Construction Use Cases

Adaptive Sentience enables automated workflows for construction sites with offline capability and compliance enforcement.

Industry Challenges

Construction sites face unique operational challenges:

  • Unreliable connectivity (remote sites, underground work)
  • Mobile workforce (crews move between sites)
  • Strict compliance (OSHA, safety regulations, insurance)
  • Heterogeneous systems (tablets, phones, drones, sensors)
  • Change orders (frequent workflow updates)

Core Use Cases

1. Daily Site Inspection Reports

Problem: Paper-based inspections are slow, error-prone, and hard to audit.

Solution: Automated workflow with mobile data collection.

Workflow: 1. Inspector uses tablet to capture site photos 2. Checklist validated against schema 3. Safety violations detected automatically 4. PII redacted (worker names, IDs) 5. Report generated and sent to superintendent 6. Audit trail created for compliance

Implementation:

{
  "workflow_id": "daily_site_inspection",
  "steps": [
    {
      "step_id": "capture_photos",
      "tool_name": "capture_photo",
      "tool_args": {"count": 10, "gps_tag": true},
      "target": {"kind": "capability", "required_capabilities": ["hardware:camera", "hardware:gps"]}
    },
    {
      "step_id": "validate_checklist",
      "tool_name": "validate_schema",
      "tool_args": {
        "data": "{{input.checklist}}",
        "schema": "osha_daily_inspection_v2"
      }
    },
    {
      "step_id": "detect_violations",
      "tool_name": "safety_violation_detection",
      "tool_args": {
        "images": "{{steps.capture_photos.output.images}}",
        "checklist": "{{steps.validate_checklist.output.data}}"
      }
    },
    {
      "step_id": "redact_pii",
      "tool_name": "pii_redact",
      "tool_args": {
        "text": "{{steps.detect_violations.output.violations}}"
      }
    },
    {
      "step_id": "generate_report",
      "tool_name": "pdf_report_generator",
      "tool_args": {
        "template": "daily_inspection",
        "data": {
          "photos": "{{steps.capture_photos.output.images}}",
          "checklist": "{{steps.validate_checklist.output.data}}",
          "violations": "{{steps.redact_pii.output.redacted_text}}"
        }
      }
    },
    {
      "step_id": "route_report",
      "tool_name": "send_email",
      "tool_args": {

}

Benefits: - ✅ Works offline (no cellular required) - ✅ Automatic OSHA compliance checking - ✅ PII protection built-in - ✅ Complete audit trail - ✅ Reduces inspection time by 60%

2. Change Order Documentation

Problem: Change orders require documentation, approvals, and cost tracking.

Solution: Automated workflow from field capture to billing.

Workflow: 1. Foreman photographs change condition 2. Voice note captured and transcribed 3. Scope compared against original contract 4. Cost estimate generated 5. Approval routed to project manager 6. Billing updated automatically

Implementation:

Compliance & Audit

OSHA Compliance

  • Automatic OSHA 300 log updates
  • Safety violation detection
  • Incident reporting workflows
  • Training record tracking

Insurance Requirements

  • Photo documentation with timestamps
  • GPS tagging for location verification
  • Audit trails for claims
  • Automatic package generation

Contract Compliance

  • Change order tracking
  • Scope validation
  • Cost documentation
  • Approval workflows

ROI Metrics

Track these metrics to measure value:

  • Inspection time reduction: Target 40-60% decrease
  • Change order approval time: Target <24 hours
  • Safety incident response time: Target <1 hour
  • Defect resolution rate: Target >90% on time
  • Compliance violation rate: Target 0%

Best Practices

1. Start with One Workflow

Begin with daily inspections, prove value, then expand:

  1. Week 1-2: Daily site inspections
  2. Week 3-4: Safety incident reporting
  3. Week 5-6: Change orders
  4. Week 7+: Quality control

2. Train Key Personnel

  • Site superintendent (gateway management)
  • Foremen (workflow execution)
  • Safety officer (incident reporting)
  • Office staff (reporting and analysis)

3. Offline-First Mindset

  • Don't assume connectivity
  • Cache reference data locally
  • Set reasonable sync intervals
  • Monitor queued workflows

4. Continuous Improvement

  • Review audit logs weekly
  • Adjust workflows based on feedback
  • Add new tools as needed
  • Monitor compliance metrics
