The Society of American Military Engineers (SAME) Denver Post and Philadelphia Post along with the US Environmental Protection Agency (EPA) are hosting a series of webinars based on talks given at recent Design and Construction Issues at Hazardous Waste Sites (DCHWS) Symposiums. The mission of the DCHWS symposiums is to facilitate an interactive engagement between professionals from government and the private sector related to relevant and topical issues affecting applications of engineering and science associated with cleaning up hazardous waste sites. The symposiums also serve as a platform to facilitate the exchange of information, encourage dialogue, share experiences, and build and enhance communication among design and construction professionals. This presentation will address the following:Identification and quantification of risk during progressive phases of design;How to mitigate risk through contract language or added cost;Provide examples of how risk costs are estimated, assigned, and weighted due to probability and impact of risk.How multiple risk components are analyzed and a cost strategy is developed.Provide examples of high risk projects and mitigation as well as low risk projects and mitigation.
