* Model for the construction industry using pre-determined times Jasper Van Gilsa, Leo Vaningelgema Abstract This paper is based on our work experience with Office-line. This company prepares standard times for companies in the industrial sector. Standard time is productive time that is required and achieved by an employee. Standard time contains everything that is necessary for the work specified to be completed. The reason why Office-line only prepare standard times for the industrial sector rather than the construction industry is due to the repetitive nature of the work. One example is the car industry which uses assembly lines. In the construction sector, this kind of repetition is not so evident. There is repetitiveness in some …show more content…

This includes that we have to make a more than one measurement to become a reliable average for these tasks. A second importance that we need to take notice of using chrono, is the performance level at which the employee is working. An execution time of a specific person can not be used as a reference for or employees and as a consequency we can’t set these specific times as standards. Tools that can help us by adding a tempo to our measurements are tempo scales. These scales will make sure that execution times will be calibrated and that we become standard times. Standard times can be executed by any valid employee in a social acceptable space of time. Bedaux-scale This tempo scale was designed by the Frenchman Bedaux. He saw that not all employees were working at the same performance level. So he had the idea to add a value from 0 to 100 to the performance levels where 100 stands for the maximum pace which can only be performed for a short period and zero for doing nothing at all. A score of 60 is the level every valid employee should be able to perform for a complete week, 8 hours per day. For his scale, Bedaux compared the working tempo with walking (60) and running (100) that we know starts from a speed of 7,5 km/h. Walking at the speed of 4,5 km/h matches the score of 60 Bedaux-points. Berenschot-scale * For some people the Bedaux-scale was a bit
