Underground Design-Build Do’s and Don’ts for Owners and Contractors

From the experience of the authors on recent large infrastructure Design-Build projects this paper reviews major lessons for Contractors and Owners in the delivery of large Design-Build infrastructure projects and some major pitfalls and warnings to both Owners and Contractors. The paper is written from both the Design and Construction perspective. A case history is presented that details the approach employed to ensure a quality project consistent from the initial design phase through construction and outlines the strategy used to guide the Design-Build process to an acceptable completion. Suggestions are made for Contractors and Owners for handling the Design and the Construction elements of Design-Build contracts.
