Construction stakeout check with stake location, axis, elevation, photo and report
Stakeout value is proven when it can be checked later with target, found point, delta, elevation, photo and notes.
Field takeaways
- Target and found coordinates should be recorded separately.
- Stake, paint or mark should be photographed.
- Elevation reference should be noted.
- Tolerance depends on the work type.
- MapLab Survey connects stakeout checks to reports and exports.
Why it is checked
Days and machines pass between stake-out and execution. A peg that has shifted fifteen centimetres is invisible to the eye but not to the finished structure.
What is checked
Plan position, level and relation to the axis. All three can be wrong independently, so look at them separately.
What is recorded
Write the measured deviation, not just whether it passed. A record with numbers shows a trend; a tick box says nothing.
When it falls outside tolerance
Do not correct the peg quietly. Tell the site manager, record the deviation before and after, and keep both photographs. Points that repeatedly fall out usually indicate a problem with the control point itself rather than the work.

MapLab Survey handles RTK/GNSS point capture, drawing, area and volume calculations and coordinate conversion, then exports to DXF, KML/KMZ, GeoJSON, Shapefile, GeoPackage, NCZ or CSV. Capture, calculation and export work offline. Live NTRIP corrections and online basemaps need a connection.
