A method and system for automatically creating Bills of Materials. A Building Information Model (BIM) electronic drawing is created on a 3D BIM program using Bill of Material standards. The BIM electronic drawing is exported, filtered and stored into a database with a cloud Software as a Service (SaaS) service on a cloud communications network The data is analyzed to produce in real-time a Bill of Materials accurate down to an individual piece level (e.g., stud, board, pipe, duct, etc.) for desired physical structures (e.g., houses, townhomes, multi-unit housing, etc.). The Bill of Materials includes a report produced in a standard and repeatable format, thereby reducing risk, reducing costs and ensuring a trackable level of quality for the builders of the desired physical structure and eliminating any need for estimating of any quantity, cost, installation time, installation cost or waste factor for any one of the plural physical components used to build the desired physical structure.
