The Waste Comprehensive Treatment Facility Project of Xiong’an aims to make the area a “waste-free city.” The 220,000-square-meter facility will process 3,060 tons of garbage, kitchen waste, solid sewage, and medical waste per day. This process will be invisible to residents, as the facility will be underground and topped by a park. However, the design presented designer China ENFI Engineering Co., Ltd. with challenges including ventilation, tight space for equipment, fire protection, seepage control, and a short schedule. The team moved from 2D drawings to digital design using Bentley applications, unifying all collaborators among 13 design specialties and helping them determine how to overcome challenges through 3D modeling and construction simulation. In the process, they improved efficiency by 130% and greatly reduced errors. In addition to effectively building within curved mountainous terrain, they eliminated the need for four cranes and avoided rework, saving CNY 13.7 million. Planning construction sequences in advance reduced construction time by 50 days.
