Checklist: Leveling and layout

§Before you set up the instrument

• 01Do you have the right dimensions and measurements from the drawing?
• 02Is the instrument checked and in order?
• 03Have you chosen the right measuring instrument for the task (laser, level telescope, GPS)?
• 04Is there clear line of sight to the points you need to measure?

§During sale.

• 01Check instrument accuracy with simple verification
• 02Mark elevations, falls and lines according to the drawing — not by eye
• 03Double-check critical points (e.g. drain slope and corners)
• 04Clearly mark set points so they are not destroyed along the way

§Documentation

• 01Note line and area levels in the digital measuring log
• 02Save the measurements so they can be found again in case of doubt later
• 03Inform the crew of the surveyed heights and gradients before work continues
