Checking COBie using the COBie-UK-2012 application
0 Introduction
The BIM
task Group has already published an outline guide to t COBie-UK-2012 including
checklists for compliance. It is expectedd that subsequent submissions of COBie datasets
should show continuity whilst adding more detail. Recently the published templates has
been developed into the COBie-UK-2012 demand matrix. These publications allow
the
development of tools to check the quality of COBie
datasets.
Since the first steps of UK BIM implementation, the importance of levels of detail within
BIM adoption have
been recognised. The recurrent remark for the needd to identify
what
information was to
be exchanged and when, has led to the developmend
nt of a UK BIM
Element and Attribute Demand Matrix.
The UK BIM Element and Attributee Demand Matrix (COBie-UK-
standards for information
necessary to include in BIM models from
inceptionn through project p delivery establishing
what information
is exchanged at several project stages. This guidancee is presented as a
2012_DemandMatrix.xls based on COBie), starts to provide
COBie-like document to be used for identifying and tracking BIM information, it covers
Building
Information Types, (as well as Facility, Floors, Systems and Spaces), when they
are relevant, and to what level of development (in-line with CIC stages) throughout a
building
lifecycle. The Systems, Types and Spaces
elements are organized and ordered
by general Uniclass classification and properties listed as Attributes, marked with the CIC
stage by which they are expected.
To
prove the
concept the demandd matrix is being tested to show how the
information listed under spatial and physical objects could bee used to answer clients’
questions. Using a Classroom
as an example, 10 Types from the Objectt Matrix were
prioritised (FFE, Doors, Windows, Wall exterior, Wall interior, General Lighting, Audio
Visual, Telecommunications
and Data Network). The properties presumed to answer
clients question were selected and included on the
Classroom
BIM model at specific
project stages (released as IFC I and as COBie at four specific CIC stage-gates).
To
demonstrate automated checking, a single application (developed by AEC3)
generates three separate marked up versions of a COBie submittal thatt show:
Compliance with the COBie standard, checking data integrity
Continuity is judged by
detectingg the addition and removal of f objects and
attributes, along with changes.
Completeness is judged against a list of properties and a attributes along
with
the expected stage at the t end off which they should be provided.
