Introduction
In the "Bill of quantities" tab, users have tools for generating and managing the bill of quantities of the system analysed by each program. Here, users can extract quantities in the model and generate real items based on this information. This process is carried out by means of a correspondence system between the elements measured on the analysis model and the bill of quantity concepts (mapping). This equivalence is stored in a local or network directory so that it can be progressively expanded and used in future projects.
Some of the applications integrated into the Open BIM workflow show the "Bill of quantities" tab in the toolbar. The Open BIM programs that currently have this tab are CYPEPLUMBING, CYPELEC, CYPEHVAC or CYPEFIRE, among others.
The "Bill of quantities" tab is also included in the Open BIM Quantities program. Unlike the rest of the applications that include this tab, Open BIM Quantities allows users to extract quantities from BIM models defined using the IFC standard (in the "Quantities of the BIM model" tab). Once the quantities have been extracted, the process to generate the bill of quantities in Open BIM Quantities is carried out in the "Bill of quantities" tab, in the same way as in the rest of the Open BIM applications that include this tab.
