Die Einführung der Homogenbereiche in den Tiefbau und die Auswirkungen auf die Projektbeteiligten

摘要

With the publication of the supplementary volume of the contracting and contracting procedures for construction work (VOB/C 2015) and the "general technical terms of contract" (AN standards), considerable changes have been noted in the field of underground engineering. The implementation presents the project participants with new challenges.The more than 50 soil and rock claws so far are now combined into homogeneous areas, depending on the discipline-specific application. As a result, the VOB/C should eliminate the recorded weaknesses, gaps and obsolete und redundant elements. The reform should develop a uniform system and privileges the cooperation of the project participants.For the client, the conversion involves more effort, which leads to additional costs. But those costs can be reduced through joint cooperation between the parties involved in the project. The contractor is in a better position to assess his performance now, so he can provide more realistic prices in terms of real costs. Planers and surveyors bear more responsibility and must work together more closely. The contractor stays responsible for the suitable ground handling. Dealing with the advertised homogenous areas requires an intense examination of the respective descriptions a corresponding expertise.
