Layout from wrong gridline or column line
Confirm the gridline/column line before layout. One wrong control line can shift the whole run.
Watch out
- Do not start layout from an unverified wall, column, or line.
Check
- Find the correct grid bubble.
- Check dimensions from two directions when possible.
- Compare to columns/walls/control lines in the field.
- Snap/mark from verified control points.
- Ask before layout if the building control is unclear.
