Checking COBie using the COBie-UK-2012 application (1) COBie is naturally familiar and so no new nor informal structure is needed. . (2) Existing templates and examples can be rapidly re-used. Best practice can be automatically cut-and-pasted from existing COBie models. (3) Descriptions, enumerated allowed values and complex types (lists, tables, ranges) are available. Assignment to property sets can be documented. (4) COBie authors can cut-and pastee from the Matrix. (5) Checking applications can consume both the receivedd COBie andd the Matrix systematically. (6) Classification references can be included. Note that the methodology is independent of any specific choice of classification, ass long as the chosen table t is used in both the Demand matrixx and the COBie model. (7) Both COBie Object sheets (facility, system, component, type, floor, zone, space etc) and COBie Supplementary sheets (attribute, document, impact etc) can have the demands documented. Examples of the COBie Object and Supplementary sheets with expectedd gate of delivery appear below. 3.3 Stages The matrix will document the expected delivery gate: specifically it will identify the stage at the end of which the gate occurs. This is preferable to identifying drop numbers which may be redefined by the client. The current drop names can be correlated againstt with the CICC stage gate names.

It can be further amplified to document information requirements within the design and construction Supply chains. The stage at which each specific the information is first captured or documented may be earlierr than the stage at which it is expected by the Client. Some dataa may be expected by agreed processes internal to thee Supply side even if not demanded by the Client. Within a specific project, responsibility for authoring can be documented ed using the ‘Created By’ column, inserting entries from the Contact tab. Similarly the stage gate at which objects should be supplied can be documented in the ‘Created‘ On’ column. © 2013 AEC3 UK Ltd 12 February 2013
Checking COBie using the COBie-UK-2012 application Any such internal Supply side information is not checked by the rule-set. Completeness Note that if the Supply side does develop the matrix further, it must fit t within, and not conflict with, the Demand Matrix as referenced from the EIR. For example, the Supply chain should not plan to firstt supply data at a stage later than when it is being demanded. 3.5 Spatial and Physical Aspects of the Demand Matrixx Both COBie models and the Demand matrix cover two distinct information aspects: about the spatial objects (Floors, Spaces and Zones) and about the physical objects (Components, Systems and Types). The variety of physical objects o means that the demands will be for more extensive compared to those about the spatial objects 3.6 Demand Matrix Each demand matrix needs to t specify two distinct aspects: demands d onn the fixed objects sheets, and the demand on the t supporting attribute sheets. 3.6.1 Object Demand Matrix The expected stage that the fixed columns on the COBie object sheets can be documented. Some Sheets will need several rows to cover all the potential object specialisations and predefined types. Where there are several specialisations, such as types of Space, the category attribute is used to create a correspondence between the Demand Matrix and the Model. Figure 6: Example of a COBie Demand Matrix for Spaces (correction: created by, created on and category should not be tagged with a CIC stage; The Category attribute mightt read D: Spaces). In this example, Spaces should be created during the briefing stage, but the net area is not expected until after design development. The room tag may not bee determined until handover. The following object sheets are includedd in the Completenesss check: (a) Contact (b) Facility (c) System, Type, Component (d) Zone, Floor, Space Entries in the object sheets in the Demand Matrix are relatedd to entriess in the object sheets in the current COBie model by their category (classification) codes. Component entries are related through the classification of their Types. Exceptionally, the single Facility entry is directly related, without use off any category connection. © 2013 AEC3 UK Ltd 13 February 2013
