Constructability and Challenges of the Slims and Duke Bridges Project

This paper discusses constructability implementation, lessons learned, and challenges encountered during the design and construction phases of projects. Slims River and Duke River Bridges replacement project on the Alaska Highway was selected as a case study. The Slims River and Duke River are two major rivers in the Yukon. The replacement of the Slims River and the Duke River bridges on the Alaska Highway is part of the US-funded Shakwak project. The Shakwak project is part of the Shakwak agreement between the Canadian and United States Governments for the purpose of improving the Canadian highway sections that link the Alaskan panhandle to the Alaskan interior. Since 1977, more than $1.8 billion has been spent rebuilding and maintaining the Alaska Highway through the international Shakwak Agreement. Slims River and Duke River Bridges Replacement Project is one of the major improvements undertaken under the Shakwak project. Several challenges were encountered and mitigated during work on this project including: Environmental Sensitive Zone; Complex Hydraulics; Active Seismic Zone; Densification of Liquefiable Soil; Traffic Management. In this paper we will analyze the factors that impacted project costs and summarize the specific approaches that were adopted for design and project delivery. The authors concluded that innovation during the design phase and constructability input at the preliminary and design phases of a project has a positive outcome on project budget and schedule during the construction phase. Ultimately, recommendations and strategies for future projects are presented herein. For the covering abstract of this conference see record control number 201111RT334E.
