Evaluation of Inventory Surveying of Façade Scaffolding Conducted During ORKWIZ Project

The publication focuses on the issue of inventory surveying of façade scaffolding. The authors considered various land surveying methods such as photogrammetry, laser scanning or total station. To test these methods, sample measurements were performed on the deployed scaffolding. Specific equipment was used: GOM Tritop system with invar scale patterns, Leica C20 scanner and Leica TS50 total station. The authors present arguments for and against mentioned methods and also an analysis of the measurements of 10 scaffoldings. Finally, as a leading method the total station was chosen. The results of the tests and analyses confirmed that the accuracy of the selected method is 3 mm for the width and 3.6 mm for the height of the frame. Research material was collected from April to November 2016, with the use of Leica TS50 total station (1cc, 1 mm + 1 ppm), by one surveying team.
