Computer-based models are widely applied in the ergonomic analysis of the workplace. These models are mostly based on frameworks and methodologies founded on a combination of observation-based, checklist, and artificial intelligence techniques (OWAS, RULA, REBA, and QEC). Computer-based models such as ErgoBuild (Nussbaum et al. 2009) were designed to provide an early assessment of both ergonomic and productivity concerns and applied to residential construction projects using panelized walls. The model provides design schedules, construction plan alternatives, and simulation animation of the construction process by using the available number of workers, available time for work, and maximum acceptable ergonomic risk as input. ErgoCheck, based on an ergonomic assessment framework by Inyang and Al-Hussein (2011), adapts various ergonomic assessment techniques to develop a computerbased model suitable for assessing modular and panelized residential construction tasks in a factory.
