Building information modeling (BIM) creates a digital representation that communicates the physical and functional characteristics of a project. BIM is growing in popularity because of the many benefits it provides, including better visualization, speed and collaboration.

To understand how BIM works, it is important to recognize the functions of the different dimensions, including 2D, 3D, 4D and 5D BIM:

2D BIM: 2D is the most basic level of BIM. It consists of 2D drawings created using computer-aided design (CAD) or drawings done by hand. The 2D data is used in the different BIM dimensions.

3D BIM: 3D BIM involves creating a digital 3D model of a building or infrastructure project, including information about the physical geometry and spatial relationships of the building’s components. One of the current uses of BIM is to aid in clash detection, so teams can make adjustments early in the design phase to avoid potential problems in the build phase of a project.

4D BIM: 4D BIM takes 3D BIM a step further by adding the element of time. It includes information about the construction schedule, which allows for better planning of construction activities. 4D BIM enables teams to create a visual timeline of the construction process, so they can see how the project will progress over time. It helps streamline activities and correct any potential scheduling issues before building begins.

5D BIM: 5D BIM adds the element of cost to 3D and 4D models, including information about the price of materials, labor and other resources. This helps teams create more accurate cost estimates and identify potential cost savings by optimizing resource management. A 5D BIM model can also track costs throughout the construction process.

BIM tools are even more effective when integrated with other critical technology, such as estimating, takeoff, financial and project management solutions. Utilizing BIM with estimating and takeoff software, for example, can help teams better understand construction project plans and accelerate the development of quantities and variances whenever changes occur. Combining these powerful tools streamlines workflows and automates the estimating takeoff process, enabling teams to create more accurate estimates in less time.

BIM technology, especially when integrated as part of a robust tech stack, improves collaboration, reduces risk and increases efficiency throughout the project lifecycle. Moving forward, BIM technology will become a necessity for businesses to remain competitive. And, as technology continues to evolve, emerging technologies such as artificial intelligence, augmented reality and virtual reality could open up even more possibilities for BIM.
