Understanding Element Classification for IFC 2×3 exchange in ARCHICAD 18/19 – Part 1 – Relationships

August 10, 2015. By

Introduction

In an earlier post we looked at the requirements of COBie for both Components and Types. This series of posts are highly technical posts and not something I would expect users to understand in depth, although I know some of our power users will try and follow them. However this kind of understanding is important if you are setting up templates for ARCHICAD users. There is a fair bit of detail to understand so the information is split into three posts. We will look at the relationship between Components and Types in this post. Continue reading

Interoperability testing: IFC 2×3 site geometry exchange

March 16, 2015. By

Introduction

In the previous blog post we looked at a case study of our Cleveland Fire Brigade Training and Administration Building. An issue that emerged from this project was to do with how our site geometry was being exchanged into Solibri Model Checker. We quickly found a solution to resolve the issue into Solibri. However, sometimes finding a solution to one problem can result in unexpected results elsewhere. Continue reading

openBIM for Facilities Management

November 7, 2014. By

Introduction

The UK Government has defined 3 deliverables for publicly procured projects from April 1st 2016. These are PDF, native models and COBie (see diagram below). PAS 1192-2:2013 sets out the process for the production of these deliverables. Key to PAS 1192-2 is an Employers Information Requirement (EIR) which sets out a clients requirements for projects. Here begins the problem!

ARCHICAD 18: Join the IFC and COBie flow – Part 3 – Model export

October 17, 2014. By

In this final piece in this series about some of the main improvements to IFC and COBie workflow (there are more of course around openBIM) we will look at the enhancements that have been made to geometry export settings. (This piece is primarily focussed on IFC but in time I can see how these changes will also benefit COBie workflows, particularly with regard to the Assembly Worksheet). The new features might be missed by some users but these changes really are going to have a significant impact on the quality of the models we export to others. Continue reading

ARCHICAD 18: Join the IFC and COBie flow – Part 2 – Data mapping

September 22, 2014. By

In the last post we looked at Project Info which briefly mentioned data mapping to IFC fields. In this post we will specifically look at the IFC data mapping in ARCHICAD 18. Whilst there are some great features in the latest version of ARCHICAD, the IFC mapping is definitely my personal favourite new feature. For me, this is real BIM! Rendering is always high on architects wish lists and grabbed a lot of the headlines. However the need to create, manage and check data efficiently is imperative for us as we move towards the UK Government target of achieving “Level 2 BIM’ by 2016. Continue reading

ARCHICAD 18: Join the IFC and COBie flow – Part 1 – Project Info

September 5, 2014. By

The latest version of Graphisoft ARCHICAD was released earlier in the summer and whilst all the headlines will go to the big features like rendering and revision management there are new features which for workflows utilising IFC and COBie are really great improvements. To many these changes in ARCHICAD 18 will not be abundantly clear to the average user. However these changes will allow data to become more utilised even to those who don’t understand IFC or COBie particularly well. This blog piece is going to focus on the changes to the ‘Project Info’ dialogue box, although subsequent pieces will look at further changes. Continue reading

Why use IFC?

February 3, 2014. By

Following my last detailed and highly technical post about model creation related to IFC, I received a comment on the blog piece from fellow Graphisoft ARCHICAD user and expert, Link Ellis from ArchiLINK. Link was seeking more of an overview to how IFC works for his clients. I think its fair to say that many people would like this, including me. Unfortunately I am not aware of any document that tackles this at present. It is something I have raised and we have discussed at buildingSMART UK Technical Group meetings. Hopefully this will become available in due course. In the meantime I will continue to share my IFC understanding (particularly related to ARCHICAD) and thoughts through this blog. Continue reading

Practical application of IFC & COBie: Model Creation

January 28, 2014. By

“Criticism comes easier than craftsmanship” Zeuxis (approx. 400BC)

For those of you who don’t know me too well, I am somewhat obsessed with IFC, or at least obsessed with working out facts from fiction with IFC exchange. Simply stating “IFC doesn’t work, therefore I refuse to use it” is boring and fundamentally unhelpful. It’s like saying “my phone lost reception so I am never using a phone again”. It’s also too easy to believe certain software companies aren’t interested in improving their IFC implementation. Come on, we can all do better than that. Nothing is perfect and that includes all authoring tools without exception and I am not going to pretend IFC is perfect either, it is far from it. Yet I know that it is perfectly usable for our live projects. Continue reading
