Testing openBIM data exchange for client specific data sets

July 24, 2018. By

Introduction

As many of you who read this blog regularly know, Bond Bryan Digital promote open standards wherever possible to exchange information between different project stakeholders. The primary methods of exchange we utilise on our projects are PDF, XLSX, IFC, COBie and BCF (and DWG if we really have to!). Many are still sceptical about information exchange using certain formats. This is particularly true of IFC (Industry Foundation Classes) which is described by ISO16739:2013. The truth though is that the IFC schema is not really to blame. The issue is that the exchange is often poor because of either poor implementation of the schema by vendors or poor implementation by users. Continue reading

LEGO Architecture meets BIM – Part 09: Schedules

July 28, 2016. By

Introduction

As designers we are often required to provide data in a schedule format. This is either provided directly on a layout sheet as a PDF, as an excel output or as a model for schedules to be setup and utilised in external tools. I believe this final workflow will become more and more common place as BIM evolves.  Continue reading

Filtering IFC data in an ARCHICAD 18/19 model

January 22, 2016. By

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

January 8, 2016. By

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

December 4, 2015. By

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

Developing a standardised and automated approach to IFC data fields

October 2, 2015. By

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.
