Designing for an optimal outcome

Transcription

1 PWI Technical Seminar : Modernising the Railway Network 25 th February 2016 Designing for an optimal outcome Sharing some of the lessons learnt from survey and track design development that can help to ensure the optimum outcome from an enhancement project.

2 SNC-Lavalin - A world leader Founded in 1911 Leading engineering and construction firm Major player in infrastructure ownership End-to-end solutions: Engineering Procurement Construction, Engineering Procurement Construction Management, financing, operations & maintenance services Operating in 4 key sectors Infrastructure Mining & Metallurgy Oil & Gas Power Rail & Transit Engineering 2

3 Full end to end service in Rail & Transit Complete systems delivered Canada Line, Vancouver, Canada Designed, built, financed & operated for 35 years a new automated metro from Vancouver airport to Vancouver city centre in JV with British Columbia Investment Management Corporation (BCIMC) and the Caisse de dépot et placement du Québec (CPDQ). Service commenced in Rail & Transit Engineering 3

4 Rail & Transit Engineering overview Global Rail & Transit business; with staff and offices worldwide Encompassing all types of railway systems Engineering design Engineering consultancy Major project management Transport Advisory Supporting the complete railway lifecycle Rail & Transit Engineering 4

5 We cover all Rail disciplines Rail & Transit Engineering 5

6 Project examples Light Rail Manchester Victoria tram interchange track alignment Mainline Frederick Road track lowering survey, track & drainage design Freight New connection into WCML for Acrow quarry; survey & design High Speed HS2 Technical Support: Concept / feasibility study to divert HS2 Metro Victoria, Aus; Grade separation feasibility designs Other Disciplines WCML Power Supply Upgrade Point cloud survey and OLE design 6

7 Rail asset life cycle 7

8 Asset and Project life cycle Railway infrastructure asset management across the whole asset life cycle (pre and post GRIP) Engineering support to project life cycle (GRIP1 to 8) 8

9 Concept/ Prefeasibility/ Output Definition: Outline scope and project outcomes to be defined. Information required to inform the process Asset Management and Operational input essential. Stakeholder workshop to get input and buy in SI and GI as early as possible. Minimise surprises during design development.. Use of Records drawings, info from adjacent sites, operational and asset management systems. Design risks assessment (DRA) + mitigations Define approvals and certification requirements Output an informed and agreed Project Requirement Specification 9

10 Concept/ Prefeasibility/ Output Definition: (cont): Use mapping and survey technology. Example of survey and design using OS mapping and Google Earth data. Example: Stoke branch alignment design to HS2 feasibility study.. Various alignment options evaluated Appropriate level of detail Planning + Engineering feasibility Use of technology 10

11 Feasibility and option selection: Option selection based on first cost and whole life cost assessments. Strong design project Management Competent design team Collaborative approach Shared and agreed goals Maintain Design Risk assessment No delays in TQs etc Get construction input to design option selection by early contractor engagement. Access Planning early on. Use technology. Fly through 11

12 Victoria grade separation feasibility designs 12

13 Single option development: Involve other engineering design disciplines (OLE, Signals, Comms etc) Keep all parties informed as design is developed, no surprises.. Tender estimate Develop efficiencies through design and construction methodologies Value add and cost savings Strong project and design management processes. Open and honest communication all parties. Collaborative approach. 13

14 Single option development Enhanced 3D digital survey data for example Lidar to create more detailed survey. Establish survey grid for design, construction and maintenance. Survey once and use many times Chris Preston 14

17 Detailed design: Compliant. Address risks. Flag non compliances as early as possible. Pragmatic engineering. Identify any residual risks/ asset management requirements. Design for safety. (key issue) Construction input for buildability. Interfaces. Timely AFC sign off and approval 17

18 Managing Risk: Safety in design 18

19 Managing Risk: Safety in design 19

20 Construction: Build in quality to optimise asset life and return on investment. Collaborative approach. Get designer involved in construction. Learning and knowledge transfer; a means of developing staff for the future. Post construction lessons learnt. Improvement in time, safety, quality, cost reduced risk. Process improvement... 20

21 Completion: Hand over to operations & maintenance Testing, Commissioning and approvals Involve designer and asset manager. Hand over and explain survey and design; particularly any on-going operational or maintenance requirements. Capture design data and produce records Review and amend asset management systems and plans Digital Railway BIM... Take learning into next projects. Continuous improvement 21
