| Risk management has been important in the construction of the new Woodrow Wilson Bridge outside of Washington, DC. |
The CEVP team also evaluates how risks can be lowered and costs can be managed or reduced. "Using the CEVP, our goal is to deliver projects within the target cost range and schedule range," says Mark Gabel, Program Manager for WSDOT's Cost Risk Assessment Office. "The CEVP analysis is important in replacing general and vague planning for contingencies with deliberate planning for identified and quantified risk events." The CEVP is required for any project with an estimated cost of $100 million or more, while a Cost Risk Assessment (CRA) is required for all projects with an estimated cost of $25 million to $100 million. Other projects that could benefit from formal risk assessments are also identified for CRA or CEVP analysis.
WSDOT is using value engineering (VE) principles as well to identify high risk areas and recommend mitigation measures. For a project on I-90 in the Seattle area, for example, a VE team was formed after the CRA was completed to review and make recommendations on high risk and high cost project areas that had been identified. "This process ultimately reduced the project budget by $16 million," says Ken Smith, Deputy State Design Engineer for WSDOT.

| The new 12-lane Woodrow Wilson Bridge near Washington, DC, is scheduled to be completed in 2011. |
Risk management has also been important in the construction of the new 12-lane Woodrow Wilson Bridge outside of Washington, DC. The $2.43-billion project will replace the existing six-lane bridge built in 1961, which now carries nearly three times its original intended traffic load, and upgrade four interchanges. Almost 200,000 vehicles cross the bridge daily.
In 2004, FHWA conducted a risk assessment as part of its oversight of the project, which is scheduled to be completed in 2011. Project elements reviewed included security, schedule, materials fabrication and availability, change orders, maintenance of traffic flow, work zone safety, utility conflicts and delays, environmental agreements, and the project acceptance process. Elements were classified as low, medium, and high risk. For example, low risk areas included acceptance procedures, while medium risk areas included utility conflicts and delays and change orders. High risk elements included project security, materials fabrication and availability, and project schedule. "The project team then reviewed project activities to determine where additional oversight would be required and what types of risk mitigation measures could be used to keep the project on track," says Jitesh Parikh, major project oversight manager in FHWA's Maryland Division office. To help mitigate security risks, for example, parking has been prohibited in Jones Point Park, which lies underneath the new bridge. An emergency response plan has also been introduced that is tied to the U.S. Department of Homeland Security's threat levels. If threat levels rise, such security measures as conducting ID checks of workers would be instituted.

| As part of the Ohio River Bridges Project, a new bridge will be built connecting downtown Louisville, Kentucky, on the left, and southern Indiana. Existing bridges to the downtown area are shown here. |
A risk assessment performed on the cost estimate for the Ohio River Bridges Project, meanwhile, has helped to keep the project on track. Two new bridges will be constructed, connecting Louisville, Kentucky, and Clark County, Indiana, and a key interchange will be rebuilt where I-64, I-65, and I-71 meet in downtown Louisville. Construction is expected to begin in 2007 and be completed in 2020. In 2003, FHWA partnered with the Kentucky Transportation Cabinet and the Indiana Department of Transportation to analyze the initial project cost estimate and recommend any needed changes. Risk factors that could affect the estimate were identified and ranked. "We looked at areas of risk that could change and also at contingencies that had been included, and adjusted the contingencies based on the perceived risk," says Larry Heil, then-Project Management Team Leader in FHWA's Indiana Division office. For example, traffic maintenance costs were increased based on the complexity of the project area, and right-of-way costs were also adjusted after examining more current evaluations. While the estimated project budget rose from $1.7 billion to $1.94 billion, the new estimate ultimately provided a more realistic picture of project costs and needed contingency plans.
