the crowning touch

Ready for the crowning touch? The new SmartCentres Place Bus Terminal comes with a mesmerizing pièce de résistance – a sweeping, curved wooden roof, as beautiful as it is functional.

Reminiscent of West Coast style, the horseshoe-shaped roof shelters the outdoor bus stations in beautiful elegance. A fluidity breathes life into the design, curving in a slight v-shape from the outside in, and rising up at the wingtips and the saddle. You can almost feel the motion, very fitting for a bus terminal with YRT/Viva services branching out across York Region.

an intricate jigsaw puzzle

The simple elegance of the roof belies the complexity of its creation. The wood pieces need to look curved, but they are flat. Custom-cut to the architect’s design, they fit together with the steel substructure, which was also designed in custom pieces.

It’s like a very complicated jigsaw puzzle. Every section is numbered and assembled with exact precision. When the flat pieces fit together, they create the appearance of a curved roof. High-strength glued-laminated timber beams support the roof, running vertically and also lengthwise.

Not only does the wood look stunning, it was a cost-effective choice and is Forest Stewardship Council (FSC) certified to York Region standards. When it’s finished, it will be stain-coated with intumescent fire-retardant material.

 a showstopper for a new downtown

The result is an eye-catching landmark – a roof that draws the eye and a terminal where you can pass the time in style. After all, SmartCentres Place Bus Terminal is not your run-of-the-mill bus station. As part of the vibrant, new downtown flourishing at Vaughan Metropolitan Centre, this bus station needs to look the part.

Set to open in 2018, the Terminal will complete the transit powerhouse at the VMC: subway, rapidway and YRT/Viva terminal, working together to move you, faster and easier than ever before.

the concrete choice

If you’ve ever renovated your home, you know about the endless options for flooring: tile, wood, carpet, stone. Once you select your material, you have to make more choices about colour, finish, how it should be arranged, even the kind and colour of grout. So many decisions! Of course, as with all design questions, your choices are shaped first and foremost by the space and its function: wet or dry? Formal or casual? How much wear will it get?

the floor dilemma

Our design teams faced similar quandaries when working out the details for the rapidway platform floor of the new Vaughan Metropolitan Centre Station [Viva bus rapid transit].

All of our other open air vivastations have tiled platform floors, so the obvious choice would be to use that in the new VMC Station. But this station faced an additional level of complexity, being built above the subway extension.

The top of the subway station extends to just under the vivastation foundation, providing limited depth to work with. Installing the tiles with concrete underneath as required would use up space needed for essential power and communications cables. A concrete floor became the ideal alternative.

durable by nature

Concrete flooring for the platform works better in the space we have, and the durability means less maintenance is required, saving money down the road. The VMC Station floor will be getting a lot of use in a relatively small space. We know concrete will perform.

But, we also want great aesthetics. Fortunately, concrete is also versatile.

Outside the station along the sidewalks of Highway 7 are paver stones laid in a distinctive pattern. Inside the station, we’re re-creating that look with concrete. First, we built the concrete molds to match the sidewalk, then poured each section with matching colours of concrete.

functions like concrete, looks like tile

Because the platform floor continues beyond the shelter of the vivastation canopy, we needed to ensure it’s not slippery. Before the concrete set, every concrete slab was given a hand-applied swirl finish to provide a measure of slip-resistance. We have also done decorative work on each section to create the appearance of tile.

Just like you’d want for your own home, the final result will meet design goals in every way: strong, durable, easy-to-maintain, and functional. And nice to look at, too.

taming the wind

One of the design considerations behind the new rapidway station at Vaughan Metropolitan Centre are the heavy traffic volumes on that stretch of Highway 7. It’s a busy area, and with all the exciting new development coming to the VMC, it’s only getting busier.

As we’ve talked about here, making people feel safe and secure while they wait in the vivastation in the middle of Highway 7 is one of our top priorities. But beyond providing a physically safe waiting place, we also want to provide a comfortable experience for transit users. So the new vivastation offers lots of options, whether people want to wait inside the glass enclosures, on the platform under the high roof, or on the outside platforms.

fresh air, no wind!

For those who prefer being out in the fresh air while they await their YRT/Viva bus, there will be planters of greenery and trees to enjoy, but with all that traffic whizzing by, some might have found it a bit blustery. That’s why we’ve installed special windscreens, on the north platform where the traffic comes closest.

windscreens as art

The seven windscreens are located just to the west of the station on the road-side edge of the north platform. At first glance, they appear to be art.  We certainly designed them to be attractive in their own right, although they are also capable of mounting outdoor art displays.  Curved like the sails on a boat, they’re framed in glass, with posts made of aluminum.

a peaceful wait

Although they look so decorative, they’re actually designed to be functional, and to make waiting on the outside platform a more peaceful experience.

So when you get a chance to visit the north YRT/Viva platform at the VMC, go stand near the windscreens, and see for yourself how we’ve been able to make standing outside a nicer experience, even in a breezy place like the middle of Highway 7.

safety in waiting

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.

a modern take on the ancient dome

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

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.

designed to connect: the VMC rapidway station on Highway 7

If you’re a Viva customer, you know that vivastations generally follow the same design, with a curved glass canopy providing shelter from the elements, and extending over the concrete platform and enclosed glass waiting area.

easy on the eyes

Elegant curves and expanses of glass, warmed by wood. Open and airy while still welcoming, human-scaled and sheltering — these are the main themes in the vivaNext design language. A vivaNext structure, whether it’s a vivastation, the towers at Bayview Station, or the Operations, Maintenance and Storage Facility [OMSF] in Richmond Hill, contain those recognizable elements and marry functionality with beauty.

We believe that taking public transit should be a great experience. It should be convenient, comfortable and reliable, but also aesthetically pleasing.

the biggest vivastation yet

So in keeping with this overall design goal, we’re excited to report the progress on the new bus rapid transit [BRT] station taking shape on Highway 7 in the Vaughan Metropolitan Centre [VMC] transit hub.

With the vivaNext curves as our visual starting point, we needed to tailor the design of the new station to its unique role: linking Viva passengers arriving via the BRT lanes in the middle of Highway 7 to the subway trains below and to the YRT bus terminal nearby.

connecting connections

Passengers connecting between the new Line 1 TTC subway and Viva literally don’t have to cross the road to get to the subway or the new SmartCentres Place Bus Terminal north of the subway station. Once in the station, stairways and escalators and elevators will make it easy to connect to the subway concourse level below, and to an underground pedestrian path connecting to SmartCentres Place Bus Terminal for YRT. For pedestrians and cyclists in the area, there’s also going to be street level crosswalks and a plaza on the north side of Highway 7 connecting to the subway station and YRT bus terminal.

Over the next several weeks, we’re going to be posting more information and descriptions of the wonderful new VMC BRT station, including its design and an introduction to its amenities. And then before you know it, we’re all going to be able to enjoy fully rapid transit connections between York Region and Toronto. That’s something to really celebrate!

the utility bonus

click here to see our YouTube video about utilities!

If you’re a regular reader of this blog, you’ve probably noticed how often we post a story on some aspect of utility infrastructure. That’s because, as much as our main focus is transit, relocating and upgrading utilities is a very significant  piece of our construction project just on its own, in terms of effort, time and money.

Most of our posts are about the complexities and challenges of utility relocation. But the most important story is about the bonus: at the same time as we’re building new transit, York Region residents and businesses are going to be getting new telecommunications, water, sewage, drainage, power and gas lines to power them into the future.

Unlike a single construction project with one overall manager, the utility project demands that many players work together collaboratively. Working within multiple agreements and relationships, our projects [funded by Metrolinx], the Regional and local municipalities, and the utility companies all work together to coordinate the utility construction.

Whereas York Region Rapid Transit Corporation leads the design decisions for the transit project, it’s the utility companies – including private companies and municipal utility companies – who determine what they need to meet the needs of their customers. Starting with our project’s alignment and overall design, it’s up to the utility companies to decide what infrastructure they’ll need as the population grows, and where it needs to go. For this, they need to take into account future development as well as current needs.

Because there’s not much room down there, and there’s a logical order to what goes in first, the utilities need to work out their plans in ways that work for everyone. In some cases they can jointly locate their services, but more often they need their own space within a separate trench or on an overhead line. Finally, they are responsible for carrying out their own construction, with only one crew able to work in a given area at a time.

Because we’re all equal players in this, coordinating activities requires us to work together, including our project team, the designers and construction experts working for the utility companies, and the various levels of government.

With every vivaNext corridor that gets completed, the end result is increased telecommunications capacity, upgraded water and sewage, better drainage, and new service connections to individual houses and businesses. That’s a future bonus that’s definitely worth the effort and a benefit for everyone.

what exactly is a ‘partial rapidway’ ?

what exactly is a ‘partial rapidway’ ?

Where there are dedicated rapidways in York Region, there are also transition areas to get buses in and out of mixed traffic – and something called “partial rapidways”. Here are some simple explanations of what will be happening with transit in these areas.

full dedicated rapidway

The typical rapidways are dedicated lanes in the centre of the road for buses serving specific Viva routes. Vivastations are located roughly every kilometre or so, with customers being able to access the stations via signals at intersection crosswalks. Rapidways will allow Viva vehicles to zip past regular traffic.

transition lanes

Transition lanes take the buses into and out of the centre-lane rapidway. A good example of this is on Davis Drive west of Yonge Street.

partial rapidway

For the purposes of the vivaNext projects, partial rapidway typically means dedicated bus lanes in one direction of a roadway only. For example, in the Bathurst & Centre area, there will be dedicated rapidway for the most part on Bathurst and Centre Streets, and partial rapidway in three locations:

  • On Centre Street between Highway 7 and Dufferin Street, there will be regular centre-lane rapidway going westbound, and partial rapidway eastbound (full rapidway starts part-way).
  • The rapidway on Bathurst Street over Highway 407 and Highway 7 will be one direction southbound. The northbound rapidway will end just north of Flamingo Road.
  • The rapidway on Highway 7 between Bathurst Street and Yonge Street will be one direction eastbound. The westbound Viva route will run in mixed traffic.

transit in mixed traffic

While a partial rapidway is still in the centre lane, when Viva bus routes run in regular mixed traffic, there are no designated lanes, meaning that buses will travel in lanes that are also used by other vehicles. This usually occurs along roadway areas that are more highway-like without a lot of residential or commercial development, and therefore not a lot of customers.

For example, on Highway 7 roughly between Bayview Avenue and Yonge Street, Viva buses exit the rapidway and rejoin regular mixed traffic. Also, in the short section along Highway 7 between the GO Barrie bridge underpass and Centre St., there is no road widening or improvements as the underpass is not being widened. Therefore, in this stretch, transit will be in mixed traffic.

curbside rapidway

The vivastation at Bayview Avenue is curb-side with two levels, to allow customers to transfer between east-west transit service on Highway 7 and north-south service above on Bayview Avenue.

Designing rapidways is complicated, but it takes into account the local area geography and the ridership levels, today and in the future. This ensures that vivaNext is building dedicated lanes in areas that will see the highest levels of improved travel times.

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.
