Project Objectives
Central Academy of Fine Arts, Qingdao consists of a teaching complex, an artist studio complex, a student apartment complex, and an auditorium complex. Massive curves convey the integrated concept of reciprocating circulation, where the teaching complex is in the overlapping state of two “Mobius bands”; several roof lights on the hyperbolic facade provide natural light for the drawing rooms; the corridor of the main teaching complex is a special-shaped large-span steel truss, hard to design.

Detailed description of the project
Central Academy of Fine Arts, Qingdao, reflects the concept of "The Open Ring University" as a future educational space. The open design makes the overall layout of the park highly integrated with the natural environment, creating a sense of rhythm in the landscape. The project of Central Academy of Fine Arts, Qingdao, consists of a teaching complex, an artists' studio complex, a student apartment complex and an auditorium complex, etc. The teaching complex in the form of "Mobius Ring" is viewed from the sky. The teaching complex is a combination of two "8’s” that convey the concept of reciprocal integration through a large number of curves.
With the parameterization function of dynamo and grasshopper, the project's interior fire extinguisher arrangement, net height statistics for each area, etc. were analyzed in bulk and the reasonableness of the design scheme was quantified in the form of scheme scoring, which significantly shortened the design cycle.
With the Sunflower's parametric insolation analysis, the main building of Mobius Circle is simulated with insolation, the duration of insolation in each area is calculated and displayed in the 3D model, the blind spots are found and corrected and optimized in time.
The curtain wall design has no basis because of the large number of spatial curves in the facade modeling, with the help of the genetic algorithm plug-in of grasshopper, the computer automatically calculates the control curve parameters, calculates the maximum slope position of the facade modeling, and based on this, the roof modeling is optimized;
in Rhino software, we run a mechanical simulation to complete the creation of the shaped roof mesh structure model, combined with the structural calculation software results, to meet the requirements. the mesh model ball points were batch numbered and labeled with the parameter control of Dynamo, then according to extracted ball point coordinates, related information can be exported to Excel data sheets. By optimizing the structure, The project is accomplished 22days ahead of schedule and 370tons of steel is saved, 4.65 million yuan (650,000$) is saved.
At the initial stage of the project, the parametric BIM software was applied to extract the drawing data to create the topography, and then the 3D model was constructed from the original geomorphological survey data, the original geomorphological survey data was reflected in the form of a grid, and there was a measurement blind spot between the grid points, so the data accuracy could not be fully guaranteed. In order to solve the above problems, the project used UAV tilt photography，creat 3D model based on ContextCapture software. Before excavation, the site environment was mapped with high precision and topographic skins were generated, considering the measurement spacing of the original geomorphological data. Based on the accurate terrain model of the construction site, the genetic algorithm is applied to input the earth balance elevation factor, and the computer calculates the earth balance elevation by itself, and according to the existing earth balance conditions, the calculated structure (earth balance point elevation) is used to optimize the original outdoor vertical design elevation, and reduce the amount of excavation and backfill (purchased soil), saving the cost of 4.2 million yuan(58,600$) and 13 days.
The overall shape of each single facade of the project is hyperbolic, there are a lot of spatial curves, how to solve the large amount of shuttering sizes caused by the hyperbolic surface, the difficulty of statistics of shuttering sizes and complex design of facade shape have become key problems that constrain the project progress. In order to solve the above problems, project department has optimized the grids of the curtain wall and the shuttering with the help of parametric software during the design and construction process, and the glass panels of each monolithic façade have been roughly fitted to a single surface. Optimized the design of 16 standard curvature modules, greatly reducing the processing and construction difficulties, saving 17 days production cycle and 12 days construction time.
In order to meet the building's flowing and beautiful facade effect, we use the parameterized software parameter adjustable features, the grasshopper software to complete the rapid adjustment of the aluminum plate slit multi-panel scheme design comparison work, and finally screen the reasonable grading scheme. The balustrade of the roof of the auditorium is a space curve design, by adjusting the analysis of the balustrade density, height, size and other parameters, combined with the original roof model using the parametric capacity of batch analysis to process the hyperbolic surface data, we generate models to obtain the best arrangement scheme, significantly improving the modeling speed.
Detailed description of openBIM on the project
During construction, two or more fire extinguishers should be placed in prominent position per 100 square meters. Using dynamo, we performed a sightline analysis of the fire extinguisher position and scored it to find out best places.
Through OpenBIM, the fire extinguisher position model is imported into archicad and the drawings are exported to tell workers safety and technical intentions on mobile devices.
A model of the auditorium complex is drawn in revit according to the drawings. Using OpenBIM, the model is imported into Pathfinder and the escape simulation is carried out under the SFPE guidelines.
The initial design has 6 escape exits. Based on the escape simulation, we added two emergency exits with a width of 2m at the rear of the stage, reducing the evacuation time significantly to 38.8s. Combined with the revit model, the external curtain wall skeleton is re-designed.
Integrate the various models of the auditorium and import them into navisworks for collision checks, and then return the results to revit via OpenBIM.
Using dynamo, the ID of the conflicting member is extracted and isolated in batch through the parametric procedure, which makes a visual display of the collision site and greatly improves the efficiency.
The design department meets to discuss and solve problems until all isolation components are eliminated.
Use Revit modeling to assist with plan layout, tower crane layout, and material processing area layout. According to the current site conditions, the current stage of the adjacent holes, scaffolding protection, temporary electricity protection, machinery and equipment protection, fire protection facilities areas are marked. Import the model into Lumion through OpenBIM for roaming animation and scheme presentation.
