Brief definition
Cost group 300 (KG 300) under DIN 276 comprises the building structures of a project — from foundations and structural frame to non-load-bearing interior and exterior components, insofar as assigned to KG 300.
Relevance for quantity take-off and BoQ
In early design and tendering, quantities from drawings (areas, lengths, counts) are assigned to this cost group. A traceable geometry source (PDF → calibrated take-off) is a prerequisite for verifiable bills of quantities.
AIGO relevance
AIGO extracts geometry deterministically from 2D PDFs and structures exports for mapping to DIN 276 cost groups — without AI estimation of areas and lengths.
