Construction labor productivity (LP) is the key element in forming the success of construction projects. Numerous studies on the topic of critical success factors (CSFs) within construction LP have been conducted, but the results have rarely emphasized developing factors related to managerial function behaviors (MFBs) and examining its relationship with construction LP, a key criterion for measuring construction effectiveness; these less researched topics were the aims of this study.
The empirical research studies were designed to develop managerial behavior's attributes based upon a literature adaptation and focus group studies (FGSs). Then, the causal relationships between MFBs and LP were examined by drawing on project-specific data collected from 195 completed construction projects in Vietnam, which was to the approach to an exploratory factor analysis (EFA) and Bayesian model averaging (BMA) technique.
The findings reveal that the MFBs' attributes were organized into a four-factor MFB framework: “cooperation emphasis (COOP),” “people orientation (PEOP),” “commitment emphasis (COMT)” and “leadership promotion (LEAD).” The findings reveal that COOP, PEOP and COMT have significant effects on LP.
The success of this approach is expected to broaden academic's horizons of factors affected LP and suggest a useful tool for supporting the project management professionals in enhancing construction LP and sustainability.
