bodenebene

Bodenebene is a German term used in architecture, construction, surveying, and design to describe a horizontal reference plane that corresponds to the finished floor level in a building or to the natural ground surface in outdoor contexts. It functions as a datum for vertical measurements, alignment, and installation.

In architectural and civil engineering contexts, the Bodenebene serves as the baseline from which heights such as wall heights, door thresholds, and stair dimensions are determined. It helps ensure consistency across layouts and sections, and it may be aligned with interior finished floors or with exterior ground interfaces depending on the project.

In accessibility and inclusive design, Bodenebene is considered when planning level transitions. Small differences in the Bodenebene between adjacent spaces or between indoors and outdoors can affect wheelchair access and foot traffic, so thresholds are often minimized or made ramp-friendly to maintain a continuous surface.

In surveying and geotechnical contexts, Bodenebene can refer to the ground surface used as a datum for topographic measurements, excavation planning, and soil assessments. The precise definition can vary by country, region, or discipline, and projects typically specify the reference plane in plans and specifications to avoid ambiguity.

Etymology: Boden means ground or floor, and Ebene means plane or level. Related terms include Bodenhöhe (ground height), finished floor level (FFL), and general architectural datum.
