![]() Level 2 BIM: Teams work in their own 3D models Many firms are at Level 1 BIM, which doesn’t involve much collaboration, and each stakeholder publishes and manages their own data. At this level, CAD standards are managed to the standard of BS 1192:2007, and electronic sharing of data carried out from a common data environment (CDE) usually managed by the contractor. Using 3D CAD for concept work, but 2D for drafting production information and other documentation, probably means you're working Level 1 BIM. Level 1 BIM: 2D construction drawings + some 3D modeling Today, most of the industry is working above this level, although not every professional in the industry has sufficient BIM training and some projects do not include the use of BIM in contract specifications. If you’re using 2D CAD and working with drawings and/or digital prints, you can safely say you’re at level 0. Level 0 BIM refers to not operating collaboratively at all. Level 0 BIM: Paper-based drawings + zero collaboration So what does each level involve, and how can you identify which at which level you’re working? Below are brief descriptions of the first three levels and an explanation of what criteria is involved at each stage. The purpose of these levels is to gauge how effectively, or how much information is being shared and managed throughout the entire process. Each level represents a different set of criteria that demonstrates a particular level of ‘maturity.’ BIM levels start with 0 and go to 4D, 5D, and even 6D BIM. Now that we’ve covered what BIM is and how it can be used, let’s move on to BIM levels.ĭifferent levels of BIM can be achieved for various types of projects. ![]() Information models can be used at all stages of a building’s life from inception to operation- and even renovations and renewals. This information in a BIM model is shared through a mutually accessible online space known as a common data environment (CDE), and the data collected is referred to as an 'information model'. The data can be used to improve accuracy, express design intent from the office to the field, improve knowledge transfer from stakeholder to stakeholder, reduce change orders and field coordination problems, and provide insight into existing buildings for renovation projects later on. ![]() All of the information gathered- from conception to completion- isn’t just stored, it’s actionable. However, the true power of BIM lives in the “I” (information). The “I” in BIMīIM, as a whole, refers to the process of all parties involved in the construction and lifecycle management of built assets, working collaboratively and sharing data. This allows the model to remain consistent and coordinated throughout the entire process so that structural engineers, architects, MEP engineers, designers, project managers, and contractors can work in a more collaborative environment.Įxample of a BIM object: Optibal W6 ball valve with Actuator - downloaded from the manufacturer and used by plumbing engineers in their BIM models. If any element is changed, BIM software updates the model to reflect that change. BIM ObjectsīIM objects, the components that make up a BIM model, are intelligent, have geometry, and store data. Now, BIM (Building Information Modeling) is the standard- but it is much more than just a 3D model. Later on, CAD turned 3D, which brought more realistic visuals to blueprints. Next came CAD (Computer Aided Design), which helped drafters see the benefit of plans in a digital environment. This 2D approach made it very difficult to visualize dimensions and requirements. In the past, blueprints and drawings were used to express information about a particular building plan. This data allows governments, municipalities, and property managers to make informed decisions based on information derived from the model- even after the building is constructed. It can also span into the operation and management of buildings using data that building or structure owners have access to (hence the Building Information Management). Using a level 3 BIM model for digital clash detection- one of the primary uses cases for BIM. It is a highly collaborative process that allows architects, engineers, real estate developers, contractors, manufacturers, and other construction professionals to plan, design, and construct a structure or building within one 3D model. Read on to discover what BIM is, how BIM is used, and what BIM levels mean.īIM is an acronym for Building Information Modeling or Building Information Management. ![]() BIM model of Randselva Bridge, the world's longest bridge built with BIM models only - no drawings.Īcross the world, BIM (Building Information Modeling) is a crucial and even mandated process to ensure the planning, design, and construction of buildings is highly efficient and collaborative.
