“…Similar studies have been conducted by Isaac, Curreli [33] and Niu, Lu [34]. Mostafa, Kim [35] also emphasized that BIM can effectively minimize the communication-specific issues for prefabrication practice. If the lack of installation planning cannot be timely addressed, they will prevent the crane efficiency from transporting the prefabricated products (from lift point to the place point) in a JIT manner.…”

Although prefabrication housing production (PHP) has been widely advocated with advantages like ensured good quality and secured workplaces, its poor interoperability and fragmentation still causes various constraints, limiting the progress of projects. This paper aims to model the constraints and their relationships in task executions of different trades during the on-site assembly process of PHP. It was conducted through a typical PHP case study in Hong Kong to identify the critical trade associated constraints and their links during the on-site assembly process. Original data were collected by semi-structured interview, Delphi survey and questionnaire with representative professionals from the case. Social Network Analysis (SNA) was used to model the constraints and their interrelationships. The results indicated that seven trade-associated constraints were worth more attention. Three significant challenges were determined, indicating that the on-site team should focus on the availability of labor resources, optimal installation planning and effectiveness of communication mechanism. Smart work packaging (SWP)-enabled system for achieving automatic constraint identification and dynamic constraint relationship mapping under different constraint scenarios was suggested. This paper offers practical insights for scholars to conduct a trade-associated constraint identification study in the network manner and is expected to benefit practitioners on using the results for decision-making.

“…Where lij is the load of the original variable on each principal component, and the new variable indexes q1, q2... Are called the first, second,... principal components of the original variable index respectively, and q1 and q2 are independent of each other. The essence of principal component analysis is to determine the load lm of the original variable x1 on each principal component q1, which are the eigenvectors corresponding to the m larger eigenvalues λi of the correlation matrix, and standardize the data samples as follows: (6) Where:…”

The primary goal of material management is to reasonably arrange the use of materials, which is particularly important for the construction industry. In the process of material management, on the premise of meeting the requirements of production and construction materials, try not to increase additional inventory and reduce the amount of capital. In order to explore the method of prefabricated building material management, this paper uses the method of sampling survey and sand table simulation technology to compare the prefabricated building material management based on BIM Technology with the conventional method. We make a comparative study on the procurement, warehouse and material quality of materials, mainly focusing on the production stage and construction stage of the building, and analyze the difference of material management between the two technical methods in different stages. Through experiments, we find that the average inventory turnover times of the BIM based prefabricated building materials management method is 6, and that of the conventional method is 4, but in the construction stage, the gap between the two is narrowed. The turnover times of the prefabricated building material management method based on BIM Technology is reduced to 3, and that of the conventional method is reduced to 2. It can be seen that the prefabricated building material management based on BIM Technology can reduce the capital use and warehouse occupancy rate more than the conventional method, and at the same time, the quality control of materials is also better.

“…These include: lack of uniqueness or customization in prefabricated building design and poor consideration of geological conditions [33]. To enhance the constructability, it is necessary to use information technologies such as Radio-frequency identification (RFID) and Building Information Modelling (BIM) [34,35]. This will help to clearly understand the information flow associated with the entire process and assist the material selection.…”

“…In terms of performance, the following risks are less managed: It is interesting to note that although most of the top ten risks are located in early project stages (e.g., feasibility study stage and design stage), it is reported by survey respondents that performance of risk management is comparatively poorer in later project stages (e.g., manufacturing stage and construction stage). Indeed, a number of risks exist in the factory environment during the manufacturing stage as well as transporting prefabricated components to the construction site for assembly [35]. The vast majority of these risks are technical issues during the manufacturing stage and the construction stage.…”

Risks in Prefabricated Buildings in China: Importance-Performance Analysis Approach

2019

View full text Add to dashboard Cite

Prefabrication has drawn wide attention in China during the last decade. However, the market share of prefabricated buildings in China remains comparatively low. The Importance-Performance Analysis approach is employed in this study to investigate the crucial risk factors associated with prefabricated buildings in China. A preliminary list of risks associated with prefabricated buildings in China was developed based on a critical literature review, which was consequently refined by the interview with related experts. A questionnaire survey was then conducted with selected industry professionals to solicit their expert opinions of critical risks associated with prefabricated buildings in China. Findings show that attention should be paid to the following risks: improper decomposition system, low level of factory management, incompetent quality assurance system, deviation in specification of prefabricated components, defects of component system, missing catalogue of building parts and components, poor adaptability of prefabricated building during the operational stage, and lack of actual cases to prove the environmental benefits of prefabricated buildings. This study also revealed the discrepancy between perceived critical risks and those risks with comparatively lower management performance. These findings offer useful inputs for the future development of prefabricated buildings in China and beyond.
