Advanced BIM Modeling Made It Possible

 

Thanks to thorough planning, advanced BIM-modeling and a fruitful solution-oriented dialogue, the team behind the realization of this project – the client and owner, construction companies, all subcontractors and last but not least the architects from A-Lab along with their trusted BIM advisors from Cad-Q, were able to complete the complex design of the Statoil construction on schedule.The result is a building where they all expressed great satisfaction with the project.

A-Lab, led by architects Geir Haaversenin and Odd Klevin, won a competition in 2009 to design the Statoil regional and international offices. The office building is at the site of the old airport’s former car park. The structure consists of five office lamellas of identical size, stacked on top of each other.

The building design draws on the oil industry’s own construction forms and techniques. The steel superstructure enables the different modules to cantilever up to 30 meters. Escape stairs and services are concentrated in four giant concrete cores, which also stabilize the superstructure. The façade consists of about 1600 prefabricated elements with integrated windows, insulation and solar-shading, a highly energy efficient solution with no visible fixings in the entire facade.

 Initially, when the A-Lab team started designing and planning the Statoil building, it was still in the early days of BIM management. However, the BIM manager and architect at A-Lab, Angie Arroyo Mendez, saw no other way than to start working with BIM using IFC.

– We did not use IFC then, but it was necessary – I knew we needed to go in that direction.

No doubt, Angie, with her Costa Rican background can be very convincing. The programs were still subject to new developments, but she knew that in the end a construction of this complexity would benefit from BIM modeling. With Cad-Q as their trusted CAD and BIM advisor, she had no fears in throwing herself and the team into this ambitious project.

– Our cooperation with Cad-Q during the years has proven to me that when I need to develop new routines I can always go to Cad-Q and ask Håvard Dagsvik or one of the other consultants for advice.

According to Håvard Dagsvik from Cad-Q, this project was very exciting;

– This was a special task for us back then. Revit IFC export wasn’t yet fully developed and many issues came up. We discussed the issues one by one directly with the development team at Autodesk, and together we found the solutions now implemented in Revit.

Customised solution: Naviate

With the façade consisting of prefabricated elements with integrated windows, insulation and solar-shading in blocks measuring 3 metres in one row and then 3 metres of windows in another row and so on, A-Lab did have some serious challenges in the beginning; when exporting these to IFC, the whole façade became one solid block with no windows!

– We talked to Cad-Q about this and they actually solved it by programming a new feature as an add-on to Revit, called Naviate. As a professional, you need to understand that there are limits to what programs like Revit can do for you. Many people blame the programs but in my world, we need to think differently if we want to be professionals. For instance, it is still common to use pdfs for transfer of data and drawings but in a BIM project DWF files are the right formats to use for exchanging files. PDF is like using a floppy disk instead of a USB stick!, Angie exclaims.

At one point in the process, we had 4000 errors occurring in Revit with warnings and I got on the hotline to Håvard. Not long after Håvard presented a method to work around these errors.

– This was impressive, Angie smiles, – the solution was precise, clear and they managed to communicate it so well to our team, almost like a recipe, easy to work with!

New thinking requires new methods and skills

As well as using the right files, Angie wants to work right from the start and she is not afraid of new challenges. With the Statoil project, they had a very productive relationship with the entire team behind the project. We were all able to work in the same 3D model and we needed to know exactly how to do this right.

– If you want to keep your competitive edge, you need to team up with people with the right technical knowledge. I do not mind taking risks as long as I know that the people behind me can back me up. With Håvard and the guys from Cad-Q, I knew we were in good hands.
