“…The main highlight is that in each case, a considerable reduction in the part count has been achieved, resulting in a simpler product (Boothroyd, 1994). In construction, Chen and Lu (2018) noted, much less research has provided empirical evidence of the effects of DfMA in construction, with the exception of several examples that applied DfMA principles to various types of facilities and found benefits that were qualitative in nature, such as reducing material most, minimizing assembly and transport cost, etc. However, from a holistic perspective, the overall cost intensity is the main cause of the slow uptake of DfMA.…”

Design for Manufacture and Assembly (DfMA) is known as both a philosophy and a methodology whereby products are designed in a way that is as amenable as possible for downstream manufacturing and assembly. As construction is moving towards a combination of offsite prefabrication and onsite assembly, DfMA is gaining momentum in this heterogeneous industry. Nevertheless, a comprehensive review of DfMA in construction, its prospects and challenges in particular, seems absent from the literature. This study reviews the processes and principles of DfMA and explores the possible perspectives of DfMA with a view to providing implications to the construction industry. It was found that DfMA in construction has been interpreted from three perspectives: (1) a holistic design process that encompasses how structure or object will be manufactured, assembled and guided with DfMA principles; (2) an evaluation system that can work with virtual design and construction (VDC) to evaluate the efficiency of manufacturing and assembly; and (3) a game-changing philosophy that embraces the ever-changing prefabrication and modular construction technologies. This study suggests that development of design guidelines, forming multidisciplinary team, use of VDC systems and understanding the lean principles are factors that could further enhance the successful application of DfMA in construction.

“…The design unit needs more assistance from the manufacturing unit and the construction unit when it carries out the design of a prefabricated building. Design for manufacture and assembly (DFMA) is a tool for improving prefabricated design [21][22][23]. DFMA is a lean principle and advocates that the design of a unit should consider the requirements of other units during the prefabricated building design.…”

As a sustainable and cleaner type of facility, prefabricated buildings face more design barriers than traditional non-prefabricated buildings. Identifying and managing these barriers is key to improving the success rate of prefabricated building design. However, direct studies on these design barriers are extremely rare. The present study solved this problem by combining multiple methods, including grounded theory (GT), structured self-intersection matrix (SSIM), analytic network process (ANP), and the linear weighted sum method (LWSM). GT was adopted to identify the barriers to prefabricated building design and then SSIM was used to analyze the interactions among them. The eight design barriers were finally identified and classified into three clusters: technical barriers, economic barriers, and management barriers. A further analysis found that there is dependence and feedback among these clusters. The technical barrier cluster and management barrier cluster experience self-feedback. A network model based on ANP was next established to calculate the weights of the barrier elements and then this model was combined with LWSM to evaluate the overall design barrier strength of a project case. The results showed that architectural individualization has the greatest impact on prefabricated building design, followed by the collaborative issues among multiple units and professional designer issues. The overall design barrier strength of the project case was larger. Therefore, the first suggestion provided to the facility management sector is to establish a library for standard house types to achieve architectural design through multihouse combinations.Sustainability 2020, 12, 2994 2 of 16 construction [7], and off-site construction [8]. Whether emergency-driven or market-driven, prefabricated buildings are becoming increasingly popular. However, several barriers affecting the development of prefabricated buildings are often mentioned, including a higher total cost [9], impaired aesthetics [10], additional risks [11], a lack of professional expertise [12], and the absence of management experience [13]. Nevertheless, prefabricated buildings are still favored by the government of China due to their many advantages, including their faster construction speed [14], less required on-site labor [15], higher construction quality [16], sustainable development [17], and superior occupational health and safety [18]. With the development of prefabricated buildings, some new issues are beginning to emerge and become increasingly prominent, especially the design changes of prefabricated buildings. Bogenstatter noted that the design stage determines up to 80% of operational costs, as well as the environment impacts [19,20]. Hence, design changes can waste a great deal of time and money and even affect the quality of buildings. Overcoming this issue remains a troubling prospect for industry insiders and researchers.Design changes are common not just for ordinary buildings but also for prefabricated buildings. However, the design of a p...

“…Given the consideration of the nature of industrialisation and modularisation, off-site construction, especially high-rise modular buildings embedded with completed prefabricated modules, is an ideal implementation scheme of DfMA. Empirical projects have identified its contribution to reduced construction period as well as wastes [26,87,88]. Nevertheless, DfMA still remains at a theoretical phase rather than a concrete tool or a standard operating procedure (SOP) that can be utilised simply for general modular buildings.…”

“…Considering the great underlying potential of modular buildings, the industry coupled with academics and endeavoured to propose varied solutions involving building information modelling (BIM), and design for manufacture and assembly (DfMA) facilitating the application of modular buildings [24][25][26][27][28][29]. However, in comparison to conventional buildings, the application of modular buildings is still relatively low, especially for high-rise buildings.…”

Off-site construction has been increasingly employed due to its advantages, for instance, improved quality control, reduced skills labour, faster construction time, decreased material wastage and safe working environment. As the most cutting-edge off-site construction, modular buildings have been utilised for residential building, student accommodation, and hotel projects. However, because of existing and underlying constraints, the adoption of modular buildings is still relatively low. To reveal factors hindering the development of high-rise modular buildings, a comprehensive literature review, coupled with a focus group study, were conducted. A questionnaire survey inquiring about all stakeholders was implemented to quantify constraints. The results were further examined according to a real-life case study. This paper manifested that “Lack of coordination and communication among stakeholders”, “Higher cost”, “Lack of government support”, “Lack of experience and expertise”, “Lack of building codes and standards”, “Poor supply chain integration”, and “Complexity of connection” are the top barriers curbing the uptake of modular buildings. The findings should provide a valuable reference for stakeholders adopting modular buildings, whilst mitigating risks amid modular construction. Future research is expected to exploit building information modelling and design for manufacture and assembly to alleviate these existing constraints and promote the performance of modular construction as well.
