Location: Fundulea, Călărași
Objective: Floor plans and facades for determining verticality, georeferencing, construction behavior tracking in time
Deliverables: 3 floor plans, 4 facades
Scanning area: 570 sqm
Equipment used: Trimble TX8, Nivelă Trimble DiNi 03, Mira Invar
Team: 3 land surveyors with experience in 3D scanning and engineering topography/ 1 land surveyor with experience in point cloud processing
Workflow (office and on-site):
- Installation of compaction marks (11) according to the design theme
- Installation of at least 3 reference parts located outside the area of influence of new constructions
- Determining the positioning of the scanning stations as well as the resolution used according to the necessary degree of detail imposed by the design theme
- The connection of the positioned stations was made on the basis of spherical targets – to ensure a millimeter precision. A total of 25 3D laser scanning stations were completed
- The point cloud recording was done with the Trimble RealWorks program with an overall deviation of 1.2 mm (overall cloud-to-cloud error)
- Recording the point cloud and placing it into the Stereographic 70
- Extract horizontal sections and facades from the point cloud using AutoCAD software.
