确定在基本建设项目的设计和施工中使用成本和进度风险概率分析的过程、益处和影响。介绍了全面的文献综述和实践状况调查的结果。还通过多个案例研究讨论了概率方法的“如何”和“为什么”，并通过验证调查确认所有发现。最后，介绍了团队的实施资源、风险登记工具和分层风险登记参考卡。注:IR280-2中包含的实际工具。

Identifies the process, benefits, and implications of using probabilistic analysis of cost and schedule risks in the design and construction of capital projects. Presents the results of a thorough literature review and a state-of-practice survey. Also discusses the "how" and "why" of probabilistic methods through multiple case studies, and a validation survey to confirm all findings. Finally, introduces the team's implementation resources, a risk register tool and a laminated risk register reference card.NOTE: Actual tools included with IR280-2.
