Who this course is for

What you will do
Read what the file declares (schema, units, storeys), group elements by type, take Qto_ base quantities (NetSideArea, NetArea, NetVolume, NetFloorArea, NetPerimeter), find a duplicated wall, apply measurement-rule thresholds the model does not know, and price the bill. You are the BIM coordinator and quantity surveyor of a main contractor's tender team. Every figure comes from the model and the case ledger, and every typical slip has a name.
