Abstract
The methodology of development of building project schedules, proposed in the article, is based on an attempt to combine two independent approaches in order to increase the probability of fulfillment of time limits planned in the CPM schedules during the performance of construction works. The analysis of the risk associated with the planned building project will allow for the determination of those tasks which are most threatened by the exceeding of the planned duration time. The application of time buffers, their proper location in the schedule and the determination of their duration, taking into account the expected risk of delays, allow to develop the schedules that contain the appropriate time reserves to compensating for the possible delays. Such a schedule may serve not only as a reliable basis for the determination of the expected deadline for completion of construction works, but also for the management of these works during performance. Selected components of MOCRA and MP-KP methods were proposed in the article.
