32. Relevance Metric

The Relevance Metric is primarily used to compare the relevance (impact, currency and authority) of one entity relative to another, or relative to a specific stakeholder group. For example the Noteworthy BIM Publication Relevance Index (NBP-RI) compares the relevance of an NBP relative to other NBPs within and across markets. It can be also used to establish the relevance of an NBP to a group of practitioners, policy makers or researchers at a specific organizational scale - e.g. the relevance of NBIMS-US to contractors in the US (OrgScale 2), or relevance of PAS1192-4 to facility owners worldwide (OrgScale1). 

Relevance is measured using a five-level index (R0-R4). Below is an explanation of each level as applied within Paper B2:

  • R0 - Redundant: the NBP includes out-dated information which is no longer usable or useful
  • R1 - Relevant: the NBP is relevant, current and contains actionable information
  • R2 - Regarded: the NBP is highly-relevant, well-cited and well-used in comparison to other similar-topic NBPs
  • R3 - Recommended: the NBP is authoritative and impactful and considered a reference (among other references)
  • R4 - Requisite: the NBP is the most authoritative document covering a specific topic

Please note that the NBP-RI applies to all types of noteworthy publications. However, academic articles and scientific papers typically resort to more specialised metrics for establishing topical relevance and publications' overall impact.

30. Asset Hierarchy

Asset Hierarchy Across 3 Scales


This conceptual model (unpublished) is a taxonomic subdivision between three overlapping domains -  Building Information Modelling (BIM), Geographic Information Systems (GIS) and Product Lifecycle Management (PLM). The subdivision is based on four criteria (classes):

  • Asset Scale -  e.g. Built Environment or Building
  • Industry - e.g. Geospatial or Manufacturing
  • Applicable Acronym – e.g. BIM or PLM
  • Typical Unit of Measurement – e.g. Meters or Millimetres

Other criteria can be added to differentiate, qualify or compare the three domains
