Section Summary of change

DistributionThere are no restrictions on the distribution/circulation of this procedure/work instructionwithin John Holland Rail Pty Ltd Country Regional Network Project (JHR CRN).

1. Introduction

Much of the design work performed for the John Holland Rail Pty Ltd (JHR CRN) involvesthe application of established design principles, rules and standards to meet therequirements of a specification for new or altered infrastructure. Selection and use ofappropriate design standards is a key requirement in ensuring that the resultant designwill meet the requirements of the specification, comply with statutory regulations and be fit

for the intended purpose.Selection and application of the appropriate standard is an integral part of the designprocess. Similarly, any change to an approved standard represents a potential change tothe configuration of the infrastructure, may have a wide ranging impact on existinginstallations, and must be processed and approved through the ConfigurationManagement system, as described in Procedure ED 0014.

It is therefore essential that all design standards to be used by JHR CRN be carefullyselected, applied and controlled to ensure that infrastructure is designed, constructed ormaintained to achieve appropriate levels of safety and integrity. Conversely, the use of astandard that considerably exceeds the requirements of the application for which it is usedcan substantially increase the cost of both new works and ongoing maintenance.

2. Scope

This Procedure establishes general requirements for the preparation, selection and

application of design standards for use in all JHR CRN design tasks.

The Procedure does not include a list of Standards applicable to infrastructure designtasks. Information on specific Standards, including the current issue/revision status, mustbe obtained when the Standard is to be used for a specific design task.

3. Referenced Documents

NSW Rail Safety Act 2008 and Rail Safety (General) Regulations 2008

NSW Occupational Health and Safety Act 2000 & Regulations 2001

4. Definitions And Terms

Definitions used in this Procedure are in accordance with the Glossary included withProcedure ED 0001.

5. Requirements

5.1. Approved Standards

All design work performed by JHR CRN shall conform to approved standards.

Standards to be used for JHR CRN design work shall be: JHR CRN Standards

Australian Standards

Equivalent National or International Standards for railway infrastructure.

5.2. Selection and Use of Australian and International Standards

The Delivery Manager shall consult with the JHR CRN Principal Discipline Engineer whowill confirm the selection and use of the appropriate Australian and/or Internationalstandards for individual design tasks, taking account of:

The requirements of an Engineering Specification provided by the Client

Requirements for compliance with NSW State and Federal Legislation andRegulations, including NSW Occupational Health and Safety Act 2000 &Regulations 2001, Environmental Legislation and Regulations, Electricity Legislationand Regulations

Additional requirements included in JHR CRN Standards that limit or otherwiseamplify the use of other standards for JHR CRN applications.

Discipline Design Leads shall review and confirm that the Standards are appropriate tothe context of the design.






5.3. JHR CRN Standards

5.3.1. Types of JHR CRN Standards

The JHR CRN has developed a series of internal Standards for use within the design ofrail infrastructure.

The set of JHR CRN Standards applicable to design tasks comprises four general types ofdocuments, as follows:

Standards: These generally cover physical and functional performancerequirements, configuration, wear limits and failure conditions. They are developedas series for the various rail disciplines and cover design, maintenance &construction.

Manuals: These relate to the Standards but contain methodology for undertakingthe maintenance and construction tasks.

Specifications: Cover the physical and performance characteristics required ofmaterials, parts, of components of Rail Infrastructure.

Standards Designs/Drawings: These generally cover type approved designs thathave been developed for use in appropriate applications within the JHR CRNinfrastructure. Standard designs are typically documented in drawings (andspecifications) and define the configuration of items or installations that meet JHRCRN requirements for specific applications. Examples of standard designs includecertain types of bridges, turnouts. Standard designs may include standard repairsand serviceability criteria for the relevant installation.

JHR CRN Standards are primary configuration documents within the JHR CRN systemand the master copy is maintained in the Document Management System. Current Approved versions will be available through the JHR CRN Intranet & Extranet but areannotated as uncontrolled when printed. The designer shall regularly check for updatesand ensure that changes are tracked and managed in the design process.

5.3.2. Preparation and Revision of JHR CRN Standards

The preparation, revision and management of JHR CRN Standards are detailed in CRN – GM 002.

Issues with Standards or suggested improvements shall be directed to the PrincipalDiscipline Engineers for consideration.

5.3.3. Verification and Validation of JHR CRN Standards

Verification and Validation requirements defined in Procedures ED 0011 and ED 0012 shall be applied in every case for standard products and designs covered by JHR CRNStandards. This includes Type Approval of new products and designs before theStandard is approved for use.

Verification and Validation records shall be maintained as part of the design record insupport of the Standard. Design records shall be maintained within the responsibledesign Section.






5.3.4. Approval of JHR CRN Standards

JHR CRN Standards shall be subject to the approval process detailed in CRN GM-001:

5.3.5 Selection and Use of JHR CRN Standards

The existence of a JHR CRN standard does not mean that the item(s) covered by thestandard has been approved for universal application within the JHR CRN system.

Selection of items or designs that conform to either a JHR CRN Standard Specification ora Standard design for incorporation in an infrastructure installation is itself a designdecision. The decision must take account of the suitability of the standard item or designfor the intended application, including the specific usage parameters and environment for

the application.

Similarly, replacement of one type of Standard item with another, e.g. replacement oftimber sleepers with concrete, represents a change to the approved configuration.Changes of this type must be processed as a configuration change to existinginfrastructure, in accordance with the requirements of Procedure ED 0015.

Design engineers and supervisors have a general responsibility to ensure that JHR CRNStandard items and designs are selected for use in new and altered designs on the basisthat:

They represent an appropriate solution having regard to the safety, performance,reliability and environmental design requirements of the Engineering Specification

Except in cases where there is a defined requirement for standardisation, theyrepresent the most cost-effective solution for the requirement, and

They are the most current approved version.

6. Responsibilities

6.1. Delivery Managers

Delivery Managers are responsible for confirming the Standards applicable and managingthe Designers to ensure that the requirements are communicated and met.

6.2. Principal Discipline Engineers

JHR CRN Principal Discipline Engineers are responsible for advising the appropriatedesign standards to be used and for assessing and processing issues with Standards andimprovements to Standards in line with CRN GM-001.

6.3. Discipline Design Leads, Design Engineers and Supervisors

Discipline Design Leads, Design engineers and Supervisors of design tasks areresponsible for the review and use of design standards in accordance with therequirements of this Procedure.
