THE FACTORS AFFECTING THE METHODS OF CONSTRUCTION PROJECTS SCHEDULING: AN STATE OF THE ART AND OVERVIEW
Journal Title: ASIAN JOURNAL OF NATURAL & APPLIED SCIENCES - Year 2017, Vol 6, Issue 4
Abstract
The successful completion of the project within the estimated duration is the main target to many schedulers, this will cause the contractor to gain more reputation, and the owner will start to reap the revenue from the project. Thus, effective scheduling of construction projects is a crucial aspect of construction management to avoid any delay and deliver the project within the estimated time, cost, and quality. The difficulty of scheduling process results from three main reasons; uniqueness of the projects even though they have the same function, variability between projects regarding cost, time, and quality, and ambiguity which refers to unclear data, and inaccurate estimate. Thus scheduling is a heuristic process, which depends mainly on a high knowledge and experience. This enables the scheduler to take the right decisions when defining the precedence relationships between activities and assigning the available resources to different activities. As a result, it will reduce resources’ idle times and increase the utilization factors of different resources. Traditional scheduling methods have many drawbacks especially when the projects become very big and more complicated, which makes the control process very difficult. This problem put high pressure on researchers to develop more realistic and effective methods of scheduling construction projects. Although many articles published to solve certain problems in scheduling construction projects, still the critical nature of scheduling process sexists. The main objective of this article is to highlight the main factors affecting project scheduling and the developments in scheduling techniques during the last five years by reviewing the different articles published in this field. This provides a good base to many researchers interested in scheduling process to contribute more in this field.
