Review of Inconsistencies between SUDAS and Iowa DOT Specifications

The objectives of this multi-part project were to review the Iowa Department of Transportation (DOT) Specifications and the Statewide Urban Design and Specifications (SUDAS) section by section and develop recommendations for possible changes that will allow the two specifications to be used together. Throughout the course of this project, a large number of differences were identified between the Iowa DOT and SUDAS specifications. These included differences in definitions, units of measurement and payment, construction materials, construction methods, and details. Addressing all of these differences, and obtaining a pair of specifications that can be used together, without conflict, will be a daunting task. It should be noted however, that while resolving all of the differences between the two documents will be a major undertaking, it was apparent during the committee meetings that representatives from both sides were open to suggestion and willing to change for the overall benefit of the public. With cooperation from both sides, the elimination of conflicts and possible merging of the two documents may take time, but is certainly achievable.
