BIM, second part

As I mention in a previous post, “What is BIM?” the way of working in architectural firms is changing.

Although we are reluctant to change our way of doing things, the question is to decide WHEN we will change. We may wait or the inevitable, but we will take this step.

One of the factor that determinate the continuity of our profession lies in adjusting to changes. Put more dramatically, only you will survive if you adapt to new conditions. In relation to the design process,

BIM is the present.

The way of developing a project is a revolution. But not as much as we can imagine.

The process is altered:

THINKING – DRAWING – MEASURING – BUDGETING – MAKING

What you need to know is that it is altered to improve it.

With any CAD system, we draw lines. With more or less shortcuts, but we trace geometries. With BIM we draw entities. That is, we define, for example features of a wall (thickness, height, component layers, representing in different scales, etc.) and we draw a vector between two points.

Little by little 🙁 we generate the three-dimensional building model.

 

Building in 3D has its advantages

For now, it forces us to make an extra effort. However, it has rewards.

The first ones are derived from the 3D geometry

Making perspectives and checking what we already know or intuit.

Plans, elevations and sections. We do not draw the project plan by plan.

We extract information sectioning the BIM model.

Changes are not done plan by plan. The model is modified and the plans are automatically updated. This really is a great reward!

While it demands more, it also gives more.

The second rewards are reflected in the measurements

By building in a parametrical way, all elements drawn are measurable. Just as with the geometry, any change in the model is updated in the measurements.

Not bad, right?

Well, the third rewards are even better

This systems allows multiple people to collaborate, at the same time, in the same file. Locally in the study or remotely.

The relationship, for example, with Engineering, is more efficient. There are fewer surprises. Everything has to square.

Construction companies, at the time of bidding, will have a more reliable document: plans and measurements match, there will be no mismatches.

Although perhaps it is something risky, the BIM model will also be present in the execution process of the work.

Next week I will talk about the two main alternatives: ALLPLAN y REVIT.

Until then, I leave this link to the  theBIMshop, page where you will find much information about BIM (books, magazines, courses, videos, …)
