One of the tasks in WP4 “Development of the systemic renovation support tool (RenoBIM)” is dedicated to "Architecture of the RenoBIM Tool”. Recently second achievement - “Building template modeller” - has been accomplished.
This task began with a study of all the various devices and technologies available today, then opted to use “classic” total stations for comparison with 3D laser scanners.
In July we planned a first surveying test of the demo building to be renovated by POBI in La Charité-sur-Loire with three different total stations. The points and lines collected were entered into Dietrich’s CAD tool, firstly for comparison’s sake, then to define a “better” methodology for surveying with such devices. Better, because the result of the first test wasn’t entirely satisfactory.
The second stage involved doing a full survey of the building with a 3D laser scanner in October. As previously identified, the special requirements for such a building regarding data capture and 3D modelling concern the high level of accuracy required to fit prefabricated modules to facades, with absolutely no need to cut walls or alter modules.
The report on this task is designed to serve as a guidebook for the entire process, from initial contacts and contracting with a 3D-scan service provider to a full range of checks of deliverables, and final checking of the IFC file, prior to further progress with the RenoBIM tool.
All the deliverables and the various tools and software used by the provider and end-users have been defined to give the best overview of the whole process described in the diagram above.
