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.

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

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.

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
