“…Articles without authors related to prefabricated/off-site building construction were removed. They were constructed under a controlled nature, procuring bulk of materials, using different technology and special skills required [36]. Therefore, acquisition costs differed from the inflation's effect on acquisition costs, which differs from on-site construction.…”

The global GDP has witnessed a significant upswing, majorly due to the growth of the construction industry. Embracing the whole-life costing (WLC) approach, the construction sector strategically manages expenses across a construction project’s life cycle. However, despite its widespread adoption, accurate cost forecasting remains a major challenge. The intricate interplay of various influencing factors has not been fully explored, leading to inaccurate cost estimations. A comprehensive understanding of specific factors and their interrelationships is crucial to address this issue. Therefore, it is imperative to conduct further research to identify and explore the subtle nuances of these factors that impact whole-life cost estimation. Our study fills this gap, analysing 51 factors from 84 papers across prominent repositories. We assess interrelationships using a systematic literature review and pairwise comparison as in the analytical hierarchy process. The International Construction Measurement Standards (ICMS) framework structures these relationships and is represented in the causal loop diagrams (CLDs). The pioneering CLDs are a notable contribution, illustrating interrelationships and polarities among the 51 WLC factors. Six reinforcing loops and one balancing loop provide valuable insights into their dynamic nature. Importantly, lower-level factors do not always directly connect with upper-level factors. Instead, they interact within the same level before linking to top-level factors. These findings are significant for professionals, such as cost estimators, quantity surveyors and scholars, offering a comprehensive understanding of the WLC system.

Nowadays, providing housing for the low-income groups of society is a concern for governments, especially in developing nations. An attempt has been made to recognize the most significant real criteria for reducing housing project costs and providing affordable housing for them by studying previous research and analyzing the collected information. First, the resources compiled in the field of affordable housing were reviewed, and data were gathered. Next, qualitative and quantitative questionnaires were provided, and the experts’ answers were analyzed in three steps (Delphi technique, AHP techniques, and case studies). By analyzing the findings, it was concluded that the current approaches in housing planning need to be revised to achieve the government’s goals and policies. Therefore, the physical indicators and patterns of vernacular and traditional houses in different climatic regions should be known and changed in the next step according to the needs of the modern world. The adaptation of today’s architecture from the vernacular architectural features of the past is one of the important things that should be considered. In this research, the consideration of housing preparation for low-income groups and reducing housing project costs, by identifying the most important effective criteria mentioned in other previous studies, is the novel contribution of this research.

“…At the same time, developers, as prominent participants in developing prefabricated buildings, have also received much attention. Based on online research, Rotimi found that the obstacles to developing prefabricated buildings are closely related to the professional skills shortage of relevant management, design, and residential construction practitioners [ 35 ]. Lee compared and analyzed the implementation conditions of modular buildings based on actual development cases and concluded that the construction cost was high [ 36 ].…”

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.
