Filtering IFC data in an ARCHICAD 18/19 model

Introduction

One of the challenges faced as we move into this brave new world of information is what information we want users to complete within their models. When you first start looking at data it can be fairly daunting trying to work out what is and isn’t required. Of course we could leave this to individual users but then this creates inconsistencies between individuals, offices and projects. Without creating a standard approach it also makes it harder to set up standardised schedules and provide consistent training. Continue reading

Creating custom IFC properties in ARCHICAD 19

Introduction

Many of the data fields required to transfer data to other parties are already defined in the IFC (ISO 16739:2013) standard with additional properties also prescribed in COBie 2.4 / BS 1192-4:2014. A further 9 standard data fields have also been defined by NBS in the UK in their NBS BIM Object Standard. These 4 standards form the basis for data to be built around an open workflow for projects in the UK. Continue reading

Classification References in ARCHICAD 18/19

Introduction

There are really two types of classification when it comes to working with open standards. The first is how you classify the element/component or a space against the standard IFC (ISO 16739:2013) schema. For example, classifying a model element/component as a Wall.

I have covered the detailed application of Element Classification in a series of detailed posts previously. See our series on Element Classification, of which there are 3 posts, for more information on this subject. However this post deals with a second type of classification which is referred to in IFC terminology as an IfcClassificationReference. Continue reading

Efficient creation of BS 1192:2007+A2:2016 compliant file names from ARCHICAD 19

Introduction

In the last post I talked about the need for organisations in the UK to align their approach with “Level 1 BIM”. One of the requirements is to produce all information with standard file names (BS 1192:2007+A2:2016). Creating BS 1192 compliant file names has to date been a difficult process from ARCHICAD. The process has relied on users manually renaming files once they had dragged their Layout Sheets to the Publisher using ARCHICAD’s Organiser or renaming after publishing the files to a Desktop or Server. Continue reading

Level 1 BIM – the forgotten first step

Introduction

“Level 2 BIM” is the most talked about term in the UK when it comes to BIM and its impact and implications are now being discussed further afield. This challenging goal has been around since 2011 so the UK will have had 5 years to reach that target. Of course this period does also include developing all the standards, protocols and processes that make up “Level 2 BIM”. Continue reading

Producing a Task Information Delivery Plan (TIDP) from ARCHICAD 19

Introduction

One part of the process of “Level 2 BIM” in the UK is for each team member to produce a Task Information Delivery Plan (or TIDP for short). These individual Task Information Delivery Plans are then collated into a single document called a Master Information Delivery Plan (or MIDP for short). In ‘old’ terminology a Task Information Delivery Plan (TIDP) is essentially the equivalent of an Information Release Schedule. Continue reading

Developing a standardised and automated approach to IFC data fields

Introduction

Many users of BIM authoring tools are still focussed on producing the same deliverables they have always produced but in a more efficient way. This means that even if they have adopted an approach to producing data much of it will be focussed on native data fields within their chosen authoring tools. This is fine if the only output is a drawing or a schedule but if others want to use your data for other purposes in a consistent manner on every project, irrelevant of who the model author is, then we believe data needs to be built around a common open standard. Continue reading

IFC 2×3 element and type classification – The plain language A-Z list

Introduction

I’m often asked how to classify certain elements in Graphisoft ARCHICAD for IFC exchange. To many IFC is a weird language that has little to do with everyday language. Many of our classifications are preset up in our ARCHICAD templates but there are always instances where a user needs to manually classify an element. So we thought it would be useful to develop a list to assist model authors understand how to classify model elements against the IFC schema. In fact i’ve been meaning to do this for a long time. Of course in the spirit of OPEN BIM we also decided to share this list. Continue reading

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

Introduction

This is the final part of Element Classification in ARCHICAD. Now this post is predominantly put together as a resource for other ARCHICAD users interested in gaining more knowledge around IFC so its not generally something I expect everyone to read top to bottom. Continue reading

Understanding Element Classification for IFC 2×3 exchange in ARCHICAD 19 – Part 2 – ArchiCAD Type and Library Parts

Introduction

In the last post we looked at the relationship between Components/Elements and Types when using Element Classification.

In this second post we share information about how these Element Classifications are setup by default in ARCHICAD. We will cover how these are set up for elements (i.e. walls, slabs etc) and how they are configured with the out-of-the-box ARCHICAD library.

At the bottom of the post we share some observations and some perceived minor errors with the out-of-the-box ARCHICAD library. Continue reading
