Calculate quantities for all construction and architectural items

1. Drawing analysis The first step involves accurately analyzing engineering drawings and project technical specifications. 2. Use of specialized software Use software such as Revit to create a Building Information Model (BIM), which allows automatic quantity extraction, or AutoCAD for manual calculations. 3. Preparation of the bill of quantities and field verification The most important step to ensure that actual quantities match calculated quantities. A detailed Excel table is prepared including all items, with an additional column to compare the calculated quantity against the quantity actually executed on site. 4. Cost monitoring: Identifying differences between estimated and actual quantities. 5. Waste determination: Calculating the waste percentage for each material. 6. Budget control: Making precise decisions based on real data from the site.
