Clashes
A Clash occurs when portions of two elements occupy the same 3D space in a 3D model. The following terms are used to define a clash situation:
Clash number
A unique number automatically allocated to each clash
Element
Any named element in the 3D model that represents a physical item involved in a clash. An element cannot be a SITE or ZONE. Element 1 and Element 2 within a Group are specified.
Group
Multiple clashes between a pair of elements within a given volume may be grouped into a single Clash Group and may be selected for viewing, reporting or approval as a single entity
Discipline
The discipline responsible for resolving the clashes within a group. The discipline may be automatically or manually assigned.
Status
The following Status can be allocated to a Clash Group:
•
Unknown
- an initial or default status
•
Unapproved
- no action has been taken
•
Pending
- the clash is being investigated
•
Conditional
- the clash is approved subject to specified conditions
•
Approved

Comments
Descriptions of the current and/or historical situation regarding a group / clash detail
Clash Set
Defines the portion of the 3D model to be clash checked. This comprises the MDB name, and Obstruction and Check and Exclude lists. User defined Title and Comment can also be appended.
The Obstruction List contains the items that clashes are checked against. They are usually solid or large items such as walls, buildings and primary steel.
The Clash List contains the items that are to be checked for clashes with the Obstruction List items.
The Exclude List contains items to be excluded from the Obstruction List. An example of its use is as follows. If there are 30 Zones in a Site of which 28 are to be in the Obstruction List, rather than adding 28 Zones to the Obstruction List, it may be more convenient to add the Site to the Obstruction List and add the 2 unwanted Zones to the Exclude List.
