Specification Extractor for Construction

Overview

Extract structured data from construction specification documents. Parse CSI MasterFormat sections, identify requirements, submittals, product standards, and compile actionable data for estimating and procurement.

Business Case

Automated spec extraction enables:

• Faster Estimating: Quickly identify scope and requirements
• Procurement Accuracy: Extract exact product specifications
• Submittal Tracking: Identify all required submittals
• Compliance Checking: Verify specs against standards
