3 1 Purpose The purpose of this policy is to define the responsibilities and processes required for Metro Trains Melbourne (MTM) to fulfil its role as an Accredited Rail Transport Operator (ARTO) under the terms of the DMS Service Level Agreement, in order to comply with the requirements of the Public Transport Victoria (PTV) Drawing Management System (DMS) and the PTV Infrastructure Drafting Standards. This policy covers (and is written from the perspective of) Engineering Process & Interface Management (P&IM) Design & Review (D&R) policy for the control, management, reporting, project expediting and DMS interfacing on behalf of the MTM Engineering Division. This is to ensure KPIs for Engineering / Infrastructure drawings continue to be met and reported. 2 Scope This document applies to the management of Design Drawings, Issue for Construction (IFC) Drawings through to As-Built Drawings (ABD) by the Engineering, Process & Interface Management Design & Review team. However, for independent projects (e.g. Level Crossing Removal, Melbourne Metro Tunnel) at the discretion of MTM, the Director of Projects and Planning and the Director of Engineering - independent internal Projects - may establish/apply/manage/govern their own and/or contribute to engineering and infrastructure drawings management processes in addition to compliance and coordination with L1-CHE-POL-001. This policy does not apply to Rolling Stock managed by Fleet Engineering. It underpins alignment and compliance with the customer PTV DMS Policy. This policy shall be applicable to all works undertaken on the MTM network. It will be applicable for all works managed by MTM Projects and Planning Division (PPD), Infrastructure Delivery or external 3rd Party organisations, designs by design consultants and in-house designs undertaken by Engineering, and organisations that are responsible to complete as-built drawings. This policy serves as a generic document that applies to Engineering P&IM and all Engineering disciplines in common. Where applicable, PPD and Engineering (including Infrastructure Delivery) shall refer to all applicable (including discipline-specific) Standards, Processes, Procedures and Requirements. Section 8 stipulates the policy regarding design and IFC management while section 9 covers the policy on As-Built and As-In-Service management. 3 Governance Hierarchy Figure 1 below depicts the Governance Hierarchy amongst the various stakeholders associated with Design/IFC/As-Builts as described in this policy.

5 5 Definitions As Built (As In Service) Drawing Book In Book In Authoriser Booked Out Drawing Certifier Certified Copy Check Print Clean Copy Controlled Drawing Compliant Drawing Revised set of drawings submitted by a contractor upon completion of a project or a particular job. They reflect all changes made in the specifications and working drawings during the construction process, and show the exact dimensions, geometry, and location of all elements of the work as completed under the contract. A Drawing is considered As In Service when it accurately reflects the configuration of the As Built infrastructure in the field. The process of Booking In a Drawing after it has been Booked Out in accordance with the DMS Processes. The person (Head of Engineering (or delegate)) who determines that a Drawing Package has been reviewed and is ready to be authorised and booked in to DMS. A Drawing is considered to be Booked Out when it is locked and issued to a User for editing. A Drawing can only be Booked Out to one User at a time. Viewing of a PDF version of a Drawing is possible while the Drawing is Booked Out. The person who certifies that a Drawing is As In Service in accordance with the DMS Processes and who has the technical competency to perform this role to the reasonable satisfaction of the relevant Authoriser. A Certified Copy is a PDF version of the CAD Design for an As Built Drawing which has the signature of the Certifier that the AIS Drawing is the update of the IFC or Post-IFC Drawing capturing all subsequently approved Design Change Requests (DCRs) and accurately reflecting the latest Configuration of the network and as built condition. A Check Print is an As Built Drawing submittal believed to be a Compliant Drawing, but contains the Check Print watermark within the Title Block and does not contain the Certified Signature. Its purpose is to cut down administration within Engineering Review Time for Projects. A Clean Copy is an original PDF version of the CAD Design for an As Built Drawing which has not been signed by the Certifier. A Drawing is considered Controlled by a Drawing Controller when that Drawing Controller has Booked Out the Drawing in their name. Compliant Drawings are As in Service Drawings that have been certified and authorised in accordance with the DMS Processes and which comply with the components of PTV Infrastructure Drafting Standards & PASS Geometric Coordinates.

MTM As In Service Tracking Control Sheet (current template) and all applicable fields must be populated as per L4-CHE-FOR-035. All Projects fields in this form are to be completed; otherwise the design package may not be processed for review by Engineering. Non-Compliance: An Engineering As-Built Drawing Package will be rejected and returned to Project Completions if compliance with any of the listed protocols as detailed within this policy has not been met. 9.3 Management of As Built / AIS Drawing Package(s): All Engineering As-Built Packages must be submitted by individual discipline teams (Infrastructure Delivery only) or through Project Completions (applicable to Projects and Planning) via EDRG.DMS@metrotrains.com.au and hardcopy delivered to P&IM Design & Review team. NOTE: 1) Packages will not be accepted from individuals that are sent directly to individual engineers or without first going through Project Completions (applicable to Projects). 2) As Built drawings relating to M&R Retentions are to be submitted for review and DMS book in via M&R.Retentions@metrotrains.com.au with M&R Retentions tracker number for appropriate tracking and close-out with PTV. The Master As-Built DMS Register shall be managed and controlled by P&IM D&R team. This Register provides complete lifecycle management traceability from package receipt, review, DMS submittal and rejection/acceptance of packages from PTV. For Dispensation Requests, Test Copies and Overlapping Design Agreements, refer to PTV Infrastructure Drafting Standards and MTM Procedure L1-CHE-PRO-007 Management of Overlapping Design Agreement. For Unused Numbers, Unrevised Drawings, Non-Compliant Drawings, L4-CHE-FOR-043 [Unused, Obsolete, Unrevised Declaration Form] must be submitted. The applicable MTM Engineering discipline reviewer will review the As Built design, for its technical AIS compliance, PTV Infrastructure Drafting Standard compliance and provide comments on the Engineering As-Built Review Comment Template (L4-CHE-FOR-042). Engineering has 20 Business Days to provide the review of each As-Built Engineering Drawing Package (excluding submission and processing management, as well as the written response days themselves). Authorisation of PTV DMS Book in Forms shall only be carried out by a MTM Head of Engineering (or standing delegate) that has Drawing Authoriser status in PTV DMS. MTM/PTV Drawing Controller and Drawing Authoriser Master Access Listings are controlled by P&IM, as approved by the Design & Review Manager (P&IM) and PTV Manager, Configuration Management. If any errors relating to technical content/ PTV Infrastructure Drafting Standards/PASS Coordinates within the As-Built Engineering Drawing Packages are found (by the MTM Engineer or by PTV), the package will be rejected and returned to the project (via Project Completions) or delivery teams. They, in turn, will coordinate with the applicable designer(s) for rework and re-submission until compliance has been attained meeting all the above requirements.

12 A Compliant As-Built Engineering Drawing Package will achieve acceptance by the PTV s DMS through the DMS Book In Request Complete notification. This notification is provided to Engineering P&IM D&R Team by PTV for on forwarding by D&R to Delivery team or Project Completions to forward to the respective Project. Note: An initial notification is provided to D&R when an As-Built Engineering Drawing Package has been booked into PTV DMS. This does not indicate completion/compliance. PTV s CM Team via DMS conducts all compliance checks with PTV Infrastructure Drafting Standards/PASS Coordinates. Once a package has been submitted to PTV, MTM Engineering P&IM D&R has no responsibility or visualisation as to the workload/priorities/processing-time by PTV. If not accepted by PTV, the package will be rejected with an error report notification by PTV which will be forwarded to Project Completions by Engineering P&IM D&R for further action. Individual Non-Compliant Drawings within a Drawing Package when being re-submitted to PTV DMS will be done manually by Project Completions with Engineering being notified as Project Completions holds responsibility for individual drawing tracking/closeout. Overall responsibility for satisfactory As-Built completion lies with the MTM Project Completions Team. PRINTOUT MAY NOT BE UP-TO-DATE; REFER TO METRO INTRANET FOR THE LATEST VERSION Page 12 of 15

14 L1-CHE-POL-001 Version: 4 Effective from: 21 December 2016 Appendix 1 MTM Engineering Drawings Management Guideline for Best Practice Background/Scope: Engineering D&R team within Engineering P&IM - is the central point of contact for all IFC design and As-Built DMS Engineering Packages. They provide the key interface between Project > Project Completions > Engineering > PTV, facilitating Engineering drawing review & management between all engineering disciplines: Signals, Track & Structures, Electrical, OCS. NOTE: (Rolling Stock not applicable), across all MTM Project Works, M&R Works, Retentions, Legacy Project works. While also providing support across Alliance Projects and PTV initiatives. Purpose: This guideline is set to promote best practice recommendations for Engineering drawing management compliance and meeting Project milestones through Works Readiness gates and Project Completions process from the Engineering perspective. Guideline Recommendations: Issue For Construction (IFC) The Project team/alliance should provide Engineering (particularly for major projects) with a comprehensive Drawings Management Plan, Drawing Register (listing all booked out drawings/drawing numbers from PTV DMS) and Drawing Submission Schedule based on design lots and work packages. Design Packages are recommended to be planned early and split into manageable work submittals per construction stages and per discipline (e.g. for work occupations), as each design package would be reviewed and approved by Engineering separately to enable progress of each stage of construction. Detailed design packages should be submitted prior to T-12 for Engineering to review and comment within 10 business days. Every subsequent design package submission to Engineering should be accompanied with the designer responses to engineering comments and revised design drawing(s) or report(s) for close-out of comments raised by Engineering. Re-submittal without the designer response to comments will result in direct rejection of the design package. It is the project team s responsibility to ensure sufficient lead times for Engineering reviews and closing out of comments to achieve IFC at T-5 as per the Works Readiness requirement. As Built Management As Built packages should be broken down into design lots of work per discipline into manageable DMS drawing work submittals eg. 50 Drawings per package submittal (not exceeding 100 drawings in a package). Check-Print/Red Line mark ups should be provided at First Draft Review of As Builts. Certified copies will be accepted at 2nd Pass Engineering Review, 1st Pass submittal into PTV DMS. The project is to ensure that designers/contractors incorporate ALL comments identified by Engineering for submission of clean and certified As-Builts. Engineering Design & Review is available to provide PTV Infrastructure Drafting Standard checks, post Engineering (discipline) review.

15 L1-CHE-POL-001 Version: 4 Effective from: 21 December 2016 It is recommended the 1st Pass, draft As-Built packages are provided at T+0 for initial engineering review (T+20 days) for response to projects by T+4. Certified As-Builts should be provided post T+4 (T+20 days) for amendment review & initial PTV DMS submittal. This is mandatory to meet the T+8 milestone detailed in the Works Readiness. There are to be no outstanding comments remaining against an As-Built package prior to loading into PTV DMS. A possibility exists [upon agreements between the Project and Engineering] to attempt to meet towards T+10 day turnaround of As-Built reviews (for major programs) if dedicated resources were funded by the project and are available. NOTE: Total completion of an Engineering As-Built package (regardless of drawing numbers) can average between 2 to 3 passes, before final acceptance into PTV DMS. That can best case span between 2-6 months for completion. PRINTOUT MAY NOT BE UP-TO-DATE; REFER TO METRO INTRANET FOR THE LATEST VERSION Page 15 of 15
