As there, one of the greatest virtues that provides the representation of buildings in a three dimensional format is the ability to pre-visualize a pre-construction phase the possible disagreements in the future construction. For the part I played in MEP models, I have to coordinate all the systems together, coordinate the same facilities with the proposed structure avoiding collisions with beams, columns, or other structural element and coordinate certain steps needs Vertical or horizontal stroke caused by the pipes, ducts or trays.
This implies an exercise in communication with the parties involved in the project, both with people from my office and with external partners such as architects or steel construction. I’m always talking about a project design phase, the first moves of the chess game, in more advanced stages are other characters such as project managers, construction managers, etc..
At the end of a lot of coordination and communication that you had reached the moment of truth, the moment model revision. The most laborious part of this review, in my opinion, is the detection of collisions between elements. I have worked closely with the architect and the reporting structure only changes we have been doing in our respetivos models but still there is always something you miss. In most cases it is the sag of the beams, a recalculation may have increased and are now colliding with my air ducts.
I know that Revit incorporates that option so dear “Interference Chek” but honestly turns me off that long list of items that I have to select and give the little button for Show me frame the element itself, what I want is an overview, something more visual, more agile to discover, so my intention was to go to other software to serve my needs.
For part of the solution Autodesk Navisworks we of course offers a full palette of tools for detecting collisions apart from being the most popular among users of Revit.
The purpose of today’s article is to present a tool similar to Navisworks, more limited in features but for my needs it works beautifully. The well-known house Tekla provides this tool free of charge and the truth is that it works very well managed both for collisions and for the review of our models, yes, based on the models exported in IFC format. Each collision is marked with a symbol on the three-dimensional model is therefore just what I wanted, something that at first detect the most problematic, of course corrections have to do with the Revit but it serves to achieve my initial goal.
