Until only a few decades ago, navigation meant paper maps, experience and a certain degree of improvisation. If you took a wrong turn, you stopped, reoriented yourself and continued your journey. A similar picture long characterized construction sites: paper drawings, manual progress markings and decisions based on experience and intuition. Today, modern navigation systems provide an up-to-date situational overview within seconds — with real-time information on traffic, detours and arrival times. They are no longer simply route guidance but dynamic process management in real time. This raises a central question: Do we already have a comparable navigation system on our construction sites — or are we still largely managing construction progress using analogue plans? Max Bögl already demonstrates in practice what such a digital situational picture can look like in construction.
