Trying to explain Building Information Modelling (BIM) to a layperson can often be quite difficult without descending into loads of technical detail and a whole host of acronyms. Many of our clients are only involved once in the design and construction process. Some clients of course have much more exposure to multiple projects and ultimately these clients will drive BIM forward as they see the issues that cause them issues over and over again. Repeating the process allows them to understand why a different approach will produce better outcomes for their assets but for the one time only clients they only get one shot. Of course with all projects we want the best outcomes whether a client builds once or multiple times. So for us it is important clients understand the benefits that a BIM approach can bring.

Over the past 12 months we have seen a number of our client’s set out that they wish the design team to deliver “BIM Level 2”. Whilst this is great to see an increased interest in the need for BIM, many clients are missing a crucial aspect of a “BIM Level 2” project. This is the need to appoint someone to carry out Information Management for the project. Continue reading

There are a number of things to understand when exporting an IFC model. What is often misunderstood is that an IFC file is not simply one file. IFC files are exported for different purposes so when issuing an IFC file it is important to understand the purpose of the exchange. Once you understand the needs of the recipient you can begin to filter your model for different uses. Continue reading

Over the past few years we have slowly been finessing our approach to data for our architectural models. The models produced by project teams are now progressing to a point where cost consultants and main contractors are seeing the opportunity to use our models to assist them to produce a detailed cost breakdown of a project. In order to produce these cost plans we need to be able to provide a well built model from both a geometry and data point of view. If we build our models correctly then we should be able to use our approach to produce the required quantities that can then be used for quantification and in turn costing. Continue reading

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

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

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

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 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

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
