3D Scanning In Brisbane

1. Factors to Consider when Availing 3D Building Scanning Services

2. Today, Brisbane surveyors use 3D building scanning services to provide precise data needed in building construction projects. On that, there are certain things to consider when availing 3D building scanning services. In this article, we discuss what those are.

3. How it works Before we proceed, let’s quickly discuss how surveyors perform 3D scanning in Brisbane, or anywhere else for that matter. Once surveyors have set up the equipment on-site, it beams a line of laser towards a target. Each time it hits a surface, it creates a data point. A laser scanner can capture & record between 50,000 to 1,000,000 points in one second. These points form what we call a point cloud. Once done, surveyors return to the office to perform 3D building modelling using compatible software. Other than 3D models, they can also create 2D drawings for detail surveys & as-built models, among others.

4. Factors to consider Now that we know how 3D building scanning services work, let’s discuss the things we need to consider when availing it. Various surveying firms offer 3D scanning in Brisbane. On that, knowing the factors that help surveyors determine which laser scanner to use makes all the difference in achieving the necessary data along with the best value for one’s money.

5. Level of Detail Needed To start, the most basic determining factor in finding the right 3D building scanning services is the level of detail needed. We can divide it into three levels: basic, moderate & advanced. ● Basic - This covers laser scanning for checking purposes. An example would be monitoring construction progress against the project design. ● Moderate - This covers a more thorough evaluation of a certain construction aspect like the flatness of a concrete floor. The output of a laser scan can be colour-coded to show differences in elevation. With this, the project team can determine the volume of material needed for adjustments.

6. Level of Detail Needed ● Advanced - This covers providing any lacking information for construction projects. Particularly for renovation projects, 3D building modelling can supply data on a property’s existing condition.

7. Site to be Surveyed Other than the level of detail needed, another important thing to consider when availing 3D scanning in Brisbane is the site to be surveyed. Factors like height & temperature play a huge part in the effectivity of a laser scanner. For instance, the scanner must be able to cover a longer range with the same accuracy if the building or structure is of considerable height. Other than that, we should also check for temperature & weather patterns to make sure that the laser scanner can perform as expected in case of extreme conditions.

8. Hardware & Software Used Once we know the level of detail we need & the site conditions, the next thing to consider is the hardware used. Different surveyors use different scanners. With a very wide range of laser scanners available in the market, there is bound to be a scanner for any requirement. On that, the equipment a surveyor uses must meet our specific requirements. For example, on one hand, a basic spot check will most likely not require a scanner that captures one million points per second. On the other hand, we need such scanning capability if we’re following a strict timetable & need high-resolution data of a vast area in a short time. Moreover, the scanner must be able to provide accurate data considering site conditions. When it comes to the software, the surveyors must use a compatible one that can provide the output we need. As discussed above, they can create different types of models or drawings from a scan.

9. Final Thoughts There are still other things we need to consider when availing 3D building scanning services but the three factors mentioned here are always the top ones. That said, we need to make sure we gather information from different surveying firms in our area. This provides us with options & allows us to see which ones can not only give us the data we need but also provide the best value for our money.
