| Summary: | Mechanical System including pipes supplied air-condition, heating, and sprinkler are the most time-consuming and complexity to coordinate and manage on a construction site. Moving the construction of mechanical system to a factory (assembly line) will overcome these challenges. The 3D visualization proved to be an effective tool to streamline the processes of constructing the mechanical system on a production line, assisting in investigating the best method of balancing the flow of activities and optimize the resources utilization. There are many advantages to move the construction of mechanical system from on-site to off-site for high productivity, cost and time reduction. Although degrees of automation applied in a factory setting, many activities still demand considerable physical effort. Observation techniques used to measure the physical demand of the activities performed to assemble the mechanical system is time-consuming and requires the involvement of human subject in the study. This paper presents a 3D visualization physical demand assessment (Knee and back) of workers. Based on the information using 3D visualization without visiting the site, physical demand can be assessed in order to measure the effect of changes to the construction method, the tools used and the operation height on the stress applied to knee and back of workers. Findings would give an insight on the potential injury and help to identify the ergonomic issues leading to the discomfort in the lower back and knees of the workers. The ergonomic assessment techniques could assist the early identification of work-related musculoskeletal concerns and help prioritize jobs for intervention in the construction field. |
