NBS (www.thenbs.com) is an integrated global platform for everyone involved in the design, supply and construction of the built environment.
The concept of the add-on is based on assigning the specification clauses that are referring to detailed data hosted and stored in NBS Chorus cloud-based platform. This workflow greatly expands flexibility of specification data editing (edited either from Archicad or NBS Chorus) without embedding redundant information in Archicad’s BIM model directly. Our approach preserves specification data integrity, “lighter” BIM model and at the same time allows for platform-independent delivery on both macOS and Windows.
NBS Chorus specifications are based on the clause-to-classification mapping concept. In order to facilitate NBS clause assignment to Archicad elements, the add-on will automatically classify the element based on a NBS clause. Any required classification system must be imported into Archicad prior to making a connection to any NBS specification.
