“…Although a number of different analytical methods have been used to define the components and characteristics of the LCA program, most were originally designed for refrigerators, microwave ovens, general consumer goods, or other raw materials and resources [47][48][49]. LCA in a building can be evaluated by applying international LCA guidelines, such as ISO 14040 [50], to assess the environmental impact across the entire process, which is assessed separately by goal and scope definition, list analysis, and impact assessment [51][52][53][54][55].…”

Modular construction is an innovative new construction method that minimizes waste and improves efficiency within the construction industry. However, practitioners are hampered by the lack of environmental and economic sustainability analysis methods in this area. This study analyzes the embodied carbon emissions and direct construction costs incurred during the production phase of a modular residential building and provides comparison to an equivalent conventional residential building. Major drawings and design details for a modular residential building in South Korea were obtained, and the quantity take-off data for the major construction materials were analyzed for a modular construction method and a conventional construction method using a reinforced concrete structure under the same conditions. Focusing on major construction materials during the production phase, the embodied carbon emissions assessment revealed that adopting a modular construction approach reduced the environmental impact by approximately 36%, as compared to the conventional reinforced concrete method. However, in terms of the direct construction cost, the modular construction was approximately 8% more expensive than the conventional reinforced concrete construction method.

The Evolution of Prefabrication Based Modular Housing: Expectation and Challenge

The building construction industry is on the verge of a massive transformation of construction practices caused by constant pressure to evolve and adapt to increasing global and urban challenges. The neglect of the vernacular building method in the building production process was first realized by using fairly cheap and abundant concrete and reinforced concrete as a substitute for stone and wood, which are the materials of vernacular structures. The world continues to face housing pressures caused by an insufficient inventory of housing units accessible to local residents. This study aims to explore the history of the development of modular-prefabricated construction with a qualitative-histography approach. This goal can be achieved through a series of processes ranging from reviewing relevant literature, discussing findings, and presenting contemporary research themes. The idea of prefabrication was integrated to reinterpret the contemporary sense of dwelling. However, the lack of a concept of knowledge and an understanding of well-defined prefabrications can hinder the integration of methods and theories on the subject. The results of this study show that there is ambiguity regarding the advantages of prefabricated construction practices that are developing today so it becomes a challenge for construction business actors to provide guarantees to the public of the quality of the promised products.

“…7 Therefore, the infill method is somewhat better at securing structural performance compared to the stack method and is primarily used in the construction of tall buildings. 9 However, the stack method is currently more popular because the infill method requires skilled workers and, in the event that the process control plan is not established properly, space to store modular units on site. [10][11][12] When the stack method is used, large shear forces, such as from an earthquake or wind loads, are concentrated on the intermodular connections [13][14][15][16] ; therefore, quality control of the intermodular connections becomes critical.…”

Modular construction is a method of construction that involves prefabricating modular indoor spaces in a factory and then assembling them at the construction site. However, dimensional errors made during production in the modular manufacturing factory may hinder assembly at the construction site and delay the entire construction process. In particular, as the quality of intermodular connections determines the structural performance and serviceability of the entire modular building, meticulous quality control is required for the connections. In this study, a method is developed for inspection of the intermodular connection locations to meet the requirements of being accurate, inexpensive, easy-to-use, rapid, and operable by a single person, and then tested in a modular factory. The proposed inspection method consists of three parts: (a) a laser meter mounted on a gimbal, (b) target reflectors based on the tumbling doll principle, and (c) a mobile device as a remote control and for data storage, data post-processing, and visualization of results. The proposed inspection process was tested on a modular unit that had been manufactured at a modular factory; the proposed method outperformed the conventional method in terms of accuracy, inspection time, and work safety. The proposed inspection method allows the accurate and rapid inspection of locations of intermodular connection holes and, thus, its use in modular factories is likely to improve the economics and efficiency of modular construction.
