Vertigraph software performs quantity takeoffs directly in Microsoft Excel, increasing productivity while leaving a clear, concise audit trail. BidPoint is for paper plan takeoff using a large format digitizer tablet. BidScreen does not require a digitizer tablet—you simply open PDF, TIF, DWG, and other file types, then measure and color code the drawings with your mouse directly into any Excel workbook.
