Abstract |
Measuring and evaluating the workload occurred to construction worker have not been arrived at a certain maturity because it is not easy to standardize construction operations and these operations are subject to dynamic changes This paper presents a method that measures quantitatively the workload demanding to the workers engaged in waterproof operation and tests for statistical significant differences among the unit tasks associated with the operation Three hypotheses involved in the unit tasks (eg, a primer painting and a polyurethane coating) are established as follows: [Hypothesis 1] Given a same amount of work, the average heart rate occurred to the worker engaged in the urethane coating task is higher than that in the primer painting task [Hypothesis 2] Given a same amount of work, the average break time required to the worker engaged in the polyurethane coating task is longer than that in the primer painting task [Hypothesis 3] When measured immediately after completing the two tasks, the body parts that the workers feel uncomfortable were arm (t = 2449) with statistically significant difference; neck (t = 0632), shoulder (t = 0000), waist (t = 1987) and wrist (t = 0655) with statistically no significant difference |
