MicroStation Descartes Helps Pave the Way to 2002 Winter OlympicsOne of the most critical transportation projects involves rebuilding the interstate freeway I-15, a 17.5-mile stretch serving as the major north/south route through Salt Lake City. Upon examining the freeway's capacity, UDOT determined that repairing the crumbling infrastructure was not enough. I-15 needed to be torn out, ramps, bridges and all, and replaced from scratch. The design/build contractor Wasatch Constructors--a joint venture of industry powerhouses Peter Kiewit Sons, Inc., Granite Construction Company and Morrison Knudsen Corporation--was formed specifically to complete the I-15 reconstruction project. Wasatch, in turn, contracted a joint venture of Sverdrup Civil, Inc., and De Leuw, Cather & Company, a subdivision of Parsons Transportation, to design the new highway. They decided early on to standardize on Bentley software for the entire I-15 project. MicroStation Descartes was used to prepare corridor design documents, taking advantage of existing engineering documents of the original highway design and interim repair, aerial photography and newly surveyed details of the corridor. "Parsons works with numerous state department(s) of transportation (DOT) and an extensive array of other transportation agencies in the United States and throughout the world," says Bill Guthrie, CADD Production Manager. "The use of Bentley products enables us to coordinate our files, our users and our clients, as most DOT's now use MicroStation. We have used Bentley products since Bentley first started developing MicroStation, and we are moving forward with MicroStation/J and the Engineering Configurations deployment." Using MicroStation and MicroStation Descartes, the team was able to review and sometimes redesign the concept geometrics on features of the project. These reviews and redesigns enabled reductions in grading and earthwork quantities, as well as shortenings of bridge lengths. It also allowed the implementation of the accelerated design schedule. It saved an estimated $ 1 billion in overall costs on the operation. "The general functions of MicroStation that many people take for granted are extremely valuable assets to our operations," comments Guthrie. "With the advanced reference filing, raster support, workspaces and other aspects of Bentley software, we saved ten to fifteen percent in both time and money. We've never done a job of this magnitude with Bentley's competitors." The full story of the rebuilding of Salt Lake City's I-15 will be featured in the near future on the Bentley website.
