The implementation of BIM Level 2 on Government projects means that all public building projects will only be given to firms that have embrace the process.
We have written a five-part series to explain the change that BIM will bring and how to prepare your practice implementation for this. A quick overview of what these posts are about can be seen below:
Applying BIM will bring about savings in the region of 16-20% in the cost of design and build by improving the efficiency of the construction process. Subsequently to bring similar savings to the maintenance and running of said construction, which is said to represent up to 80% of the lifetime cost of the said building.
The second benefit is the acquisition of information – the ‘I’ in BIM – that can be shared by all members of a construction project in enhanced collaboration in a CDE – Common Data Environment.
BIM, however, is not just about design and construction, nor is it just about total lifecycle building management, it is a valid process for sharing a building model for environmental studies, or for handling structural analyses.
After the start of April 2016, therefore, any company proposing to deliver a public building project must demonstrate that it is BIM capable, and can deliver Level 2 information to its clients during the design and construction phase, and subsequent to the completion of the construction phase and handover of the building or asset.
Information should be made available in BIM Level 2 in three key formats. The first, of course, is the actual 3D Building Model. The second is the complete range of 2D drawings and reviewable design deliverables derived from the 3D model, which are used in conjunction with the third, and target format – COBie data files.
COBie is one of the elements of BS 1192-4:2014, which defines the methodology for the transfer of structured information between parties relating to both building and infrastructure assets.
It will replace the impractical extraction of information from a 2D drawing – i.e., maintenance engineers selecting pre-printed drawings from a shelf full of files – and deliver asset information, such as spaces (the location of equipment), the scheduled equipment and products that appear in them, in a simpler, more efficient manner
If you are designing in 3D, and creating 3D models, you are already collecting the sort of information you will need to satisfy BIM requirements.
Training is an emotive issue. You need to train up your staff so that when you start your first live BIM project, they are ‘up to scratch’ and not having to learn on the job.
Graphisoft has been a front runner for BIM since it launched ARCHICAD, the first BIM software for architects, and continues to lead by introducing innovative solutions, such as BIMcloud. This is the world’s first real-time BIM collaboration environment, and the BIM-integrated Green design solution, EcoDesigner Star and BIMx, a leading mobile app for BIM visualisation.
