BIM for students. Why and how to start?

 

What used to be a transition from 2D to 3D, BIM implementation has become a revolution in AEC building industry. Current trends in the industry should be an important part of any AEC student’s education, and it is crucial to become familiar with software and processes used in nowadays professional life. But how can one learn about BIM if it is not offered in most of the curriculums? This is a problem that we are trying to fix, so if you are a student who is eager to use the newest technology and BIM, continue following BILT Academy and our blog.

Why this topic?

In this blog series, I will try to cover advantages, workflows and implementation strategies that students should use in their school projects to get familiar with the BIM process. The information supplied in this blog is based on knowledge and experience from me, my colleagues, and will feature interviews and quotations from various professionals.

Why to worry about BIM while being a student? There are many advantages to that:

  • Higher chance of getting hired for internships/jobs
  • Helps you produce drawings more efficiently
  • Allows you to access various visualisation and analysis tools
  • Easy collaboration in group work
  • Clash detection
  • Less duplication of work

I have personally used Revit during my bachelor studies and it has helped me reduce drawing production time tremendously. Fast drawing production means more time for studying and… that so-long-needed nap.

What is ‘BIM’?

So now that we know the advantages of using BIM, let’s start with the main question- what is BIM?

Put simply, BIM- Building Information Modelling is a process, used in all AEC fields, starting from construction management spanning to visualisations and facility management. It’s a software application, which brings efficiency and better control of the project through 3D visualisation, data management, simulation and other tools. The National Building Specification released a great and fun visual representation of BIM elements:

BIM means to not only input the information, but to also extract it later on, analyse it, use it during construction and after the handover. During these blog series, we will discuss and elaborate on various aspects and applications of BIM.

Where to start?

There are many ways to learn, however, practice shows to be highly efficient when it comes to software and BIM. First of all, I would highly suggest looking up various blogs, trainings and conference recordings, which are available online. Secondly, try a practical approach- working in groups, ideally multidisciplinary based on school assignments and projects.

Here are links to Autodesk University and Academy, where you can find many videos on BIM, depending on your field of expertise:

You can also watch many videos posted on Youtube from various universities, seminars and conferences.

Refurbishment projects with focus in structural engineering. Visualization of column’s load-bearing capacity

Sometimes it is all about to presenting data in an easily understandable way. Especially when the project hasn’t started yet and you have to present the advantages offered by your office. So my boss came up to me and asked me if I can accomplish a visualization task.
We have a refurbishment project (no digital data available like BIM models, plans,..) and I modeled every column with it’s belonging load-bearing capacity. The load-bearing capacity is the entry of the “comments” property of each object.

column

At first, I thought about to draw isolines of a capacity-surface but it takes too long to compute the surface. I asked Jostein Berger Olsen (http://jbdynamo.blogspot.de/) for his help and he came up with a much smarter idea. He edited my script in a way that circles would be drawn and the properties (like radius and color) depends on the load-bearing capacity. Let’s break down the whole task into some specific subtasks.

  1. Extract all the “comments” data out of each column
  2. As you can see, we have this weird way in Germany to express a decimal digit. Therefore I have to extract the string, erase the last 3 letters (whitespace+”MN”), change the “,” to a “.” and parse the string to a float/double type.
  3. If there is no entry, set the capacity to almost zero.
  4. Creating circles, where the middle points are the middle point of each column and the radius is the capacity of each column.
  5. Create a color range where the range is the normed range of our capacity (use of the Math.RemapRange)
  6. Overwrite the visibility of the circles with the belonging color-range-list.

So that’s it!
Here we have the result:

The python script:

And finally the result:

We are BILT Academy a non-profit organization with a mission to shape the future experts of the building industry. Our aim of this blog is to focus on the technological part of the Architecture, Engineering and Construction fields.

Together with our mother organization BILT and RTC, carefully selected mentors and students, we want to provide you with tips, tricks, workarounds, workflows and latest news, interviews, and last but not least- to answer your questions.

So, what topics will we cover and how often should you check our blog?

Our blog is going to be updated weekly covering these topics:

  • General
  • Architecture
  • Coding, Content and Customisation
  • Computation Design
  • Estimation
  • Model Management
  • Operations and Maintenance
  • Simulation and Analysis
  • Structure
  • Visualisation

Why are we doing it?

We want to ensure that the next generation of professionals have a place to update themselves with technology news and to have a sense of the community they are about to enter.

We would like to invite YOU to be a part of the community!
