Shaw was retained to design and construct a 585-megawatt circulating fluidized bed (CFB) electric power generation station. Known as the Virginia City Hybrid Energy Center (VCHEC), the project included a 650-megawatt steam turbine generator and two CFB boilers, associated infrastructure and equipment, and vendor supplied systems. Project development began in 2007 using PDS and MicroStation-J. To improve engineering and construction performance, Shaw transitioned to Bentley’s more advanced modeling and collaboration software in 2008. The transition required Shaw to install and configure a new modeling platform, and train design and construction teams, without impacting budget or deadlines.
With four major areas of CAD work being performed by different design firms, Shaw configured the new system so its designers could work in vendor controlled areas with little difficulty. By developing weekly schedules of deliverables and training availability for each worker on this 70-person project, Shaw completed design training with improved engineering performance throughout the transition. Shaw sent four experienced designers to the construction site to train the construction team on using the data and design models in the new environment.
Shaw experienced no impact on budget or the 58-month completion schedule, despite the transition to the Bentley PlantSpace environment on this active, USD 1.5 billion project. Construction was completed with no rework by resolving interferences in 3D design using Bentley’s advanced integrated solutions. Bentley’s collaborative and accurate software tools enabled design reviews to be conducted efficiently and ahead of schedule, provided construction access to the models and reduced man-hours on site. Retooling and advancing 3D design and construction modeling improved communication, engineering and construction efficiency, and overall project execution.
Shaw used Bentley PlantSpace Model Control System (MCS) so multiple vendor models were superimposed as one, enabling Shaw to design in vendor-controlled areas. Generating an intelligent composite construction i-model using Bentley Navigator allowed the construction team onsite access to the 3D design information. The combination of MCS, i-models, and Bentley Navigator provided effective collaboration necessary to coordinate design and construction among the teams and stakeholders. With Bentley’s modern, integrated application suite, Shaw implemented a construction-driven design schedule saving thousands of onsite hours.
