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.

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.

a connected transit terminal

a connected transit terminal

This morning, we marked the beginning of construction for a new YRT bus terminal in Vaughan Metropolitan Centre [VMC]. The news release gives the basic project information, but doesn’t delve into how this terminal will connect in the GTA transit network:

bus

Well, it is a bus terminal. YRT buses will use this terminal, taking customers in and out of York Region’s neighbourhoods and to places farther away like Brampton and northern Toronto. Customers will also be able to walk to the VMC vivastation in the middle of Highway 7, where Viva will take them away on dedicated bus rapid transit lanes. They’ll walk about two minutes above ground, or when the weather is frightful they’ll take the underground path and escalator, elevator and stairs to reach the vivastation.

subway

Customers will take the underground path or walk along landscaped paths outside to the VMC Subway Station entrance just south of the terminal, to access the underground concourse for the Toronto-York Spadina Subway Extension. The subway concourse is actually under the vivastation on Highway 7 – stay tuned for a future blog about this.

walking and cycling

The VMC area is planned as a walkable area with tree-lined sidewalks and places to live, work, shop and take transit. The terminal will meet accessibility standards, and customers will be able to walk or cycle there from any direction.

driving

The terminal is near the intersection of Highway 400 ad Highway 407, so a passenger pick-up and drop off [aka. “kiss ‘n ride”] will be included, encouraging carpooling.

 

So it’s not your typical bus terminal and it’s more than a place to wait for the bus. It’s about connections, and where they’ll take you from here.

working day and night

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

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.

form meets function where Viva meets the subway

form meets function where Viva meets the subway

There’s a lot happening near Highway 7 and Jane Street right now. With the subway extension, bus rapidway, bus terminal, and commercial and residential buildings being built, it’s difficult to distinguish one construction project from the other. In the past week though, one project has become more visible.

In the middle of Highway 7, between Jane Street and the Highway 400 ramps, a huge structure is being built. The VMC-Spadina Subway vivastation will play an important part of this transit-oriented area, connecting Viva customers to the subway below.

The station is supersized with longer and wider platforms, and the roof will cover the entire rapidway. Customers will be able to access the concourse below via elevator or stairs to access the new subway extension or walk a few minutes underground to catch YRT or Züm at a new bus terminal.

A few fun facts about the station:

  • Single canopy is 50m long x 22m wide – bigger than the other vivastations to accommodate more bus and passenger traffic.
  • Steel structure assembled as three roof sections [now installed]; eight ladder sections [the first just arrived]; and 70 smaller infill sections.
  • Uses a combination of aluminum, painted steel, ceramic frit and tinted glass panels – overall, the station will appear light grey with blue and white accents.
  • Up-lighting will illuminate the lattice pattern of steel supports and glass panels on the roof.
  • Real-time bus arrival screens in station waiting areas, and underground at concourse level.
  • Heated and unheated waiting areas on each platform.
  • 100% coverage by security cameras.
  • Windscreens to block the prevailing wind – potential showcases for public art.
  • Hidden rainwater gutters and downspouts to drain water under the roadway.

The steel structure can be seen in the middle of Highway 7, and this will take a couple of months to put into position, and another couple of months of welding. As you’ll soon see, this station will make the Vaughan Metropolitan Centre area look very different. And once it opens in 2018, will connect everyone to where they need to go.

where will the vivastations be along Bathurst & Centre?

where will the vivastations be along Bathurst & Centre?

We’ve heard your questions about vivastation locations along Centre and Bathurst Streets, so here’s everything you need to know…

The Phase 2 rapidway project will include 10 new vivastations, with five of them along the current Viva bus route on Bathurst and Centre Streets. This is already one of York Region’s busiest Viva routes, so stops were planned where people will want to get on and off Viva.

From west to east, this is where the stations will be:

  • Centre Street at Dufferin Street.
  • Centre just east of Carl Tennen Street & Vaughan Boulevard.
  • Centre at North Promenade & Disera Drive.
  • Bathurst Street at New Westminster Drive.
  • On the connector road between Bathurst and Yonge Street.

As with all rapid transit in York Region, we plan stations to be walking distance from shopping, important services, and places to live and work. When it’s all done, the Centre and Bathurst area will have updated utilities and traffic signals, tree-lined streets and bike lanes. Preconstruction starts this year, including utility locations and relocations, and watermain upgrades.
