Bim overview
1) Building Information Modeling (BIM) is a process that generates and manages building data throughout the lifecycle of a construction project using 3D modeling software. 2) BIM allows all project stakeholders to visualize, simulate, and coordinate designs in real-time, improving productivity in design and construction. 3) BIM provides greater project insight through analysis of costs, schedules, and constructability which enables prompt response to changes and more efficient processes.

Level 1 BIM Managed CAD,with the increasing introduction of spatial coordination, standardised structures and formats as it moves towards Level 2 BIM Level 2 BIM Managed 3D environment with data attached, but created in separate discipline-based models Level 3 BIM A single collaborative, online, project model with construction sequencing (4D), cost (5D) and project lifecycle information (6D). This is sometimes referred to as ‘iBIM’ (integratedBIM) 15
- 16. LOD, as in"Level of Development", is a measure of how seriously you take the information represented by a BIM element. It is not necessarily a measure of the amount of information, although obviously there must be enough information to satisfy the LOD level. It is also not a measure of the amount or accuracy of graphical information. The appearance of a BIM element is only one piece of information about that object, and usually the least important. A contractor doesn't need to know what a desk looks like to order it, nor to place it in the building. But they do need to know what the manufacturer and model number is. Others may need to know its dimensions to coordinate with things around it, but they too do not necessarily need to know what it exactly looks like. Or in general terms: LOD 100 = there is a thing LOD 200 = there is a thing about this size LOD 300 = there is a thing with these functions and options LOD 400 = it is this particular thing. LOD 500 = this particular thing provided by this person on this date. 16
- 17. LOD levels fora chair might go: LOD 100 = there is a chair LOD 200 = there is a chair that has nominal space requirement of 500x500 LOD 300 = there is a chair with arm rests and wheels LOD 400 = manufacturer and model number. LOD 500 = manufacturer and model number, supplier, date purchased. 17
- 18. LOD is sometimesinterpreted as Level of Detail rather than Level of Development. This Specification uses the concept of Levels of Development. There are important differences. Level of Detail is essentially how much detail is included in the model element. Level of Development is the degree to which the element’s geometry and attached information has been thought through – the degree to which project team members may rely on the information when using the model. In essence, Level of Detail can be thought of as input to the element, while Level of Development is reliable output. 18

The use of the term 4D is intended to refer to the fourth dimension: time, i.e. 4D is 3D plus schedule (time). The construction of the 4D models enables the various participants (from architects, designers, contractors to owners) of a construction project, to visualize the entire duration of a series of events and display the progress of construction activities through the lifetime of the project.

The 6D model is usually delivered to the owner, when a construction project is ready to be closed-out. The “As-Built” BIM model is populated with all relevant building component information such as product data and details, maintenance/operation manuals, cut sheet specifications, photos, warranty data, web links to product online sources, manufacturer information and contacts, etc. This information-centric database is made globally accessible to the users/owners through a customized proprietary secure web-based environment.

Editor's Notes
- #4 Building Information Modeling (BIM) is a process that begins with the creation of an intelligent 3D model to capture, explore, and maintain planning, design, construction, and operational data in order to better inform decision making for building and infrastructure projects. The information in the model remains coordinated and consistent an Create and use a data-rich 3D model to improve how buildings and infrastructure are planned, designed, built, and managed. Provides greater project insight on things like cost, schedule, and constructability Share and use the same consistent data whether you’re at your desk or in the field Respond quickly to change with processes that are smarter and faster Model is available for simulation, analysis, collaboration, and communication throughout the lifecycle of the project.

- #16 Level 0 BIM In its simplest form, level 0 effectively means no collaboration. 2D CAD drafting only is utilized, mainly for Production Information (RIBA Plan of Work 2013 stage 4). Output and distribution is via paper or electronic prints, or a mixture of both. The majority of the industry is already well ahead of this now (source: NBS National BIM Report 2014). Level 1 BIM This typically comprises a mixture of 3D CAD for concept work, and 2D for drafting of statutory approval documentation and Production Information. CAD standards are managed to BS 1192:2007, and electronic sharing of data is carried out from a common data environment (CDE), often managed by the contractor. This is the level at which many organizations are currently operating, although there is no collaboration between different disciplines – each publishes and maintains its own data. Level 2 BIM This is distinguished by collaborative working – all parties use their own 3D CAD models, but not necessarily working on a single, shared model. The collaboration comes in the form of how the information is exchanged between different parties – and is the crucial aspect of this level. Design information is shared through a common file format, which enables any organization to be able to combine that data with their own in order to make a federated BIM model, and to carry out interrogative checks on it. Hence any CAD software that each party used must be capable of exporting to one of the common file formats such as IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange). This is the method of working that has been set as a minimum target by the UK government for all work on public-sector work, by 2016. Level 3 BIM Currently seen as the holy grail, this represents full collaboration between all disciplines by means of using a single, shared project model which is held in a centralized 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’. Current nervousness in the industry around issues such as copyright and liability are intended to be resolved – the former by means of robust appointment documents and software originator/read/write permissions, and the latter by shared-risk procurement routes such as partnering. The CIC BIM Protocol makes provision for these. Update - The UK government reasserted its commitment to Level 3 BIM as part of the Budget announced in March 2016. Read more. Looking further ahead, it is highly probable that collaborative working practices will ultimately filter through to the private sector ...

- #68 It’s better for organizations to start slowly with BIM adoption to ensure the best chance of success. Instead of deploying it across the board, a firm should use BIM on just a few handpicked projects, carefully and deliberately, to give team members a taste. If done well, pretty soon everyone wants to be on a BIM project, and expanding BIM across the organization becomes an organic process. In economics, the 'J curve' refers to the trend of a country's trade balance following a devaluation or depreciation under a certain set of assumptions.
