prefabrication in projects. First, based on the literature review and focus group discussion, we define the impact factors of prefabrication. Second, we apply Choosing by Advantage (CBA) approach together with Cost-Benefit-analysis to define a process for prefabrication impact measurement which considers various impact factors and their importance in the project. Finally, we validate the process with the industry experts. The paper contributes to knowledge on robust decision-making processes about production methods in situations in which all impact factors are not easily comparable but require a subjective valuation.
