BIM Levels

BIM revolution is very widespread in the construction industry. When we talk about BIM maturity levels and dimensions, we are primarily talking about the supply chain’s ability to interchange information digitally. The maturity levels from Level 0, through Levels 1, 2, 3, and beyond are often envisioned via the maturity ‘wedge’ diagram conceived by Mark Bew and Mervyn Richards. BIM dimensions refer to the specific way in which distinct kinds of data are linked to an information model. By adding additional dimensions of data, you can start to get a better understanding of your construction project – how it will be delivered, what it will cost and how it should be maintained etc. These dimensions – 4D, 5D and 6D BIM – can all feasibly (but not necessarily) occur within a BIM Level 2 workflow.   BIM Levels and Dimensions explained Today’s BIM technology provides more than 3D CAD  modeling and comes with augmented BIM models or BIM dimensions allowing to compute the 4th dimension of time, 5th dimension of cost 6th dimension of Project life-cycle Information often called facilities management. As a project progresses through different phases, the level of development in a BIM model also increases to different levels namely LOD (Level of Detail) 100, 200, 300, and beyond. BIM Maturity Levels   BIM LEVEL 0  The most simplistic form of BIM level is LEVEL 0, it effectively means no collaboration. Only 2D CAD drafting is utilized, mainly for Production Information (RIBA Plan of Work 2013 stage 4). Output and administration are via paper or electronic prints, or a mixture of both. The majority of the industry is already well ahead of this now. BIM LEVEL 1  This typically incorporates a blend of 3D CAD for concept work, and 2D for drafting of sanctioned documentation and Production Information. CAD standards are managed to BS 1192:2007, and digital distribution of data is carried out from a common data environment (CDE), often managed by the constructor.   BIM LEVEL 2  Level 2 BIM is characterized by collaboration and demands “an information exchange process which is specific to that project and coordinated between various systems and stakeholders”. Any CAD software that each party uses 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).   BIM LEVEL 3 A single, collaborative, online, 3D project model including all building information such as construction sequencing, cost and lifecycle management information. Level 3 has not yet been fully determined, however the vision for this is outlined to follow ‘key measures’ to be secured such as: Designing a set of new, international ‘Open Data’ standards which would pave the way for easy sharing of data across the entire market The establishment of a new contractual framework for projects which have been procured with BIM to ensure consistency, avoid confusion and encourage, open, collaborative working. The creation of a cultural environment that is co-operative seeks to learn and share. Training the public sector client in the use of BIM techniques such as data requirements, operational methods, and contractual processes. Driving domestic and international growth and jobs in technology and construction.   Bridging the gap between Detailing and Modeling   1D 2D 3D 4D 5D and 6D BIM Dimensions explained Engineering drawings start from a scratch point of concept design and move forward with a 2D CAD design drawings dimension, these require an x-axis and y-axis to create the CAD drawings. CAD software are used to generate technical design drawings for floor plans, landscapes, permit drawings, building inspection plans etc. Transformation from 2D CAD to BIM allows better conceptualization and efficient building/facility designs. 3D BIM Dimension The third dimension of BIM is the shared information Model that adds a third z-axis to existing x and y axis. The 3D BIM incorporates the process of creating graphical and non-graphical information and sharing this information in a Common Data Environment (CDE). 3D BIM enables the stakeholders to manage and collaborate efficiently in modeling and analyzing complex anatomical problems. As the project life cycle progresses this information becomes richer in detail until the point at which the project data is handed over to the owner/user at completion. 4D BIM Dimension The fourth dimension of BIM has the element of time added o the model and is also called Construction sequencing or scheduling. Time-related data for a specific component may include data for lead time, how long it requires to install/construct, the time expected to get operational/solidify/fix, the grouping where components ought to be installed, and dependencies on different areas of the project. Opting 4D BIM enables improves clash free construction scheduling and provides the right strategy for construction management and optimization. 5D BIM Dimension The fifth dimension of BIM adopts and applies the element of cost to the model to deduce accurate cost information. A data model is probably going to contain three sorts of Quantities. Quantity dependent on genuine model components (with noticeable details) which you can investigate through the model are the most self-evident. Amounts may likewise be gotten from model segments (like moldings around windows) that aren’t generally noticeable. The third sort of amount is non-displayed amounts (these incorporate temporary work, construction joints and so forth) Unless the development stage is demonstrated then the design model will show, graphically, design quantities yet not the construction quantities. A cost estimator is probably going to be skilled in getting the amounts that aren’t exclusively founded on model components. Due to the involvement of surveyors and cost estimators from the early stage of the project BIM modelers along with the design teams have steady information with the help of cloud computing. This leads to better cost and design estimations with BOQ/BOM (bill of quantities/materials) 6D BIM Dimension The 6D BIM model is also called Project lifecycle information or Facilities management or integrated BIM or iBIM. 6D BIM involves the inclusion of information to support project life cycle management and operation to drive better business outcomes. This information might include information on the manufacturer
