Quantity Take-Off (QTO) Report Generation
Overview
Based on DDC methodology (Chapter 3.2), this skill automates the extraction and grouping of quantities from BIM/CAD data. QTO is the foundation for cost estimation, scheduling, and project planning in construction.
Book Reference: "Quantity Take-Off и автоматическое создание смет" / "QTO and Automated Estimates"
"QTO Quantity Take-Off: группировка данных по атрибутам позволяет автоматически извлекать объемы и количества из BIM-моделей для расчета стоимости." — DDC Book, Chapter 3.2
5D BIM Concept
The QTO process is central to 5D BIM:
- 3D: Geometry (volume, area, length)
- 4D: Time (schedule integration)
- 5D: Cost (quantity × unit price)
