CH2M HILL wins 2006 BE Award for


Exton, USA, 21 December 2006 – CH2M HILL, a company into full-service engineering, construction, and operations, has won 2006 BE Award for its American Electric Power – Mitchell & Mountaineer CPS Treatment Plants project in West Virginia. The award category was “Plant: New Technology Adoption.”

American Electric Power (AEP) is installing flue gas desulfurization systems to improve environmental performance at its Mitchell and Mountaineer coal-fired power plants. The new forced oxidation limestone scrubbers will reduce sulfur dioxide emissions by 95 percent. However, they also will produce a high total suspended solids and total dissolved solids purge stream that needs to be treated prior to discharge.

Working with AEP, CH2M HILL used Bentley tools to evaluate treatment options for the purge stream. It developed 3D models and engineering analysis models, and used various visualization techniques, including dynamic 3D PDFs, to convey options for design and construction. The options all met the potential effluent regulations and water quality criteria, and satisfied construction limitations caused by tight space in the existing plants. The firm used Bentley’s PlantSpace Piping 3D modeling tools to design the new system’s piping requirements.

The 3D visualization enabled by MicroStation provided CH2M HILL with an innovative way to satisfy AEP’s concerns with space issues. For example, interactive, animated 3D PDFs provided visual proof that a crane and front-end loader could operate within the confines of certain project areas.

CH2M HILL’s use of Bentley solutions also included the development of analytical models. Because the 3D models interoperate with Bentley’s STAAD structural engineering software for analysis and design, the project team was able to produce the structural analysis results directly from the model. The results were then fed back into the 3D modeling tools – eliminating redesign and back-checking, saving design time, and improving coordination.

The BE Awards of Excellence, which are judged by an independent panel of industry experts and presented at an evening ceremony during the annual BE Conference (, honor the extraordinary work of Bentley users improving the world’s infrastructure. These projects set benchmarks for their industries and showcase the imagination and technical mastery of the organizations that created them.
