“…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...

“…Prefabrication is a technology in rapid construction of building by produce the main elements from a different place and delivered to location for installation [8]. Characteristics of prefabricated buildings are design standardization, industrial production and assembly construction [9]. Prefabrication is one of the answers in solve current building demands by re-produce products on a large scale for inventory and the speed of the building process [10].…”

“…The design focuses on the method which the project will be completed, where the possibility of using components is produced outside the site and logistics and assembly efficiency [14]. The main purpose of the DFMA is to assist designers in optimizing and increasing the success rate of prefabricated building design by integrating other stages of knowledge and information facilities into the design stage [9].…”

The increasing need for bridge infrastructure in Indonesia requires an efficient and lean construction process. The aim of this research to evaluate the use of precast concrete elements on bridges based on the Design for Manufacture and Assembly (DfMA) criteria. DfMA is a principle design that considers the process of manufacture and assembly components based on the following criteria, i.e., simplificity of design, number of components, standardization on elements or material and ease of handling. Analytical Hierarchy Process (AHP) is used to determine the weights for each criteria. Data were collected through observations on a bridge project, interviews with engineers and questionnaires. A typical girder and slab bridge is used as an object for DfMA-based evaluation. The results of evaluation design of prefabricated components to recommend some that are suitable for use in bridge construction. The last case study was taken to one of the bridge construction projects on the newly completed highway is done to identify the prefabricated components used. Bridge analysis and re-design are carried out with the DfMA concept, including costs incurred, resource scheduling and discussions of project risk. The results of analysis with simulation design giving efficiency 28,83% simplificity of design; 8,74% number of components and standardization on elements or materials; 25% ease of handling; 51,53% assembly time; 23,39% cost of work and 18,87% duration time. Finally, the level of risk of work received such as weather conditions and work safety is reduced. In closing, recommendations were given for further DfMA development.

“…Ceniceros et al [26] developed a sustainable decision support model for selecting optimized design parameters for prefabricated floor slabs. Similar research made by Jensen et al [27] aimed to demonstrate CAD tools as a mean to create design automation alternatives for modularized building systems, whereas Yuan et al [28] combined parametric design of Building Information modelling (BIM) with Design for Manufacture and Assembly (DFMA) as a mean to overcome the unsuitability of design systems, which have been developed for nonprefabricated buildings, on prefabricated buildings. Another research by Said et al [29] presents a platform optimization model for panelised wall systems.…”

A B S T R A C TA great deal of interest in off-site construction has been remarkable over the last decade. However, building on the rooftops of existing building has not been given a significant importance as a subject of research, despite its dependence on off-site construction and prefabrication. Thus, this paper develops a novel conceptual framework to support a multidisciplinary decision making for selecting off-site prefabricated constructional system for roof stacking. The multidisciplinary approach includes each of safety, logistics, cost, time, environmental impact, and quality of construction as major criteria in the decision making process. This paper is the outcome of an exhaustive investigation of more than 136 roof stacking projects built during the last 20 years. The development of framework is supported by a feedback validation loop based on semi-structured interviews with experts in the field of roof stacking and off-site construction.
