What is Building Information Modelling (BIM)?

BIM, an innovative technology and methodology, has revolutionized the entire lifecycle of building projects, from design and analysis to construction and facility management. It represents both physical and functional aspects of a building through the usage of digital models that integrate a variety of data about a building’s elements and systems.

At its core, BIM allows architects, engineers, contractors, and clients to collaboratively visualize and plan a building in a virtual space, before its actual construction begins.This model functions as a collaborative knowledge hub, offering a dependable foundation of information regarding the facility. It serves as a valuable resource for making informed decisions throughout its entire lifespan.BIM goes beyond traditional 2D blueprints, offering three-dimensional, real-time, dynamic building modeling that can include information about time (4D), cost (5D), environmental impact (6D), and more.

A key advantage of BIM is the facilitation of coordination and collaboration among different stakeholders. BIM can help detect conflicts and potential problems early in the design phase, which can significantly reduce costly on-site adjustments and reworks. With BIM, changes made to the model are automatically updated across all views, enhancing the accuracy and consistency of project documentation.

Furthermore, BIM enables building performance analysis, sustainability evaluations, and lifecycle management, supporting better decision-making, productivity, and efficiency. For instance, a building’s energy performance can be analyzed and optimized using the model, which can lead to energy and cost savings over the building’s lifecycle.

BIM has become a critical component in the architecture, engineering, and construction (AEC) industries, with its adoption mandated in many countries. It is a game-changer, fostering a new era of integrated project delivery, where knowledge, resources, and outcomes are shared in a more transparent, efficient, and sustainable manner. Despite the initial learning curve and resource investment, BIM’s long-term benefits far outweigh these early challenges, making it an integral part of modern building design and construction.

The Evolution of Architectural Design: From Blueprints to CAD to BIM

The evolution of architectural design and planning has moved from blueprints to Computer-Aided Design (CAD) to Building Information Modeling (BIM), each leap providing more complex and comprehensive capabilities.

Blueprints, the traditional medium, were two-dimensional hand-drawn designs. They offered a static picture of the building plan, but lacked details about the structure’s function, materials, and systems. Furthermore, each blueprint represented a different aspect of the building, like the electrical or plumbing plan, and this lack of integration often led to errors or discrepancies.

The advent of CAD in the late 20th century automated and digitized the drawing process, which greatly enhanced precision, speed, and efficiency. CAD allowed architects and engineers to create digital 2D and 3D representations of buildings. However, these were still primarily graphical and any changes had to be manually updated across all relevant views, increasing the risk of human error.

BIM, the latest innovation, goes beyond creating visual models to integrating data about every component of a building. It allows designers to construct virtual 3D models that also encapsulate functional information, such as materials, cost, and timelines. Changes made in one view are automatically propagated throughout the model, reducing inconsistencies. BIM models also facilitate simulations, conflict detection, and performance analysis, enabling more informed decision-making.

Importantly, BIM fosters better collaboration among various stakeholders, such as architects, engineers, contractors, and clients, as everyone has access to the same, up-to-date model. This shared resource fosters transparency and efficiency throughout the building’s life cycle, from design to demolition.

In essence, the evolution from blueprints to CAD to BIM represents a shift from static, separate representations of buildings to dynamic, integrated models that offer comprehensive views of buildings, promoting productivity, accuracy, and sustainability in the architecture, engineering, and construction (AEC) industries.

Understanding BIM Objects

Building Information Modeling (BIM) objects are digital representations of physical and functional characteristics of a place or a thing. They serve as the fundamental components for constructing a BIM model.BIM objects can represent all the components that together form a building, ranging from structural elements like beams and columns to furniture and fixtures.

A BIM object carries a wealth of information about the component it represents. This includes geometric data, visual characteristics, and other related details such as manufacturer’s specifications, material type, cost, and environmental impact. This allows stakeholders to not only view the physical characteristics of the building but also understand its performance, cost, and sustainability metrics.

Importantly, BIM objects are intelligent; that is, they interact with each other within the model. For instance, if a wall object and a window object intersect, the wall will automatically create an opening for the window. This level of interaction can significantly enhance coordination and clash detection in the design process.

BIM objects can be either proprietary (specific to a manufacturer’s product) or generic (representing a typical product without specific branding). They can be downloaded from various online libraries and directly integrated into BIM software, streamlining the design process.

The “I” in BIM

The “I” in Building Information Modeling (BIM) stands for “Information”, which underscores the essence and power of BIM. Beyond creating 3D visualizations of a building, BIM encapsulates a vast range of data and information about a building’s physical and functional characteristics.

The “I” represents all the non-graphical information that can be associated with a BIM object or model. This can encompass everything from a component’s material properties, manufacturer’s details, and costs, to its maintenance schedules and environmental impact. The embedded data allows stakeholders to understand not just what the building will look like, but how it will function and perform over its entire lifecycle.

The information in BIM is consistent, coordinated, and comprehensive, providing a single, shared knowledge resource. Any change to the model is automatically updated across all views and schedules, maintaining accuracy and consistency in the information. This promotes improved collaboration, error detection, and decision-making among all project stakeholders.

Moreover, the “I” in BIM is intelligent and interoperable, enabling different systems and datasets to work together seamlessly. For instance, an architect can input design specifications into a BIM system, which a quantity surveyor can then use to generate precise cost estimates.

In essence, the “I” in BIM transforms the model from a simple digital representation to a rich, multi-dimensional resource that supports the design, construction, and management of a building. This ability to manage information effectively is what sets BIM apart from previous technologies and processes in the architecture, engineering, and construction (AEC) industries.

How is BIM Information Shared?

Building Information Modeling (BIM) information is shared through an approach known as Common Data Environment (CDE). A CDE is a single source of information for any given project, used to collect, manage, and disseminate all relevant documentation, graphics, and non-graphical data for multi-disciplinary teams in a managed process.

The CDE allows project stakeholders such as architects, engineers, contractors, and owners to access, contribute to, and collaborate on BIM data. This promotes transparency, minimizes the risk of miscommunication or data loss, and ensures everyone is working from the same, most recent information. Changes in one part of the model are automatically reflected across all views, keeping the information consistent and coordinated.

Sharing of BIM data is typically facilitated through cloud-based platforms, which enable real-time access to the model from various devices and locations. These platforms often come with features for version control, user access control, and tracking of changes, enhancing the security and traceability of data.

BIM data can also be shared across different software platforms using interoperable file formats like Industry Foundation Classes (IFC) and Construction Operations Building Information Exchange (COBie).IFC establishes a universally accepted standard for sharing BIM data openly, whereas COBie functions as a data format that captures and preserves essential project information from its inception, encompassing equipment lists, product data sheets, warranties, spare parts lists, and schedules for preventive maintenance.

What are BIM Levels?

BIM levels are stages that represent the industry’s maturity with respect to the application of BIM technology and processes. They were initially outlined by the UK government to set out a methodical approach to adopting BIM in the UK construction industry, but have since been recognized worldwide.

  1. BIM Level 0: At this stage, no BIM technology is employed. Design is typically represented through 2D CAD (Computer-Aided Design) drawings. Information exchange occurs through paper or electronic prints.
  2. BIM Level 1: This level introduces some degree of 3D CAD for concept work, but 2D processes are still used for statutory approval documentation and production information. Data may be shared electronically but it isn’t collaborative as each stakeholder publishes and manages their own data.
  3. BIM Level 2: At this level, collaborative 3D BIM is introduced. Every piece of project and asset information, documentation, and data exists in electronic form.There is a managed, shared common data environment and all parties are required to adopt the agreed processes and procedures, allowing for collaboration between different project teams. Importantly, BIM Level 2 uses distinct, federated BIM models – each discipline creates its own model, and they are brought together for clash detection and other purposes.
  4. BIM Level 3: Also known as “Open BIM,” this level introduces full collaboration between all disciplines by using a single, shared project model in a common data environment. This model is accessible to all and can be updated in real-time. It also aims to incorporate life-cycle management, allowing for optimal operation and maintenance of the asset after it has been built.

Enhancing BIM with Time, Cost, and Sustainability Dimensions: Exploring Levels 4, 5, and 6

The introduction of Level 4 BIM incorporates a critical element to the information model – the aspect of time. Often referred to as 4D BIM, this level integrates scheduling data that provides a timeline for each project phase and sequence of operations. By providing a clearer view of how construction phases unfold over time, 4D BIM supports more efficient planning, coordination, and execution of the construction project.

An illustration of Level 4 BIM is viewing a structure sequencing breakdown in a common data environment, based on concrete pouring numbers. This visual display allows stakeholders to anticipate potential scheduling conflicts and streamline their planning accordingly.

Level 5 BIM advances the information model by introducing cost-related data. This level enables the inclusion of cost estimations, budget analysis, and financial tracking within the BIM framework, often referred to as 5D BIM. This financial transparency empowers project owners to anticipate costs throughout the project lifecycle and adjust their budgetary plans in real-time, leading to more effective cost control and resource allocation.

The incorporation of Level 6 BIM brings sustainability and energy efficiency to the forefront. This level prioritizes the prediction of a building’s energy usage before construction even begins. Consequently, designers can account for more than the initial costs of a project, fostering an energy-efficient and environmentally conscious approach to construction. By anticipating and minimizing energy consumption, Level 6 BIM enables the creation of sustainable and energy-efficient structures.

The benefits of integrating Levels 4, 5, and 6 into BIM practices are manifold:

  • Improved project scheduling and site planning
  • Streamlined transitions between construction phases
  • The capability for real-time cost visualization and analysis
  • Long-term reduction in energy consumption
  • Enhanced post-handover management of the building or structure

By adding these dimensions to BIM, stakeholders can achieve a more comprehensive understanding of their projects, leading to improved efficiency, cost-effectiveness, and sustainability.

The progression through BIM levels represents increasing complexity, collaboration, and digital integration, enabling more efficient and effective planning, design, construction, and management of built assets.

As BIM continues to evolve, it’s worth noting that the terminology may change, as in the UK where the concept of “BIM Levels” has been transitioned to “BIM Stages” under the new ISO 19650 standard, which aims to create an international standard for managing information.
