Simply placing the word "smart" before any kind of architectural or technological term, or any term for that matter, seems to convert it into something new and futuristic. Some examples, such as the smart city, smart industry, or smart commerce show us that the "smart" adjective is already more common than we think, and that, moreover, it doesn’t sound that strange anymore. The smart building is also a novel concept used in today’s architectural world. The difficulty of discussing this concept, as with every innovative yet ambiguous term, is finding a clear definition of it. There is already much writing on it, and we won’t find an absolutely clear definition, but generally, we could define a smart building as: "A construction that strives for full energy efficiency in its usage, reaching this goal thanks to integrated and automated management and control of all its systems."

When we talk about BIM methodology, we refer to a new and very technologically advanced form of work. Yet if we pay attention to the language of BIM conversations, we might notice that we always speak in future tense: "in 10 years' time everyone will…" or "this is the methodology of tomorrow." Is this methodology not currently mandatory? And if not, when it will be? To begin grappling with the first of these queries, below we summarize how BIM is currently dealt with around the world.

Currently, specialized technical skills in the use of BIM methodology are in high demand, especially in the field of architecture. Even during the pandemic, job offers in this area have remained relatively stable, especially due to the flexibility of this methodology and the possibility of working collaboratively from remote locations. However, when looking for a new job, those interested in BIM should consider several questions: What am I specialized in? What areas are in highest demand? What type of professional BIM role is the most common?

Floors, roofs, ceilings. Speaking in a very generic way, they are practically all the horizontal elements that we can find in the construction of a building. These three parts have a very similar way of modeling in Revit and this is the reason why when learning this software, they almost always appear one after the other. The order is usually a rather logical and therefore similar order: starting first with the floors, later the soffits and, finally, the ceilings. All this, clearly after having modeled the exterior and interior walls of our building.

One of the great difficulties we encounter with “classic” plan delineation methodologies are ramp and stair projections. It has always been difficult to avoid calculating the ramp’s slope, as well as the dimensions of the footprint and riser of the communication staircase between two floors of a building. Do they comply with current regulations in my country? Do they adapt to the project standards? Will they be accurately calculated?

Thanks to great advances in project modeling using BIM methodology and Revit software, these calculations can be made with greater ease. However, these elements will probably be an aspect of modeling that will bring us the most difficulties in the project phase.
