Validation Rules Builder

Business Case

Problem Statement

Construction data quality challenges:

• Inconsistent naming conventions
• Invalid cost codes and WBS
• Missing or malformed data
• Non-compliant BIM elements

Solution

Rule-based validation engine using RegEx and logic rules to ensure data quality across construction systems.
