BIM Dimensions

Building Information Modeling (BIM) embodies a dynamic approach to constructing information-rich models that span the entirety of a construction project's lifecycle.

As a project progresses through its various stages, the level of development within a BIM model advances incrementally, categorized into distinct levels such as LOD 100, 200, 300, and beyond.

BIM models serve specific, predefined purposes known as use cases, tailored to meet the requirements of each project stage and its unique complexity. These predefined use cases introduce additional parameters, shaping the evolving information within the BIM model, a concept often referred to as BIM dimensions.

The integration of these dimensions enriches the data associated with the model, fostering a deeper understanding of the construction project. In the contemporary landscape, BIM technology has transcended traditional 3D and 4D dimensions, evolving into more sophisticated realms such as 5D, 6D, and 7D, poised to revolutionize the AEC industry.

Each BIM dimension - from 3D to 7D - serves a distinct purpose, offering insights into the project's cost estimation, timeline, and future sustainability. This multi-dimensional approach empowers stakeholders to make informed decisions, driving efficiency and innovation across the construction lifecycle.

What is 3D BIM? – BIM 3rd Dimension: All About Geometry


3D, as we are all commonly aware, represents the three geographical dimensions (x, y, z) of a building structure. The geographical capabilities help stakeholders to visualize a building’s structure in 3 dimensions even before the project is started.

3D BIM enables all the stakeholders to collaborate effectively for modeling and solving typical structural problems. Also, as everything is stored at a central location i.e. the BIM model, it becomes easier to resolve issues at a future stage.

What is 4D BIM? – BIM 4th Dimensions: Duration, Timeline & Scheduling


4D is related to planning the construction site by adding a new element i.e. time. Scheduling data helps in outlining how much time will be involved in the completion of the project and how will the project evolve over time.The information can provide elaboration about the time taken for installation or construction, the time needed to make the project operational, the sequence of installation of various components, along with other scheduling information.

What is 5D BIM? – BIM 5th Dimension: Cost Estimation, Analysis, and Budgetary Tracking


5D BIM is useful in cases where budget analysis and cost estimation are required from the beginning of any project. It goes without saying that cost is one of the most important elements associated with a project. 5D BIM enables project promoters and owners to analyze the costs that will be incurred over time in the project activities.

What is 6D BIM? – BIM 6th Dimension: Making a Structure Self-Sustainable & Energy Efficient


6D building information modeling helps to analyze the energy consumption of a building and come out with energy estimates at the initial design stages.

Accounting for various life stages of a structure, 6D BIM ensures accurate prediction of energy consumption requirements. 6D BIM technology takes the industry a step beyond the conventional approach that just focuses on the upfront costs associated with a project.

This approach helps in getting an idea of the entire cost of an asset and how the money should be spent on achieving sustainability and cost-efficiency.

This essentially involves information about a component’s manufacturer, installation date, maintenance schedule, configuration details for best performance, energy requirement, and decommissioning information.

What is 7D BIM? – BIM 7th Dimension: Holistic Facility Management Information for Entire Lifecycle


7D BIM is all about operations and facility management by building managers and owners. The dimension is used to track important asset data such as its status, maintenance/operation manuals, warranty information, technical specifications, etc. to be used at a future stage. 7D BIM is a unique approach where everything related to the facility management process is collated in a single place within the building information model.

Such a tactic helps in improving the quality of service delivery during the entire lifecycle of a project. Using BIM for facility management ensures that everything in a project stays in its best shape from day 1 to the day of demolition of a structure. At United-BIM Inc., we aim to deliver peace of mind and value BIM Modeling Services through quality, speed, and a consultative approach.

What is 8D BIM? – BIM 8th Dimension: Safety


Building upon traditional BIM dimensions, 8D BIM places a paramount emphasis on safety throughout the construction process. This dimension integrates advanced safety analysis tools and simulations, allowing stakeholders to identify and mitigate potential safety hazards with precision. From analyzing fall protection systems to simulating emergency evacuation procedures, 8D BIM enables proactive safety measures to be implemented at every stage of the project.

Additionally, innovative features such as virtual reality (VR) safety training and augmented reality (AR) hazard detection further enhance safety protocols, ensuring the well-being of workers and minimizing the risk of accidents on-site. Through the comprehensive integration of safety considerations, 8D BIM sets a new standard for construction project management that prioritizes the health and safety of all involved parties.

What is 9D BIM? – BIM 9th Dimension: Lean Construction


Transitioning into the realm of 9D BIM introduces a focus on lean construction principles, revolutionizing project delivery methods and enhancing efficiency throughout the construction lifecycle. In this dimension, BIM technology is leveraged to streamline workflows, minimize waste, and maximize value for all stakeholders involved. Through the integration of lean construction methodologies, such as pull planning and continuous improvement cycles, 9D BIM facilitates collaborative decision-making and fosters a culture of innovation on construction sites. By optimizing resource allocation, reducing project timelines, and enhancing communication among project teams, 9D BIM empowers stakeholders to deliver projects more effectively while maintaining a relentless focus on delivering value to clients.

What is 10D BIM? – BIM 10th Dimension: Industrialized Construction


10D BIM transforms industrialized construction methods, ushering in a new era of efficiency and precision. In this dimension, BIM technology seamlessly integrates with industrialized construction techniques, such as prefabrication and modularization, to streamline project delivery and optimize resource utilization. Through advanced automation and digital fabrication capabilities, 10D BIM enables the mass production of building components with unparalleled accuracy and consistency.

Furthermore, real-time data analytics and predictive modeling empower stakeholders to optimize supply chain logistics, minimize material waste, and reduce construction timelines. By harnessing the full potential of industrialized construction methods and BIM technology, 10D BIM sets a new standard for construction productivity and sustainability, driving the industry towards a more efficient and resilient future.
