Glazed structure model. Update 1

Engineering | Production | Logistics | Assembly

In the March 2017 we posted an article about glazed structure modelling in Tekla. Below is the follow up on this.

We have launched a project where the assembly will start in end this year. Project is located in Gothenburg, Sweden. The building envelope is unitized façade with total area about 3500m². These elements have partially non-transparent zones with integrated blinds and dark anodized claddings.

The project will be designed by two teams simultaneously – one will be using the traditional CAD software, the other will be working in Tekla Structures and using our glazed structure plug-in set.  Since it is a real project with specific schedule, then we are limiting some risks using only the new designing process. At the same time it will ensure a healthy competition. If Tekla team will finish project on time, it could be used for production, logistics and assembly team. The whole value chain will benefit from building information model.

The aim for this development project is to create a complete design process and prepare data for the whole value chain (production, logistics, assembly). Our goal is to reach highest level of detailing for glazed structures in Tekla. This will also allow to spot some “dark” areas where there is no automation yet.

So far we have created model with element – and we have the second and third model in mind.

Façade element frames were modeled with our own plugin- Glazed Structure Frame. The building consist of 381 frames (333 assemblies). The color represents type of frames. Processes for glazed structures modeling was similar to heavy structures. We put dwg and ifc references in the model and modeled according to them.

When all element frames were finished the optimization was started. There were some elements that should be identical but they were not. The issue was that references were not precise. Actually there were more sketches than exact information. There were also too many points to snap and it was easy to make some imperfections.  Reference preparation for this model took about 2 hours. Frame modeling was done in 1.5 days. For frame collision issues and optimization there was spent 3 days.

The conclusions at this stage are the following – modeling time at this stage span 38 hours. Obviously, at each detailing level we made much more unique elements so it is essential to make first stages as precise as possible. While working with this project we found some possible improvements to our glazed structure tools. We are working to implement them in the newest versions that will be available in the near future.
