CEN/WS CSBIM - Geometric framework, coordinate systems and markers for BIM construction projects (Coordinate Systems at BIM).

This document is applicable to construction processes where the usual surveyor’s control points are to be used not only for geometry control, but other applications such as laser scanning, localization of autonomous vehicles, photogrammetry, or VR/AR applications.
It provides a framework for making accurate survey point information available to digital applications and other trades. This includes the layout of markers, a naming convention for markers and a common digital interface for the read-out-data of markers.
The document builds on existing standards and conventions and collates them where applicable.
The document is intended to be used on construction sites and in existing buildings by planners (architects, civil engineers,…), surveyors, construction companies, software providers, UXV operators, BIM stakeholders, and on site machines/devices/systems.
The survey point information may be utilised not only during the construction but also during maintenance throughout the life of the facility.
