3 Quality Requirements

3.1 Design Standards

All design work performed by the Contractors Designer shall conform to standards stated.

In the event of any ambiguity, inconsistency or discrepancy with the requirements of any referencedocumentation the designer must detail the ambiguity, inconsistency or discrepancy found, assessthe impact and advise RailCorp.

3.2 Selection and Use of Australian and International Standards

The Contractors Designer shall be responsible for the selection and use of the appropriateAustralian and/or International standards for individual design tasks, including:

The requirements of Lawson Concept Design Packages provided by RailCorp, and Requirements for compliance with NSW State and Federal Legislation and Regulations,

including NSW Occupational Health and Safety Regulations 2001, Environmental Legislationand Regulations, Electricity Legislation and Regulations, and

Additional requirements included in RailCorp Standards that limit or otherwise amplify theuse of other standards for RailCorp applications.

3.3 RailCorp Standards

RailCorp has adopted a series of internal Standards for use within the design of rail infrastructure.These include Standards prepared by, or on behalf of, predecessor organisations (RSA, RAC, andSRA) that have had responsibility for design and maintenance of the NSW rail systeminfrastructure.

The set of RailCorp Standards applicable to design tasks comprises two general types ofdocuments, as follows:

1. Standard Specifications. These generally cover physical and functional performancerequirements and limitations for items and materials used in infrastructure design andmaintenance. Standard specifications also include details of items or products that have beentype approved for use within the RailCorp system as well as limitations on the use of typeapproved products.

2. Standard Designs. These generally cover type approved designs that have been developedfor use in appropriate applications within the RailCorp Infrastructure.

The RailCorp Standard Documents referenced above may be used by the Contractor however theresponsibility for provision of a design which is fit for purpose remains with the Contractor.



28/49


3.4 Standard of Completed Design

3.4.1 Design Verif ication

Design verification ensures that the output from an individual design stage meets or is likely tomeet the verified inputs to that stage. Design verification is part of the process whereby designoutputs are progressively reviewed before the design is released for construction. The designershall note that any review undertaken by RailCorp will not transfer design ownership to RailCorp.

The design and any or all responsibilities incumbent with such design will remain with thedesigner. Verification of design output shall be achieved as specified below:

3.4.1.1 Design Verifier

The Contractor shall nominate their design verifier prior to acceptance of the design process andshall ensure that their nominated design verifier maintains compliance with the following

requirements throughout the duration of the design:

Holds the necessary qualifications to check design work for the discipline concerned, and hasbeen duly accredited by RailCorp. For external Contractors, design authority is delegated bythe General Manager Engineering to the person(s) nominated by the Contractor.

Has not been directly responsible for producing the design. Design checks shall be performedby the design engineer supervising the design tasks performed by members of that team butcan be performed by any competent and properly authorised engineer meeting the foregoingcriteria.

Upon completion of the Final Detailed Design documentation the Contractors design verifier shall

complete, sign and date a Design Verification and Approval Checklist to sign off their verificationof the final design.

3.4.1.2 Design Verification

The Contractors design verifier shall carry out the verification of the design documentationaccording to the RailCorp Engineering Design Management Procedure ED 0011 P prior tosubmitting for review. Verification shall proceed progressively throughout the design process.Progress of the verification shall be reported at the Technical Review meetings by presentation of aDesign Verification and Approval Checklist signed by the Contractors design verifier for the stageof the design covered by the meeting.



29/49


3.4.1.3 Design Validation

The Contractors design verifier shall carry out the validation of the design documentation on

behalf of the Contractor according to the RailCorp Engineering Design Management Procedure ED0012 P, prior to submitting for review.

3.4.2 Technical Reviews

3.4.2.1 Project Init iation Review

A Project Initiation Review (PIR) will be carried out as early as possible after the award of thecontract. The main purpose is to ensure that the design brief fully defines the requirements for thetask and that any inconsistencies or omissions are identified and resolved.

The PIR should take place after the design brief has been reviewed in detail by all applicablediscipline groups and following initial requirements analysis and allocation.

Submission of a Design Management Plan is required at the PDR including provisions for interfacemanagement.

RailCorps Authorised Person will convene the PIR.

Project Initiation Reviews shall be attended by representatives of the Contractors design staff, theRailCorp Delivery Manager, Stakeholders and representatives from RailCorp Design Section(s)appropriate to the scope of the task. The Delivery Manager will be responsible for chairing all

such reviews, in conjunction with the Head of the applicable design section(s).

3.4.2.2 Preliminary Design Review Meeting

The purpose of Preliminary Design Reviews (PDR) is to assess whether the proposed approach forthe design is consistent with the functional and performance requirements of the design brief.

PDRs will take place when the preliminary design has progressed to a level of detail that will allowthe intended approach to be assessed for compliance with the design intent of the design brief. ThePDR may be conducted in one session or in several sessions to consider individual parts of thedesign.

PDRs conducted with the designer will be attended by the RailCorp Design Delivery Manager,Stakeholders and the Section Head or a Team Leader from each discipline involved. RailCorp staffnominated to attend PDRs will have reviewed information delivered by the designer prior to themeeting.Minimum levels of information necessary to conduct an effective review include: Preliminary design and layouts drawings, including interface definitions, A summary of key assumptions made by the designer, Initial selection of major components and materials. The results of preliminary risk, hazard and human factors analysis, Preliminary reliability models and predictions available.



30/49


Design reports and calculations may be required in support of the review process but are notnormally delivered in advance of the review.

3.4.2.3 Detailed Design ReviewThe Detailed Design Review (DDR) will take place at or close to the completion of the detaileddesign phase. The primary purpose is to ensure that the design appears to be suitable in all respectsto proceed with construction and fabrication.

In this Contract construction is involved, the DDR will form a major input for determining whetherthe requirements of the design contract has been met.

In addition drawing reviews will be completed as detailed in Electrical Standard EP 00 00 00 15 SPCommon Requirements for Electrical Power Equipment Paragraph B3.3 Drawings. Drawingreview will be an iterative process until design is considered complete, following which all

documentation as detailed in Section2.4above shall be submitted by the to RailCorp.

The scope of the DDR is similar to the PDR, but addresses the proposed design in more detail. Thisincludes detailed drawings and supporting design information (design report and technicalspecification), safety and hazard analysis and final reliability models and predictions for the design.

The Design Delivery Manager is responsible for convening the DDR stage, by agreement with theContractors Design Manager, as applicable. Wherever possible the DDR shall be attended byRailCorp Stakeholders as well as RailCorp Section Heads or Team Leaders from each disciplineinvolved in the project.

3.4.2.4 System Verification Review

A System Verification Review shall be carried out to ensure all verification and validationrequirements of the contract have been met, including testing to the extent that it is appropriate tothe contract task.

3.4.2.5 Design Checking

Upon contract award design authority shall be deemed to be transferred to the Contractorsdesigner, being the appointed design consultant. Design checking will also be the soleresponsibility of the Contractors designer.

Design checking shall include the systematic review of design assumptions, calculations,methodology, use of standards and compliance with mandatory requirements as part of the designprocess by an engineer who:
