4 Hierarchical Levels

4.1 EAR – Level 1 and Level 2

The EAR is categorised into different hierarchical levels. The first two levels (Level 1 and Level 2) are

common across all Facility Types and are defined in the remainder of this sub-section.

4.1.1 Level 1 – Functional System

Level 1 (Functional System) is defined as a group of assets having a similar nature and function in ACTEW’s

Water Business. Each Functional System has an alpha code and a description. The codes and associated

descriptions are:

o SNET – Sewer Network

o WNET – Water Network

o RNET – Reclaimed Water Network

4.1.2 Level 2 – Facility Type

Level 2 (Facility Type) is defined as a group of assets having similar characteristics for service delivery within

the Level 1 classifications. Each Facility Type has an alpha code and a description. The codes and

associated descriptions are detailed in 9.1 Facility Types and Classifications.

The remaining levels in the EAR (Level 3 down) are dependent on whether the Facility Type is classified as

a Simple Facility or Complex Facility.

Simple Facilities are facility types that comprise a relatively small number of children assets and / or children

assets that are within a confined geographical area. Complex Facilities are facility types that comprise a

relatively large number of children assets and / or children assets that are not within a confined geographical

area. Simple Facility Types and Complex Facilities are detailed in 9.3 Simple Facility Types and 9.2

Complex Facility Types and Facilities.

The hierarchical structure of Complex and Simple Facilities are defined in Section 4.2 EAR Complex

Facilities and Section 4.3 EAR Simple Facilities respectively.

4.2 EAR Complex Facilities

Complex Facilities consist of a further 6 levels below Level 2 (Facility Type) as defined below:

o Level 4 (Facility Main Process)

o Level 5 (Facility Sub-Process)

o Level 6 (Equipment Location, Instrument Loop or Valve Location - Manual)

o Level 7 (Unit Location or Instrument Location)

o Level 8 (Unit or Instrument)






These levels of the EAR for Complex Facilities (including associated asset coding and naming conventions)

are further defined in the remainder of this sub-section except for Level 8 (Unit or Instrument) which is

described in 4.4 Units and Instruments.

4.2.1 Level 3 – Facility (Complex Facilities)

Facility has an alpha code and an associated description. Complex Facilities are detailed in 9.2 Complex

Facility Types and Facilities.

4.2.2 Level 4 – Facility Main Process (Complex Facilities)

Each Level 3 (Facility) is divided into one or more Level 4 (Facility Main Processes). A Facility Main Process

delivers a discrete process output within a specific Facility. Each Facility Main Process has an alphanumeric

code and an associated description.

The format of the Facility Main Process code is:

AAABB

Where:

AAA is a 3 character Facility Code representing the Facility (as detailed in 9.2 Complex Facility Types and

Facilities).

BB is a 2 character code representing the Facility Main Process.

Location, however in special cases a Unit may be located under an Instrument Location or under both a Unit

Location and Instrument Location simultaneously (see Section 4.5 Hierarchical Relationships for Units and

Instruments for further details).

Each Unit has an alpha numeric code and an associated description.

If the Unit has been tagged in the field then the format of the code is:

ANXXXXXX

Where:

AN is the code representing the term “Asset Number”.

XXXXXX is a 6 digit sequential number which is unique when used with the “AN”

prefix.

If the Unit has not been tagged in the field (due to technical limitations) then the format of the code is:

NTXXXXXX

Where:

NT is the code representing the term “No Tag”.

XXXXXX is a 6 digit sequential number which is unique when used with the “NT” prefix.

The naming convention for the description of a Unit depends on whether the description of the associated

Unit Type contains a forward slash and whether it has an associated Sub-Type (refer to 9.5 Unit Location

Suffix for a list of available Unit Types).

If the associated Unit Type is not configured in the corporate asset management system with a Sub-Type

then the Unit description is:

Unit Type Description






If the associated Unit Type description contains a forward slash and the Unit Type is configured in the

corporate asset management system with a Sub-Type then the Unit description is:

Sub-Type Name

If the Unit Type description does not contain a forward slash and the Unit Type is configured in the corporate

asset management system with a Sub-Type then the Unit description is:

Unit Type Description (Sub-Type Name)

Refer to 9.6 Unit Sub-types for a list of available Sub-types.

Examples of Units (codes and descriptions) include:

AN001234 – Motor Control Centre

AN001156 – Collector - Screw

NT000298 – Pump - Integral Motor (Centrifugal)

A full listing of Units is detailed in the corporate asset management system.

4.4.2 Instruments (Complex and Simple Facilities)

Instruments exist at Level 8 for Complex Facilities and Level 6 at Simple Facilities. An Instrument is a

physical asset that measures and/or regulates physical quantity/process variables such as flow, temperature,

level, or pressure. In the vast majority of cases each Instrument is located under a single Instrument

Location, however in special cases an Instrument may be located under a single Unit Location or under

multiple Instrument Locations simultaneously (see Section 4.5 Hierarchical Relationships for Units and

Instruments for further details).

Each Instrument has an alpha numeric code and an associated description.

If the Instrument has been tagged in the field then the format of the code is:

ANXXXXXX

Where:

AN is the code representing the term “Asset Number”. Note: the majority of instruments in the

field still have an “LMI” number. All new tags applied to assets in the field will conform to the

“AN” coding convention.

XXXXXX is a 6 digit sequential number which is unique when used with the “AN”

prefix.






If the Instrument has not been tagged in the field (due to technical limitations) then the format of the code is:

NTXXXXXX

Where:

NT is the code representing the term “No Tag”.

XXXXXX is a 6 digit sequential number which is unique when used with the “NT” prefix.

The format of the Instrument description is:

A B (C)

Where:

A is the Variable that the instrument is monitoring / controlling (e.g. Flow, Temperature,

Pressure etc. Refer to 9.8 Instrument Variable for a list of available Variables)

B is the Instrument Type (e.g. Element, Transmitter etc. Refer to 9.9 Instrument Type for a list

of available Instrument Types).

C is the Instrument Sub-type (e.g. magnetic, float etc. Refer to 9.10 Instrument Sub-type for a

list of available Instrument Sub-types) where applicable.

Examples of Instruments (codes and descriptions) include:

AN006789 – Flow Element (Magnetic)

NT000072 – Limit Switch

A full listing of Instruments is detailed in the corporate asset management system.

4.5 Hierarchical Relationships for Units and Instruments

4.5.1 Common Scenarios

In the vast majority of cases, each:

Unit is located under a single Unit Location; and

Instrument is located under a single Instrument Location.

Exceptions to the common scenarios are detailed in the following sub-sections.

4.5.2 Instrument not Part of an Instrument Loop

An Instrument is not created as part of an Instrument Loop if it satisfies at least one of the following criteria:

It is part of a piece of equipment and only applicable to the equipment, and does not display

readings or set alarms off anywhere (e.g. pressure switch).

It will be run to failure or very infrequently maintained.






If an Instrument is not part of an Instrument Loop then it will be located under a Unit Location within an

Equipment Location.

4.5.3 Unit with Integral Instrument

In this case the physical asset is predominantly mechanical or electrical in nature but has some

instrumentation to assist in carrying out its function. Examples of Units with Integral Instruments include:

Sampler

Chlorinator

Suphunator

Valves (with integral position transmitters)

VSD (with integral speed controller)

Metering / Dosing Pumps

A Unit with integral instrument is located under a single Unit Location within an Equipment Location and a

single Instrument Location within an Instrument Loop (i.e. it has two parent assets).

4.5.4 Unit that Supports an Instrument Loop

In this case the Unit serves no other purpose but to provide an Instrument Loop with a specific function. In

addition, the Unit would be disposed if the Instrument Loop were replaced.

A Unit that supports an Instrument Loop is located under an Instrument Location within an Instrument Loop.

5 Field Labelling Requirements

The following levels in the asset hierarchy require labelling in the field:

Equipment Location

Unit Location

Instrument Loop

Instrument Location

Unit / Instrument

Valve Location – Manual

Dam Structure Monitoring Location

Specifications for field labels are detailed in the remainder of this section.






5.1 Labelling Requirements – Equipment Locations / Dam Structure Monitoring

Locations

Every Equipment Location and Dam Structure Monitoring Location shall be labelled to ensure correct

identification. The label shall be of the engraved type and of materials suited to the particular environment it

is being installed into. The standard label material is Gravoply, however label material shall be approved for

use by the nominated Asset Owner. Labels shall be mounted such that they can easily be read from a

normal equipment viewing point, are not subject to damage and are obviously associated with equipment

item that the label refers to. Where an equipment item is likely to be removed for maintenance purposes

then the label shall be permanently fixed adjacent to the equipment item. Where equipment is unlikely to be

removed then the label may be fixed directly to the equipment item.

Equipment Location labels shall be in accordance with

Figure 1 - Equipment Location Label. The label size and character font size shall be appropriate to the size

and nature of the equipment the label refers to, readability taking into account the normal viewing position

and the label text format. Minimum requirements for the label text shall be 12mm high plain font for the

Equipment Location Code and 10mm high plain font for the Description and will be dependant on the size of

asset. For example, a text size of 20mm would be typical for an MCC and tanks could have a text size of up

to 150mm. Characters shall be upper case. The label shall be a minimum of 45 mm high and 150mm wide

and will be dependant on the size of the asset. Characters shall be black on a white background unless

otherwise specified.

5.2 Labelling Requirements – Unit Locations

Unit Locations shall be only labelled in instances where there is ambiguity and / or confusion in positively

identifying the Unit Location in the field (e.g. where there are two electric motors side by side). In instances

where Operations personnel require clear identification of the Unit Location’s function then the label shall

include a Description (as detailed in 4.2.5 Level 7 – Unit Location (Complex Facilities) or 4.3.3 Level 5 – Unit

Location (Simple Facilities)). The nominated Asset Owner will clearly specify which Unit Locations require

labelling and which labels require a description for each project. It is mandatory to label the following assets:

Variable Speed Drives

Soft Starters






Unit Location labels shall be of the engraved type and of materials suited to the particular environment it is

being installed into. The standard label material is Gravoply. Label material shall be approved for use by the

nominated Asset Owner. Labels shall be mounted such that they can easily be read from a normal

equipment viewing point, are not subject to damage and are obviously associated with Unit Location that the

label refers to. Where an equipment item is likely to be removed for maintenance purposes then the label

shall be permanently fixed adjacent to the item. Where an equipment item is unlikely to be removed then the

label may be fixed directly to the item.

Unit Location labels shall be in accordance with

Figure 2 - Unit Location Label. The label size and character font size shall be appropriate to the size and

nature of the equipment the label refers to, readability taking into account the normal viewing position and

the label text format. The minimum sized label text allowable shall be for a push button station or similar

device label where text shall be 5mm high. Characters shall be of plain font and upper case for both the Unit

Location and any required Description. Characters shall be black on a white background unless otherwise

specified.

5.3 Labelling Requirements – Instrument Loops

Every Instrument Loop shall be labelled at its primary device (usually the field transmitter unless otherwise

specified) to ensure correct identification. The label shall be of the engraved type and of materials suited to

the particular environment it is being installed into. The standard label material is Gravoply, however label

material shall be approved for use by the nominated Asset Owner. Labels shall be mounted such that they

can easily be read from the normal Instrument viewing point, are not subject to damage and are obviously

associated with the item that the label refers to. Where an item is likely to be removed for maintenance

purposes then the label shall be permanently fixed adjacent to the item. Where the item is unlikely to be

removed then the label may be fixed directly to the item. Where an instrument is mounted within a control

panel and this panel is associated mainly with this Loop, then the Loop label would normally be fitted to the

exterior of the panel.

Instrument Loop labels shall be in accordance with Figure 3 - Instrument Loop Label. The label size and

character font size shall be appropriate to the size and nature of the item the label refers to, readability taking






into account the normal viewing position and the label text format. Minimum requirements for the label text

shall be 10mm high plain font for the Instrument Loop and 6mm high plain font for the Description.

5.4 Labelling Requirements – Instrument Locations

Every Instrument Location, unless otherwise approved, shall be separately labelled with an Instrument

Location label to ensure correct identification. Typical locations where non installation of labels may be

approved are PLC I/O. Where the Instrument Loop label is affixed to, or adjacent a Loop Location device, an

Instrument Location label must also be affixed at this Location. The label shall be of the engraved type and

of materials suited to the particular environment it is being installed into. The standard label material is

Gravoply, however label material shall be approved for use by the nominated Asset Owner. Labels shall be

mounted such that they can easily be read from a normal Instrument viewing point, are not subject to

damage and are obviously associated with item that the label refers to. Where an item is likely to be

removed for maintenance purposes then the label shall be permanently fixed adjacent to the item. Where

the item is unlikely to be removed then the label may be fixed directly to the item.

Instrument Location labels shall be in accordance with Figure 4 - Instrument Location Label. The label and

character size shall be appropriate to the mounting location, amount of text and allow for ease of reading but

shall normally be 35mm wide and 20mm high with 6mm high plain font characters in upper case. Characters

shall be black on a white background unless otherwise specified.

5.6 Labelling Requirements – Piping Systems

Piping installations are to be marked in accordance with the Australian Standard AS1345.

5.7 Labelling Requirements – Units / Instruments

Every Unit and Instrument (where practicable) shall be separately labelled with an “AN” label to ensure

correct identification. The label shall be made of materials suited to the particular environment it is being

installed into. There are 3 standard types of “AN” label:

Aluminium (the default label type).

Gravoply (used in environments with high acid or alkaline concentrations).

Stainless Steel (used in aggressive environments that are generally submersible e.g. wet wells).

Aluminium labels shall be in accordance with Figure 6 - "AN" Label - Aluminium. Aluminium labels shall

normally be 19.5 x 30 x 0.3mm, black / blue print on silver MetalPRINT aluminium with an adhesive back and

11.5 point plain font characters.

Gravoply labels shall be in accordance with Figure 7 - "AN" Label - Gravoply. Gravoply labels shall normally

be 20 x 30mm, engraved black text on white background with an adhesive back, 14 point plain font

characters and a 5mm diameter hole in the top left hand corner.

Figure 7 - "AN" Label - Gravoply

Stainless Steel labels shall be in accordance with Figure 8 - "AN" Label - Stainless Steel. Stainless Steel

labels shall normally be 316 Grade Stainless Steel, 50 x 20 x 1.2mm, engraved with 18 point plain font

characters and two 5mm diameter holes (one on each end of the label).

Figure 8 - "AN" Label - Stainless Steel

Label material shall be approved for use by the nominated Asset Owner. Labels should be mounted, where

possible:

Directly on the asset.

Preferably not on components that can be removed or interchanged (e.g. not on the terminal box

cover or cooling fan cover of an electric motor).

If the tag can be applied directly to the asset then it should be installed on an area that is as flat as possible

to enable the entire underside of the tag to be in contact with the asset and facilitate a good bond. The area

should be thoroughly cleaned with a mild abrasive and Isopropyl Alcohol. If the tag can’t be applied directly

to the asset then the label should be secured with a stainless steel cable tie. There should be no loose or

sharp ends on the cable tie.

Unit and Instrument “AN” labels shall be installed by the nominated Asset Owner or the Asset Data

Coordinator following the installation of the component or device, or may be issued to the construction

contractor for installation.
