LEGO Architecture meets BIM – Part 06: An OPEN BIM data structure

Introduction

This is the 6th in a series of posts about “LEGO Architecture meets BIM”. In the previous posts we have focussed on the geometry of the model for the Villa Savoye building. A Building Information Model (BIM) however also involves the important part of BIM, the ‘I’ which stands for INFORMATION. This is a crucial difference from a model that is simply been built to show a design in 3D.

LEGO Architecture meets BIM – Part 05: Level of Detail (LOD)

Introduction

This blog piece looks at an important concept of Building Information Modelling – Level of Detail (or simply LOD). With both LEGO and construction projects clients will be familiar with what the final constructed ‘building’ looks like. However the final model or building undergoes a series of developments before the design is finalised. This process means that the design can be developed in the most efficient way possible. In very simple terms the more detailed a model is the more time it takes to produce. It also means more time is required to modify more detailed models. Getting the right Level of Detail at the right stage of projects is critical to not introducing waste to the process. Continue reading

LEGO Architecture meets BIM – Part 04: Objects and libraries

Introduction

A building information model is typically constructed using two methodologies. The first is to model using tools designed to construct specific types of elements. For example a Wall tool is used to build a Wall or a Roof tool used to build a Roof. These tools are built-in to most authoring tools. The second methodology is to use objects. Objects can be both static (i.e. they are dimensionally fixed in height, length and width and are fixed in their settings) and parametric (i.e. can be a single object used for various dimensional requirements / settings).

LEGO Architecture meets BIM – Part 03: Visualisation and animation

Introduction

As we saw in the last post we can generate both 2D and 3D views of the models. The 3D model approach offers more than a ‘traditional’ approach as the model can be used to also generate visualisations (some prefer to call these Computer Generated Images (CGI for short) or Renders). Visualisations can be created from a model from any angle with geometry switched on or off as required. Continue reading

LEGO Architecture meets BIM – Part 02: Model views

Introduction

In the previous blog post we showed images of the 3D model we have created of the Villa Savoye from the Lego Architecture series. A 3D model is easy for all parties to understand what the proposed model will look like once ‘built’. However the industry still requires designers to produce ‘traditional’ information including plans, sections and elevations on drawing sheets.  Continue reading

LEGO Architecture meets BIM – Part 01: The 3D model

Introduction

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. Continue reading

Client BIM briefing note: Information Management role

Introduction

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

Filtering elements for IFC 2×3 export from ARCHICAD 18/19

Introduction

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

Exporting quantities to IFC 2×3 from ARCHICAD 18/19 models

Introduction

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

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
