    Default Vancouver Evergreen Line

    The Evergreen Skytrain line in Vancouver looks like it's about to start construction. It will be an extension of the existing Millennium Skytrain line to Coquitlam and Port Moody.

    Mayors want province, Ottawa to ante up for Evergreen transit line
    Concern mounting that project will begin without full funding in place


    Vancouver From Friday's Globe and Mail

    .Metro Vancouver's mayors are calling on the B.C. and federal governments to agree - before construction starts next year - to help TransLink pay its share of the cost of building and operating the Evergreen light-rail transit line.

    The group - the mayors' council that oversees the transit authority - gathered in a closed meeting yesterday morning. A late addition to the agenda was Premier Gordon Campbell's announcement on Monday that construction of the Evergreen line will begin next year, even with a $400-million funding gap unresolved.

    According to the mayors' council, the province announced that construction of the new rapid transit line through the northeastern part of the Lower Mainland will begin despite TransLink's failure to raise its $400-million share of the construction costs. Mayors are concerned about starting the $1.4-billion transit line before sustainable funding mechanisms are established.

    "The minute you stick a shovel in the ground and start to build it, you better have the capital dollars you need to build it," said Langley Mayor Peter Fassbender, who chairs the TransLink mayors' council. "Coupled with that, you also need the operating dollars to run the system after it's built."

    The federal and provincial governments and TransLink agreed to share the cost of the 11-kilometre transit line. TransLink, however, has been unable to come up with its $400-million share because its budget is already overstretched. Mr. Fassbender said TransLink is still determining how to cover the funding gap for construction, as well as long-term operating costs.

    "Carbon pricing policies and road pricing policies are options that we need to be looking at in the future," Mr. Fassbender said. "The mayors' council has not ruled anything out, but we just don't have a solution yet."

    Transportation Minister Shirley Bond said TransLink's inability to provide its share will not stop the province from moving on the project.

    "The mayors have certainly had their chance to move the Evergreen line forward and they have not been able to meet the commitment they made to bring dollars to the table," said Ms. Bond, speaking to reporters in Victoria yesterday. "We think the Evergreen line is important and so do the people who have been waiting for decades. We're going to get it done."

    However, it remains unclear where the province would get the money.

    Ms. Bond said she will meet Mr. Fassbender next week to discuss the project.

    "Our goal is to get the Evergreen line moving," Ms. Bond said.

    The mayors said they hope this will be a time to rally for increased government support to make up TransLink's share.

    "We hope to find a long-term solution for the operating costs that would look at all of the sources, whether they are municipal, federal or provincial," Mr. Fassbender said.

    "It has to be all of us looking at what we can do to find the sustainable solutions."

    Interesting that Vancouver is so committed to developing a regional ICTS system, while here in Toronto, where ICTS would be considered inadequate (as the SRT has demonstrated), we are stuck with the LRT-based Transit City plan.

    The Evergreen Line was originally Phase II of the Millennium Line (together with the Broadway West extension as far as Granville or Arbutus) - called the PMC Line (Port Moody - Coquitlam) at the time. It was cancelled by the Liberals when they cam into power in about 2001-ish due to budget concerns - the cost would have been about $700 million at the time.

    In the meantime, the Liberals eventually changed priorities to the Canada Line which was completed for the Olympics. The Canada Line only received approval at the regional government level if the Evergreen Line was built "concurrently" - it wasn't (due to funding issues).

    During that time, TransLink decided that the Evergreen Line was better as a cheaper LRT line instead of Bombardier technology (SkyTrain) (but still requiring a long tunnel through a mountain) - Vancouver was destined to get a forced transfer akin to the SRT problem (but SkyTrain-LRT versus Subway-SRT).

    In January 2008, the BC Liberals then made a unilateral decsion to revert back to SkyTrain technology for the Evergreen Line, which would provide a one-seat ride to Vancouver (as the originally conceived Millennium Line) and connect all of the major regional town centres with ALRT (ICTS). The cost of the line has risen to $1.4 billion. Each of Ottawa and Victoria have pledged about $400 million each. TransLink's $400 million share is the part that is unknown. A private partner is expected to provide the final $200 million.

    They've finally announced the awarding of the major contract - to the SNC Lavalin consortium noted in the previous post
    - now called EGRT Construction for
    a $889 million contract to design, build and finance the 11 km Evergreen Line (7 stations; 2 km tunnel, some at grade, some elevated).
    Someone posted on SSP that the tunnel will be a single large diameter bore instead of two parallel tunnels (no stations within the tunnel segment, which goes through a mountain).
    The line will open in Summer 2016.

    News Release:
    http://www.evergreenline.gov.bc.ca/d...006-000132.pdf

    EGRT Construction will build the elevated and at-grade guideways, a two-kilometre tunnel, seven stations, power substations, train operating systems and parking facilities, as well as a vehicle-storage and light maintenance facility.
    A $90.7 million contract with Bombardier was announced in December for 28 SkyTrain cars (confirmed to be MK-III (Innovia 300 series)). Note that rolling stock is being purchased separately since TransLink will be the operator:

    In addition to the announcement for Lincoln Station (posted above), there was a report (but no official press release (so far)) about accommodation for a future station at Cameron St. (halfway between Lougheed and Burquilam, on the map, above):

    According to a city planning report, the money will cover the cost of building taller columns to create a flat-enough section of guideway for the station, an additional set of track switches, and a contingency for possible environmental mitigation measures.

    By Friday morning, the Ministry of Transportation was on board.

    "The Province has offered to make provision for a future Cameron Station by modifying the Evergreen Line design. The Province is prepared to cover the costs exceeding $3 million including environmental mitigation and any overruns, if Burnaby pays the initial $3 million to modify the project to make provision for this future station," said a ministry spokesperson in an emailed statement to the NewsLeader.

    "This approach is consistent with that taken for other requested additional stations along the line, including the Lincoln Station in Coquitlam."

    Corrigan was pleased Friday afternoon when the NewsLeader gave him the news.

    "That's good, that's good news. And it shows a level of cooperation that hasn't occurred in every instance. So we're real pleased that we can work together to try to at least protect this as a long-term interest."

    I'm really impressed that Vancouver seems to be building an elevated alignment along North Road/Clarke. In Toronto I'm quite certain that we would claim that there isn't sufficient room for one through there.

    Plus it's a "stable neighbourhood", where I'm sure we would feel the need to tunnel. Clearly there are some different ideas in Greater Vancouver when it comes to rapid transit planning.

    Elevated was a given - it's down the middle of the road because it's the municipal boundary between Burnaby and Coquitlam and neither of them wanted the impacts on having it on their side of the street (although, as seen with the Canada Line in Richmond, a side of road allignment allows a lower elevation). A future station at Cameron will require a very tall guideway to accommodate a station mezzanine.

    Part of the "pre-construction" works was the widening of North Road by one lane to lessen the impact during the construction.

    Partnerships BC's Final Project Report:

    http://www.partnershipsbc.ca/files-4...2012-03-27.pdf

    1 Executive Summary

    ...

    SkyTrain technology was chosen for the Evergreen Line because it is estimated to have two and a half
    times more ridership than a Light Rail Transit (LRT) system; it will provide a direct connection without
    transfer onto the Millennium Line; and is almost twice as fast as LRT.

    The total Project budget is $1.431 billion, which includes the base project scope ($1.403 billion)
    and provision for Lincoln Station ($28 million). Funding for the Project includes contributions
    of $417 million from the Government of Canada, $400 million from TransLink and $586 million from
    the Province of British Columbia. In addition, the City of Coquitlam assembled a unique funding
    arrangement with a private partner and the federal crown corporation PPP Canada to enable the
    Lincoln Station to be constructed for opening day. The Province is responsible for the design
    and construction of the Project and, following completion, TransLink will operate the new line as
    part of the SkyTrain network.

    The Project will be completed in several parts. The Province has assembled the property required for
    the route and conducted various advance works to prepare the site for major construction. The
    Province and TransLink have together entered into a fixed-price contract with Bombardier for the
    supply of 28 new SkyTrain vehicles, and TransLink will supply fare collection equipment and faregates
    for the stations. The majority of the infrastructure – including guideway, tunnel, stations and systems –
    will be delivered by a single private partner.

    The procurement decision to use a Design Build Finance (DBF) partnership delivery model for the
    Evergreen Line infrastructure was based on a thorough analysis of procurement options. A Design
    Build Finance Operate Maintain (DBFO) model (similar to the model used for the Canada Line)
    was examined but deemed not appropriate for the Project because of the need for full operational
    integration with the existing SkyTrain system. A Design Build Finance Maintain (DBFM) model was
    rejected on the grounds that there would be greater economies of scale if the Evergreen Line was
    maintained as part of the larger SkyTrain system.

    A DBF model was chosen because it better met the procurement objectives, providing better risk
    transfer related to scope and schedule, as well as opportunities for innovation particularly through
    construction methodology.

    In December 2012, the Province entered into a performance-based, fixed price project agreement
    with the private partner (EGRT Construction) to design, build and finance the guideway, tunnel
    and stations; install the automatic train control and other systems; and test and commission
    the Evergreen Line. The term of the contract is approximately 3.5 years, and the fixed price of the
    contract is $889 million.

    During construction, EGRT Construction will receive partial progress payments to reflect a proportion of
    the work actually completed. EGRT Construction will fund the remaining portion and will be repaid
    when the Evergreen Line is declared substantially complete and meets a range of performance
    requirements. The project agreement includes a range of performance measures – for example
    traffic management and environmental protection requirements – which can result in a deduction to
    payments to EGRT Construction if those measures are not met.

    The Project is expected to achieve significant value for taxpayer dollars. In financial terms, the value
    for money is estimated at $134 million (net present cost) when compared to the Design Build (DB)
    comparator.

    The significant factors in achieving this value for money include:

    • The use of a single-bore tunnel, as opposed to the twin-bore tunnels envisaged in the reference
    concept. This approach is expected to result in a shorter time to bore the tunnel, significantly
    reducing schedule risk and potentially allowing the work to finish ahead of the required schedule;

    • EGRT Construction has accepted the risk of geotechnical conditions in the tunnel within its
    fixed price – the DB comparator assumed that the Province would share this risk and retain
    significant contingency to cover it; and

    • EGRT Construction has included efficient private financing including a mechanism that matches
    private finance to the month-by-month credit requirements of the Project.

    *****
    7.2 Key Terms of the Project Agreement

    Under the terms of the project agreement, EGRT Construction has an obligation to design, construct,
    test commission and partially finance the Project in accordance with the specifications set out in the
    agreement, and will receive payment for fulfilling these obligations. Key features of the project
    agreement include:

    • The design and construction of the Evergreen Line for a fixed price of $889 million excluding
    HST/GST and with the exception of costs associated with risks that are retained by the
    Province. The price includes the cost of PST following the re-introduction of PST in April 2013;

    • EGRT Construction accepted the risk of differing site conditions in the tunnel, which is a key
    project risk, within the fixed price;

    • The Province will make partial payments of $582 million during construction based upon actual
    progress. These payments will be insufficient to meet the full cost of constructing the line. EGRT
    Construction will raise sufficient debt to fund the remaining construction costs. This will be paid
    by the Province once the Project has been built and met specified performance requirements,
    with $307 million being paid at substantial completion.

    • At substantial completion, $40 million of this payment (or a letter of credit in this amount) will
    be retained for up to a year after construction is complete, pending proof that the Line will meet
    specified availability requirements under service conditions. In addition a further $8.9 million will
    be retained as security for the general warranty period;

    • As well as a general two-year work defect warranty, the project agreement includes
    additional specific component warranties (for example longer term warranties for station roofs)
    and a ten-year warranty for specific systems elements.

    • A payment mechanism that includes financial penalties to EGRT Construction if it fails to
    meet performance requirements in the project agreement, such as requirements to effectively
    manage traffic during construction or meet environmental requirements;

    • EGRT Construction must substantially complete the Project by July 29, 2016 or be subject to a
    financial penalty for every day of delay. Once the project has reached substantial
    completion, it will be transferred to TransLink. TransLink is required to put the new line into
    revenue service within one month of the transfer. TransLink will then operate and maintain the
    Evergreen Line as part of the overall SkyTrain system.

    Posted by nname at SSP - the redacted copy of the procurement contract has been released.

    Those of you interested in wayfinding will find Appendix H to be interesting - it is one of the only schedules not redacted and includes TransLink's Wayfinding Standards Manual.

    For the text part, I only have time to scan through some of them, but haven't found anything interesting yet. Seems like the section I'm most interested in (schedule 4, appendix A, B, J) are not released :yuck:

    Appendix H (dated 2012) are interesting though. Not sure how much the final product will change...

    The completed Lougheed station at concourse level:

    Note: Sign 21 and 51 says "Platform 3: Evergreen Line to Douglas College"

    Look at those advertisement panels (marked purple) at the platform!


    For Moody Centre, you have to go through two fare gates to get to the WCE platform??

    Note: From reading the document, those gates at the WCE entrance are supposed to be future gates. Only Compass readers is required for now.

    Last time, we prebuilt a platform at Lougheed station for the Evergreen Line. This time, the drawing shows that we will be building 2 stub tracks and 2 support columns for future Poco extension that might not happen before the end of this century... Seems like our provincial government is quite committed to build skytrain everywhere


    And this is what I gather from Appendix I - the potential track map for the line! This document is even older though (dated 2011) - it still have Cameron station, so I just put it in!

    Note: VSF = Vehicle Storage Facility... it is actually just lots of parallel tracks

    And my post - the train movements at Lougheed have been confirmed.
    Evergreen Line will through run from VCC-Carke to/from Douglas-LaFarge and the current Millennium Line will termnate at Lougheed.

    The double faregate / tap to WCE makes sense (it registers an entry to WCE) - otherwise the system wouldn't know if you travelled between, say, Moody Centre and Waterfront via SkyTrain or via WCE.

    VERY strange that the PoCo switch is west of Coquitlam Central - necessitating two stations (as shown on the track map). The preferred option should be like Bridgeport (centre platform) - otherwise, how would you know which station to go to to catch the next train to Vancouver? Plus transfers from Douglas to PoCo would be more difficult (looks like the PoCo to Douglas platforms are joined).

    The track map does not show the crossover east of Lougheed that would replace the "basketweave" that is required to get Coquitlam trains back to the righthand track - unless they run "wrong side" all the way to Burquitlam (but that would not make sense through a marked Cameron station).

    JACKPOT!
    This confirms the proposed train movements from SteelWheels' circa 1999 PMC Line brochure.
    And it does look like the trains will run "wrong side" all the way to Burquitlam (red and green arrows).
    You can also see that the Millennium Line terminates at Lougheed (blue and yellow arrows), with an easy cross platform transfer to Vancouver (but not from Vancouver).

    Evergreen Line project construction takes shape: first column in place


    COQUITLAM, BRITISH COLUMBIA – The Evergreen Line project is beginning to take shape, with the first guideway column for the upcoming Metro Vancouver rapid transit line in place.

    The elevated guideway column stands near the south tunnel portal at the corner of Como Lake Avenue and Clarke Road in Coquitlam.

    “The Government of Canada is proud to invest in infrastructure projects like the Evergreen Line that create jobs and economic growth, and improve public transit for Canadians,” said the Honourable Lisa Raitt, Minister of Transport. “This investment demonstrates the Government of Canada’s commitment to safe, secure, efficient, and environmentally responsible travel, and to building the infrastructure Canada needs for a strong future.”

    The 11-kilometre Evergreen Line will link neighbourhoods in Burnaby, Port Moody and Coquitlam and be fully integrated into the existing system, connecting directly onto the Millennium Line at Lougheed Town Centre Station. The project will create approximately 8,000 direct and indirect jobs during construction. The Evergreen Line is on schedule to open in summer 2016.

    “The Evergreen Line is an important rapid transit project in Metro Vancouver that will generate jobs, connect communities and provide more transportation options for families,” said Transportation and Infrastructure Minister Todd Stone. “Construction is moving ahead with columns being built to support the guideway in Coquitlam and residents will see work ramping up over the coming months.”

    Once it opens, the Evergreen Line will provide an efficient, easy to access, environmentally friendly and affordable transportation choice for families by linking communities and major centres. The Evergreen Line is expected to carry up to 70,000 passengers daily by 2021.

    “TransLink is excited to expand its infrastructure, growing Metro Vancouver’s transportation network,” said Ian Jarvis, TransLink’s Chief Executive Officer. “As we look ahead, we can clearly see that the demand for transportation is growing. The Evergreen Line will bring us closer towards a sustainable transportation network and help us continue to deliver efficient, effective and reliable service.”

    Guideway construction will continue in Coquitlam throughout the summer and fall, moving south on North Road to Lougheed Town Centre Station. In early 2014, elevated guideway construction will start in Coquitlam at Coquitlam Central Station and move north to Lafarge Lake-Douglas Station.

    In Port Moody, guideway construction will start this summer east of Barnet Highway and continue east towards Moody Centre Station. In the fall, guideway work will start at Inlet Centre Station. In addition, preparation work is underway for guideway construction along the existing railway corridor through Port Moody and Coquitlam. Crews are working to complete the necessary tree removal, build access roads, and install culverts and bridges to protect streams.

    EGRT Construction is building the elevated and at-grade guideways, a two-kilometre bored tunnel, seven stations, power substations, train operating systems and parking facilities, as well as a vehicle-storage and light maintenance facility. To build the elevated guideway, crews construct foundations and columns and an overhead guideway, followed by track work and systems installation.

    With major construction underway, Evergreen Line staff are continuing to meet with local residents, business owners and local governments, to keep them up to date on progress, and notify them of construction activities. Motorists can call the 24/7 traffic information line, or check the website for up to date information on active construction sites, and traffic closures or detours.

    Funding for the Evergreen Line is a partnership between the Government of Canada, the Government of B.C. and TransLink. The estimated project cost is $1.43 billion, with the Government of Canada contributing up to $424 million ($350 million from the Building Canada Fund, $67 million from the Public Transit Capital Trust Fund, and $7 million from the P3 Canada Fund), the Government of B.C. contributing $586 million, and other partners contributing $21 million. TransLink is contributing the remaining $400 million and will operate the system when it opens in 2016.

    Vancouver confirms Caterpillar as TBM supplier
    29 May 2013
    Peter Kenyon, TunnelTalk

    EGRT Construction, a consortium led by Canadian contractor SNC-Lavalin with Seli as its tunnelling partner, won the Can$889 million construction contract in January (2013). Since the purchase order was placed for the machine, Caterpillar made the shock announcement earlier this month (May) that it will not be taking new machine orders and will be withdrawing from the TBM manufacturing market by 2016 and closing its factory and workshops.

    "The manufacturer was chosen because they were the best suited to the needs of the Evergreen Line Project and Caterpillar was able to meet our financial and scheduling requirements," EGRT Communications Manager Jodi Rogers told TunnelTalk from Canada.

    "We have had detailed meetings with Caterpillar since the announcement that they are to cease their TBM manufacturing operations, and have received satisfactory assurances on the delivery dates. We are also comfortable that they will continue to support our machine through the construction period."

    "The purchase order was placed in January 2013 and delivery of the machine on site is scheduled for late 2013. Initial TBM boring is scheduled to begin in early 2014 and excavation will take approximately 12 months to complete," said Rogers.

    ...

    Caterpillar will supply a 9.84m diameter mixed face EPBM, plus back up, for excavation of the single-bore tunnel section. Specification calls for ability to withstand pressure up to 5 bar.

    The project has been in the making for more than a decade. The tunnel section was originally considered at concept planning stage as a twin-running structure requiring use of two EPBs, but EGRT was able to demonstrate significant savings at the bidding stage by suggesting a single bore alignment. Two risk options were offered at bid stage: one in which the geotechnical risks of tunnel construction were shared between contractor and the Client ([BC] Ministry of Transport and Infrastructure), and another where the contractor assumed all risk for differing site conditions.

    Under the terms of the three-and-a-half year fixed price DBF contract, EGRT assumes all tunnel-related geotechnical risk and agrees to penalty causes for delays to the summer 2016 project delivery date. During construction EGRT will receive partial progress payments to the value of Can$582 million from the Client, to reflect work completed, and agrees to finance through private instruments the Can$307 million that will be needed to complete the final phases of construction. Approximately Can$256 million of this will be reimbursed at "substantial completion" of the project, followed by a further Can$40 million after a year of satisfactory operation of the line. A further Can$9 million is withheld as security for general warranties.
