Case Study for Getting Probability Distributions of Some Basic Construction Activities

Abstract

Under the title ‘Management’, it should be considered many things simultaneously such as time, money, manpower, machinery and equipment and their interactions. After that consideration, it should have also optimized them to improve the workflow, scheduling, resource usage etc. Well, it is not easy in the uncertain environment of construction sector, which has a many stakeholder, has long completion times and is highly dependent on the human labor. It is necessary to model this uncertainty. Most importantly, we need the probability data for these models. In this study a housing project consisting of 13 floors was analyzed, the completion times of 20 activities are given for each of these floors and the distribution of the duration of each activity implemented on each floor was obtained. Those activities are repeated 13 times by the same team and with the same equipment. According to that results, activities mainly fit the Logistic, Log Logistic, Lognormal and Weibull distribution. After determining that which distribution for the activities is best suited to our data, the real time data is adjusted to this distribution and the average completion time of this activity for this building is obtained. Based on the average completion time of each activity, the completion time of the entire building was obtained. The aim was getting the stochastic data from a real project to use in different management stage in future. Besides, the number of samples will also be increased and the deviations in the resulting distributions and their causes will be examined.
