The German Construction Contract Procedures (VOB) are the basis for public construction contracting and procurement in Germany and most major private projects. It combines legal provisions and technical rules.
The 2019 VOB complete edition replaced the 2016 edition as of 1 October 2019.
A supplement with the revised VOB/C General technical specifications in construction contracts (ATV) will be published in the second half of 2023.
The VOB is compiled, maintained and updated by the German Contract Awards and Contract Committee for Construction Services (DVA). It is published as a complete edition in Part A (DIN 1960), Part B (DIN 1961) and Part C (the “ATV” standards).
Beuth Verlag offers the following:
In November, the DVA (German Contract Awards and Contract Committee for Construction Services) decided to publish a supplement to the 2019 VOB complete edition. It is expected that this will be published in the second half of 2023. Accordingly, it can be understood that a new VOB complete edition will not be published next year.
The new supplement will contain the revised VOB/C “General technical specifications in construction contracts (ATV)”. Further details are expected to be clarified in the first half of 2023. It is already confirmed that the completely newly prepared DIN 18448 “Work on contaminated buildings and technical installations” will be published with the new supplement.
In general, the supplement is published when new versions of various Part C standards have been finalized, but Parts A and/or B cannot (yet) be adopted in new versions, or are subject only to marginal changes. The supplement is then valid in conjunction with the corresponding previous complete edition.
In concrete terms, this means the new Part C standards from the 2023 Supplement will replace the previous ones from the 2019 VOB complete edition. Those standards which have not been revised in VOB/C of the 2019 VOB complete edition will remain valid.
The 2019 edition of the VOB brings with it a number of changes.

DIN 18299 “General rules applying to all types of construction work”
In Clause 0 information on the safety and health plan, the Baustellenverordung and work relating to accident prevention has been included. in Clause 4, the subclause 4.2.10 on traffic safety measures outside the building site has been deleted.
DIN 18305 “Groundwater lowering”
The Normative references have been updated. A combined accounting of works (e.g. items x hours, items x days, items x weeks) and a differentiation between sump pumping and groundwater lowering by wells have been included in Clause 0. In Clause 1 the “Scope” has been revised. In Clause 4 additional associated tasks have been included.
In Clause 5 rules for deductions for pipe joints, fittings and valves have been revised in subclause 5.3.
DIN 18318 “Sett and slab pavements, and surrounds”
The Normative references have been updated. Clause 0 has been extensively revised. In Clause 1 the “Scope” has been revised. In Clause 3, reservations according to VOB/B (DIN 1961), § 4, Clause 3 are now dealt with, and new subclauses have been added. In Clause 4 additional associated tasks have been included. In subclause 5.3 the rules for deductions have been structurally revised.
DIN 18322 “Underground cable laying work”
The Normative references have been updated, a combined accounting of works (e.g. m/day, m/week, m/month etc) has been added to the revised Clause 0, and the Scope has been redefined (it now also applies to the laying of conduits, microtubes and microtube bundles). Clause 3 now takes into account conduits and ducts, and rules for the blowing in of cables, microtubes and microtube bundles are now included. In subclause 4.2 the list of special tasks has been extended.
DIN 18325 “Track works”
The Normative references have been updated. Clause 0 has been revised. In Clause 2 the rule that materials or components set aside shall not pass into the ownership of the contractor has been added.

Acceptance measurements after mounting switches and the provision of a construction supervisor for equipotential bonding are now associated tasks.
DIN 18332 “Natural stone work”
In DIN 18332 “Natural stone work”, the Scope has been made more precise.
DIN 18336 “Waterproofing”
DIN 18336 “Waterproofing” has been extensively revised. It has been brought in line with the new standards series DIN 18531 to DIN 18535. For this reason, the rules included in DIN 18338 “Roofing works” and DIN 18354 “Mastic asphalt works” on waterproofing have been deleted. DIN 18338 “Roofing works” thus has a different German title.
Normative references have been updated, and Clause 0 has been extensively revised, including the inclusion of combined accounting of works (e.g. m²/day, m²/week, m²/month). The “Scope” has been revised both in form and content. The sealing of carriageway deck slabs of bridges that form part of public highways is still not covered. Clause 3 has been restructured, and in Clause 4 additional associated tasks (e.g. the protection of components and equipment from soiling, and the levelling of height differences in scaffolding bases up to a levelling difference of 40 cm). In subclause 4.2 the list of special tasks, and in subclause 5.4 the list of individual provisions for the settlement of accounts have been extended.
Among other changes, information on post-construction waterproofing is now included in DIN 18336.
