Abstract
Slab concreting is one of the important tasks in construction in which structural element exercises to generate horizontal flat surface at the roof or ceilings. The study was conducted to evaluate the working postures of 68 laborers performing concrete mix laying on the floor for slab concreting. The ERIN, RULA and REBA methods were used to evaluate workers' real-time work patterns followed by design of collection and discharging tables designed and modelled. Biomechanical and lifting/lowering analysis were performed on the manikin while working on the newly developed table. Results indicate that laborers are working in vulnerable condition with extremely high ergonomic risk and exposing to work-related musculoskeletal disorders. The most exposed parts of the body are the Lower back (85.29%), shoulders (66.18%), arms/hand (48.53%). Newly proposed collecting and Eviction bin table minimizes the risk of work-related musculoskeletal disorder on the different parts of the body.
