MARKING ON SITE
DURATION: 2 DAYS

TRAINER: JÁNOS ALBERT

VISUELSE 3D TECHNICAL DIRECTOR

DAY 1
OBJECTIVE OF MARKING ON SITE

  • Methods and techniques of marking out – marking out land, buildings and structures, marking out structures within buildings, partitions
  • Partition walls, false ceilings, roofed structures, etc. – Traditional and instrumental techniques
  • Layout instruments – instruments in the world, principles of operation, instruments used for teaching
  • Relationship between model and layout plan – Overview of the process by which data is delivered to the field
  • Reference points – their role in the plotting plan and in the field. Marking requirements
  • Accuracy of plotting – Site global and local accuracy
  • Marking process – Visual inspection of the site, locating and checking base points, checking structural changes, marking axes using and checking base points, preserving marked points and/or lines, planning and logic of marking progression, tools required
  • Field conditions for setting out – minimum requirements for the site for the work to be carried out

DAY 2
PREPARATION, MARKING OUT

  • Tools – preparation of tools in the knowledge of the site
  • Field environment; Setting out
  • Instrument – unpacking, accessories, assembly, installation
  • Control panel (tablet) – software overview, scanning of setting plan, overview of functions
  • Basepoints (reference points) – locate and identify
  • Verification – registration to base points, verification process
  • Setting base axes – setting axis intersection points, precipitation
  • Registration – for base points, axes
  • Setting of structures – setting of points
  • Preservation of marked points – priming

FORM OF REFERENCE

The theoretical knowledge is checked and assessed by completing an online test.
The practical knowledge will be tested and matured by means of a series of homework exercises.
Prior to the assessment, the trainers will provide online consultation on request.
