The Year in Infrastructure 2007 - (Page 141) WFGD Retrofit — Sioux Power Plant hitachi power systems america, ltd finalist Located at West Alton, Missouri, the Sioux WFGD is a $32.7 million project. The overall goal is to commission a flue gas desulfurization system that achieves the lowest total cost of ownership and maintains and/or improves unit reliability. Since the Sioux power plant project is the first major project awarded to the newly established division of hitachi America Ltd., hitachi Power Systems America needed to implement new software and standards to meet customers’ requirements. PlantSpace and ProjectWise enabled the firm to implement a collaborative working environment with the engineers, designers, valued customers, and other vendors. The improved communication with all parties has reduced the number of major design changes, and the use of 3D modeling has resulted in time savings due to automatic generation of 2D drawings, generation of piping ISOs with accurate material takeoff and other reports. Lihir Geothermal Power Station smec finalist Lihir Gold Limited, which operates an open cut gold mine on Lihir Island, retained SMEC to add 20-megawatts of capacity to the company’s 30-megawatt geothermal power plant. The geothermal plant is one of the first Clean Development Mechanism projects in Papua, New Guinea, and is one of only roughly 200 worldwide. Because the work involved an expansion, interfacing with existing structures, piping, and other equipment was critical. AutoPLANT assisted in resolving potential operational and maintenance interference problems prior to fabrication, saving substantial time on site by avoiding rework. A small team of engineers and a design draftsman located in SMEC’s Australian office were able to produce 3D deliverables to fabricators in New zealand and to Lihir Island quickly and efficiently to meet the project’s tight deadlines.
