A Brief Overview of Scan To BIM

Scan-to-BIM is the process of creating a digital representation of existing buildings. In Scan-to-BIM, 3D laser scanners are used for capturing a high-density point cloud of a site or physical structure. This leads to creating and maintaining a BIM model that reflects the as-is condition of the site.  

The models made by the Scan-to-BIM service provider can be used for as-built documentation, additions, facility management, and project renovations. Additionally, models offered by Scan-to-BIM service providers can also be used for comparing against the original plan, topographic registrations, etc. 

This is just a basic summary of Scan-to-BIM services offered by a Scan-to-BIM service provider. To have the complete picture of Scan-to-BIM it is important to step back a bit and consider Scan-to-BIM in the broader context of BIM. For doing that let’s understand the implication of BIM in the architecture, engineering, and construction industries. 

Building Information Modeling

BIM can be defined as a digital representation of the physical and functional characteristics of a building. A BIM offers shared knowledge or information about a facility which forms a reliable basis for the decision that is made during the life cycle. The information offered by BIM can thus be used for managing the building from the conception to the demolition phase. 

Relation of BIM to Scan-to-BIM

With the growing demand for BIM implementation in the AEC industry, the demand for creating BIM schematics for existing buildings is also growing. Scan-to-BIM has quickly become an integral part of the BIM process. When there is a pre-existing structure, Scan-to-BIM service providers can use laser scanning technologies to create an accurate BIM model of the same which can offer critical information for the designer to work upon. 

Problems that can be solved by the Scan-to-BIM process

Designers have to often rely on unreliable or incomplete information for creating the BIM models of existing buildings. The as-built documentation that the designers rely on is often found to be fragmented and outdated. As such the BIM modeler has to spend hours meticulously piecing together all the available information and creating a cohesive BIM model. However, the BIM model that is created after investing so much effort cannot be trusted. 

Errors introduced into the model during the design phase can have great consequences later. Besides, collecting data during the construction phase can be a challenging task. Often the engineers have to physically visit the site and take painstaking measurements and photos. But the data thus collected can still be erroneous due to human errors. 

This is where a point cloud services provider can help. The AEC professionals can easily afford a scan-to-BIM workflow. The Scan-to-BIM service provider deploys a 3D laser scanner on the site to capture and create a 3D model of the building in BIM. This model can help the designers and engineers to process further works with ease. 

In conclusion

Owing to the benefits offered by Scan-to-BIM, it has therefore become an integral process of all projects involving the refurbishment of existing structures. Want to know more? Connect with a leading Scan-to-BIM service provider to know more.
