The task demands assessment methodology

The production parameters of construction operations, such as the speed and organisation of an operation, affect the exposures and risks that workers face. The task demands assessment is a new methodology for measuring the accident potential of construction operations and quantifying the effect of production variables on the safety risk of an operation. The method considers two key factors for assessing the potential for accidents:(a) the exposure to a hazard, and (b) the ‘task demands’ during the exposure, which reflect the difficulty to do the work safely. In the heart of the task demands assessment methodology is the identification of the production variables that affect the exposure and the task demands. These are identified though observation of the actual operation and input from the activity participants. The paper describes the methodology, and presents a case study that measures the safety risk of a concrete paving operation. The case illustrates how this methodology can be used to analyse the ef...
