Statistical Analysis of Delay Factors and Success Factors on Building Construction Projects

It has been observed that almost all project in construction industry delayed and over budget. Project schedule delays due to changes occur during construction, consequently impacting the project in its completion. Delay in construction projects is defined as late completion of project as compared to the planned schedule. Delays in construction projects are quite expensive; sometimes they may result in severe damages to involved parties. The time and cost for the performance of project are usually important to the employer and contractor. Project delays always contributed as expensive to all parties. The purpose of this research is to identify critical success and delay factors which can help project parties to reach their intended goals with greater. Totally Twenty-Eight delay factors & seven success factors were shortlisted to be made part of the questionnaire survey. According to the case study results, the most contributing factors and categories (those need attention) were discussed, some recommendation were made in order to minimize and control delays in construction projects. Also this project can serve as guide of all construction parties with effective management in construction projects to achieve a competitive level of quality and a time effective project. Statistical Prediction model for estimating actual project duration with delay was implemented on a real case study & tested the accuracy of prediction model.
