Continuous Learning for Construction Automation

This skill enables automatic extraction of valuable patterns, solutions, and best practices from construction automation sessions to build institutional knowledge.

When to Use

Activate this skill:

• At the end of complex estimation sessions
• After solving non-trivial data processing problems
• When discovering new integration patterns
• After completing successful document processing
• When developing new automation workflows

Pattern Extraction Framework

1. Session Analysis

class ConstructionSessionAnalyzer:
    """Extract learnings from automation sessions"""

    # Categories of learnable patterns
    PATTERN_CATEGORIES = [
        'data_processing',      # Data transformation patterns
        'estimation',           # Cost estimation techniques
        'scheduling',           # Schedule optimization patterns
        'integration',          # API/system integration patterns
        'document_processing',  # Document handling patterns
        'quality_assurance',    # Validation and QA patterns
        'error_handling',       # Error resolution patterns
        'optimization'          # Performance optimization patterns
    ]

    def analyze_session(self, session_log: list) -> dict:
        """Extract patterns from session history"""

        patterns = {
            'successful_solutions': [],
            'error_resolutions': [],
            'optimization_discoveries': [],
            'integration_patterns': [],
            'reusable_code': [],
            'decision_rationales': []
        }

        for entry in session_log:
            if self._is_solution(entry):
                patterns['successful_solutions'].append(
                    self._extract_solution_pattern(entry)
                )

            if self._is_error_resolution(entry):
                patterns['error_resolutions'].append(
                    self._extract_error_pattern(entry)
                )

            if self._is_optimization(entry):
                patterns['optimization_discoveries'].append(
                    self._extract_optimization(entry)
                )

        return patterns

2. Knowledge Categories for Construction

#### 2.1 Cost Estimation Patterns

# Example learned pattern
pattern:
  name: "electrical_cost_adjustment_pattern"
  category: "estimation"
  context: "When estimating electrical work for high-rise buildings"
  problem: "Standard rates don't account for vertical transportation costs"
  solution: |
    Apply height factor multiplier:
    - Floors 1-5: 1.0x base rate
    - Floors 6-15: 1.15x base rate
    - Floors 16-30: 1.25x base rate
    - Floors 30+: 1.35x base rate
  confidence: 0.85
  source_sessions: ["session_2026_01_15", "session_2026_01_20"]
  validations: 3

#### 2.2 BIM Data Processing Patterns

pattern:
  name: "revit_level_extraction"
  category: "data_processing"
  context: "Extracting elements by level from Revit exports"
  problem: "Elements sometimes missing level association"
  solution: |
    1. First check 'Level' parameter
    2. If missing, check 'Reference Level' parameter
    3. If still missing, derive from bounding box Z coordinate
    4. Map Z ranges to known level elevations
  code_snippet: |
    def get_element_level(element: dict, levels: list) -> str:
        # Direct level parameter
        if level := element.get('Level'):
            return level

        # Reference level fallback
        if ref_level := element.get('Reference Level'):
            return ref_level

        # Derive from geometry
        z_coord = element['BoundingBox']['Min']['Z']
        return find_nearest_level(z_coord, levels)
  confidence: 0.92

#### 2.3 Integration Patterns

pattern:
  name: "procore_rate_limit_handling"
  category: "integration"
  context: "Syncing data with Procore API"
  problem: "API returns 429 Too Many Requests during bulk operations"
  solution: |
    Implement exponential backoff with jitter:
    1. Initial delay: 1 second
    2. Multiply by 2 on each retry
    3. Add random jitter (0-500ms)
    4. Max retries: 5
    5. Max delay: 32 seconds
  code_snippet: |
    async def procore_request_with_retry(url, data):
        delay = 1
        for attempt in range(5):
            try:
                response = await procore_api.post(url, data)
                return response
            except RateLimitError:
                jitter = random.uniform(0, 0.5)
                await asyncio.sleep(delay + jitter)
                delay *= 2
        raise MaxRetriesExceeded()
  confidence: 0.95

#### 2.4 Error Resolution Patterns

pattern:
  name: "cwicr_no_match_resolution"
  category: "error_handling"
  context: "CWICR semantic search returns no relevant matches"
  problem: "Query too specific or uses non-standard terminology"
  solution: |
    Resolution steps:
    1. Simplify query to core concepts
    2. Remove brand names and specifications
    3. Try alternative terminology (US vs UK terms)
    4. Expand search to parent category
    5. If still no match, flag for manual mapping
  examples:
    - original: "Kohler K-4519 wall-mounted water closet"
      simplified: "wall mounted toilet"
    - original: "Lutron Caseta wireless dimmer switch"
      simplified: "dimmer switch"
  confidence: 0.88

    for item in relevant[:5]:  # Top 5 suggestions
        pattern = item['pattern']
