The rhythms of project life: a longitudinal analysis of work hours and work-life experiences in construction

A diary data collection method was used to collect data from project-based construction workers in a large civil engineering construction project in Melbourne, Australia. Data capturing the number of hours worked, satisfaction with work-life balance and capacity to complete required tasks at work and at home were collected for 21 consecutive weeks. A strong correlation was found between hours worked each week and participants' work-life experiences. Data were subjected to time series modelling procedures and weekly work hours were found to significantly predict participants' capacity to complete tasks at work and at home, but not their satisfaction with work-life balance. The impact of work leading up to a major project milestone was found to increase the predictive capacity of the time series models, indicating that project events have a significant impact upon the work-life experiences of project-based workers. The period of intense work prior to the milestone (the opening of a new ramp on to an operating freeway) contributed significantly to an immediate reduction in capacity to complete tasks at home. Further time series modelling revealed that recovery opportunities associated with workers taking a short, temporary break from work can also contribute to improved work-life balance. It is proposed that construction organizations use the naturally fluctuating workloads implicit in project work to 'build' recovery opportunities into project schedules.
