Due to “tear and wear”, as well as new needs and environmental changes, a key infrastructure “joint” in Stockholm, Sweden, is now being re-designed. The project “Slussen” will be finished in 2022 and involves all infrastructure diciplines and several engineering firms and architects, in Sweden as well as abroad.
Info about the project: Foster & Partners – Slussen
A very cool “cut through” which displays a section through the existing infrastructure. (Use pan/zoom in the image by scrolling on the mouse etc)
BIM is a great need here, as in many places. During the start of this project a small group of people were sat down by the governmental decisionmakers. They were chosen due to their skills in AutoCAD Civil 3D as well as the other two dominant players on this market. A lot of efforts have now been done to secure a workflow between all three softwares. This includes verifying geometries as well as attribute information. (For example the Genio-export/import for C3D will be used to some extent)
Lately it was decided that ALL designed objects, without exception, MUST contain information about:
| PARAMETER | Sample Attribute |
| Name | abcABC |
| Dimension | Width, Height, Depth, Length |
| Material | Concrete, Asphalt, Grass etc |
| Code | DCG.111 |
| Unit | m, m2, m3 etc |
| Status | A, B1, C etc |
| Accuracy (mid-ordinate distance) | 0.03m (~1 inch) in XY/NE and 0.003m in Z (Pave) |
| Responsible part/Company | A1, K1, ELU etc |
Getting “Stakeholders” setting demands like this on a major project is challenging for all of us, but it is what is needed to move the market forward. In the end we need the same demand in place for all the “bidders” to be able to spend more time and build more intelligent models, more BIM-thinking
…and this is just the beginning…
