Reassigning Construction Laborers Based on Body Motion Analysis

Abstract

Construction laborers perform multiple labor intensive and physically demanding tasks, which exposes them to the risk of work related musculoskeletal disorders. When construction laborers sustain these injuries, they are typically reassigned to other tasks. The body motion involved in carrying out the assigned task should have limited use of the affected body part(s). This has implications on the productivity and health of a reassigned laborer. Traditional approach to reassigning laborers are subjective and ignores the effect of the tasks on the affected body part. To address this limitation, an ergonomic analysis framework is proposed to quantify the risk factors associated with body parts during the execution of construction tasks, so as to enable the reassignment of construction laborers to tasks that will impose the least strain on the affected body part. Preliminary results are provided to demonstrate feasibility.

A Survey of Work-Related Pain Prevalence Among Construction Workers in Hong Kong: A Case-Control Study

“…Construction sites are generally known to be one of the workplaces with high risk of injuries and poor health [2,3,4,5,6]. Construction workers, in particular, are prone to painful musculoskeletal strains and injuries because of their labourious and strenuous manual jobs [7]. The pain severity is aggravated by their harsh working environment, which is associated with irregular working hours, unstructured mealtimes, tough and dusty work, and outdoor and indoor heat, etc.…”
