Step-by-step guide to using BIM on projects
This step-by-step guide explains how Level 2 building information modelling (BIM) can be used for the development of a built asset such as a new building.
BIM Level 2 involves developing building information in a collaborative 3D environment with data attached, but created in separate discipline models.It is required as a minimum on centrally-procured public projects in the UK and is commonly used on private-sector projects.
This guide is written for use by people who are not BIM experts and will be helpful for employers, consultants, contractors and suppliers. To help understand BIM, a glossary of BIM terminology is provided along with a wide selection of supporting articles.
Projects that incorporate Level 2 BIM identify the decisions that will need to be made throughout the life of a built asset and the information deliverables required at each stage of the project to support those decisions. This ensures that appropriate information is created and shared in a suitable format at the right time so that better decisions can be made throughout the delivery and operation of built assets.
Information deliverables include model files, documents and structured data files containing information about the facility, floors, spaces, systems and components. Together these create a digital replica of the built asset that starts by representing design intent and matures by the time handover occurs to reflect what has actually been built and installed.
The guide shows how Level 2 BIM can be incorporated into a project following the RIBA plan of work 2013 stages. The first two stages have been broken down into sub-sections where important employer decisions have been identified that are not included within the RIBA plan of work.
The end of each stage is marked by an employer’s decision point, or gateway, at which the employer needs specific information to help them decide whether the project has developed satisfactorily and whether it should continue to the next stage.
The guide is aligned to PAS 1192-2, the standard for Level 2 BIM in the capital/delivery phase of construction projects and in accordance with the other information management industry standards such as BS1192:2007, BS1192:4 and PAS1192:5.
