Anomaly Detection

Catching issues before they become problems can save time, money, and reputation. Anomaly detection is your AI-powered watchdog, constantly monitoring for the unexpected.

What is Anomaly Detection?

Anomaly detection continuously analyzes your project data in real-time and compares it against historical "normal" data to establish a baseline of expected behavior and identify deviations from this baseline.

This process involves:

  1. Data Ingestion: Collecting and preprocessing diverse data sources from your projects.
  2. Feature Extraction: Identifying key characteristics or "features" in the data that are most relevant for detecting anomalies.
  3. Model Application: Applying the trained AI model to new data to detect anomalies.
  4. Threshold Setting: Determining the level of deviation that constitutes an anomaly, often using statistical measures or machine learning-based decision boundaries.
  5. Alert Generation: Flagging detected anomalies and generating alerts for human review.

The AI system can detect both point anomalies (individual data points that are unusual, such as a sudden spike in material costs) and contextual anomalies (data points that are unusual in a specific context, such as a subcontractor's productivity rate that seems normal but is significantly lower compared to similar projects in the past).

These capabilities allow the system to identify a wide range of potential issues, from obvious discrepancies to subtle, context-dependent irregularities.

I mostly implement Anomaly Detection for these purposes:

1. Financial Irregularity Detection

Why?

  • Spot unusual patterns in project financials to detect errors or fraud early
  • Identify cost overruns or underruns early in the project lifecycle
  • Detect unexpected changes in supplier pricing or subcontractor billing

2. Safety Data Analysis

Why?

  • Identify unusual patterns in safety data
  • Detect deviations from safety protocols in real-time
  • Recognize equipment usage patterns that could lead to failures or accidents

3. Quality Control Enhancement

Why?

  • Detect deviations from quality standards in construction processes
  • Identify unusual patterns in material usage or performance
  • Spot inconsistencies in inspection reports or quality assurance data

4. Schedule Optimization

Why?

  • Identify unexpected delays or accelerations in project timelines
  • Detect unusual patterns in task completion rates or resource utilization
  • Spot potential bottlenecks or inefficiencies in project scheduling
