Statistical Methods for Construction Delay Analysis
The occurrence of delay is common in most construction projects, due to various reasons and causes before or during construction phase. As the delay impact on time and cost overrun, analyzing of these delay(s) makes easy to give responsibility to concern party. This helps to avoid or minimize delays in future work. Numerous analytical methods are available for analyzing these impacts and selection of proper method depends upon: statistical data available, time available, limitation of method and money available for analyzing. However, information of activities which are responsible for project delay and their magnitude provides the baseline for investing the cause and assessing the responsibility for project delay. This paper reviews research methodology suggested for assessing construction delay factors by analytical methods as well as with the help of computerized schedule analysis methods. The purpose of this study is to review various analytical computerized schedule analysis methods for analysis of construction delay factor.
