Vitharana, V H P and Chinda, T (2021) Development of a lower back pain prevention index for heavy equipment operators in the construction industry: System dynamics modelling. International Journal of Construction Management, 21(7), pp. 677-693. ISSN 1562-3599
Abstract
Lower back pain (LBP) due to the whole-body vibration exposure is a common health problem among heavy equipment operators in the construction industry. This study utilizes a system dynamics modelling approach to develop a dynamics model of the LBP prevention index in Sri Lankan construction industry to assess the current level of LBP prevention maturity and plan for long-term improvement. The developed dynamics model consists of five key factors, namely (1) personal, (2) organizational, (3) equipment, (4) job-related and (5) social-context, together with their 17 associated items. Both secondary and primary data are used for the model development. Secondary data are extracted from several literature reviews, while primary data are obtained from interviews and observations on sites. The simulation results show that the LBP prevention index reaches the highest maturity level, which is level 5, at 39 years. Personal, job-related and social-context are key factors that enhance the LBP prevention index in the long-term. A construction company should focus more on human aspects than equipment acquisition, as this helps to achieve higher levels of maturity in the long-term. A construction company can use the developed dynamics model to plan for an effective LBP prevention program to enhance the LBP prevention index in the long-term.

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
