Determination of construction process duration based on labor productivity estimation: A case study Determination of construction process duration based on labor productivity estimation: A case study

Original language description

Monitoring labor productivity is one of the key issues in the construction project planning process how to decrease construction costs. The CONTEC automated system combined with statistical methods assists in predicting the amount of time required to complete construction works according to the specified number of deployed work crews, technological processes and labour required for certain production in person-hours. This study applies statistical analyses and probability theories of plastering work, which represents a labor-intensive construction process. The goal of the research is to determine the probability of completion of the construction process based on monitoring the mean value of performance. By application of statistical analyses has been proved a decrease in the performance standard compared to the planned values given in the CONTEC database. The decrease in performance, which was also caused by occurrence of days with unfavorable climatic conditions and demonstrated by performing interval estimates based on the collection of statistical data, was afterwards confirmed by a relative frequency test. The measures have been taken, in terms of establishing the required number of personnel capacities for com- plying with the construction schedule.
