LEGO Architecture meets BIM – Part 12: Federated Models

Introduction

Up to this point in the series on ‘LEGO Architecture meets BIM’ we have only discussed a single model. However on real life projects models are split into a number of models. This is normally split by discipline (architectural model, services design model, structures model etc), due to file size or simply to provide easier management of files during the project (for example to provide a simple method to switch off models quickly). We also split models because it assists with model checking but more of this in another post. Continue reading

LEGO Architecture meets BIM – Part 11: Geometry exchange

Introduction

Models are often exchanged between different stakeholders working on projects. Model authors and those using the models use a variety of software for their own needs. In order for BIM to work it is imperative that geometry and information are exchanged reliably between each software tool. Continue reading

LEGO Architecture meets BIM – Part 10: Free desktop model viewing

Introduction

We have seen in previous posts specific views of the model. However one difference with a 2D approach is being able to share models with others so that they can view the model geometry and/or data without needing any authoring tools themselves. Continue reading

LEGO Architecture meets BIM – Part 09: Schedules

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

LEGO Architecture meets BIM – Part 08: Augmented Reality

Introduction

In the last post on this series on LEGO Architecture meets BIM we looked at how information can be displayed on drawings. In this post we look at how we can use Augmented Reality (AR for short) to view both the geometry of the model and also data. Continue reading

LEGO Architecture meets BIM – Part 07: Data display on drawings

Introduction

As we have seen in the previous post we can add data to 3D models to create Building Information Models (BIM). This data is embedded in various locations within the model. These for example are Project, Site, Building, Floor (Building Storey), Space, Zone, Component/Element, Type and System. We will see in other posts how we can access this data in the model for various uses by a variety of parties. However, in this post we will focus on how this DATA can be extracted for use in traditional drawing outputs. This data becomes INFORMATION to the reader of the drawing. Continue reading

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. Continue reading

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
