DIN 18312
German construction contract procedures (VOB) - Part C: General technical specifications in construction contracts (ATV) - Underground construction work
VOB Vergabe- und Vertragsordnung für Bauleistungen - Teil C: Allgemeine Technische Vertragsbedingungen für Bauleistungen (ATV) - Untertagebauarbeiten
Overview
ATV DIN 18312 "Underground construction work" has been editorially revised by the German Committee for Construction Contract Procedures (DVA). Among other things, the references to VOB/A have been updated. This standard deals with the excavation and extraction of soil and rock, using sub-surface and cut-and-cover techniques, for the construction of underground cavities in soil and rock (such as adits, tunnels, caverns, shafts) which are not directly intended for the extraction of minerals. It includes the breaking, loading and haulage of soil and rock, the supporting of the cavity underground, and the collection, treatment and discharge of water up to the assigned discharge point. It also applies to supporting work in cases where this also serves to permanently line the cavities.
