Direct connection between Revit and Arquimedes to obtain quantities from a BIM model
The MedBIM – Revit plugin allows you to obtain quantities from a Revit BIM model and, thanks to the "Bills of quantities of BIM models" module, incorporate them into an Arquimedes bill of quantities.
The measurement can be incorporated into a new Arquimedes bill of quantities or into an existing one (pre-designed bill of quantities). The two scenarios are presented below:
- No prior bill of quantities exists
The project modelled in Revit is linked to a new Arquimedes project, which, in turn, will be associated with the CYPE Cost database or with any other database that Arquimedes can read. In Arquimedes, the items representing each element modelled in Revit are introduced and linked. The measurement is generated using the information extracted from the Revit model. In this way, the bill of quantities structure in Arquimedes is gradually formed.
If there are construction elements with keynotes that match the item codes of the associated database, these are automatically entered into the bill of quantities, linked to the corresponding construction element, and their quantities generated.
- A prior bill of quantities exists
The Revit project is linked to a prior bill of quantities and its items are related to each element modelled in the BIM program. This generates the measurement for each item with the information extracted from the Revit model.
If there are construction elements with keynotes that match the code of certain items in the bill of quantities, these are automatically linked. If the keynote code does not exist in the bill of quantities but does exist in the associated database, it is automatically added to the bill of quantities, linked to the corresponding construction element, and its measurement is generated.
Normally, the prior bill of quantities (also called the pre-designed bill of quantities) is the one used to inform the developer and obtain the property feasibility study. Once linked to the project modelled in Revit, it can be modified or completed with new items if there are elements modelled in Revit that were not foreseen in that bill of quantities; or conversely, elements present in the prior bill of quantities but not yet modelled may be modified or added in Revit. In this way, the Revit model also minimises omissions and item-related errors.
Furthermore, considering that a building project may be generated using several Revit projects (architecture, structures, services), these can be linked to the same Arquimedes bill of quantities using the Arquimedes "Consolidation of bills of quantities" module.
