Summary of change
Created document CAD Layer Standards for Service Identification Underground. Split standard into Above Ground and Underground
so that discussion on Above Ground doesn’t hold up signoff of
Underground.
Section 3: removed blocks from layer 0
Section 3: added layer 199 for service mixes that don’t match
defined layers
Section 5: created to explain handling of blocks
202 & 203 route type changed to ‘EXT’
220 & 221 route type changed to ‘unknown’
79, 80 and 85 route type specified ‘unknown’
81 & 82 included in table
Fixed Spelling mistake: culvert
Updated symbol used to be more consistent
New defs: DC, DRE, ARL
Added layers 105-110 & 233-235
Added definition: greyed cells = layers not imported
Greyed out layers 105-6, 233-5
Updated unknown DEPTH value to –99 (was –999)
Added layers 197 and 198
Entered into CDM Quality System
As per below table

Summary of change
Application of TMA 400 format and name change (formerly EP 0497)
Reword introduction and add related documents
Amend definitions for EXT, S&C, DC, PIT
Add definitions for EB, CCTV, SD, RTA, CAB, E, F, U, R
Change description of codes 77, 78, 81, 82
Add new codes 111-134 inclusive
Re-name heading, reformat table, and add layers 236-246 inclusive

Introduction
This document provides standard codes and equivalent CAD layer numbers which will
represent services and their installation type. It will be used as the basis for classification
of services and their construction method in CAD file format. The data will be collected
via field survey for the Detailed Site Survey (DSS) project and imported into RailCorp’s
Geographic Information System (GIS).
The number of code / layer definitions is likely to increase over time with the introduction
new asset types and combinations thereof. Amendments to this document must go
through the appropriate change management process to ensure that the relevant
stakeholders of RailCorp’s Engineering Services are informed. Applications in the GIS
are built from these standards and will require re-configuration when updated or
appended.

Blocks
Blocks will be placed on the layer of their parent route; therefore each route layer will
contain two feature geometry types:
• Line features: representing service routes.
• Point features: representing depth survey points.
Blocks will be attached to the point features and contain two attributes:
• DEPTH: depth (metres) from ground level down to the top of the service. Services
of unknown depth will be given a reduced level of -99.
• CLASS:
Class A: depth measured directly to top of service.
Class B: depth measured electronically.
Class C: depth unknown.
6
Redundant services
Redundant services are identified by the suffix ‘R’ after the route number but must still be
placed on the layer of origin. For example a redundant signals cable – 4R – must be
placed on layer 4.
If the origin of a redundant route is unknown it is simply called an abandoned route – 85 –
and placed on layer 85.
7
Un-located / Un-surveyed services
Services that are known to be in an area but cannot be accurately located or surveyed
are given a ‘U’ suffix and must be placed on their respective layer. For example an unlocatable optic fibre cable –16U – must be placed on layer 16.
The ‘U’ signifies that the position of that particular service is approximate only and must
be verified by pot-holing prior to carrying out any design or excavation works.
