Searching for a guidance to define information requirements for your BIM Projects?

Our Information Requirements Catalogues at BIMQ Platform could be the best starting point for you!

An Information Requirements Catalogue is a structured specification that assures a common understanding for all project stakeholders about who delivers what, when, why and how. This catalogue could be used as an addendum to Employer’s Information Requirements (EIR) or BIM Execution Plan (BEP) to provide a clear and detailed definition of level of information need for each BIM deliverable.

The concept of level of information need was first introduced at ISO 19650 series which represents the framework for specifying the extent and granularity of information. Since the introduction as Level of Detail (LOD) in 2004, many metrics have been emerged and used in the industry for this purpose. In our catalogues which have been evolved over the time, two metrics are used for the definition of information requirements:

  • Level of Geometrie (LOG) for geometrical content

  • Level of Information (LOI) for alphanumerical content

BIMQ – first database for definition of information requirements

BIMQ is an Information Requirements Database that provides the flexibility of using any metric for the definition of level of information need for each BIM deliverable. Since 2013 we are using BIMQ to develop, update, share and archive Information Requirements Catalogues for construction and infrastructure projects. Released as a commercial product at BIM World 2017, BIMQ has been used by public clients, building authorities, contractors and planners.

BIMQ focuses not only on the standardized definition of information requirements, but also transferring these requirements into software using automated routines. After the information requirements are defined property templates or checking rules can be generated and directly imported in model authoring tools such as ARCHICAD or Revit, and model checking software such as SimpleBIM and Solibri Model Checker.

Check out our sample Information Requirements Catalogue!

This catalogue involves the following modules:

  • Project Phases
  • Actors
  • BIM Use Cases
  • Discipline Models
  • Model Elements
  • Element Geometries
  • Element Properties

These modules are then compiled to define the information requirements on discipline models for each phase, actor and use case as below:
