Gurmu, A T (2021) Hybrid model for assessing the influence of safety management practices on labor productivity in multistory building projects. Journal of Construction Engineering and Management, 147(11): 04021139, ISSN 0733-9364
Abstract
The occurrence of accidents at construction sites has negative effects on labor productivity. Conversely, the implementation of good safety management practices (SMPs) can increase productivity. Thus, to enhance productivity, it is essential to assess the implementation levels of safety practices and analyze their effects on productivity. This study aims to develop novel models for assessing the implementation levels of SMPs and for the prediction of labor productivity in multistory building projects. Data regarding safety management practices, projects' start dates, and projects' completion dates were collected from 39 multistory building projects across Melbourne, Australia. The quantitative data were analyzed and a scoring tool to measure, plan, and monitor the safety practices influencing the productivity of construction projects was developed. Further, linear and logistic regression models were developed to predict labor productivity when a score of SMPs is determined. By integrating the models and the scoring tool, a user-friendly instrument for assessing the impact of SMPs on the productivity performance of a building project was developed. This study contributes to the body of knowledge by providing tool and models that aid construction project managers to make appropriate decisions regarding the implementation levels of the safety practices influencing building projects' productivity.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
