“…These facts indicate that many problems need to be solved to fully realize the potential benefits of OSC. Moreover, there are many surveys conducted in the OSC industry to measure performance from different perspectives, for example, energy and environment [29][30][31][32], labour productivity [29,33], and market and social factors [29,34]. These surveys demonstrate the industry's desire to improve OSC in general.…”

A Systematic Review of Digital Technology Adoption in Off-Site Construction: Current Status and Future Direction towards Industry 4.0

Off-site construction (OSC) is known as an efficient construction method that could save time and cost, reduce waste of resources, and improve the overall productivity of projects. Coupled with digital technologies associated with the Industry 4.0 concept, OSC can offer a higher rate of productivity and safety. While there is a rich literature focusing on both OSC and Industry 4.0, the implementation of associated digital technologies in the OSC context has not been fully evaluated. This paper intends to evaluate the current literature of digital technology applications in OSC. Scientometric analyses and a systematic review were carried out evaluating fifteen typical digital technologies adopted by OSC projects, including building information modelling (BIM), radio frequency identification devices (RFID), global positioning systems (GPS), the Internet of Things (IoT), geographic information systems (GIS), sensors, augmented reality (AR), virtual reality (VR), photogrammetry, laser scanning, artificial intelligence (AI), 3D printing, robotics, big data, and blockchain. This review formulates a clear picture of the current practice of these digital technologies and summarizes the main area of application and limitations of each technology when utilized in OSC. The review also points out their potential and how they can be better adopted to improve OSC practice in the future.

“…Modular construction is a promising OSC method [8]. In this method, a significant proportion of construction work is conducted in a factory rather than onsite, resulting in reduced civil complaints, construction duration, waste, and cost while providing higher quality.…”

Framework for Long-Term Public Housing Supply Plan Focusing on Small-Scale Offsite Construction in Seoul

et al. 2021

The public housing demand in Seoul has been continuously increasing, but the available land for housing is insufficient. To meet the demand, the Seoul government is planning to develop small-scale housing in urban areas through various methods. Construction activities for increasing housing capacity cause negative environmental impacts, and this inevitably leads to an increase in the number of civil complaints. The complaints can be mitigated by using offsite construction (OSC) for fabricating components. However, OSC remains underdeveloped in Korea owing to concerns over high project costs. To promote OSC, the government must develop a long-term plan to secure demand for OSC. For such a plan, the number and feasibility of applicable sites in Seoul must be estimated. This study suggests a two-stage research framework: (1) estimate the number of applicable sites in Seoul using GIS and (2) conduct feasibility analyses of these sites through architectural planning. The estimated number of sites was equal to the expected supply of small-scale housing units in Seoul for 8 years, and the selected case sites were identified to be feasible. Therefore, the use of OSC for developing small-scale housing units in Seoul is reasonable. This research differs from previous studies in that the previous use of qualitative studies to promote modular construction was replaced with a quantitative analysis that included the entire Seoul area. Using the research framework, the Seoul government can develop a specific long-term plan based on the quantitative research analysis. Furthermore, manufacturers can develop plans based on the government plan and deliver returns on the higher initial costs. The contractors can reduce the higher project cost and doing so is expected to mitigate the negative perception and to promote modular construction in Korea.

“…In recent scientific developments, scholars show great interest in the problems of the construction sector growth and its impact on the environment. According to some scientists, the fact of pressure of the construction sector on the environment is highly convincing (Yilmaz & Bak ș, 2015;Razkenari, Fenner, Shojaei, Hakim & Kibert, 2020). In this context, the authors emphasize the importance of justifying the interaction of green building with the ecosystem (Kauškale & Riemenschneider, 2016;Olukoya & Atanda, 2020).…”

The proposed modelling of the relationship between the spatial and component structure of the construction industry development and the environment helped to obtain combinations of high and medium levels of the impact of integral indicators of labour, productive and foreign economic components of the construction sector on the environmental index of the region. The high level of adaptability of the models used for the period 2013– –2018 confirms the relationship between the development of the construction sector in most regions of Ukraine and the lowest level of the ecological index. This proves the scientific hypothesis about the negative impact of construction on the country’s ecosystem. The study indicates that the dynamic characteristics of the relationship between the building system and the environment should take into account the existence of direct and indirect or even “hidden” relationships between the components. The scientific value of the study consists in using models of fuzzy sets to assess the relationship between the construction system and the ecosystem based on defuzzification, which preserves the flexibility of the process of assessing the development of subsystems in construction and making decisions as to reducing the negative environmental impact in regions.
