Introduction 🌟
The construction and real estate industries are entering a new era with Digital Twins and Building Information Modeling (BIM).
While BIM has already transformed how architects, engineers, and contractors design and collaborate, Digital Twins take this a step further by connecting physical assets with real-time digital models.
👉 Together, BIM + Digital Twins empower stakeholders to design smarter, build efficiently, and manage buildings with real-time intelligence.
What is a Digital Twin? 🤖🏗️
A Digital Twin is a virtual replica of a physical asset (like a building, bridge, or city).
It doesn’t just mirror geometry — it also connects real-time data from IoT sensors, AI, and analytics.
✨ Imagine a building that “talks” to you — reporting energy consumption, HVAC efficiency, occupancy patterns, and predictive maintenance needs.
Digital Twin = BIM Model + Real-Time Data + AI + IoT
