Brief definition
Cost group 410 (KG 410) under DIN 276 comprises drainage, water and gas installations — pipe routes, connections, and related components of building services.
Relevance for quantity take-off and BoQ
Items are often derived from lengths, counts, and diameter classes on services and floor plans. Traceable sources are decisive for VOB bills of quantities and variation review.
AIGO relevance
AIGO extracts geometry from 2D PDFs and exports structured quantities for technical cost groups, deterministically after scale calibration with standards references and source citations.
