Erection design steps

The German licensing procedure is usually a step-wise approach as indicated in Table 3.2. It means that the first step generally comprises an overall approval of the safety design concept of the plant, and is required for excavation of the pit, erection of a certain part of the main buildings, essentially the base mat and the walls up to zero level, and a so-called "preliminary positive overall appraisal" of construction, erection, and operation of the whole plant. This appraisal is explicitly required by the Atomic Energy Act. 

In the next step the most important parts of the building will be planned. This includes the base plate on which the plant will be erected, the vertical main columns and the horizontal platforms in the different floors. The base plate can be designed as a flat cuboid. This requires the outer dimensions (length, width and thickness of the concrete slab) and the place where the plate is positioned to... 

Take steps to ensure that there wiii be information avaiiabie reiating to the design use and iimitations of any articie used at work. The information shouid inciude any instructions on how to use the articie safeiy. it shouid aiso detaii where appiicabie how to instaii, handie, erect and dispose of the items to ensure they remain safe and fit for purpose and any residuai risks inherent with the items have been reduced to the iowest ievei reasonabiy practicabie. This information must be provided to aii persons those who may require it. 

Design, manufacture, erection and commissioning of functional groups can be carried out in steps and largely independent of each other. It is possible to co-ordinate the individual steps to optimise scheduling and technological details.
