We already exceed the TTC subway and Montreal metro for reliability. No train is going to work perfectly 100% of the time.

What the system needs is resiliency: being able to more quickly recover from small incidents.

True, but you also have to look at how preventable the breakdowns are. Older trains are going to be less reliable no mater how well maintained they are. When the issues are caused by poor design (computer bugs and flimsy doors) the issues need to be addressed and not just shoved under the rug with the excuse that all systems have reliability issues.

Agreed. For one, when a train does need to go out of service, there should be a procedure for having it run empty back to the garage without having to slow down the entire line.

That is not always possible.

This morning, there was a switch issue that shut down the C-Line between Blair and St. Laurent. There are still too many problems and they seem to most often arise during peak hours.

Again. It feels like that's the alert I receive most often. My guess is there's a problem switch there that isn't getting any better.

And speaking of alerts, there appears to be a problem sending to gmail accounts so I get them often hours after they were sent (but the time stamp is the current time.) Or I'll get an all-clear when I never got the R1 in service comment. Last night, it talked about a power outage at Blair so those with mobility issues were required to take a para Transpo bus around to their stop because there were no escalators or elevators (train was running fine.)

I checked on twitter and there was no tweet about that at all. Nor anything from Ottawa Hydro about an outage in the area. Which made me wonder if it was a test message that got sent by accident.

For now, I'm using OccasionalTransport, #OttawaLRT and the OCT tweets to know if things are running well. Communications are still not running well enough to be relied upon (nor is the 560 system which was down again for maintenance last week.)

The issue this morning seemed to resolve fairly quickly. I arrived at St. Laurent just as a bunch of R1s from the east did. The platform clogged, then quickly unclogged as a train came back into service westbound.

Pro tip, people: when this happens, you can always wait for the second train back in service. Sheesh.

RTG outscored competitors to win Stage 1 LRT contract, but evaluators noted downfalls
While the city released the Stage 2 O-Train procurement scores earlier this year, it has never released the Stage 1 procurement scores.

Jon Willing, Ottawa Citizen
Updated: December 5, 2019


The Rideau Transit Group received the best technical and financial scores in the Stage 1 LRT contract competition, but newly released records show bid evaluators recorded flaws in the proposal on several fronts, including on construction, design and communications.

The Stage 1 procurement scoring documents, obtained by this newspaper through access to information, show RTG beat the two other shortlisted bidders for the $2.1-billion construction contract and long-term maintenance deal, with evaluators in 2012 ranking RTG the top bidder based on the consortium’s final procurement score. RTG met the minimum technical scoring thresholds for the massive project and the strength of its financial bid secured a win.

While the city released the Stage 2 O-Train procurement scores earlier this year, it has never released the Stage 1 procurement scores.

The Stage 1 contract scoring offered comments on each of the 19 technical categories, and RTG largely received positive comments from evaluators. “Strong team,” “strong approach with the use of sophisticated tools,” “very good overall strategies” and “solid understanding” of risks were some of the comments recorded by evaluators.

However, the five-member evaluation team noted several negative attributes of all the bids, including RTG’s bid.

On RTG’s risk management plan, evaluators observed that the bid “did not adequately describe the tunnel risks” and “did not describe management responsibilities.” Evaluators saw a “weak” environmental management plan and a tracking system for environmental incidents that was “lacking detail.”

When it came to RTG’s approach on utilities, evaluators noticed a “lack of detail on drawings,” and on geotechnical information, they noticed RTG’s plan was “lacking detail on impacts to adjacent structures.”

The design evaluation prompted evaluators to observe no discussion by RTG on public art and an urban design proposal that had a “narrative focused almost solely on NCC approvals.” Evaluators didn’t find good descriptions of station integrations not subject to approvals by the National Capital Commission.

While evaluators agreed RTG demonstrated a “good understanding” of specifications on the LRT guideway, they noted a “weak description of design considerations for snow clearing and storage.”

A review of RTG’s tunnel design prompted evaluators to write, “addresses understanding of project requirements however, results of analysis and proposed solutions represent project risks.” Evaluators, for example, saw that RTG didn’t believe mitigation measures for adjacent structures were required for anticipated ground settlement.

RTG received a higher score on its communications plan compared to the other two bidders, but evaluators saw a “poor approach to government relations” and that RTG had “little demonstrated experience for government and media relations.”

The city on Thursday was unable to respond by deadline on how it made sure to mitigate the negatives in RTG’s bid after the consortium won the contract.

RTG’s main partners are SNC-Lavalin, ACS Infrastructure Canada Inc. and EllisDon.

The other two shortlisted bidders were Ottawa Transit Partners (Vinci, Acciona, Aecon, Bombardier) and Rideau Transit Partners (Bouygues Travaux Publics, Brookfield Financial, Fiera Axium Infrastructure, Parsons, Colas Rail, Johnson Controls).

The request for proposals required minimum technical, design, construction and maintenance scores of 70 per cent. The financial plan required a minimum score of 60 per cent.

The consensus technical scores for the bidders were close. RTG did best at 79.83 per cent, followed by Ottawa Transit Partners at 78.98 per cent and Rideau Transit Partners at 78.28 per cent.

RTG easily walked away with the top-ranked spot with its financial score of 98.5 per cent.

As it turns out, the Stage 1 procurement wasn’t like the controversial Stage 2 procurement of the Trillium Line expansion where the winning bidder, SNC-Lavalin, won the contract by having a below-threshold technical score but a strong financial score, which carried the company to victory.

For the Stage 1 procurement, all three bidders achieved at least 70 per cent on almost all of the 19 technical sub-categories. The one sub-70 score was Rideau Transit Partners’ 68 for safety management and certification and regulatory matters.

RTG’s technical sub-category scores ranged from 72 per cent on the low end for its utilities submission to 85 per cent in areas of risk management and safety management.

Today, the heat is on RTG when it comes to its maintenance of the LRT system — for which the consortium is receiving more than $2 billion over a 30-year term for Stage 1, a sum that increases substantially when Stage 2 LRT maintenance is included — even though the consortium easily met, and exceeded, the minimum 70-per-cent score during Stage 1 procurement.

RTG scored 80 per cent on its maintenance and rehabilitation plan, and the other shortlisted bidders scored 80 per cent (Rideau Transit Partners) and 86 per cent (Ottawa Transit Partners).

Evaluators noted that they didn’t see a preliminary asset management plan or handover plan in RTG’s bid, and they described RTG’s approach to ensuring compliance with regulatory inspections and testing as “marginal,” but their overall comment was that RTG’s strength was having maintenance staff involved from the beginning of testing and startup activities.

The city announced this week it’s hiring outside experts to make sure RTG is properly maintaining the rail system after more than two months of unreliable LRT service.

That station is cursed. Twice I have dropped my coffee mug in there.

I get the same issue on Gmail. I'm not sure if it's specific to Gmail or all e-mail in general, but many of the alerts are delayed by hours. The text alerts come through right away.

Hydro Ottawa did tweet about a power outage in Beacon Hill-Cyrville on Wednesday Dec 4... the 1st tweet was at 12:14 pm and it was announced as resolved at 1:06 pm. That's about the same time as OC was announcing a power outage at Blair.

The good thing this shows is that a localized power outage has no impact on train service.
