Systematic review on the identification of safety risks in off-site manufacturing (OSM)

Abstract

Purpose Off-site manufacturing (OSM) has emerged as a method of modern construction that provides several benefits including achieving lower costs, a quicker schedule and environmentally friendly solutions. Although numerous researches are available that advocate the adoption of OSM, the devotion towards OSM safety is somewhat limited. However, OSM invariably generates safety risks, including dynamics and uncertainty in safety management. There is a unique call to have an investigation on the identification of OSM safety risks. Design/methodology/approach To provide a full picture on the OSM safety, a systematic literature review was adopted based on interpretivist philosophical stance. The literature search was conducted in key electronic databases to identify OSM safety-focused publications. Bibliometric analysis was adopted to identify co-occurrences of keywords and collaboration among authors in OSM safety-related research publications. Content analysis was conducted to provide a taxonomy of OSM safety risks. The identified studies were critically analysed to determine the focus of OSM safety research and provide future research directions. Findings The results demonstrated frequently appeared OSM safety aspects while highlighting the limitedness of collaborative research outputs in common authorships. Content analysis subsequently unveiled safety risks in OSM under human, organisational and work environmental factors. A critical analysis of extant literature revealed seven research classifications of OSM safety. Directions were offered to enhance OSM safety by applying principles of targeted safety management concepts, technology-driven safety measures and bespoke training programs. Originality/value This study provides a comprehensive review on the identification of safety risks throughout OSM while presenting the avenues useful for the development of OSM safety management strategies.

The Influence of Organisational Safety Climate Factors on Offsite Manufacturing Safety Performance

“…With this process, OSM facilitates improved productivity, sustainability, and safety [3,4]. Although there are potential safety benefits by utilising OSM for building construction, there is evidence of increased safety incidents in OSM compared to traditional construction that require consideration [5]. For example, in the USA, sub-OSM categories such as prefabricated wood building manufacturing and prefabricated metal building and component manufacturing have recorded higher rates of injuries and illnesses during the period between 2017-2019 [6].…”
