Brief definition
Cost group 100 (KG 100) under DIN 276 comprises preparatory site measures — work on the plot before the main construction works begin, insofar as assigned to this group.
Relevance for quantity take-off and BoQ
Quantities often derive from site plans and earthworks drawings (areas, volumes, lengths). Traceable geometry sources matter for bills of quantities and cost tracking.
AIGO relevance
AIGO supports calibrated quantity take-off from 2D PDFs — especially for geometry-driven groups. KG 100 is linked to the overall cost structure together with building construction groups.
