Sustaining Infrastructure Project Summary Gippsland Water Maryvale, Victoria, Australia Project Objectives • Eliminate odor, corrosion, and capacity issues • Provide a sustainable solution that benefits the community and • Recycle wastewater for industrial • Preserve fresh water resources Products Used • AutoPLANT Piping • Bentley Data Manager • Bentley Datasheets • Bentley Instrumentation and Wiring • Bentley Vision Gippsland Water Factory Alliance Uses AutoPLANT on Wastewater Treatment Facility Fast Facts • Common database provided • 3D visualization enhanced design • Bills of material automatically pleted early • Facility saves about three billion iters of fresh water each year • The alliance saved 20 weeks of drafting work, which paid for soft- ware, training, and implementation • Automatic isometric generation saved over five thousand hours • Gippsland Water indicated the value of as-built 3D models for ifecycle asset management was Design a Sustainable Solution Gippsland Water provides water and wastewater services to about 130,000 people in 41 towns throughout Centra Gippsland, Victoria, Australia. For nearly 60 years, raw wastewater from nine towns and Australian Paper's Maryvale Mill discharged to a regional outfall sewer, causing serious odor, corrosion, and capacity issues. The (AUD) $260 million Gippsland Water Factory was designed to provide a sustain- able and economically responsible solution. AutoPLANT, Bentley's premier plant design engineering suite, helped to keep costs down by streamlining workflows, reducing design time, facilitating procurement, and producing as-built models for lifecycle asset management. The Gippsland Water Factory was delivered by a project alliance that included Gippsland Water, Transfield Services, CH2M HILL, and Parsons Brinckerhoff. The alliance partners worked collabor- atively and shared equal responsibility for design, construction, and commissioning. Many factors made this ambitious project quite challenging. In addition to technical issues associated with treating the odiferous pulp-and-paper wastewater, the project alliance contended with the simultaneous construction of Australian Paper's (AUD) $500 million Maryvale Mill upgrade just one kilometer away. Intense political pressure to deliver the project on time and on budget called for a tight timeline, close coordination, and carefully planned construction schedules. Partners Going Different Directions Starting at Maryvale and extending east 87 kilometers to Dutson Downs, the 1950s-era regional outfall sewer was half concrete pipe and half earthen drain. The 41 kilometers of open drainage generated a significant stench, which in turn caused community outrage. The simple solution would have been to pipe the open drain. Instead, Gippsland Water took advantage of the opportunity to go beyond compliance and provide a sustainable solution that benefited the community The new wastewater treatment infrastructure, dubbed Gippsland Water Factory, included the Maryvale treatment plant, 78 kilometers of new pipeline, and eight new or upgraded pump stations. The project serves a population of With four alliance companies and a large multidiscipline team working on the project, there was significant risk that the partners would take the design in different directions using different products. This risk was realized in the early days of the project, after about 100 piping and instrumenta- tion diagrams (P&IDs) were created. Using non-intelligent P&IDs caused a major problem as there was no consistency in 2D and 3D symbols, and there were both duplicate and incomplete asset tag information throughout the documenta- tion. At the same time, manual lists were being created for equipment, valves, and instruments. The lists were out of date as soon as the P&IDs were updated, and there was no way to synchronize the diagrams and lists. AutoPLANT Provides Integrated, To deliver this complex project on time and on budget, the Gippsland Water Factory Alliance needed design tools that would boost productivity, efficiency, and accuracy. The alliance recognized that Bentley software would save time in both design and rework. "Early in the design process, we were heading in all different directions using different products and using AutoPLANT really did save us," said Mark Saunders, CAD manager, Gippsland Water. The AutoPLANT suite of products was chosen as the com- mon - and mandatory - design technology because it links to a central project database and generates intelligent 2D drawings and 3D models, from which bills of material and isometrics could be automatically generated. Mark Saunders explained, "Because there were four companies involved, each with a large number of staff, we realized it was critica for the project to have a central database that we could al access, enabling us to get the most up-to-date information The first order of business was to recreate the 100 P&IDs using AutoPLANT P&ID to enforce consistency, standardize symbols, eliminate duplicate asset tags, and generate a live shared database across engineering disciplines. Details were added via Bentley Data Manager and Bentley Instrumentation and Wiring. This database was then used to rapidly create
