I.4 Erection Grid, coordinates & Erection Zones

Component positions are described in site language (G/13, A/1–3, D–E/2–3). The site coordinate system is proposed and approved – the original IFC coordinates are never changed automatically.

What it does

Reads the grid (IfcGrid) and elevations from the IFC, or creates / edits them manually; check points and deviations before confirmation.
Zones by grid range and elevation: number of components, weight and % delivered / installed / accepted.
