Risk Analysis for Design-Build Construction Projects: A Simplified Approach

Construction Projects are being implemented under different contract systems in the Midwest. Negotiated design-build has been a popular contract system in recent years. It provides various advantages through entailing the contractor to be responsible for the whole project. However, design-build turns out to be risky system for both owners and contractors unless the risks are identified, quantified and analyzed through the project execution. This paper proposes a simplified schedule and risk analysis model to help construction estimators. A hypothetical case study was used to demonstrate the applicability of this simplified model. The developed model showed a promising enhancement to be used by estimators in analyzing the risk of project schedule and cost overruns.
