CivilAI Sentinel is a next-generation structural health monitoring tool built entirely in Google AI Studio using the "Vibe Coding" workflow. It leverages the advanced multimodal reasoning capabilities of Gemini 3 Pro to act as a pocket structural engineer, democratizing safety assessments for aging urban infrastructure.
Structural failures in densely populated cities are often preceded by visible warning signs that go unnoticed by non-experts. Professional inspections are expensive, reactive, and scarce. Homeowners often cannot distinguish between:
- A harmless shrinkage crack.
- A dangerous foundation settlement.
- Critical rebar corrosion.
CivilAI Sentinel bridges the gap between raw visual data and expert engineering verdict. Instead of simple object detection, it uses Gemini 3 Pro to perform Forensic Analysis:
- Analyze video frames/images of building elements.
- Reason about the physics of the defect (e.g., "stair-step pattern implies soil shifting").
- Diagnose the root cause and assign a Safety Risk Score.
It doesn't just flag damage; it explains why it happened.
- Stair-Step Cracks → Diagnosed as Foundation Settlement.
- Diagonal Cracks → Diagnosed as Shear Stress.
- Rust Stains → Diagnosed as Internal Corrosion.
- Spalling & Exposed Rebar: Identifies advanced concrete degradation.
- Efflorescence: Detects hidden water seepage through salt deposits.
- Thermal/Shrinkage Cracks: Correctly identifies low-risk surface issues to prevent false alarms.
Generates an instant report card:
- 🟢 Low Risk: Monitoring recommended.
- 🟡 Medium Risk: Professional consult advised.
- 🔴 Critical Risk: Immediate evacuation/repair required.
This project was created without writing traditional boilerplate code. Using Google AI Studio's Build capabilities, I engineered specific system instructions to transform Gemini 3 Pro into a civil engineering expert.
The Tech Stack:
- Model: Gemini 3 Pro (Experimental)
- Platform: Google AI Studio (Web Runtime)
- Logic: Multimodal Prompt Engineering & Chain-of-Thought Reasoning
This project is a submission for the Google DeepMind - Vibe Code with Gemini 3 Pro competition.
"CivilAI Sentinel proves that Generative AI can solve physical-world safety problems, moving us from reactive disaster management to proactive prevention."
