Development of a Measuring Device for Construction Field Worker's Work Load Using Accelerometers

Construction workers are usually engaged in performing simple, repetitive motions using heavy material and tools in an uncomfortable posture and an unstable environment. These characteristics of construction work cause too much load to be placed on specific parts of the bodies of construction workers. Recently, the rapid pace of work resulting from mechanization has led field workers to be doing much more work. However, unlike manufacturing, which has a structured work environment, the environment of a construction site is not structured. Worse still, there are few tools to accurately measure the load on the musculoskeletal system, and the musculoskeletal disorders experienced by the workers have not been properly understood. As a result, it is urgently necessary to develop a tool to measure load on the musculoskeletal system. This research aims to present an MMI-based measuring device for construction field worker's work load that can measure factors of an industrial accident, such as a musculoskeletal disorders of the construction worker.
