FACADES OF THE NEW MATERNITY WARD IN FIRULE, SPLIT

  • Survey was conducted in order to install glass facade, so it was very important to have an accurate geometry of the bearing structure.
  • Scanning resolution was 1 cm.
  • From measurement data horizontal and vertical cross-sections at given positions were generated.
  • As a result, deformations of the bearing structure were noticed which enabled the designer to avoid glass bursting after instalment of the facade, thus avoiding extended material damage.

CALCULATION OF THE CONCRETING SURFACE, THICKNESS AND VOLUME OF THE BUILT-IN CONCRETE WHEN FOUNDING THE BUILDING

  • Scanning of the ground plane prior to concreting was done, as well as concrete sheet on the same area.
  • Based on of measuring data polygonal models of both surfaces were generated.
  • Automatised comparison of the ground and concrete surfaces resulted in concrete thicknesses and their distribution over the given area.
  • In the tabulation, concrete thicknesses are shown as errors, or concrete surface from ground surface deviations.
  • This kind of graphical displays offers a very simple, visual inspection of thickness of the concrete layer deposited on the ground base, which enables easier decision-making on further interventions.
  • This principle of comparing two surfaces is also used when monitoring shift on any structure (bridges, dams, embankments, etc.)
  • Since in both cases we have the same reference plane to which volume is calculated, by subtracting the resulting volume we will get the exact volume, or cubage, of the built-in concrete.
