Christmas 2014

The Customer Centre will be closed from 12.30 on Wednesday 24 December 2014 until 9.00 on Monday 5 January 2015. During this period we are unable to provide telephone support.

In the meantime you can access a wealth of online CPD at www.ribacpd.com and you can book a place on a CPD Roadshow by visiting www.architecture.com/whatson

We wish all our customers a very Merry Christmas and a Happy New Year!

Introduction

In its most basic form BIM (or Building Information Modelling) is a way of managing all the information required in a building project. It is an expanding, and increasingly important topic which depends upon a large amount of technical information and building data.

Since 2016, the Government have required all public procured construction projects to be built using BIM, calling for the adoption of Level 2 BIM within the design and build process. BIM is growing (and will continue to do so) and the integration of data and project interoperability are becoming increasingly important as the construction industry moves forward. BIM cannot, and should not, be ignored and adopting it sooner rather than later is key to progress. It is an ever evolving model that will have a huge positive impact on the design, construction and maintenance of buildings.

In this CPD we will be looking at what BIM is, the different formats used and how it has developed, as well as discussing some of the advantages of using modelling as part of a construction project.

1.0 What is BIM?

BIM involves modelling all the components that make up the building through the documentation of non-graphical and graphical information that will define the delivered project. This is done through the Project Information Model (PIM). Upon completion of the build, the Asset Information Model (AIM) comes into being. This is a knowledge resource that provides continually maintained information about the building throughout its lifecycle to demolition.

The building can be modelled not just geometrically but also in terms of performance, time and costs. This gives an accurate representation of the building’s development in a virtual form, and data about the building’s performance throughout its lifecycle. The level of information available can vary depending on the level of maturity of the data provided by the manufacturer of the product, or by the designer, so some parts of the model may be more detailed than others.

The data about each product that makes up the building project is made available by the manufacturer. The data is the main component of the product ‘Object’. This is a 3D model of the product, containing important and relevant data to be used in the building model. For example geometric data such as standard board size and thickness, technical data such as thermal resistivity and water vapour transmission, and other chosen data such as GWP and Green Guide Rating.

This data can then be used in 3D CAD modelling packages (such as Revit, ArchiCAD, Vectorworks and AECOsim) to create designs for building projects, performance analysis for the proposed design, and information for regulatory approval and construction. The end result is a model which shows the project from the initial concept, through the design stage to construction and end use. The model will directly reflect what has been built and can be used by anyone involved in the project. It will form the basis for other documents which are required when the building is occupied, such as health and safety information and it will provide data for ongoing maintenance.

The Government is supporting the BIM model and, following on from their ‘Construction Industry Strategy 2011’ has mandated that all public procured construction projects from 2016 onwards should use BIM.
