AI-Powered Construction Safety & Progress Monitoring
Computer vision and predictive analytics for construction site safety, progress tracking, and risk management at scale
Overview
BuildVision manages large-scale infrastructure projects including highways, commercial complexes, and industrial facilities across 200+ active sites. We built an AI platform that monitors safety compliance in real-time via CCTV, tracks construction progress against BIM models using drone imagery, and predicts project risks weeks before they materialize.
The Problem
Construction is one of the most dangerous industries, with safety incidents causing human tragedy and project delays. Traditional safety management relies on periodic manual inspections that miss violations happening between checks. Progress tracking is equally manual, with site managers spending hours compiling reports instead of managing construction.
Key Challenges
Reactive Safety Management
Safety officers could only inspect each zone once daily. PPE violations went undetected for hours. Near-miss incidents weren't captured systematically. Safety data was fragmented across paper forms, making trend analysis impossible. Incident response was always after-the-fact.
Progress Reporting Nightmare
Site managers spent 3-4 hours daily compiling progress reports. Information was always 24-48 hours stale by the time leadership saw it. No way to compare actual progress against planned schedules automatically. Drone imagery was collected but not analyzed systematically.
Siloed Data Across 200+ Sites
Each site operated as an island with its own reporting formats. Regional managers had no real-time visibility into their portfolio. Best practices weren't shared across sites. Executive dashboards were updated weekly at best.
Unpredictable Delays and Cost Overruns
By the time delays were identified, recovery options were limited. Weather impacts weren't factored into schedules proactively. Resource conflicts across sites weren't visible until they caused problems. No early warning system for emerging risks.
How We Built It
Safety Monitoring Infrastructure
Deployed edge AI devices at 200+ sites connected to existing CCTV networks. Trained custom computer vision models for PPE detection (helmets, vests, harnesses), zone violations, and unsafe behaviors. Built real-time alert system with escalation workflows to safety officers and site managers.
Progress Tracking System
Integrated with BIM (Building Information Modeling) systems to create 4D digital twins of each project. Implemented automated drone imagery analysis comparing as-built status against planned models. Built progress dashboards showing completion percentages by building element and zone.
Predictive Risk Analytics
Developed ML models analyzing historical project data to identify patterns preceding delays and incidents. Integrated weather forecasts, resource schedules, and supply chain data. Created 14-day risk forecasts with recommended mitigation actions.
Enterprise Rollout & Training
Deployed across all 200+ sites in phased rollout over 12 weeks. Trained 500+ site personnel on the platform. Established safety and project management workflows integrated with existing processes. Built executive dashboards for portfolio-level visibility.
Solution Highlights
Real-Time PPE Compliance
Computer vision monitors all camera feeds 24/7, detecting PPE violations within seconds. Instant alerts sent to supervisors with violation photos. Compliance rates tracked by zone, shift, and contractor for accountability.
Automated Progress Tracking
Weekly drone imagery automatically compared against BIM models. AI identifies completed, in-progress, and delayed elements. Progress reports generated automatically, freeing site managers for actual management.
Predictive Risk Intelligence
14-day forecasts predicting potential delays, safety risks, and resource conflicts. Models analyze weather, supply chain status, historical patterns, and current progress. Early warnings enable proactive intervention before problems materialize.
Portfolio-Wide Visibility
Executive dashboards showing all 200+ sites in real-time. Drill-down from portfolio to region to site to specific zone. Standardized KPIs enable cross-site benchmarking and best practice identification.
Technical Deep Dive
The safety monitoring system uses a custom-trained YOLOv8 model optimized for construction environments, achieving 97% accuracy on PPE detection. Models run on NVIDIA Jetson Orin devices at each site for <50ms inference and data privacy. Progress tracking uses photogrammetry to convert drone imagery into 3D point clouds, then aligns them with BIM models using ICP (Iterative Closest Point) algorithms. Deviation detection uses change detection networks comparing current state against planned state. The risk prediction system uses an ensemble of gradient boosting (for structured data) and LSTM networks (for time-series patterns), trained on 5 years of project data including 10,000+ historical delays and their root causes.

“We went from finding out about safety issues after they became incidents to preventing them before they happen. The AI sees what 50 safety officers couldn't.”
