Presence of risks and unceria inties inherent in project development and implementation plays
significant role in poor project performance. Thus, There is a considerable need to have an effective risk
analysis approach in order TO assess The impact of different risks on The project objectives. A powerful risk
analysis approach may consider dynamic nature of risks throughout The life cycle of the project, as well as
accounting for feedback loops affecting The overall risk impacts. This paper presents a new approach TO
construction risk analysis in which these major influences are considered and quantified explicitly. The
proposed methodology is a system dynamics based approach in which different risks may efficiently be
modeled. simulated and quantified in terms of Time, COST and quality hy The use of The implemented object
oriented simulation methodology. To evaluate The performance of the proposed methodologv it has been
employed in a bridge construction project. Due TO the space limitations. the modeling and quantification
process [or one ofthe identified risks namely "pressure to crash project duration" is explained in detail.
