The consortium of companies led by Egis and which includes Dassault Systèmes and B4 announced that they have been selected by the Ukrainian government to mobilize their expertise and experience for the reconstruction of urban areas in Ukraine. The project is supported by the French government with a grant from the French Treasury. The project will combine Dassault Systèmes’ 3DEXPERIENCE platform and Egis’ and B4’s construction engineering expertise, in a two-phase approach: a damage assessment and reconstruction cost analysis in the Chernihiv Oblast, followed by a strategic master planning for reconstruction in the city of Chernihiv. The first phase will consist of diagnosing the damages in the Oblast, to forecast the reconstruction costs and define which infrastructures to rebuild first. Dassault Systèmes’ 3DEXPERIENCE platform will support the collaboration and host all the information and analysis gathered by EGIS and B4 experts. Satellite data analysis will automatically detect and highlight impacted areas and will be cross-checked by inspections in the field to validate the calculations and the prioritization strategy. The second phase will involve building a virtual twin of the city of Chernihiv on the 3DEXPERIENCE platform. It will focus on optimizing how the city will be rebuilt including the design of new buildings and the organization of city transportation, infrastructure and other services. Stakeholders from diverse sectors will use the virtual twin to collaboratively test different scenarios involving parameters such as flooding risks, accessibility, transportation, land use, position of key urban assets, and existing water, heat, sewage and other infrastructure networks. In parallel, they will source information from existing documents and city departments to ensure that the needs and expectations of inhabitants in each neighborhood, the vision of elected officials, and economic and social development challenges are all taken into account. Throughout the project, all information collected will be fed into the virtual twin of the city to enable the partners to collaboratively build the city master plan.
