3d measurement scanning

3D laser scanningof retail properties

To determine the exact area of existing retail property or to draw in a new store exactly, a good underlay is important. The quality of the measurement also determines the quality of execution and can therefore contribute to reducing failure costs.

There are different ways to perform a 3d survey: ‘manually’ digitally with a Totalstation or the method that NewArmstrong currently uses most: a 3d laser scan . NewArmstrong uses Faro laser scanners and Leica laser scanners.

The laser scanner is a device that performs measurements with a laser beam at high speed in a 360 degree field. These measurements are brought together in a point cloud ( point cloud ). A point cloud can have an accuracy of 3 mm.

A point cloud is not yet a model. A point cloud can be used for modeling or can be used to draw a model.

Whether laser scanning is cheaper or more expensive than traditional methods depends on the situation. For areas larger than 500 m2 or for a building with several rooms, the tipping point where a 3d laser scan is cheaper is early on. In order to determine where that tipping point lies, we would be happy to make a no-obligation analysis of your situation. A 3d laser scan offers distinct advantages over traditional surveying.

The benefits of a 3d laser scan and a Point Cloud:

>It gives a perfect reality: not a model, but reality.

>It is faster than traditional surveying: a shorter time on location.

>The point cloud is immediately in 3d, albeit in measuring points. This prevents differences of interpretation that can lead to errors.

>It’s exactly: it captures everything. You cannot ‘skip’ parts with a good scan plan: it is also more precise in preventing differences in interpretation of notes or measurement data.

> It provides a 360 degree photo viewer, which allows you to look anywhere.

>An accurate point cloud helps with construction preparation. A good point cloud can be made in such a way that you don’t have to go back to location to measure something. It leads to less site visits.

>The laser scan or measurement with a pointcloud can be used for both 2d drawing work ( AutoCad) and 3d drawing work ( Revit or ArchiCAD).

>A point cloud can be constructed in such a way that part of the drawing work can be omitted. Drawing can also be done in phases. You can already start working out while part of the model is still being built.

>A point cloud makes creating a few extra cross-sections very easy: you cut the point cloud at a different position by generating an extra cross-section: no extra measurements needed.

>A model helps with quantification, cost estimates and budgeting.

>It prevents failure costs.

>Through better construction preparation, a construction can be well planned, resulting in a shorter construction time and lower failure costs.

NewArmstrong’s method for a 3d survey:

>By conducting archival research in advance of a survey, we know the structure of a building and we know what we want to have measured.

>We work on the basis of a scan plan. By planning this well, we ensure that we do not scan too much (which leads to too long processing time and heavy point clouds), nor too little (missing information).

>There is a difference between scanning in black and white and color. Scanning in black and white is faster and cheaper, but a scan in color sometimes provides important additional information. We make a conscious choice to scan in black and white or in colour.

>We use our engineers to measure, so that they know what they are looking at and what is important to document.

>For large surfaces, we work with 2 scanners on mobile tripods. This allows us to achieve a high speed of scans, which leads to high efficiency and therefore low costs.

>We can measure above ceilings (difficult to see areas).

>We can measure with a high tripod: measuring at height.

>In dark rooms (for example above ceilings) we scan in black and white.

>We also have the scan operator draw the point cloud, so that he/she knows what he/she is looking at.

Specific cases:

Situations that NewArmstrong specifically uses 3d laser scanning for:

>Projects where site visits are disruptive or limited (retail, hotels, retail properties, museums).

>Monumental buildings where subsidence or subsidence must be documented.

– Baseline measurements (for monumental buildings), where the existing situation must be documented in order to determine an exact repair in the event of building damage.

Do you have a situation where you wonder whether a 3d survey offers added value? Our 3d scan specialist Erik de Jong can quickly provide insight into whether there is a business case for this.
