Since the early 1990s, the construction industry has taken some interest in the application of lean production to its own case. A new body of research led by the International Group for Lean Construction (IGLC) has been exploring new techniques for the industry. In this article the techniques developed for lean construction are compared with those of lean manufacturing. Differences between the manufacturing and the construction cases showed why lean production does not fully suit the construction industry. Although some elements are in an embryonic state, lean construction has built a set of techniques that are transferable to any constructor. Lean manufacturing and lean construction share many common elements despite their different techniques. The need for a joint combination of technical and human elements shows that both approaches conform to a common sociotechnological design.

Background: Behaviour-based safety (BBS) is one of the promising methods implemented in industry to reduce the incidence of accidents and injuries. Researchers have reported diverse BBS applications in various industries. The diversity of applications and results reveals a need for systematic review and meta-analysis to evaluate the overall effectiveness of BBS to improve workers' safety and health. Objective: To quantitatively assess the effectiveness of behaviour-based safety (BBS) interventions in reducing accidents and injury occurrence in occupational settings. Methods: A critical appraisal was conducted to assess the methodological quality of study. A meta-analysis was also performed to identify the direction and size of the effect. Results: Thirteen studies met the inclusion criteria with a poor to marginal methodological quality. Eight studies achieved a statistically significant reduction in accidents/injuries after conducting a BBS intervention. The overall metaSAR (0.60, 95% CI 0.72-0.97) displayed a statistical significance in reducing accidents/injuries. Conclusions: A statistically significant reduction in injuries/accidents was observed after conducting a BBS intervention in a workplace. However, this statistical significance should be interpreted with caution, due to the poor to marginal methodological quality of studies included in the meta-analysis. Reliable results require interventions with high methodological quality based on the specific needs of the workplace.
