Maximizing Pavement Design for Highway Design Build Projects Lessons Learned from I-5 Everett HOV

In traditional Design-Bid-Build projects, the engineering consultant generally has no financial incentive to minimize the construction cost as long as it stays within the client's budget. As a result, the design may be conservative, resulting in needless dollars being spent during construction. Design-Build projects require all participants involved to rethink their traditional roles on a project. The Owner no longer dictates the final design, but instead sets the design parameters, requiring the Design-Builder to determine the final design. Teamed with the contractor, the designer now has to look at the financial impacts of the design, considering material costs, procurement, subcontractor involvement, traffic and schedule. Therefore, the designer and contractor together can develop alternatives that meet the design requirements, while reducing costs. The contractor is being paid on a lump sum basis, so minimizing impacts to cost and schedule, while still meeting the design parameters, means more money in the Design Builder's pocket. The focus of this presentation is on a case study of the pavement design and construction for the I-5 Everett HOV Project located about 30 miles north of Seattle, Washington. The Design-Builder will present on the challenges of working as a Joint Venture between designers and contractors and the impact it had on the final product.
