BIM standards

CAD ​​Addict has published a collection of BIM standards in different cities and countries. In Spain, that I have heard, there are none but my faith is that soon someone posts one. I leave the list published in cad-addict.com

Contry Wide:

  • Finland: Common BIM Requirements 2012(published March 2012)
  • United Kingdom: AEC (UK) BIM Protocol v2.0 (published September 2012)
  • Australia: National Guidelines for Digital Modelling
  • United States: National BIM Standard – Version 2 (Published May 2012) (need to login to access the PDF)
  • Singapore: Singapore BIM Guide

Other Public and Local Administrations:

Higher Education Institutions:

Architects’ Boards and Associations:

The same way as CAD Addict I ​​encourage you to tell us if you find any other standard. I hope this compilation will be usefull to develop a Spanish BIM Standard.

Checking the transmittance of the walls

Despite preconceived confidence when working with Autodesk software, is good from time to time make some little comparison exercise software to see if you have similar values. In this case, related to the calculation of thermal loads, I wanted to see if the transmittance of the walls which facilitates the Autodesk wiki with documents, is the same with Design Builder.

The Wall is the chosen “standard wall construction B”

 

I created the same wall with Design Builder:

 

The comparative results are almost identical, as is obtained with Revit 0.2993 W (m² x º K) and 0.300 W Design one (m² x K).

Forcing Yes/No parameter with If formula

[Google translate]

I could say that is a great find but the truth is that the information that follows is a derivation of other articles published on other blogs, wiki’s or websites.

Sometimes we are forced to use parameters of type Yes / No in creating Revit families is MEP, Architecture or Structure and control of this parameter via a formula is not entirely intuitive.

When we are in the situation of having to force the value of this parameter to True or False using a formula first tried putting a “= 1” or “= true” for true and “= 0” or “= false” to false but this does not work. There are several sites where they explain that these parameters obey the logic formulas as 1> 2 then this value will be True or 1 = 0 for a false value. The site that I like is the Revitforum.org for examples of using these formulas, the sloarch.com like revitforum.org has practical examples and moreover is the Autodesk WikiHelp introduces us to the formulas available but with few examples.

In this article we take the opportunity to show you how to make a control parameter forcing parameter value Yes / No If with formulas and logical relationships.

Building service

In making the calculation of thermal loads, Revit gives us the option to choose the air conditioning system to be used to condition the building. What we must choose from the drop down menu does not offer, in this way, and from studies in a building type, a calculation Revit tighter as the HVAC system.

First meeting of Catalonia BIM users group

Translated with google!

Yes! After more than a year online, this group has rised from nothing with an unexpected participation. On Friday 18 took place the first meeting of the group linkedin Catalonia Revit User Group, which follows the proposal by Miquel Rodríguez seeing the group closest to Barcelona was the GURV (Valencia) and hindered participation in their meetings.

As every beginning of the year we set goals and in 2013 played a community networking contruit about BIM in the city. I mention Revit User Group and I referred to as BIM User Group. At this meeting it became clear that the room had not only managed the Revit professionals, had Allplan users, Robot and other programs that in one way or another can be considered small fragments generated model to help us create our BIM model therefore it was decided to rename BIM User Group Catalonia.

As this group gear I thank those who have come to share their experience both as those who are taking the first steps listening technical discussions among the seniors. I also encourage that you sign up to the next meeting on 22.02.2012 at 16.00-18.00h Barcelona

Sliver space tolerance, definition and example

This post is a continuation of the first post on the parameter “sliver space” where explicava for serving. I’ll give the definition (in my view) and attach a video where an exercise to understand it better.

Definition: width exceeding a dead space from which it will consider revit as added to a volume larger contiguous space.

The following is an exercise video with this parameter:
