WHY RED LASER SCANNING IS DIFFERENT TO MOST OTHER BUILDING SURVEYORS
Measured Building Surveys are highly accurate built surveys carried out before, during and/or after construction projects.
This type of survey is used for verification, records, area calculation and new design proposal purposes.
Some clients and designers take the risk of working from blueprints in attempt to make savings on as-built measured surveys. Blueprints are plans and elevations of a proposed design that come with the property when a client purchases it.
However, the reality is that what was intended to be built in the design phase and what actually gets built never quite match up due to changes in circumstances, availability of materials and other variables.
Working directly from blueprints is, therefore, high risk. Basing the design on inaccurate information usually leads to variations and project delays that can be very costly.
Approaches to building measured survey
The idea behind a building measured survey service is to provide designers and architects with accurate information that allows them to start working on design proposals, eliminating the chances of variations caused from basing plans on inaccurate data.
There are, however, different approaches towards doing a building measured survey. The most common way of undertaking a building measured survey is done manually, using a Disto laser measure. This process involves a team of surveyors inspecting the building and manually taking all of the measurements of the building that are necessary to produce accurate plans and elevations. Once the measurements have been recorded, plans and elevations of the building are produced from recorded information.
This method of building measured survey makes surveyors life significantly easier compared to the previously used tape measure surveys, allowing them to spend less time on site recording data. A laser Disto measurer allows surveyors to take instant measurements in any direction. However, just like the tape measure, it is limited to only one measurement at a time.
3D laser scanning technology for measured surveys
In the past few years, 3D laser scanning measured surveys have become more and more popular.
A complicated building with complex shapes of walls and ceiling angles can now be surveyed by just one person using 3D laser scanning equipment.
Benefits of 3D laser scanning
Terrestrial 3D laser scanning equipment used at Red Laser Scanning London allows us to capture all visible data in 360 degrees up to 130 meters in x, y and z coordinates with an accuracy error of just 2mm.
For example, a façade of a building 7 storeys high with a lot of architectural detail could take a team of surveyors days to measure all of the details using Disto laser measures, plus an erection of scaffolding or other special equipment to allow safe access to undertake measurements at heights. The same result can now be achieved within minutes by just one surveyor using a 3D laser scanner, without the requirement of scaffolding or any other tools.
When a 3D laser measure survey is undertaken, 360 TrueView imagery and a point cloud is generated, allowing surveyors to undertake virtual tours around the site and extract any measurements easily.
This cutting-edge technology has already proven itself to make architectural and design processes much easier, and saves clients valuable time and money whilst providing highly accurate results.
