The CNY 720 million Inner Mongolia Ethnic Minorities Cultural Sports Center in Hohhot, China, will establish the region as a world-class destination for cultural and sporting events. The facilities include a grand stand, race track, stables, performance hall, wrestling arena, sports museums, and parking plaza spread over 2,092 mu. China Aerospace Construction Group and Chongqing Liansheng Construction Project Management provided overall project management and integration of design and construction.
The team deployed AECOsim Building Designer’s BIM advancement to provide 3D project control, which enabled multi-discipline design coordination, building optimization, pipeline coordination, and material quantity reduction from design through construction. The 3D model of the project enhanced optimization and collision detection across disciplines, facilitating cooperation between the steel structure and curtain wall system, arrangement of errors occurred in equipment pipelines of the irregular building design, as well as the tight scheduling requirements mandated by the owner. Earlier stage simulation of complicated processes eliminated errors and allowed the project team to manage the design cycle synergistically, and to understand a common goal.
By leveraging a BIM methodology, China Aerospace Construction Group provided a foundation for inter-discipline cooperation, employee training, and intensive design management. The integration of Bentley software reduced pipe collision and helped designers compute precise earthwork quantities. In one case, optimization reduced earthwork from 370,000 to 70,000 cubic meters, saving more than CNY 20 million. The building design software also reduced design time, errors, and rework rates. Conducting 4D construction simulations from the model helped to choose a rational construction scheme.
Using AECOsim Building Designer with ProjectWise for real-time, collaborative design reduced the repeated modifications typically necessary with traditional 2D design. China Aerospace Construction Group used Bentley Navigator for clash detection and resolution of the complicated pipeline system to significantly improve design quality and reduce construction delays resulting from collisions. Using a BIM methodology to simulate multiple construction scenarios early in the design cycle allowed the team to expose issues before construction, and enabled designers to choose the most economical construction scheme.
