🏗️ oculai erfasst automatisch den Baufortschritt und Arbeitsprozesse im Rohbau. Dafür nutzen wir Krankameras, deren Bilddaten täglich per KI ausgewertet werden. So entstehen objektive Einblicke darüber, welche Arbeiten stattgefunden haben, wie weit sie im Terminplan fortgeschritten sind und wo es zu Verzögerungen oder Leerlauf kommt. Generalunternehmer nutzen oculai, um ihre Projekte besser zu steuern: 📅 sie steuern Termine im automatischen Soll-Ist-Terminplan, 📈 sie schaffen Transparenz über Produktivität und erhalten Beschleunigungsvorschläge, 👁️ und sie erhalten durch Live-Streams aus der Vogelperspektive eine lückenlose Dokumentation ihrer Projekte. 👉 Kurz gesagt: oculai hilft GUs, Rohbauprojekte planbarer, schneller und effizienter umzusetzen. --- English: oculai automatically tracks construction progress and activities in shell construction. To do this, we use crane cameras whose image data is evaluated daily by AI. This provides objective insights into what work has been done, how far it has progressed in the schedule, and where delays or idle time occur. General contractors use oculai to better manage their projects: 📅 they manage deadlines in the automatic target/actual schedule, 📈 they create transparency about productivity and receive suggestions for acceleration, 👁️ and they obtain complete documentation of their projects through live streams from a birds eye view. 👉 In short, oculai helps GCs to implement structural shell projects in a more predictable, faster and more efficient manner.
