From 2D Drawings to IFC: How a Quantity Surveyor Replaced His Workflow with openBIM | openBIMvoice 09

from BIMvoice · host Petru Conduraru

In the ninth episode of openBIMvoice, I talk with Stefano Verugi, a quantity surveyor who took an unusual path into openBIM. Instead of starting with IFC models from designers, he began by converting 2D drawings into IFC models himself so he could extract quantities in a more structured and reliable way. Stefano works on railway and infrastructure projects in Ghana and has rebuilt his workflow around IFC, Bonsai BIM, and structured information. We talk about quantity takeoff, data analysis, open source tools, SketchUp, Blender, and why IFC can give quantity surveyors much more than geometry. The core idea is simple. When a quantity surveyor works with structured model data instead of disconnected drawings and spreadsheets, the job becomes less about chasing quantities and more about analyzing real project information. What we discuss: From 2D Drawings to IFC. How Stefano moved from traditional quantity takeoff into IFC based workflows by modeling from drawings and extracting quantities from structured data. Why the Old Workflow Breaks. Why manual takeoff from drawings is slow, repetitive, and fragile when project information changes. Better Accuracy and Better Control. How building the model himself helps Stefano verify drawing quality, spot missing information, and produce more reliable quantities. openBIM for Quantity Surveyors. Why IFC is not just useful for designers and coordinators, but also a strong workflow foundation for QS work. Structured Data Over Spreadsheet Chaos. Why properties, quantities, classifications, and standard naming structures give Stefano a better system than disconnected Excel workflows. Learning openBIM the Hard Way. What made the transition difficult at the start, what helped him push through, and why community support matters.
