The use of 3D Laser Scanning for Building Modeling

The utility of 3D scanning has been applied to many industries nowadays. With the wide range of potential features it brings, it is no wonder 3D scanning has become so popular. 3D scanning, especially that of the laser kind, has found its way into the action of building modeling too. Let’s take a look at how 3D laser scanning affects building modeling and how it’s used within this category.

The ability to 3D model projects and showcase them before they have been completed is a primary advantage of 3D modeling. However, even scanning itself has fruitful applications in this department.

The ability to scan existing objects allows us to represent the real-world picture of an already existing site. This picture can then be applied for plentiful useful situations. The actual scanning can take place on a newly started construction site, aiming to give the idea of the basics of the project. These types of scans are fruitful both for showcasing the current progress of work and getting a basis to work from. The initial scan can be modified to showcase the eventual goal of the project better.

Of course, we could also scan a heavily in-progress site. These sites are assumedly some way through the actual construction process, getting through a lot of the rough works already. It is at this point that a lot of extra problems can occur. Thus, the 3D laser scanning provides us with a fruitful solution that can be applied no matter the building. We can also adjust the potential changes requested by clients if you have the scans ready.

No matter the site’s completion, the 3D scans can easily be used for a wide array of useful things, from analyzing the current situation of the construction to better changing the previous plan. Of course, getting a proper scan of the area will be required. This is something you can learn more about too.

Making entire building models

The 3D modeling activities are frequently used to improve the overall idea of our projects. However, making these models can take quite a considerable amount of time, and sometimes we cannot afford that time. To get the entire process done faster without losing on the accuracy, we can use 3D scanning.

Standard 3D modeling requires us to build the entire showcase from the ground up. Starting with the simple details and adding more as the whole model progresses. Eventually, the model should be detailed enough to correspond to the real world building properly, or rather what it would become.

As mentioned, this process can take quite a lot of time. To cut down on the required time for each model, we can utilize 3D scanning. With 3D scans, we can get a scan of a building that corresponds to the one we have planned and wish to showcase. After scanning, the model will be rendered in full, with a decent amount of detail we’d otherwise have to add manually. From this point on, modelers can shape and change the model to the point where it fully represents the desired form of our project.

Project and design validation

The validation of various projects is done by carefully reviewing their features and traits. This is done in order to avoid bad building practices and avoid any possible dangers from the equation. The validation of either project or design requires the use of tools that can bring over the idea to engineers and clients alike.

The idea isn’t to just approve or deny a design. There are various types of labeling and color-coding for certain problems or necessary changes to the design that engineers frequently utilize. After all, doing a building project is a team effort, so it makes sense to get extra opinions and help from others.

With the 3D scanning, we can much better showcase the project during the validation and design approval stages. The extra benefits come in the form of being able to directly compare some other projects or finished buildings by 3D scanning them into models.

Having this immediate benefit is great for designers and engineers alike, streamlining the process and providing better quick insight into the matter. For example, it could take far more time trying to revise a 2D project and provide corresponding critiques than it does with a 3D one.

Enhances collaboration on and off the site

With the provided tools that 3D scanning brings, we can enhance the interaction between workers that are on-site as well as those who are working outside of it. The scans can give us a good idea of the overall work that needs to be finished around the current project, and with some management, we can assign different tasks based on difficulty.

Those on-site can be better coordinated and spend less time trying to figure out the approach to certain tasks. When those employed away from the site are concerned, this will help them get an immediate source of knowledge on the current state of the site. This, in turn, allows them to make snap adjustments and provide necessary assistance to people on site.

The extra cooperative abilities offered by 3D scanning shouldn’t be underestimated. Employing them can firmly enhance the construction project.


The benefits of 3D scanning cannot be denied, as we’ve seen, it can be applied in a lot of areas that have ties to building construction. For example, projecting the actual building, using the model for revision and design feedback, or even giving insight into the current state of construction are all options we can use it for.

Rather than spending a ton of time manually crafting 3D models, we can use 3D scanning to get a faster experience with our modeling endeavors. Even outside of the direct utility of 3D laser scanning, we can apply the information and results to better understand our workers working on the construction site. The information can also be applied to those who aren’t on it but rather work on maintaining the site at top capacity. It’s obvious that the utility of 3D laser scanning is firmly present in the overall building construction. Applying it can save us time, money, and a lot of stress.
