Implementing the BS1192:2007 Layer Standard

Whilst for many the perception of BIM was that there was no more need for Layers the reality is quite the opposite. The current British Standard for CAD Layering within the UK is BS1192:2007. Where specific BIM software does not support Layers then on export to CAD systems it must produce CAD data on the relevant BS1192:2007 layers.

This page provides some guidance on the implementation of the BS1192:2007 Layer standard, but for a more detailed description please refer to either BS1192:2007 itself or the supporting documentation produced by the BSI and links can by found on the British Standards pages on this site.

Wall Naming Convention

BS8541-1:2012 provides the standard for object naming conventions and this provides alternative methods of naming objects. It is assumed that Wall objects include classification metadata and therefore that approach 

A wall name needs to describe both its usage along with a list of its component width and its name .

The Fields associated with the wall naming convention are as follows:-

Field 1

Separator

Field 2

Separator

Field 3 (optional)

Usage

-

Width-Component

-

WallType

Components are always defined from the External to the Internal.

Each of the components will be associated with a material which consistently holds metadata in the form of property sets or parameters specific to that material. The material associated with a component may change through the design process, although the actual construction remains the same.

There may be occasions when on a project a wall has the same usage and components, but the materials associated to those components is different. In this case an optional wall type field may be used.

In order to reduce the length of AEC object names usage and components are abbreviated using common abbreviations defined.

Typical Wall Names

Generic Walls examples

Name = EXT-300GEN

Description = External, 300mm Generic

Name = INT-330Gen

Description = Internal 330mm Generic

Name = PRT-100GEN

Description = Partition 100mm Generic

Cavity Walls Examples

Name = EXT-103BWK_50AIR_50INS_100BLK_25PDB

Description = External, 103 Brickwork, 50mm Air Gap, 50mm Insulation, 100mm Block work and 25mm Plasterboard

Name = EXT-19RDR_100BLK_75INS_100BLK_13PLR

Description = External, 19mm Render, 100mm Blockwork, 75mm Insulation, 100mm Block work and 13mm Plaster

Floor Naming Convention

A Floor name needs to describe both its usage along with a list of its component width and its name.

The Fields associated with the wall naming convention are as follows:-

 Field 1

 Field 2

 Field 3 (optional)

Components are always defined from top to the bottom.

Each of the components will be associated with a material which consistently holds metadata in the form of property sets or parameters specific to that material. The material associated with a component may change through the design process, although the actual construction remains the same.

There may be occasions when on a project floor has the same usage and components, but the materials associated to those components is different. In this case an optional wall type field may be used.

In order to reduce the length of object names usage and components are abbreviated using common abbreviations defined.

Typical Floor Names

Generic Floor examples

Name = GRND-300GEN

Description = Ground Bearing Slab, 300mm Generic

Name = SUSP-330Gen

Description = Suspended 250mm Generic

Name = DECK-450GEN

British Standards

Various International and British Standards apply to the use of BIM and CAD within the AEC Industry within the UK. The BSI has published the following standards which should be considered.

AEC Object Naming Convention

In Computer terms most things are an object, therefore an object naming convention deals with all sorts of bizarre items not considered by most in the AEC Industry. The aim is to enable the transfer of information both person to person and aplication to application.

This AEC Object Naming convention is specifically aimed at the naming of AEC based objects found in BIM software such as Types in Revit families and / or Styles in AutoCAD Architecture / MEP etc...

For data to move from one system to another a common naming convention needs to be applied to all these objects along with agreed methodologies for BIM content.

BS8541-1:2012 provides the framework for naming objects and this includes objects with or without metadata. It is assumed  in this article that all AEC objects include metadata and that the classification does not need to be included within the object name.

Please refer to BS8541-1:2012 for further details.

The Name should be defined using the following three fields:

Source Type Subtype / Product
Author or manufacturer Discription of type of object Specific Type or product information to provide a unique identifier
Optional Required Optional

For a multiple component objects the naming convention should follow the following guidelines set out for the specific object or family types.

Ownership can by assigned as the first field in any object and is used to depict the author of the content in order to define ownership, risk and liability.
