New technologies have opened up many pathways for construction teams and designers alike. One of these technologies are 3D laser scanners.

Handheld laser scanners and tripod-based laser scanners are useful in construction due to their versatility and ease of use. What used to take several people now takes a few measurements with this easy-to-use tool.

If you want to learn how a 3D laser scanner can help in your next construction project, continue reading below. We'll show you what a laser scanner can do for you.


How Does a 3D Laser Scanner Work?

Before explaining what a laser scanner can do on any project, it's important to understand how it scans objects.

There are several types of laser scanners, with several different processes for scanning. But the principles are the same across all laser scanners.

The laser scanner emits a pulse of light at a given interval. Some photons of this light are reflected off surfaces and back towards the scanner. The time that it took to reflect is then measured.

This measurement allows for the scanner to calculate the distance between itself and a point on an object. It's akin to using an echo to determine how far away a wall is, only with a lot more precision.

The scanner then positions points in a digital space. This scan is called a "point cloud" and is made of thousands of individual points, each point representing a measurement.

With a little math, this point cloud is viewed as a "mesh" in a digital program. This mesh represents the surface of any object captured using the laser scanner. With this mesh, an entirely digital copy of any construction or object can be visualized using 3D programs.

Digital scans of objects are accurate to incredible precision. They include many details that would be missed with photography or videography alone.


Digitalized Projects

A 3D laser scanner's ability to turn real objects into digital objects is what makes them so useful in construction applications. The same ability also allows them to have increasingly useful engineering applications in workshops.

Digitalized projects are important for developers, designers, clients and contractors alike. All parties involved can have a copy of the project, ready for viewing when required. 

What used to take a tour of a construction site or a team of drafters can now be viewed through a screen.



In a digital world, it's important to take advantage of collaboration in the construction industry.

Architects and contractors can benefit heavily from a digital copy, more so than developers. By having digital copies of their projects through 3D scans, they are able to manipulate the construction site without drastic consequences.

Clients can also benefit from these changes. Any request made by a client can be tested through these same methods, allowing for final decisions to be made quickyly.

Collaboration makes for an unprecedented level of closeness in the modern era. While old tools may provide this collaboration, none are able to do it to the level that 3D scans can bring.


Retrofitting and Changes

Years after finishing a construction project, 3D scans are still incredibly useful to have. They show the baseline of any project, allowing for future developers to see a before and after of the site.

Owners are then able to make any additions to projects in accordance with these original scans. The flexibility of 3D programs allows for documenting changes, giving building owners and developers this history for years to come.



Laser scans aren't limited to during or after construction. They can also be done prior to construction by creating digital copies of entire areas for surveys.

Having a digital copy of an area is important when accurate detail is important. Cliff faces, caverns, hillsides or existing structures are only a few examples of survey locations where this detail is needed.

Without a 3D scan, these areas would be hard to interpret in software programs, leading to budget issues and labor constraints. Too much time would be spent with accuracy or dealing with variables in construction. Having a 3D scan done makes quick work of any surveying job.


Design Reevaluation

Over the course of a project, constructions and designs will have unintentional or intentional changes done to them. Reevaluation of constructions and designs is necessary to ensure proper standards.

This additional step in construction often takes additional resources. It prolongs a project's finish date.

Laser scans simplify this reevaluation process. Construction teams are able to create models of their sites simply by using the scanning device. Any changes from original designs can be shown through digital mediums and corrected easily.


Increasing Efficiency

A laser scanner works for everyone on a construction site. With the right laser scanner, construction projects can see lower impacts on their budget and more efficiency throughout construction steps.

Laser scanners allow contractors and designers to interpret changes to their plans immediately. Digital construction plans can show how to utilize resources, equipment and other materials on an up-to-date basis.

Such efficiency is impossible with traditional tools. When laser scans are this easy, every other part of construction becomes a little easier.
