C39 Objective – Griro

Location: Bucharest

Deliverables: 1 floor plan, 4 facades, 2 cross sections

Scanned surface: 4111 sqm

Equipment used: Trimble TX8 / Robotic Trimble S5 total station

Team: 2 land surveyors with experience in 3D scanning / 1 land surveyor with experience in point cloud processing

Workflow (office and on-site):

  • Acquisition of site located in Bucharest
  • Establishing the positioning for the scanning stations and the resolution used according to the degree of detail required by the design theme
  • Connecting the previously positioned stations was carried out on the basis of the scanned common plans (the common plans are represented by floor, ceiling, partition walls). A total of 87 3D laser scanning stations were implemented
  • Point cloud registration was performed with Trimble RealWorks software with an overall cloud-to-cloud error of 2.2 mm
  • Recording the point cloud and placing it into the Stereographic 70
  • Extract horizontal sections and facades from the point cloud using AutoCAD software.
