BIM Estimating has made the process of construction easier than ever. It helps investors and stakeholders to make more practical decisions when it comes to finances. In addition to that, it also makes sure that resource allocation is optimal and is aligned with the project’s feasibility.
It not only streamlines the process of construction but also improves accuracy and elevates decision-making at each step.
What is BIM Estimating?
In simple words, a building information model for a particular project is used to create precise estimates. This estimate can be either related to quantities or costs. When we talk about the level of advancement of BIM, it has transformed the field of construction in so many ways. It enables experts to visually evaluate what resources are required for a project. It does so by creating a 3D model.
What are BIM Estimating Services?
In the construction industry, BIM Estimating Services are widely used for various reasons such as;
1) Cumulation of Data
With BIM software, an expert can develop detailed 3D models that encompass and accumulate different aspects of a project which can be related to mechanical, electrical or plumbing systems. These models include all the essential information about the components involved and this serves as a base for accurate estimation.
2) Precise Quantification
This is considered one of the most advanced tools in construction which facilitates precise quantification of required resources such as materials. An expert can precisely quantify how much material is needed. This quantification acts as a foundation for accurate cost estimation. It may include:
- Bricks
- Cement
- Concrete
- Lumber
- Piping
- Fixtures
- Metal
- Paint
- Drywall
- Any other primary material
3) 3D Visualization
A BIM model can more clearly present even the minute details of a project as it enhances the visualization process. It allows an expert to better understand the project’s design, making sure that the BIM Estimating process is accurate to the dot. This visualization can identify what elements are major cost drivers whether it is architectural features or selection of resources.
4) Integration with Other Software
BIM can be integrated with various other tools as it will ensure that the 3D visuals of a building are more comprehensive as well as accurate. These tools are as follows:
- Unreal Engine
- Revit
- AutoCAD
- Lumion
BIM Cost Estimating Methods
Several BIM-based cost estimation methods are applied for efficient cost management in a construction project. These methods are mentioned below:
Quantity Takeoff
It involves deriving quantities of required materials directly from a BIM model
Assembly Based Method
As the name suggests, it includes making assemblies of building components within a BIM Model.
Parametric Method
In this method, a cost is associated with the objects in a BIM model. Historical data is utilized to define the cost parameters in this method
Cost Database Method
The software can integrate with an external cost database so that estimators can analyze them. This will help them determine the costs of various Building elements

Why BIM Estimating Outweighs Traditional Approach?
With all that has been discussed above, BIM Estimating certainly has numerous advantages over traditional approaches and some of these advantages are as follows:
– It improved precision in estimating what components are required
– It saves time to a great extent by making sure that the process is automated
– BIM model seamlessly integrates with a design and can be flexible and adaptable to many later changes
– With BIM Estimating, cost management becomes efficient ensuring there are no cost overruns throughout a project’s life cycle.
– In BIM Estimating, collaboration is assured among various experts i.e. architects, designers, contractors and estimators to make sure that all are on the same page.
– BIM depicts a clear presentation of a building making sure that transparency is assured for all the investors
Bottom line
In the end, BIM Estimating has made cost and resource management more easier and accurate. It has not only improved the process of calculations but also it has made the process of resource utilization more effective. Also, useful information can be shared quickly without any delays. With BIM software, an extensive 3D model is developed which in return leads to precise cost estimates. On the other hand, conventional ways of designing required repetitive tasks, more time and more resources which were prone to human errors as well. This article discusses how BIM has revolutionized the process of estimating in a construction project. Also, how effectively it can provide various services along with several cost estimation methods as well.
