Still wondering what is BIM and the benefit of BIM services?

BIM (building modeling information) is a much-talked-about topic these days in the AEC industry. You may get different definitions of BIM from various sources. While some people say BIM is a type of software, others say it is the 3D virtual model of buildings. According to some experts, it is nothing but collecting and organizing all building data into a structured database. In short, we can say BIM is all the above and sometimes some more. But, in a simple sentence, BIM is the means by which everybody can understand a building through the use of a digital model.

Understanding BIM

BIM is a new way of approaching the design and documentation of construction projects.

• Building: BIM considers the entire life-cycle of the building such as design, build,d and operations
• Information: It includes all information about the building and its life-cycle
• Modeling: BIM defines and stimulates the building, its operation using integrated tools, and its delivery

Understanding the Different Levels of BIM

Building Information Modeling (BIM) is a powerful framework that enhances efficiency in construction projects by enabling better information sharing and management. Each level of BIM represents a certain maturity level in collaboration and data integration, ranging from basic concepts to advanced integrations.

Level 0 BIM: Basic and Isolated

Level 0 BIM is the simplest level, essentially comprising 2D CAD drawings without collaboration. Projects at this stage rely on manual processes with no digital data exchange among stakeholders. It’s a standalone model where digital collaboration doesn’t occur.

Level 1 BIM: Initial Steps in Integration

At Level 1, projects still use 2D CAD primarily but start incorporating some 3D modeling for conceptual work. Projects use a common data environment (CDE) to manage and share information, although collaboration remains minimal. Standards like BS 1192:2007 are often applied, but each stakeholder still manages their own data independently.

Level 2 BIM: Collaborative but Separate Models

Level 2 BIM marks a leap toward collaboration, where teams work on their own 3D models. Although these models are independent, information is shared via standardized file formats like IFC (Industry Foundation Class) or COBie (Construction Operations Building Information Exchange). This approach reduces duplication of effort, saves time, and minimizes costs by improving information exchange.

Level 3 BIM: Unified Project Model

At Level 3, a single, shared project model is used by all team members. This central model promotes enhanced collaboration and minimizes the risk of data clashes, fostering improved project value and efficiency. Known as Open BIM, this level enhances visualization, communication, and understanding of project designs among various teams and trades, reducing the likelihood of rework and revisions.

Advanced BIM Levels: Incorporating Time, Cost, and Sustainability

• Level 4 BIM introduces scheduling into the model, allowing for effective time management across project phases, and facilitating streamlined operations.
• Level 5 BIM adds cost dimensions by integrating budget analysis and cost tracking. This allows for real-time cost assessment, simplifying financial management throughout the project lifecycle.
• Level 6 BIM focuses on sustainability and energy efficiency. This level uses data to predict and manage a building’s energy consumption, enabling the construction of energy-efficient and sustainable structures.

Each of these advanced levels contributes to more efficient and effective project management, from improved planning and cost analysis to sustainability considerations post-construction. By understanding and implementing these levels, organizations can significantly enhance their operational capabilities, driving projects towards success while fostering a sustainable approach.

Understanding Level 0 BIM

Level 0 BIM represents the most basic form of Building Information Modeling (BIM), or rather, the absence of it. This level is characterized by non-collaborative processes. When professionals are working with 2D Computer-Aided Design (CAD) tools and rely on traditional drawings or digital prints, they are operating at this foundational stage.

At this level, information is typically shared on paper or via basic electronic files without any integration or data-sharing practices. This means that different teams or departments may not communicate effectively, leading to potential inconsistencies and inefficiencies in project management.

Key Characteristics of Level 0 BIM:

• Use of 2D CAD: All design and documentation are created in two dimensions, offering no advanced data modeling.
• Independent Work Processes: Teams and individuals operate independently without the benefit of integrated systems.
• Limited Digital Communication: Information exchange occurs through non-interoperable digital formats or physical prints.

While the industry has largely moved on to more collaborative BIM processes, not everyone has the necessary training, and certain projects may still not specify BIM requirements in their contracts. This means that some professionals and companies continue to work within this basic framework, albeit less commonly than before.

Details of BIM Elements

BIM model, if explained in layman’s terms, consists of the virtual equivalents of the actual building parts and pieces that are used to build a building. BIM elements have both the physical and logical characteristics of their real counterparts. In other words, BIM elements are the digital prototype of the physical building elements like columns, windows, walls, doors, and stairs, etc. These elements help us to understand its behavior in a computer environment way before the real construction work starts.
Beyond just being virtual replicas, BIM objects are intelligent components that come with geometry and the ability to store data. This intelligence allows the model to adapt seamlessly; if any element is changed, the BIM software automatically updates the entire model. This capability ensures that the model remains consistent and coordinated throughout the entire process.
Such functionality fosters a collaborative environment where structural engineers, architects, MEP engineers, designers, project managers, and contractors can work more effectively together. By maintaining up-to-date and synchronized data, everyone involved in the project can make informed decisions, reducing errors and improving efficiency right from the design stage through to construction.

What Additional Elements Are Included in Levels 4, 5, and 6 BIM?

Building Information Modeling (BIM) evolves significantly as it progresses through levels. Each level adds unique data layers, enhancing project execution and sustainability. Here’s how Levels 4, 5, and 6 enrich the BIM framework:
