Cwicr Quantity Matcher

What This Skill Does

The Cwicr Quantity Matcher is an intelligent BIM data processing tool designed to bridge the gap between building information models (BIM) and construction cost estimation systems. It automates the complex task of mapping raw element quantities from BIM files into standardized CWICR work items. By leveraging a rule-based engine and semantic matching algorithms, the skill interprets element categories, assigns them to appropriate cost codes, and validates unit measurements. It produces comprehensive, cost-linked Quantity Take-Offs (QTOs) that ensure high data integrity, significantly reducing the manual effort usually required to reconcile design quantities with procurement or budget items.

Installation

To integrate this skill into your environment, execute the following command in your terminal: clawhub install openclaw/skills/skills/datadrivenconstruction/cwicr-quantity-matcher

Use Cases

• Project Estimating: Automatically convert architectural Revit models into detailed cost breakdown structures.
• Quantity Reconciliation: Validate BIM-extracted material quantities against historical cost code benchmarks to detect potential modeling errors.
• Interoperability Standards: Harmonize project-specific naming conventions into corporate-standard CWICR codes for cross-project reporting.
• Procurement Preparation: Generate filtered, unit-converted material lists for vendor request-for-quotations (RFQs).

Example Prompts

1. "Map the exported floor and wall elements from the 'Design_Model_V4.csv' file to the CWICR database and output a list of any unmatched items."
2. "Perform a quantity take-off on the 'Mechanical_Systems_Model' and convert all square footage measurements to square meters using the internal conversion rules."
3. "Review the current cost-linked QTO for the concrete pour; flag any items where the confidence score is below 70% and require my manual validation."

Tips & Limitations

• Quality of Input: The skill relies heavily on clean BIM data; ensure that your export categories are properly mapped to Revit system categories before processing.
• Manual Review: While the tool provides confidence scores, always perform a visual spot-check on 'Medium' and 'Low' confidence results, as complex semantic relationships may sometimes require human judgment.
• Unit Standardization: Ensure your source units are consistent (e.g., all SI or Imperial) to maximize the effectiveness of the automated unit conversion engine. If a specific unit is not in the configuration, you may need to extend the conversion dictionary.
