Specification Basis

In order to design lightning protection systems and the related design of the protected volume of the air-termination system, it is necessary to have the scaled representation of the current building stock in a CAD file. If there are no such files or only insufficient 2D or 3D CAD files when commissioning a lightning protection design, these can be redrawn as 3D drawings using existing drawing documents in paper form and / or pixel scans of as-built drawings.

Requirements

1. Provision of drawings of the building / plant to be protected in non-editable electronic form or in paper form
2. Optional: Conducting a fee-based on-site as-built survey / project meeting (S03070)

Specification

Graphic representation of the building / plant to be protected in 3D CAD files
