Building Information Modelling (BIM) is a process that involves creating and using an intelligent 3D model to inform and communicate whilst in the design phase of a project and manage an asset throughout its lifecycle. Design, visualisation, simulation and collaboration enabled CAD BIM solutions to provide greater clarity for all stakeholders across the project lifecycle. BIM makes it easier to achieve project and business goals. It increases efficiency across from the design and throughout the lifecycle of building.
PLEASE FIND BELOW BIM SERVICES PROVIDED BY AMC:
LEVEL 0 - UNMANAGED 2D CAD
- In its simplest form, BIM level 0 effectively means no collaboration.
- 2D CAD drafting only is utilised, mainly for Production Information.
- Output and distribution is via paper or electronic prints, or a mixture of both.
- Basic study work.
LEVEL 1 - MANAGED 2D AND 3D (MIXTURE)
- This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information.
- Common standard would be used for the design and electronic sharing of data is carried out from a common data environment (CDE), AMC uses NavisWorks.
- BIM Level ‘1’ is the level at which many organisations are currently operating, although there is no collaboration between different disciplines – each publishes and maintains its own data.
LEVEL 2 - MANAGED 3D (MIXTURE)
- BIM Level ‘2’ is distinguished by collaborative working – all parties use their own 3D CAD models, but not necessarily working on a single, shared model.
- Collaboration comes in the form of how the information is exchanged between different parties which in AMC case is NavisWorks – and is the crucial aspect of this level.
- Design information is shared through a common file format (NWF and NWD), which enables any organisation to be able to combine that data with their own in order to make a federated / Composite BIM model, and to carry out interrogative checks on it.
- NavisWorks supports and combines any CAD software on a project and allows all parties to review and input.
LEVEL 3 - FULLY INTEGRATED 3D ENVIRONMENT
- BIM Level ‘3’ is a the full BIM service and represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralised repository. All parties can access and modify that same model, and the benefit is that it removes the final layer of risk for conflicting information - this is known as ‘Open BIM’.
- AMC offer this to our clients as a service, however this is dependable on the entire project including the various companies agreeing to use software on same platform or 100% compatible.
LEVEL 4 - 4D TIMELINING
- BIM Level ‘4’ is 4D Timelining. Essentially this is the synchronisation of the plan / program of works and the 3D model.
- From a visual perspective the model / build order can be seen inline with the timeline / program of works. This can assist the construction team visualise the build sequence and highlight any issues.
- Progress made in the model throughout the design stage can be visually demonstrated and more easily understood by the project team.
- Timelining and construction sequencing.
LEVEL 5 - COST AND MATERIAL TAKE -OFFS
- Traditional manual material ‘take-offs’ are in accurate.
- Material take-off’s can be exported automatically from the 3D model. This represents a huge time saving.
- These take-offs can then be used to generate costs, productivity and manpower projections.
- Utilised for live projects and estimation purposes.
LEVEL 6 - FULL BIM
- Complete ‘As built’ record for the owner.
- Full data comprising of all information normally included in the operation and maintenance (O&M) manuals and warranty information.
- Useful for future maintenance and upgrades.
- Data stored in a central location.
- On going cost of maintenance for the building reduced.
- Utilise model for the lifecycle of the building - Lifecycle management.
