Preface The Asset Standards Authority (ASA) is an independent unit within Transport for NSW (TfNSW)

and is the network design and standards authority for defined NSW transport assets.

The ASA is responsible for developing engineering governance frameworks to support industry

delivery in the assurance of design, safety, integrity, construction, and commissioning of

transport assets for the whole asset life cycle. In order to achieve this, the ASA effectively

discharges obligations as the authority for various technical, process, and planning matters

across the asset life cycle.

The ASA collaborates with industry using stakeholder engagement activities to assist in

achieving its mission. These activities help align the ASA to broader government expectations of

making it clearer, simpler, and more attractive to do business within the NSW transport industry,

allowing the supply chain to deliver safe, efficient, and competent transport services.

The ASA develops, maintains, controls, and publishes a suite of standards and other

documentation for transport assets of TfNSW. Further, the ASA ensures that these standards

are performance based to create opportunities for innovation and improve access to a broader

competitive supply chain.

This document specifies the requirements for developing operations concept definitions for

transport projects.

This document is a first issue.

1. Introduction Development of operational concepts, as articulated in an operations concept definition (OCD)

is a key activity to be undertaken in the concept stage of the TfNSW system life cycle.

An OCD is required in order to understand how the new or altered system will be operated, and

therefore how much it will cost to operate over the expected system life time until retirement.

The OCD is a strategic guide and reference for maintaining focus on how the need or demand

will be achieved over the full life cycle, and not just an enabler for the business requirements.

2. Purpose The purpose of this standard is to provide a structured, repeatable approach to developing

OCDs on transport projects ranging from simple to complex new or altered systems.

2.1. Scope This document is a management standard for developing OCDs for TfNSW transport projects.

It defines key requirements for ensuring that all operational aspects of a transport project are

considered and fully defined, prior to the development of a supportable business case.

The scope of this standard is valid for TfNSW public and freight transport systems; initially

heavy rail, with planned future extension to other transport modes.

While this standard describes requirements for defining whole of life operation of new or altered

assets, it does not describe how life cycle costs are derived. For information on how life cycle

costs are derived, refer to T MU AM 01001 ST Life Cycle Costing.

This standard and the OCD in general shall be supported by a maintenance concept definition

(MCD), which addresses topics including maintenance support, spares and product type

approvals.

2.2. Application This standard is to be applied at the following operational levels:

• transport network level, for example all transport modes

• transport mode level, for example rail passenger and freight transport

• transport corridor level, for example North Shore Line, Southern Line

• local sites, for example transport interchanges, stations, yards, depots, control centres and

junctions

The initial objective is to develop and apply this standard to rail passenger and freight transport

projects, and then to extend application of this standard to other transport modes. This standard

is structured to ensure that its principles can be applied to other modes.

This standard is intended for application and compliance by entities responsible for planning,

investment and delivery of TfNSW transport systems, including the following entities:

• Transport Services (TSD), TfNSW

• Customer Experience (CED), TfNSW

• Planning and Programs (PPD), TfNSW

• Freight and Regional Development (FRD), TfNSW

• Transport Projects (TPD), TfNSW

• Transport Operators and Maintainers (OpCo)

• contracted AEOs providing support to TfNSW entities in preparing an OCD

This standard shall be applied in the plan (concept and specify) phase of the system life cycle,

prior to finalising the business case and the requesting of funding from NSW Treasury.

The OCD is a predecessor to preparing a business case and associated business requirements

specification (BRS). The OCD is a dynamic document that should be reviewed and if necessary

updated as the need is translated from a concept to a realised system.

The OCD is used to derive the business requirements in the BRS, which is further derived into

solution requirements in the system requirements specification (SRS). The OCD may be used

as the basis for validation throughout the system life cycle and as the point of r eference where

conflicts with the BRS and SRS cannot be resolved. Business and system requirements are

defined and addressed in TS 10505 AEO Guide to Requirements Definition and Analysis.

Topics described in this standard are to be tailored and scaled to suit the particular needs of

each transport project. In this context, a 'project' applies to a portfolio, program or project level.

• infrastructure delivery projects

• customers, including passenger and freight

• emergency services

• security control, monitoring and contract guard operators

• other transport owners and operators, for example Australian Rail Track Corporation

(ARTC)

The OCD shall relate responsibilities, ac countabilities and informing of operational users to the

operational process scenarios.

The OCD shall consider the implications on operational staff skills and any training or retraining

needed due to the operational changes resulting from the introduction of new or altered assets.

12. Operations migration The OCD shall describe how operations will be safely migrated from existing operations to the

future operations, including possible interim operations so far as is reasonably practical at this

stage of knowledge of the technology related to the new or altered assets.

The OCD shall describe arrangements to preserve acceptable levels of safety, timetabled

services, efficiency, asset integrity, and service availability during operations migration.

13. Operational interfaces The OCD shall identify and describe operational interfaces.

Operational interface attributes may include, but are not limited to the following:

• who or what organisations share the operational interface

• how information is communicated and coordinated across the operational interface

• what information is communicated across the interface

• categorisation of the operating interfaces as internal or external to the transport mode

Interfaces with internal or external organisations associated with assets across the interface

shall be identified.

The parties associated with the internal and external parties associated with all assets at/across

the interfaces should be identified.
