Soil Orientation Values

Soil benchmarks (Section 196(1) of the Building Code) are average position values of the soil for a majority of land within a defined area (soil benchmark zone), which largely correspond according to their land characteristics, in particular by type and degree of usability, and for which essentially the same general value ratios exist. They are related to the square metres of land area of a plot with the associated land characteristics (soil indicative land). The soil benchmarks are decided on a regular basis every two years by the Thuringian expert committees for land values and published in the Land Orientation Information System Thüringen (BORIS-TH). At the request of a municipality, for individual urban development areas (development areas and remediation areas that are not implemented in the simplified procedure), soil benchmarks are also decided on different reference dates.
