Abstract: New fast track construction projects worth more than $100 billion are being implemented in Makkah to improve services being rendered to millions of pilgrims who come for Hajj and Umrah. The new development projects in Makkah, including largest expansion of the Grand Mosque. The time factor has become increasingly as an outstanding requirement on this construction projects. In the present work, the question acceleration of construction projects is moved in the center. Consequently, innovative structures, procedures and techniques are required for a time-oriented project management; consistently and purposefully focus on the reduction of process time and not to shrink back from entirely new, unfamiliar processes. so recommendations for the efficient management of construction projects always need to be developed taking into account the specific objectives and framework. This article discusses also the deterministic method, the simplified stochastic method and the application of the Monte-Carlo simulation as a stochastic method. With increasing of level of detail of the information content of the project and increases the calculation effort with the result that the range of the construction time decreases, thus the accuracy increases. Based on this range, finally the construction time of the building as well as the part times for the individual construction phases are determined.
