Building Surveying with Laser Scanning: An Overview

Building surveying with laser scanning is a specialized field that uses advanced technology to assess and inspect buildings. Laser scanning involves using a laser scanner to capture 3D images of buildings, which can then be analyzed to identify defects, measure dimensions, and assess the overall condition of the building. This technology is particularly useful in complex buildings or heritage buildings where traditional surveying methods may be challenging.

Laser scanning technology has revolutionized the way building surveying is conducted, as it allows for a faster and more accurate assessment of buildings. The technology is particularly useful in identifying defects in hard-to-reach areas, such as roofs, facades, and high-level structures. Laser scanners can be combined with drone technology or even simple rising tripods in order to gain a better vantage. With the development of SLAM technology such as GeoSLAM and the Leica BLK2GO, the engineer can capture large spaces in a much quicker time. 

Building Surveying Services with Laser Scanning

Building surveyors who use laser scanning technology can provide a range of specialized services, including:

• 3D modeling - laser scanning can be used to create accurate 3D models of buildings, which can then be used in design and planning.
• Building condition assessments - laser scanning can be used to assess the overall condition of a building, identify defects, and prioritize repairs.
• As-built documentation - laser scanning can be used to document the as-built condition of a building, which is particularly useful in refurbishment or renovation projects.
• Structural analysis - laser scanning can be used to identify and analyse structural issues in a building. This can be combined with technology such as remote sensors or non-destructive testing like Ground Penetrating Radar in order to gain a better understanding of what is going on beneath the surface.
• Historic building preservation - laser scanning can be used to document and preserve heritage buildings, which is particularly important for restoration projects. The most famous example of this is the rebuilding of Notre Dame Cathedral in Paris which is being done thanks to pointcloud data. 

Qualifications and Skills

To become a building surveyor with laser scanning expertise, you need to have a degree or professional qualification in building surveying, construction, or a related field, as well as specialized training in laser scanning technology. Other essential skills for building surveyors with laser scanning expertise include:

• Understanding of laser scanning technology - building surveyors need to have a strong understanding of how laser scanning technology works, as well as how to operate and interpret the data generated by the technology.
• Analytical skills - building surveyors need to be able to analyse complex data and make informed decisions.
• Attention to detail - building surveyors need to have a keen eye for detail to identify defects and assess the condition of a building accurately.
• Communication - building surveyors need to communicate their findings and recommendations to a range of stakeholders, including clients, contractors, and local authorities.
• Project management - building surveyors need to be able to oversee projects involving laser scanning technology, including planning, scheduling, and budgeting.
