Value Engineering in Practice: A Look at the Clarks Viaduct in Nebraska

The value engineering alternate for the Clarks Viaduct in central Nebraska has demonstrated that it is now technically and economically feasible to precast concrete superstructure solutions to compete with structural steel in long span bridge design. The concept described in this article can be used with l-girders, inverted t-beams, and box beams. The design eliminates concerns about positive creep restraint moments at the piers. Not only will the precast concrete superstructure result in long term savings in terms of lower maintenance costs, but also will provide immediate benefits to the owner and contractor in terms of lower construction costs. The overall construction savings in the Clarks Viaduct project was approximately $100,000 over that of the initial steel girder alternative.
