HOUSTON—(BUSINESS WIRE)—February 25, 2009— Sargent & Lundy LLC, a worldwide leader in professional services for the electric power industry, won a 2008 Be Award of Excellence for “Innovation in Power Generation.” The $1 billion project, the new Dry Fork Station Unit 1 power plant near Gillette, Wyo., will provide a highly reliable, environmentally sound, and economical source of electric power needed to support the region’s growing economy. In addition, it will burn locally mined Powder River Basin coal, further supporting the area economy. The project is featured in the new publication “The Year in Infrastructure 2008,” available online from Bentley Systems, the leading company dedicated to providing comprehensive software solutions for the infrastructure that sustains our world, at www.bentley.com/YearInInfrastructure2008. The Dry Fork Station Unit 1 power plant presented the large project team – spread over many organizations, locations, and design platforms – with a complex industrial-design challenge. The team was able to substantially reduce the quantity of issue-for-comment drawings through collaborative model reviews using Bentley Navigator. This desktop application enables users to visualize, navigate, and interact with intelligent 3D models of large, complex facilities using both graphical and non-graphical facility information. Of the estimated 7,600 physical-plant drawings expected to be issued, approximately 85 percent of the review-cycle prints were eliminated, saving many thousands of man-hours due to decreased document handling, printing, and mailing. The project moved smoothly into the construction phase on schedule, with an optimized design and the necessary foundation for efficient construction and operation.

Commenting on the project, Rich Marshalla, project manager and vice president, Sargent & Lundy, said, “We executed a very successful, advanced-generation, clean-coal technology project. The Bentley software tools were instrumental in allowing us to effectively meet the schedule and the customer’s expectations for the highly complex project.”

Marshalla continued, “For example, use of MicroStation and Bentley Navigator empowered us to improve online collaboration and reduce the quantity of comment drawing releases during the design-comment cycle phase. It also allowed us to improve contractor understanding by performing online constructability reviews and to facilitate contractor input early in the design phases. At the same time, the software made it possible for us to establish and control space allocation within the 3D model by enabling us to conduct regularly scheduled design reviews, thereby allowing the project team to reduce interferences and to stay on schedule.”
