should be repeated for each project delivery method that survives the Tier 2 process. Due to cost escalation on large transit projects, since 2002, the FTA has required that each "New Starts" project undergo a formal risk-based cost estimate.

If a project goes into the Final Design Phase without a decision on a project delivery method, the agency will lose the opportunity to effectively use alternative delivery methods and will be limited to the traditional DBB approach. At the end of the Conceptual Design Phase, the agency usually has not done a detailed risk analysis.

Risk factors are rated, always from the perspective of the owner agency, according to the effect of a particular project delivery method on that risk factor. In the hypothetical case shown in Table 6.1, from the agency perspective, DBB is seen as having a favorable effect on the risk factor of "permits/approvals." The agency thinks that it is the best party to obtain permits/approvals and that it can most effectively do this using a DBB approach.

If this risk analysis is not a requirement (for example in projects that do not apply for federal funding) , then it is suggested that the proj90 A Guidebook for the Evaluation of Project Delivery Methods Risk Analysis Cost/Schedule - Ranked Risk Factors - Risk Factor 1 - Risk Factor 2 … Quantitative Approach (See Fig.

However, the choice of the project delivery method is a natural outcome of a risk analysis exercise because one of the most important benefits of any risk analysis is risk allocation/mitigation. A properly selected project delivery method is an effective risk mitigation instrument that can help keep project costs low and minimize project delays.

Both analyses are based on a risk-allocation exercise that will determine major risks to the agency under various project delivery methods. In the qualitative approach, the decision-makers carefully examine each risk factor and deliberate the anticipated effect of each risk factor on project cost and schedule.
