Biomathematical modelling for managing worker fatigue in civil engineering

Abstract

Worker fatigue is an important risk factor in civil engineering and construction projects, particularly when night-time shift working is required. It is a significant cause of accidents and negatively affects health and well-being. Biomathematical models can be used to assess and reduce fatigue risk. Research funded by Tideway, the company delivering London’s Thames Tideway Tunnel, was carried out to explore the current use and knowledge of such models in tunnelling, and to produce guidance on how the models can be used for fatigue management within the wider construction industry. The research identified limitations in how the tunnelling sector currently applies fatigue modelling. Knowledge and understanding of the models need to increase throughout construction for them to be effective and used appropriately. It is also important for an industry consensus on acceptable fatigue risk to be reached.

Bus driver fatigue: A qualitative study of drivers in London

“…The researchers recognise that there is a difference between fatigue and sleepiness and were interested in both concepts throughout the research. For a detailed discussion of fatigue and sleepiness see Pilkington-Cheney et al (2020b). At the beginning of each focus group the concept of 'fatigue' was discussed in order to be sure that participants were aware of its meaning, but at the same time researchers attempted not to restrict their thoughts by enforcing constricting definitions.…”

Going underground: Fatigue and sleepiness in tunnelling operations

“…Therefore, 24/7 shifts are not essential for non-tunnelling work and tend to be used only in specific circumstances and usually for a short period of time. The widespread use of 24/7 working in tunnelling construction makes the study of the effects of fatigue on the workers particularly relevant; this can also be seen in Pilkington-Cheney et al (2020).…”

“…It should be noted here that this research recognises that there is a difference between fatigue and sleepiness and both concepts were the focus throughout the research. As noted by Pilkington-Cheney et al (2020), sleepiness is considered to result from insufficient sleep or circadian time of day, whereas fatigue is more broadly considered as resulting from work and task related activities. Relevant for this study is the fact that, in occupational settings, sleepiness and fatigue are often used interchangeably.…”

A Scientometric Analysis of Wellbeing Research in the Construction Industry

“…This research should thoroughly explore the complex interplay between work conditions, physical health, and worker wellbeing. This exploration will provide valuable insights that can be used to effectively shape policies and practices, aligning with prior comprehensive research [76][77][78]. Such advancements in safety measures have the potential to bring about substantial reductions in injuries and health problems among construction workers.…”

“…The findings indicate that hazardous work environments have contributed to a decline in worker wellbeing and productivity, often resulting in fatal injuries at construction sites [76]. There is a growing consensus that the prevalent long and extended work hours in the construction industry may also contribute to fatalities and physical health issues among construction workers [76][77][78]. Although research has primarily concentrated on this aspect, the overall impact on the wellbeing of construction workers could be significant.…”
