Information exchange in the life cycle
Building information modelling provides a digital technology for describing and displaying information required in the planning, design, construction and operation of constructed facilities. Increasingly, this modelling approach is expanding to encompass all aspects of the built environment, including civil infrastructure, utilities and public space and all disciplines. These are collectively referred to as construction processes. This approach to managing information brings together the diverse sets of information used during the life cycle of the built environment into a common information environment - reducing, and often eliminating, the need for the many types of paper documentation currently in use.

This approach is commonly referred to as BIM (building information modelling, reflecting its initial application in the architectural domain), while the same acronym is used to refer to the product of the process, the information model itself, or BIM (Building Information Model).

The introduction of BIM leads to an increasing need to describe the information deliveries (data drops) on the interface between actors in the process. In practice these data drops are a combination of data sets according to multiple formats and differing standards, as well as proprietary formats. Available BIM standards are not equipped to support this practical situation.

This standard provides an information model and exchange format by means of a container for BIM related data.

The importance of this standard is the integration of open data based on differing standards (as well as proprietary formats, where needed), but packaged up in a way that makes explicit links between multiple representations of the same object. For example, a construction component such as a road abutment may be defined in a BIM library (as a type), linked to text specification or meta data, and include a 3D representation in a IFC file and/or a 2D representation in a GIS file.

The current version is COINS 2.0

What is Coins: General Concepts

  • Essentials; In the Essentials section the general concepts of COINS are explained
  • Core Model; The Coins 2.0 Core Model section specifies the classes and relations defined in this standard.
  • Semantics; The page Semantics give some initial concepts and explaination about semantics, triples, OWL, RDF and ontologies. For more detailed information there will be links available to external resources.

Core model classes and properties

The Core model classes and properties are defined here: COINS 2.0.
