“…However, precast concrete technology could not eliminate on-site operations because the joints still required local manual work (Konishi et al, 1996). Also, quality issues caused by flawed engineered interfaces disturbed users and urged hard-to-solve responses.…”

“…The mix of precast and conventional work set specific takt times that were usually in between those estimated to zairai kōhō and full prefabrication. A survey by Konishi et al (1996) with several companies identified the most recurrent merits among 51 composite construction method variations. A breakdown of these factors revealed that the leading one was time shortening (43), followed by labour-saving (shōryokuka) (38), quality improvement (29), personnel reduction (shōjinka) (28), proficiency effect (shūjuku kōka) (27), cost reduction (26), and material-saving (24).…”

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.
