What is BIM?

Building Information Modeling is a digitized technique of creating and managing information on a construction project. The coordinated design-build process involves a combination of 3D models and connected data like product, execution and facility management handover information. The process and data of Building Information Modeling are internationally defined in the ISO 19650 as well as 12006 standards. Whenever specific information is provided in the model, a different dimension is set, leading to around 8 key dimensions like time, cost, sustainability and so on. In the architectural, engineering and construction (AEC) sector, BIM is increasingly used to reduce material wastage and assess virtual risks. BIM also helps to detect clashes and decrease errors on-site. To put it clearly, the technique supports the construction and the design process from conception to completion and beyond for all stakeholders involved in the project. Hence, there is no doubt about the fact that Building Information Modeling is revolutionizing the construction sector by providing information access and collaborating with project team members. So, every builder and designer must understand the BIM model and its various components.

What are BIM Dimensions?

Building Information Modeling doesn’t just mean the 3D model creation of a structure. This implies information associated with the phases of design, construction and maintenance. BIM dimensions 2D, 3D, 4D, 5D, 6D, 7D and even 8D enhance the model data for a better understanding of the building project. Additional information visualizes the process of project delivery, cost and building facility maintenance.

BIM Dimensions/Level of Information in BIM Data:

Types of Dimensions & Purpose:

3D Modeling– Geometrical/Graphical Information – Visualize Building in 3 Dimensions by Updating Views throughout project life-cycle from conception to completion

4D Scheduling/Simulation/Sequencing/Construction Phasing – Time-Related Information to model construction sequence & plan project

5D Cost Estimation/Analysis/Cost Management/Quantity Take-off/Bill of Materials – Tracking Budget & Making Cost Analysis

6D Sustainability/Energy Analysis – Accurate energy estimation in the design-build stage for high-performance facilities

7D Facility Management & Maintenance – Facility Operations & Maintenance throughout the building lifecycle

8D Site Accident Prevention – Design Optimization, providing the best result at the pre-construction stage

Significance of BIM Dimensions:

• Help to start client conversations, demonstrate several BIM use cases and develop accurate project requirements

• Provide an improved understanding of building projects & the process of linking additional data dimensions to building models

• Facilitate engineers to get a better building insight and virtually assess project risks through intelligent model-based technique

• Reduce wastage for building contractors

• Decrease inaccuracy in information exchange for architects

• Collect information like reality capture data and store it in a user-friendly location

• Give real-time and centralized information to project stakeholders

• Enable collaboration amongst suppliers, building owners & other AEC professionals

Explore the different BIM dimensions in detail from 3D to 8D.

3D BIM: Shared & Coordinated Information Model

3D digital geometric model is the most popular BIM dimension having X-axis, Y-axis and Z-axis of a building. BIM 3D Modeling helps to generate schedules and report on different types of objects within the 3D model. Usually, multiple 3D models are combined to find out geometric clashes to enhance project efficiency and reduce the risk of project errors. Specification information gets linked to the objects for providing a richer set of coordinated information. If information gets stored in a cloud tool, detailed decisions could be made in a database, coordinating complex information in the 3D model.

Purpose: Model sharing in a common data environment (CDE) for effective design, construction and maintenance of the building project


• Creation of schematic design, design development support, construction documentation, and record drawings

• Geographical data extracted from the model facilitate stakeholders to visualize building at the pre-construction stage

• Stakeholders examine and address structural issues before proceeding to the next level

Benefits of 3D BIM dimension:

• Improved 3D Visualization

• Clash Detection at pre-construction

• Enhanced communication amongst team members

• Ensure project transparency

• Detailed model creation to share realistic design expectations amongst stakeholders

• Reduced rework and design revisions through effective communication

• Multidisciplinary collaboration, reducing rework

4D BIM: Scheduling Information to Construction Sequence

Adding a time dimension to the 3D model enables project team members to visualize how the construction is sequenced. However, considering the point of the contractors, this is very significant. 4D BIM is a great step ahead that demonstrates collaboration between the design and construction team through model sharing. 4D BIM model reveals additional dimensions, like time element and scheduling data. The technique provides additional information about a building project in the form of scheduling data. As the project progresses, this data gets added to the components being built.

Purpose: 4D provides an extra dimension to a project, describing task duration & time for building development with regards to the construction phases.
