I already developed a workflow to calculate quantities and building cost using archicad and excel,
ArchiCAD to model, schedule, extract data : I used Classifications, properties, schedules
Excel to collect data, calculate, and manage data in multiple formats,
Now, i want to improve, i looked into some posts here in the forum, informations aren't enough to build a robust solution based on IFC,
My idea is the following,
IFC psets will used as filters and data containers, for units, quantity / item description, calculated quantity, price per unit etc,
using IFC i can have access to data that can't be handled with properties and or classifications.
this data will be extracted using schedules, the rest of work in excel,
I want to know how to start exploring IFC and what type of limitations can i face in this workflow ?
If someone is interested, this thread would be a GREAT PLACE to exchange and develop the workflow.
Your timing of this post is perfect Lukas Oelmüller is doing a presentation next Friday as part of ARCHINTENSIVE - Session 17 on openBIM and cost estimation. He has developed processes using IFC for cost estimation. I suggest watching that session. https://www.skewed.com.au/events/archintensive-2023
