“…In Japan, the early design of PBPs was initiated by government-funded corporations in the second half of the twentieth century to facilitate development of the public housing sector (Kobayashi, 2016). The Daiwa House Industry Company developed Midget House in 1959, which is the origin of mass-produced prefabricated housing in Japan (Matsumura et al, 2019). In 1962, the Guidance for Incombustible Prefabricated Residential Building Construction was issued by the Government Housing Loan Corporation (a loan corporation fully funded by Japan's government), which contributed to the establishment of a public financing system for PB development (Uchida, 1968), and allowed PB projects to receive special financial support from public departments.…”

Compared to buildings constructed in situ, prefabricated buildings (PBs) offer many environmental benefits in terms of carbon emissions, energy consumption, material consumption, and waste generation. To mitigate adverse impacts by the building sector on the environment, PBs have been widely applied in many countries. Although PB policies (PBPs) have played a significant role in guiding, supporting, and promulgating China's PB development, few studies have systematically investigated these PBPs. As a result, the evolution of PBPs in China is not clear, which limits practitioners' overall understanding of PBPs. To bridge this knowledge gap, a bibliometric analysis method was employed to review 136 PBPs issued in China from 1956 to 2019. Through text mining, a co-word network analysis, and a collaboration network analysis, we mapped, visualized, and described the PBP system over time. The evolution of PBPs can be divided into four phases: exploration (1956-1995), fluctuation (1996-2005), steady improvement (2006-2015), and rapid growth (2016-2019). Our findings indicate that the PB policy targets, policy objects, policy tools, performance indicators, and the collaboration structure of policymaking agencies have changed significantly across these phases. Lastly, the PB experience in China was compared with those of countries exhibiting higher levels of PB development, which can serve as a reference for PB development.

“…The works of Yashiro (2014) and Matsumura et al (2019), who interacted with those groups, are some of the few reports published in English conveying a "domestic view". The ZEMCH network, led by Noguchi (2016), has spread and popularised information about Japanese prefabrication, but they often recall the specific examples of the modular housing niche.…”

This paper provides a contemporary outlook on the concept, features, and achievements of the composite construction methods (fukugōka kōhō) developed in Japan between the 1970s and 1990s. The topic has not been widely publicised abroad, contrasting with prefabricated housing and construction robotics research conducted in the same period. However, the "compounding" approach can play a pivotal role in overcoming the present-day challenge of making digital construction technically possible and economically feasible. This research has employed two research methods. The first was a bibliographic survey of historical construction records and academic articles to grasp how fukugōka kōhō helped construction firms to deal with the pressing business and technological needs of that time. The second was focus group interviews with experienced engineers who came across the yielding effects of the compounding strategy and are now developing and implementing new elemental technologies integral to "smart construction systems" as part of R&D initiatives and productivity improvement management policies, which are tacitly lean. The awareness that try-out implementations of digital construction methods reassemble those past experiences put light on the possibility of resurging lean-ish hybrid production models to ensure competitiveness and reliability advantages in the transition period of technological maturation.

“…Japanese car manufacturer, Toyota, has been manufacturing automated modular houses since 1960s (Bell, 2018). Matsumura et al (2019) report that Japan's automated offsite industry now supplies about ten thousand houses each year. Some countries in Europe are also well established in the automation of OSC.…”

PurposeAutomation facilitates production activities within offsite construction (OSC) projects through computer-controlled and mechanised systems that can be programmed to deliver various products in a self-regulating sequence. Despite known benefits of automation to offsite production, the level of automation adoption in New Zealand is low. This study is an effort to understand the current status of automation within the New Zealand construction industry and to identify the barriers and enablers to its uptake.Design/methodology/approachThis study utilises the qualitative approach of semi-structured interviews (open-ended questions). Using a referral sampling strategy (snowballing), fifteen New Zealand industry experts were interviewed, and the data collected were analysed using qualitative content analysis.FindingsThe study found that there is a weak business case for full automation. Four main categories of barriers to the uptake of automated OSC were identified, including requirement of high capital cost, lack of education about automation and OSC and non-existence of regulations to support OSC. It was noted that financial supports to the OSC sub-sector in form of subsidies, tax waivers, and enhanced leasing model could enhance the uptake of automation. Further to this more awareness about OSC's automation and regulations suitable for OSC could enhance the confidence of business owners to invest in this area.Originality/valueOriginality of this paper stems from the fact that, not much attention has been paid to investigating the uptake of automation for OSC sub-sector of construction industry in New Zealand context.
