The surveyor has to gather as much information as needed before doing the actual job. Tools such as Google maps and other Global Positioning Systems (GPS) are to be utilised to learn more about the layout of the structure, its surroundings, the orientation, and obstacles.
Being prepared before the actual survey makes the job more comfortable which at the same time, ensures high accuracy.
The surveyor will then survey the building with all required techniques (Terrestrial Laser Scanning, Total Station, GPS RTK, 3D Aerial Mapping, and Photogrammetry) to deliver complex 3D data which is a base to produce highly accurate scaled drawings or 3D models.
When the area to be surveyed is huge, the surveyor conducts the survey in sections. One page is dedicated per section to accommodate enough data. The process goes on until the whole area is completely surveyed.
Typically, the surveyor will start the survey from one corner of the building and continues the survey in a clockwise or counter clockwise direction. Diagonal measurements are also taken to ensure accuracy.
Following the completion of the survey, Brighton Measured Survey will draw up the measured floor plans, sections, elevations, or as built plans using the latest technology.
Survey data can also be instantly accessed through an online portal – Webshare Cloud Service, where the client can view a panorama of each captured on-site scan and perform distance measurements of selected points or check their coordinates.
The surveyor must be an expert in the field since accuracy is critically important. Measurement errors can cause serious implications in your project such as delays, additional expenses, disputes, and other issues that will affect your reputation as well as your clients.
Accuracy means experience and we at the Brighton Measured Survey’s team is comprised of experienced professionals in 3D laser scanning specialising in measured building survey, registration of 3D point cloud data, producing as built 2D drawings, and building 3D BIM models.
