Optimizing or modifying the built environment can be hard without understanding the space you’re working in
What are laser surveys?
Laser surveys are a process by which spatial detail is captured using high-tech three-dimensional (3D) laser scanners.
A laser scanner is methodically placed within the space to be surveyed. It scans all objects in the room, building or area and gathers the full perspective of the space.
High definition (HD) laser scanners record angles and distances through analysis of returned laser light signals as they bounce back from surfaces. Each signal creates a ‘point’ in 3D space, which combine to form a ‘point cloud’.
As the space is scanned, the survey captures data in the form of a point cloud which is then registered to create a 3D model.
What are laser surveys used for?
Laser surveys are most often used by construction and spatial design teams.
The data generated by laser scanning can be used by construction professionals to understand the space and identify the freedom or constraints which will impact their project.
Often, laser surveys are used as part of a wider planning process. The data from laser surveys is registered as a point cloud, from which a 3D Revit model can be generated. These are dimensionally accurate, helping visualise the space and facilitate the design process.
The base model is edited within the Revit software, where existing elements can be retained or removed, alongside the new design proposals.
What are the advantages of laser surveys?
Laser surveys capture highly accurate data at rapid speeds.
The laser scanner records millions of data points in mere seconds, ensuring large environments can be surveyed quickly. This is ideal for time-sensitive projects.
The speed of laser scanning is one important reason why it is becoming so widely utilised in a diverse range of industries.
Laser surveying can be used to scan hard-to-reach areas. This is ideal for more complex spaces, in which certain objects may be obscured or otherwise difficult to reach, such as ceiling voids.
Non invasive data capture
Another advantage of laser surveys is that they do not require contact with the existing structure to capture data. This is great for situations in which there are potentially fragile or sensitive objects or environments. For example, in cultural or heritage settings in which preservation is key.
By using laser scanning, laser surveys are a non-invasive method of gathering high-detail data.
