EXECUTIVE SUMMARY

On January 26, 2022, City Council directed the Director of Rail Construction to undertake a third-party peer review of the Stage 2 Trillium Line Project to evaluate all aspects of the project, including design, construction, commissioning, training, operational readiness, and maintenance activities. The main objectives of this review are twofold: first, to analyze and validate the strategies and methodologies used by TransitNEXT, and second, to identify any potential issues or challenges that may arise at the start of revenue service.

Following a public procurement process, SYSTRA Canada Inc., in partnership with RATP Dev Canada, was selected to undertake a comprehensive review and analysis of the Stage 2 Trillium Line Project in May 2022. These two firms provide complementary strengths and a broad depth of experience to ensure that the Trillium Line peer review is thorough and reflective of the current state of industry practice worldwide.

SYSTRA Group is a world-leading engineering and consulting firm, while RATP Group is the world’s third largest public transport entity, provides operations and maintenance services on 30 light rail lines, and has active transit operations in 14 countries. Recently, these firms completed a similar peer review of the ARTM Blue Line Extension in Montreal.

The Stage 2 Trillium Line Peer Review Final Report highlights that both TransitNEXT and the City of Ottawa were receptive to discussion regarding the project's progress and challenges. According to the report, the process followed by TransitNEXT and their team is consistent with international standards and appropriate for delivering the Trillium Line project. The report also concluded that the project management practices are sufficient and that appropriate tools are in place to maintain control of the project's progress and to address potential risks.

The Peer Review Final Report made 47 recommendations. The City of Ottawa and TransitNEXT have formulated and implemented a comprehensive response and action plan to address all 47 recommendations, as detailed in this report.

The recommendations are categorized into five groups: Project Management, Rail Infrastructure, Rail Systems, Operations and Maintenance, and Safety.

To provide further context, it is important to note that the Stage 2 Trillium Line Peer Review was conducted while the project was ongoing. As a result, several identified issues were addressed progressively by the City of Ottawa and TransitNEXT. Any

remaining issues have either been addressed or have a plan in place to be addressed. The comprehensive response and action plan implemented by the City of Ottawa and TransitNEXT demonstrate their commitment to ensuring that the Trillium Line project is delivered successfully and meets the highest standards of safety and quality.

Project Management:

The peer review identified three recommendations related to the management of the Stage 2 Trillium Line Project. The City of Ottawa and TransitNEXT have implemented all three recommendations.

Rail Infrastructure:

The peer review identified five recommendations related to rail infrastructure, including additional design verification, design documentation, work methods, and standard operating procedures. The City of Ottawa and TransitNEXT have addressed three of the five items and have plans in place to address the remaining two.

Rail Systems:

The peer review outlined 20 recommendations related to the rail system being delivered as follows:

Six recommendations specify additional testing for the rolling stock. All tests have either been completed or are planned to be completed prior to substantial completion of the Trillium Line system.

Six recommendations for additional testing. This is to ensure a comprehensive testing and commissioning (T&C) program are developed and executed. As the project has progressed, the City of Ottawa and TransitNEXT have developed the T&C program to address all recommendations.

Finally, there are eight recommendations related to specific detailed technical requirements and specifications. The City and TransitNEXT have addressed each of the recommendations in accordance with the applicable standard, Project Agreement or industry best practice and as verified by the City’s third-party engineering consultants.

Operations and Maintenance:

The peer review identified nine recommendations related to operations and maintenance of the system. The recommendations deal with various operating parameters and requirements, additional operational scenario testing, and specific

maintenance related obligations. The City and TransitNEXT have addressed or have a plan to address the technical recommendations with at least two recommendations residing with the City for future decisions.

Safety Processes:

The peer review outlined 10 recommendations to improve the safety review processes and safety documentation for the project. These recommendations have been addressed through updated documentation, and where a different approach has been taken, the City’s approach to the application of the standards have been reviewed and validated by the City’s Independent Safety Auditor. For clarity, the City’s Independent Safety Auditor is SENER.

Conclusion:

The Stage 2 Trillium Line Project has undergone a comprehensive peer review process, which has identified specific issues and recommendations for improvement in various areas. All recommendations have been addressed by the City of Ottawa and TransitNEXT. The strategies and methodologies to address the recommendations employed by TransitNEXT have satisfied the City of Ottawa and in many cases have been validated by the City’s third-party engineering consultants and Independent Safety Auditor.

Overall, the City of Ottawa and TransitNEXT are committed to delivering a safe, reliable, and efficient rail system that meets the needs of our customers, community and stakeholders. We will continue to work closely with our partners and stakeholders to ensure that the Stage 2 Trillium Line Project is a success.
