Safety in waiting

Monday, November 20th, 2017

Bus rapid transit (BRT) systems like viva use a variety of design features to make travel faster, but the primary feature is dedicated transit lanes that allow buses to bypass regular traffic. BRT systems around the world take different approaches as to where those lanes go. Some use separate lanes beside the roadway. Here in York Region, the vivaNext system uses median rapidways that run down the centre of the road.

median benefits

A major benefit of median rapidways is how they minimize conflicts with driveways and business access. However, this design requires passengers to wait for their buses in the middle of high-volume thoroughfares – such as Highway 7 West at the new Vaughan Metropolitan Centre rapidway station. Utmost consideration was given to design strategies that ensure the safety of passengers while they wait for their buses.

crash-load strength

The VMC Station’s most crucial safety protection are the white concrete barrier walls which run the length of the station on both sides, separating the waiting area from traffic lanes. With the wall’s white architectural concrete finish, curves that echo those on the station roof and tapering design that flows into the planters and ramps near the crosswalk, this wall is a key aesthetic feature of the new station. But don’t be fooled by its good looks: this wall is a brute.

It’s designed to withstand crash loads, the potential forces involved in a traffic collision. Crash-proof walls have to meet strict criteria on factors such as design, materials and construction. These specifications are set by Ontario Provincial Standards, and before we received approval to begin construction, every element of the design was scrutinized to ensure it met or exceeded those requirements.

standard scrutiny

Design standards dictate things like the height and thickness of the wall, how much rebar – steel reinforcements – is incorporated, how much it will weigh, and how the wall will be fixed to the base. Standards apply to the type of materials used for the concrete wall, the aggregate used to mix the concrete, the steel used in the rebar, even the coatings on the steel. Likewise, standards dictate the construction itself, ranging from how the concrete is cured to how edges are finished.

Although safety comes first, we made sure it looks good, too.

So now you know all the thought that went into protecting you while you wait for your yrt/viva bus, we hope you admire the design of the station, relax, and enjoy this impressive new addition to the Vaughan Metropolitan Centre.

be ready… 30 days to subway

Friday, November 17th, 2017

The countdown is on, and we can hardly wait! The first subway in York Region will arrive in just 30 days. The TTC Line 1 subway extension is a game-changer for transit in Vaughan Metropolitan Centre [VMC], York Region, and beyond.

Changes of this magnitude are fueled by the power of collaboration and funding partnerships. Today, vivaNext participated in a media event to kick off the countdown in earnest, along with the Government of Canada, the Province of Ontario, the City of Toronto and the TTC.

Read the news release

mega-connections at VMC

The TTC Line 1 extension isn’t the only connection coming your way. Everything’s changing, and that makes for better, faster transit service.

  • The Highway 7 West rapidway between Edgeley Boulevard and Jane Street, including Vaughan Metropolitan Centre Station in the centre of Highway 7, will open for service.
  • SmartCentres Place Bus Terminal will begin hosting YRT/Viva soon after.

Imagine, hopping on Line 1 at VMC Station and arriving downtown in just 45 minutes. Or from the subway, connecting directly to our Highway 7 West rapidway, or walking two minutes to the SmartCentres Place Bus Terminal, where YRT/Viva routes branch out across York Region. Soon you won’t have to imagine!

Today’s event was a warm-up for the big celebration on December 17, and you’re invited to share the celebration. Check vivanext.com/VMCopening for links to detailed information.

award-winning design

In other news, our rapidway in Vaughan is already getting noticed, for the quality of the design and also for the collaboration behind the scenes that makes it all come together.

Earlier this week, we were honoured to receive an Award of Merit from the Vaughan Urban Design Awards for the first phase of our Highway 7 West rapidway. The awards celebrate excellence in architecture, urban design, landscape architecture and environmental stewardship.

The rapidway, running from Jane Street to Bowes Road, was unanimously praised by the jury as “A great example of collaboration and investment between multiple levels of government to demonstrate significance on a city-wide scale.”

The jury also called the rapidway “a catalyst to knit communities together”, noting that the project “presents public transit as a ‘cool and hip’ mode of transportation” and “makes the everyday experience of transit a beautiful one.”

We hope you agree. Riding transit can be a beautiful experience.

a modern take on the ancient dome

Wednesday, November 15th, 2017

Here’s a question: what do some of the most impressive structures in the world, including many of the great cathedrals of Europe and the Pantheon in Rome, have in common with our new bus rapid transit station at the Vaughan Metropolitan Centre?

The answer: they’ve all followed the same basic construction technique for building a dome, which has been around for at least 2,000 years.

Domes have traditionally been reserved for a select number of important buildings which need to be impressively open and dramatic. Another reason there aren’t a lot of domes is because they’re more difficult to build compared to standard rectangular buildings. We loved the idea of creating an open and airy space for the Vaughan Metropolitan Centre rapidway station, making it big enough for viva buses to drive right through. We also wanted it to be special, and symbolic of Vaughan’s new downtown.

Although building materials may have evolved over the past 2,000 years, the general approach for building domes hasn’t really changed. First, strong, deep foundations are constructed to take on the full weight of the dome. Then, a temporary support structure is built. Gradually the permanent exterior shape is created up around the support structure until the dome is closed at the top. Once the dome is complete and able to support itself, the temporary support structure is removed, piece by piece.

Ancient domes would have had wooden temporary support structures, with the outer dome made of stones added one at a time. Although the materials we used are modern, we followed the same classical construction technique. First we built a steel temporary structure. Over that we installed the station’s outer dome, a steel frame welded together one segment at a time.

With the outer steel structure fully installed and all the structural welding complete, we carefully removed the temporary support structure one piece at a time, which took a couple of weeks. After this process was complete, construction inside the station began.

All the weight of the station is supported by the subway structure underneath the station, and 25 metre-deep piles or caissons which extend underground to the same level as the subway.

With its glass and steel shell exterior and high-tech comfort and amenities inside, we know you’re going to love using our new station for its modern look and functionality. But you can be proud of the fact that, from an architectural standpoint, it’s joining a pretty special group of buildings that have been built to stand the test of time.

rain, rain, go away

Monday, November 13th, 2017

Our new rapidway station at Vaughan Metropolitan Centre is ready for the rain, innately designed to handle a downpour and keep those pesky puddles off the road.

Large structures like the new bus rapid transit station shed a lot of rain during storms. With the size of the station’s roof, the volume of water collecting from even light rain storms would be enough to create some pretty major puddles.

Water management has been a key design consideration for the station since day 1. Letting runoff drain freely onto the roads isn’t an option since the station is right in the middle of Highway 7. Here’s the rundown on how we’re managing runoff.

Water management strategy includes features built into the station’s design, and the design of the road and storm water management systems around the station.

Gutters run along the curved station roof between the skylight and the roof panels, designed to collect and funnel water to the ends of the station. At that point, brow gutters – shaped like eye-brows – will drain the water into downspouts on the sides of the station, which then drain safely into underground catchbasins connected to the storm water management system.

But that’s not all! Water from the middle portion of the roof, below the roof gutters, will drain off the roof onto the road. Generally at our vivastations, the road design ensures water doesn’t become puddles.  A very gradual slope away from the station to the curb lane directs the water into a series of curbside storm sewers and catch basins.

However, the VMC station is so much larger than the other stations, there’s simply too much water to direct across the road. Instead, we drain the water closer to the station.

We’ve built up the road surface so that its highest point is 1.2 metres away from the station.  Water draining off the station will be naturally directed back towards the station, running along the curb into a series of catchbasins and into the storm sewers.

We know that rain gutters and catchbasins aren’t the most glamourous features of the new station, but on a rainy day, we’ll all be glad they’re there.

connecting people to people

connecting people to people

Have you ever wondered why the central markets, main streets and train stations of old cities thrive for so many years? Whether it’s the Temple Street Market in Hong Kong, the piazzas of Italy, or Toronto’s Union Station, it’s important to have a place to gather and connect. Somewhere to meet a friend or someone new, wait for the next bus or train, or just people-watch.

We all want to be around people, at least some of the time – Aristotle once said “man is by nature a social animal.” So in York Region, we’re hard at work building attractive places to spend our “connecting” time. A warm area at the station while you wait for Viva [it won’t be long!]… a place to buy coffee at the SmartCentres Place Bus Terminal in Vaughan, tree-lined sidewalks in Newmarket for walking along Davis Drive, or a trellis-covered plaza with benches to meet a friend at Cornell Terminal in Markham.

In this world of internet and mobile devices it’s easy to find ourselves isolated from the general population, so we’re using smart design to make sure everything we build connects people – not just vehicles.

 

matching the heights

matching the heights

With the extraordinary maneuvering required to install the roof sections of the VMC BRT station in its location in the centre of Highway 7, you might think the most challenging part of this project has been its incredible glass and steel canopy.

It’s true that installing the canopy of the station required a lot of planning and meticulous engineering. But actually, the coordination of the underground subway station with the BRT station above has been – and still is – a much more complex logistical challenge.

the mechanics of it all

Building the actual physical connections between the two structures was involved but not unduly complicated, similar to any building that has a framed structure on top of a concrete slab. Because the top of the station is wider than the lower part and overhangs at the edges, we couldn’t use rebar dowels, which are the most common construction method. Instead, we used mechanical couplings that enabled us to essentially bolt the top to the bottom.

working together

What makes the project more challenging is that the subway station is being built by the TTC, while the above ground BRT station is being built by vivaNext. With two different owners, and two different contractors, the project demands an intensive degree of coordination and planning.

Joint planning work began long ago, starting with establishing the specific requirements for how the project needed to be built, both below and above ground, and inside and outside the subway station. With the TTC building the subway station up to the surface, and vivaNext building the BRT station from the ground up, the heights of floors and ceilings had to line up perfectly.

top to bottom, inside and out

The vertical elements between the lower and upper floors – including the stairs, escalators and elevators – had to be installed early, with no margin for error. Escalators are very rigid, designed to fit perfectly between floors. And because the rapidway runs right through the station, the top of the escalator, stairs and elevator also had to align precisely with the existing level of Highway 7 outside.

At the same time as the TTC was building the lower levels of the subway station, we were outside building the civil works – the roadway, curbs and gutters – that surround the BRT station. Again, because the rapidway runs through the station, the heights of the underground parts of these elements had to fit with the height of the subway box below.

The BRT station is well on its way and is already a head-turner. In the not-too-distant future, all of this engineering and coordination will make it possible for you to step off the escalator at VMC subway station and easily make your way to the BRT station on Highway 7 and beyond.

making sparks fly

making sparks fly

If you’ve been near the future Vaughan Metropolitan Centre [VMC] vivastation recently, you’ve likely seen our welding crews up on man-lifts. And if you’re like most people, you probably didn’t give the welding process much thought – welding is welding, right? Lots of protective clothing, impressive clouds of sparks, and something gets permanently stuck to something else.

Of course, as always with all our engineering and construction activities, there’s so much more going on than meets the eye, and welding on the VMC station is no exception. Here’s the primer on what they’re doing up there, and what some of the complexities are.

Since we’re talking vivaNext, form and function both matter. There are two ways to join two pieces of metal: bolting them together, or welding them. Bolting works well enough, and is the most common method used on bridges, high rises and many other structures. But bolts show, and when the design – as for the VMC station – is for a smooth, seamless architectural look, bolts would be out of place. So welding was chosen as the method to join the pieces of steel throughout the structure.

Welding design takes into account the ultimate strength and performance needed from the structure being joined together, including the loads it will bear, and any flexibility it will require. In the case of the station’s steel superstructure, we are using “full penetration” welding. That means that the two elements being welded together are literally being fused into one piece. Rather than one piece being stuck onto the other, enough heat is applied that the two pieces melt and become one at a molecular level. With this type of welding, it’s not just one surface being glued to another; the joint literally goes through the full depth of the elements being connected. The resulting element is as strong structurally as one solid piece of material.

Once the weld is done, it is reviewed by the welding contractor for certification that the weld meets the required standards including having no impurities or voids. The reviews are generally done visually, although in some cases x-rays will be used. Our general contractor will also do their own quality control, and carry out random spot-checks on many of the welds.

In general, welding can be done until the temperature drops to -18 Celsius. But this specialized kind of welding requires warmer outside temperatures. When temperatures are -5 or below, some weld areas may need to be pre-heated with electrodes.

We’re moving as fast as we can to get the roughly 200 structural welds done, with welders working in shifts, each safely attached by full harnesses to a man-lift while they’re up high. Once the sparks are finished, and because it’s too cold out to paint steel, our last step will be to protect the welded areas with an anti-rust finish.

If you’re in the VMC area, we hope you’ll slow down and look around you. If you do, you’ll be able to admire up close its sleek, architectural lines, and understand all the work that went into making the steel superstructure smooth, strong and beautiful.

 

working day and night

Wednesday, November 16th, 2016

Those living and working in York Region know firsthand about dealing with construction. During prime construction season, you typically see worksites on a number of Regional roads. We need these road improvements to ensure our fast-growing communities are connected by a strong transportation system.

So how do we get these projects done when people still need to use the roads?

VivaNext rapid transit projects are carefully planned to manage construction and maintain traffic flow. There is a balance on every construction project between the need to get work done on schedule, the need to keep traffic moving, and the construction disruption to adjacent homes and businesses.

On occasion, night work is scheduled on busy roads such as Highway 7 or Yonge Street to avoid traffic congestion during the higher-traffic daytime hours. For example, on Yonge Street between Weldrick Road and 16th Avenue, there is up to eight times more traffic during the day than during the overnight hours.

We understand that sitting in traffic can make commutes longer. On the other hand, when work is done at night we know the noise and lights can make it difficult for those living nearby. The project still needs to be completed, so we move forward, trying to strike a balance – with over 99% of the four-year project being done during the day. Work is limited during peak traffic times, and crews work diligently to complete overnight work quickly so that it’s over as soon as possible.

We know that a good night’s sleep is important, and our crews try to minimize the amount of noise and light they create while they’re working overnight.

Day or night, it helps to know what’s coming so you can plan around it. You can sign up for email notices at vivanext.com/subscribe. Thank you for your patience and understanding.

the ballet of building the VMC canopy

Friday, October 21st, 2016

Vaughan Metropolitan Centre – Spadina Subway Station

The giant sections of structural steel canopy were installed this fall in the Vaughan Metropolitan Centre [VMC] area – right in the middle of Highway 7 West – and it was a ballet of precision.

Having a large structure like this arise in the centre of a roadway is an incredibly unique construction event.

That’s why we made sure we were out on the corridor watching and recording the action to share with all of you.

The largest section lifted was 25,000 lbs – over 11,300 kg! You can read more about this new Vivastation, and check out the video to see how this feat was done.
