In a previous article, I discussed the fact that the implementation process of 3D technologies and BIM is progressive and incremental. This new series of article aims at sharing some of the experiences we’ve had implementing BIM at Cadmax.

You’ll find that a successful implementation is the results of a number of smaller actions that all lead to a better use of the digital information available for each project.

The example presented here consists in eliminating, or at least reducing considerably, the time spent inserting the right steel members in the 3D model, according to the geometry and based on the structural plans.

Since more and more engineers have started using 3D, they have to work with the architect’s geometry and go through the same steps as the steel detailers, thus duplicating the work.

So, whenever possible within the contractual terms and with regards to liability, ask if an engineering model (Revit, Microstation, etc.)

The conversion files (generally IFC or SDNF) contain enough information on each piece to allow for precise and automated modeling. Softwares like Tekla Structures also let you program scripts that can interpret the conversion files and turn them into native objects. This will eliminate many hours in modeling and verification time, all the while reducing significantly the risk of misinterpretation.

If you don’t have the ability to program your own scripts to interpret the conversion files automatically, you can still use your software’s import/export functions, since these functions are more and more performing. Tekla Structures for instance imports IFC files quite well. Although some geometries and types of profiles are misinterpreted, those errors are systematic and consistent. It’s thus easy to identify and correct them by following a simple check up routine.

This kind of process fits perfectly well with the spririt of BIM that consist in sharing, using and optimizing the digital information available.
