Time Contingency Assessment for Construction Project

Abstract

Construction projects often delay due to constrain effects. Contingency plan is to be considered to prevent delaying of the project. Project schedule optimisation can be done using different tools such as Primavera, Microsoft project, to calculate the total time required in the project and to complete the project in given schedule. These optimising tools help in preventing the project delay and helps in calculating the time duration for the project. In construction project, project time contingency and project uncertainty are required for accurate scheduling in which changes made does not affect the overall duration of the project. The critical path calculated and considering the factors of constrains, project gets complete within the deadline provided. This thesis comprises of three objectives, first, to find the factors delaying the project, second, to rank them according to their importance in delaying the project and third, to calculate the contingency time of the project using SAPA method and Monte Carlo simulation. We use stochastic allocation and project allowance method for project scheduling with the help of Monte Carlo simulation in @ Risk software and questionnaire to rank the factors affecting time delay in the project. A six floors + ground floor green building is used for the allocation of project time contingency and to calculate the contingency time of the project.
