Dynamo-Vasari-Green Building-Infraworks workflow

I've been quiet lately and it's because I started using a couple of new softwares/tools :

"Autodesk® Vasari is an easy-to-use, expressive design tool for creating building concepts. Vasari goes further, with integrated analysis for energy and carbon, providing design insight where the most important design decisions are made. And, when it’s time to move the design to production, simply bring your Vasari design data into the Autodesk® Revit® platform for BIM, ensuring clear execution of design intent.

Vasari is focused on conceptual building design using both geometric and parametric modeling. It supports performance-based design via integrated energy modeling and analysis features. "


Green Building Studio

"Autodesk® Green Building Studio® energy-analysis software enables architects and designers to perform whole-building analysis, optimize energy consumption, and work toward carbon-neutral building designs earlier in the process. Cloud-based energy-efficiency software helps teams achieve sustainable building designs faster and more accurately with powerful energy- and carbon-analysis tools."



"Dynamo is a visual programming environment for Building Information Modeling.

Dynamo extends the parametric capabilities of Revit and Vasari with the data and logic environment of a graphical algorithm editor.

Dynamo is an open source project for developers and designers to become actively involved in building the tool."



Quickly generate 3D models to create infrastructure designs and proposals in the context of the built environment with InfraWorks™ software (formerly Autodesk® Infrastructure Modeler). Accelerate the design process, and streamline decision making. Rapidly generate data-rich proposals to better predict how design alternatives may perform in the existing environment, and more effectively communicate with stakeholders.


So what all these guys have in common ? Well, if you're an architect using BIM tools for conceptual building studies you probably have all these softwares in your toolbox. More coming soon stay tuned !

Why LOD improve communication in my team ?

There is this big buzz right now in the BIM industry with level of detail and level of development (LOD) of building information models. You can see in a number of places discussions or documents about LOD.

What makes BIM successful ? Some says it is the skills of the team and I think this is true but skills without workflow documentation is like baseball without rules. If your company wants to play BIM, well you need to set the rules first. Below I share my thoughts about reasons why using LOD.

1.LOD as a common language
The purpose of building a contract is to set the liability level, project scope and delivery methods that parties have agreed upon. Level of detail can help define a common language that helps people expressing their expectations. We should see LODetails as definitions of objects complexity in a building information model. They are a few definitions (LOD100, LOD200, LOD300, etc) in the BIM dictionary that everyone use to make communication easier.

2.LOD as a scope
My building information model is better than yours. Very often I  see peoples not adding enough information in their model or too much considering the goal of the project. LOD make scope definition easier. This should always be defined in the BxP (Bim execution plan) to make sure everybody knows the level of development required at each phase of the project from early conceptual design to building operation. Each deliverable should have its own LOD specification so you can clearly understand the container and its content.

3.LOD as a progress benchmark
Defining what is the difference between what was planned vs what is delivered at a specific stage of the project is easier with LOD. Many BIM software provide features such as color display base on filters and values. Let"s think about a system where the user input the progress of objects in their properties so you can see the progress of the project in a color coded view. This is very useful during coordination meetings to demonstrate level of reliability of objects.

4.LOD as a standard for content generation.
Defining content development standards in your company is the number 1 thing to do if you want to make BIM a success story. LOD is helping content creators to standardize the way they work. This ensures a uniform project documentation output but also a better user experience due to uniformity.

Finally, you should sit with your team and agree on LOD definitions. I suggest you start with the document from bimforum which is a very good starter kit and modify it to suit your needs.
