“…At present, the most commonly used prefabricated building materials are block, flat plate, box, and skeleton plate. By analyzing the cost composition of the prefabricated building construction stage, we find it mainly includes planning costs (Zhou et al, 2023), design costs, component manufacturing costs, building installation costs, and later, maintenance costs. This also includes the whole process of prefabricated building construction, and the cost of each stage has different effects.…”

Prefabricated assemblies are popular in the construction industry due to their minimal carbon footprint, enhanced safety, and reliability. A combination of software, including Revit, Navisworks, and Practical Structural Design and Construction (PKPM) software, is used to reduce costs by refining the specifications and dimensions of components, streamlining the variety of molds, enhancing design performance through rigorous component collision inspections and structural optimization, and ensuring cost-effectiveness. The integration of building integration modeling (BIM) visualization significantly diminishes errors attributable to information asymmetry and minimized material wastage stemming from production inaccuracies. The implementation of a Radio Frequency Identification (RFID) information exchange platform enables real-time component tracking, provides insights into the transportation dynamics of these components, and facilitates cost optimization during the transportation phase. Moreover, simulations conducted using Fuzor software preemptively identify potential construction site issues. There is a substantial cost savings of 710,000 yuan.

The assembly efficiency of prefabricated buildings significantly depends on the productive time taken to complete the hoisting operations of components. Therefore, the on-site measurement of the effective time needed for component assembly is crucial for identifying time wastage and improving construction efficiency. This study utilizes MODAPTS (Modular Arrangement of Predetermined Time Standards) and the stopwatch time method to determine the effective working hours of the assembly process. The component hoisting process is broken down into the following five operations, hooking & slinging, hoisting to the operating surface, adjusting the position, removing the load hook, and backing up. A case study of a Nanjing project showed that the average times for five assembly operations of steel components were 227, 279, 760, 160, and 94 seconds. The time variation in crane arm movements is more stable than that of component adjustments during connection operations. Human factors like phone usage, exiting the operation area, along with hoisting point design and production mistakes, greatly reduce hoisting operation efficiency. The results of this study can not only effectively identify the time waste in the assembly process, but also lay a foundation for standardized hoisting operations and calculation of standard working hours in the prefabricated construction industry. In addition, these results will help optimize the construction organization plan at the early decision-making stage and improve the efficiency of resource use, thus shortening the construction period and reducing the construction cost.

PurposePrefabricated construction (PC) can benefit construction industry due to its high efficiency, energy saving, consumption reduction and safety. However, the high capital cost is a critical challenge hindering its development in China. The collaboration of PC stakeholders is conducive to improving cost management efficiency and optimizing resource allocation which has been ignored in previous studies. Therefore, this study aims to explore the collaboration paths of stakeholders in the process of solving critical cost influencing factors (CIFs) of PC to reduce costs.Design/methodology/approachFirstly, 25 CIFs and five main stakeholders that affect PC capital cost were identified through literature research and expert interviews. Then, questionnaires were used to investigate the relationship between stakeholders and CIFs from the perspectives of three stakeholder attributes of proximity, attitude and power, respectively. Finally, based on the survey data, three stakeholder-CIF networks from three attributes perspective and a comprehensive network were constructed and used for subsequent social network analysis.Findings(1) Stakeholders mainly show willingness and potential to collaborate on organization and management factors; (2) More stakeholders pay attention to incentive policies and the setting of prefabrication rates and assembly rates, while all stakeholders have the right to facilitate information and resource sharing in the PC supply chain; (3) The comprehensive network shows a core-periphery structure. As core stakeholders, contractor, designer and manufacturer are more likely to actively manage the 14 core CIFs.Originality/valueThis paper innovatively combined stakeholder and cost management in PC, and used two-mode network based on three stakeholder perspectives to reveal the collaboration potential and motivation of stakeholders in PC cost management. The findings not only provide guidance for stakeholders to find potential partners and optimize resource allocation in solving specific cost issues, but also facilitate stakeholders' sustainable collaboration to achieve PC's cost performance.
