CEN Workshop on 'Geometric framework, coordinate systems and markers for BIM construction projects'

The aim of this proposed Workshop is to provide a standardised set of consistent guidelines for handling coordinate systems, official fixpoints, surveying points and markers used in construction projects and on site for BIM construction projects.

Digitalization and the Building Information Management - methodology (BIM) is spreading widely in the construction industry and will soon be the standard procedure for carrying out any kind of work related to construction. All data during the lifetime of a building will be generated, processed and handled digital and three-dimensional – also by the workers on site. Providing clear and practicable rules for the general geometric framework will make sure, that measurements and all other data from the different stakeholders in a construction project (in the office and on site) are easy integratable and consistent in the BIM platform.

 

This Workshop will create a CEN Workshop agreement (CWA), which provides guidelines for handling coordinate systems, official fixpoints, surveying points and markers used in construction projects and on site for BIM construction projects. Furthermore, the CWA will define a framework to enable an automated use of different coordinate systems and an automated calibration using physical markers. This includes a naming convention of different coordinate systems, common components of coordinate systems, marker and crosshair types, a naming convention for markers and a common digital interface for the read-out-data of markers.

 

The document will build on existing standards and conventions and will collate them where possible. The resulting CWA will be a valuable tool for BIM stakeholders, as construction companies, software providers for BIM visualization, planner engineers (architects, civil engineers, …), Geo-data capturers, surveyors, UXV operators, software providers dealing with BIM, GIS, and "on site superlocal" machines/devices/systems such as drones.

 

Any interested party can take part in this Workshop and/or comment on this draft project plan. Please send any requests to participate or comments by e-mail to christian.grunewald@din.de.

 

All those who have applied for participation or have commented on the project plan by the deadline will be invited to the virtual kick-off meeting of the Workshop on 2023-02-22, 09:00-12:30 Brussels time.
