ACCA software’s protagonists at the Berlin Summit

ACCA software confirms its presence at the event as a Silver sponsor and, during the three days of the Summit, ACCA software will be a key player with:

• usBIM.geotwin – finalist in the Awards in the Operations category: the solution allows for the creation and management of georeferenced digital twins, with an approach that integrates GIS and BIM into a single platform for asset control and management in the territory;
• usBIM.sustainability – finalist in the Awards in the Technology category: an application designed to support designers and companies in assessing and reducing the environmental impact of constructions;
• usBIM.ifc5 – official presentation in the Technical Room of a cutting-edge technology that contributes to the testing and implementation phase of the new standard, offering a complete set of advanced features for the visualization and management of digital models in IFCX format. Now available in the ifcx_alpha version for managing and visualizing IFC5 models.

ACCA software’s contribution to the implementation and validation of the IFC5 standard

ACCA software, in addition to actively participating in the development of the new IFC5 standard, is contributing to the testing phase by providing its technology for the online visualization of IFC5 data.

usBIM.ifc5, an application dedicated to managing IFC5 models of any size, allows users to:

• convert old IFC files into the new IFC5 format (.IFCX);
• explore workflows emerging from the USD ecosystem;
• continuously adapt to the evolution of the IFC5 standard, integrating feedback from the working group.

usBIM.ifc5 is part of the broader usBIM ecosystem, which currently supports integrations with openBIM^® standards such as bSDD, IDS, BCF, and others, ensuring full compliance with openBIM^® workflows and offering a wide range of additional features. Future updates will introduce these integrations in usBIM.ifc5 as well.
