ContextCapture Reality Mesh Optimizes Hubei Wind Farm Site Scheme - 1

CASE STUDY Project Summary Organization: Hubei Electric Power Survey and Design Institute Solution: Utilities Transmission and Distribution Location: Macheng, Hubei Province, China Project Objective: • Generate 49.5 megawatts of wind power to supply Macheng. • Develop the site scheme for a 24-turbine wind farm in the Dabie Mountains abutting the city. • Design and construct wind power generating sets, pylons and bases, booster station, maintenance platform, and maintenance road. Products used: AECOsim Building Designer, LumenRT, Bentley Raceway and Cable Management, Bentley Substation, ContextCapture, Navigator, OpenRoads®, ProjectWise®, ProStructures, STAAD.Pro® ContextCapture Reality Mesh Optimizes Hubei Wind Farm Site Scheme Bentley Technology Reduces Design Time, Shortens Construction Period on Turbine Project Windy Peaks 51-meter fan blades and 63-ton tower sections. The Hubei Energy Group’s Macheng Caijiazhai Wind Farm Project is part of the growing wind power industry in China’s Hubei province. The 24-turbine farm is generating 49.5 megawatts of the planned capacity for supplying power to Macheng City. As general contractor, Hubei Electric Power Survey and Design Institute developed the site scheme for the mountainous location and designed and constructed the wind power generating sets (turbines), pylons and bases, 110-kilovolt booster station, and associated equipment. Hubei Electric Power Survey and Design Institute also designed and constructed the maintenance road that accommodated transport of the massive turbine components and construction equipment. Using Bentley technology for reality modeling, 3D modeling and design, and project management saved a total of 50 resource days, shortened construction by 20 days, and reduced project delivery costs by CNY 200,000. Hubei Energy Group looked to a leader in the power industry to serve as general contractor and complete this complex project within 12 months. Fast Facts Site Challenges • Reality meshes provided context for site plan development and 3D digital design. Hubei Energy Group New Energy Development Co., Ltd., was established in 2014 as an integrated business platform for the research, application, project investment, construction, and operation of new energy technologies. The now completed and operational Macheng Caijiazhai Wind Farm Project will contribute to the development of wind power in central China, eventually generating 80 megawatts of green energy for about 700 villages and towns. The wind farm will also help reduce power transmission loss from the Macheng grid. • Integrating the digital terrain model with the 3D design model for the maintenance road minimized earthwork, produced accurate quantities, and guided construction. ROI • ContextCapture shortened field investigations by 10 days and OpenRoads shortened road design and construction by 10 days. • Bentley Substation and AECOsim Building Designer improved booster station design quality. • ProjectWise streamlined project information management, saving at least 10 days. The city of Macheng is in northeastern Hubei, overshadowed by the Dabie Mountains. The site selected for the Macheng Caijiazhai Wind Farm is in the mountains near Futianhe Town, Macheng City. The location presented difficult terrain along mountain ridges up to 700 meters high and steep slopes with gradients of 20 to 45 degrees or more. The challenge was not just to position 24 wind turbines at optimal points, but also to design an access road capable of transporting massive equipment to each position. The generating sets included Reality Check With nearly 60 years of industry experience, the Hubei Electric Power Survey and Design Institute’s expertise in power supply projects included the use of advanced digital design technology, including software from Bentley’s portfolio of applications. Bentley technology was implemented throughout the project to achieve the expected precision, accuracy, quality, schedule, and cost. To collect accurate and complete information about the project site, the design institute conducted topographic reconnaissance over a large portion of the mountainous area. The organization used an unmanned aerial vehicle (UAV) to perform oblique photography and LiDAR surveying to capture precise data and images of otherwise inaccessible locations. ContextCapture, Bentley’s reality modeling application, provided an intuitive modeling environment to build a landform reality mesh of the entire site. Entering wind resource analysis data into this 3D engineering-ready model enabled the Design UAV oblique photography and LiDAR point cloud data were used to create reality meshes, which helped the project team plan site developm

"We used the hybrid model consisting of landform reality modeling and 3D models of the booster station and fan to demonstrate the final panorama. In conjunction with decomposition of the model's details and simulation of construction and transportation, we enabled the management team to have a full understanding of the whole project's construction process before construction started." — Pingzhong Ding, ProjectManager, Hubei Electric Power Survey and Design Institute Find out about Bentley at: www.bentley.com Contact Bentley 1-800-BENTLEY (1-800-236-8539) Outside the US +1...
