New ZTV-W LB 215 (2012) for hydraulic concrete structures - including Eurocodes

The additional technical contract conditions for hydraulic (reinforced) concrete structures, ZTV-W LB 215, have been revised in 2012 due to recent experiences and knowledge, but also because of changing standards to the new Eurocodes. The ZTV-W LB 215 is based on the basis of structural engineering standards for design, manufacturing of concrete and execution of concrete structures as well as on the specific standard for concrete hydraulic structures. The article clarifies the main changes from the previous version of ZTV-W LB 215 which dates from 2004. Relevant changes are the hydraulic specific examples of exposure classes, the demands on the concrete concerning hydration, design and aftertreatment of construction and movement joints and regulations for surface concrete. The associated catalogue for the concrete construction works, StLk LB 215, has also been revised.
