our plants are born survivors

City living in York Region provides lots of advantages, from all the great places to shop, eat and live, to entertainment options, and of course the increasing number of employers choosing to locate here. But one advantage country living usually has over city life is the abundance of green, natural spaces.

Fortunately, we’ve all come to understand and appreciate the value of trees and landscaping in our urban spaces. More greenery is good for our air quality, increases property values, and can lower energy costs. It makes our urban spaces feel more welcoming and human-scaled. Plus, it just looks good.

greenery a vivaNext priority

For all those reasons, introducing more greenery and landscaping to the communities where we build our projects has always been a vivaNext priority. Plants are chosen largely for their practicality. Median and boulevard planters filled with lovely, healthy blooms and foliage look gorgeous. Median planters filled with sad, struggling plants? Not so much.

roadside plantings face tough ride

The challenge in getting more of the former and less of the latter, is finding plants that can cope with the often-inhospitable environment associated with roadside plantings. Roadside plantings have to cope with heavy doses of wind, pollution, and winter road salt spray. We’ve made an incredible effort to give our plantings every possible advantage, from the design of the planters, to the amount and type of soil, to the actual choices of trees and plants.

Some of the plants selected for our first projects didn’t thrive as well as we hoped, so we redesigned our plant selections for the rapidways. Now we’re using an even tougher group of plants with a built-in advantage: they already grow wild in this area. Many of the new plants are those you’ll find in rural York Region, growing happily along roadsides and around old farmhouses.

going wild at the VMC

Some, like sumacs, grasses and Kentucky Coffee trees [which isn’t really a coffee tree, but has pods with seeds inside that early settlers used to make a coffee-like drink], are native to parts of Ontario. Others, such as rugosa roses and daylilies, might have been planted many years ago by humans, but they’re so tough, they don’t need any help once they get established and are happy growing wild.

The new flowers, grasses, shrubs and trees, including those we’ve planted in Vaughan Metropolitan Centre, will add a beautiful green note to the Viva rapidways and stations. And because we’ve chosen these natural-born survivors, they should be green and blooming for years to come.

world-class transit a lure for big business (like Amazon)

The hunt for Amazon’s second headquarters is on, and two sites in York Region – the new Vaughan Metropolitan Centre and Markham Centre – are vying for the coveted prize.

World-class transit systems could be their ticket to success in this competitive bid process. Cities and regions all over North America are competing for the golden opportunity worth a US$5 billion investment and up to 50,000 jobs.

One of the top considerations for Amazon is simply logistics. With an influx of up to 50,000 potential employees at HQ2, the question becomes: how is that going work? The RFP noted a core preference for the new site to have direct access to mass transit: rail, train, subway, bus.

“In weeks of speculation and showdowns, a lack of transit connectivity has been one of the great presumed disqualifiers [for the Amazon bid],” writes CityLab’s Laura Bliss in her article Amazon’s HQ2 Hunt is a Transit Reckoning.

Here in York Region, we’ve been busy planning a strong rapid transit system, but the plan was never just about transit connections. The rationale behind vivaNext’s bus rapid transit network has always been that the rapidways are just part of the puzzle; an investment in long-term prosperity that helps attract businesses and foster economic vitality in communities.

We’re building it, so they can come.

In the Toronto Region RFP response, maps showcase transit connections for each proposed location. For Markham Centre and Vaughan Metropolitan Centre, the picture looks good. We’re beginning to forge the kind of transit connections that count when it comes time to move the masses.

The first subway is coming to our Region later this year with the TTC Line 1 extension serving Vaughan Metropolitan Centre. Three rapidways are up and running, including one serving the tech corridor in Markham Centre and a segment on Highway 7 East in Vaughan. Combine that with YRT/Viva buses and GO Transit, and we have great transit connections that are ready to serve the likes of Amazon, and other big businesses on the move.

So Amazon, if you want to come, our rapidways are ready for you! And take note, better transit systems ultimately translate into better quality of life. Employees spend less time getting where they need to be, and more time being where they want to be.

Whether at home or at work, that’s time well spent.

Bridge Expansion Construction Rapidways Technical Uncategorized

bridge expansion >> driving piles and pouring piers

When you go under a bridge, what do you see? Huge concrete columns – piers – that support it. The five-metre expansion of the bridge on Highway 7 West over Highway 400 is becoming fully visible as the new piers are completed. In the photo above you can see the three completed piers and crews pouring the concrete cap for the fourth.

Each one of these piers is held up with a set of nine piles. Piles are long poles driven straight down, until they reach a surface solid enough to hold everything above. In this case, the piles are each nine metres long.

In the photo, the tall piece of equipment beside the west abutment wall is the pile driver, which is – as you’d expect – used to drive the piles into the ground.

On top of the pile-supported-piers, there will be bridge footings, girders, and a wider deck to make room for cars and trucks – as well as buses on new vivaNext dedicated rapidway lanes and a multi-use path for pedestrians and cyclists.

While it’s true that piers are just a part of the bridge, the bridge is part of a road, which is part of a rapid transit system, which connects people to where they need to go.

Next time you go under a bridge, look at the piers that support it, and the engineering and construction that went into them.

We’re building rapid transit, and along the way making infrastructure – built to last.

what’s gravity & slope got to do with it?

While we’re building the rapidway projects, it’s not unusual for us to be talking a lot about retaining walls. If you’ve ever wondered why so much of our work seems to involve retaining walls, the answer can be summed up in two words: gravity and slope.

Simply put, retaining walls prevent soil from sliding down a slope. If a slope is very gradual as you might see on a lawn or wide flowerbed, for the most part the soil and earth pretty much stays put. But where there is a slope over a short distance that creates even a difference in grade, the force of gravity will make the soil slide downwards.

stopping soil slippage

The steeper the slope, the more likely it is that the soil will slide. If you have a lawn that’s even a few centimetres higher than an adjacent driveway or sidewalk, you’ll know that without some kind of edging, eventually the dirt will flow down onto the pavement.

Retaining walls are like edging; they’re structures that keep the soil in place where grades need to change within a short distance. And retaining walls can be short or high. For example, a curb is essentially a very short retaining wall.

where retaining walls fit in on the rapidway

In many stretches along our rapidway construction zones, the adjacent land is either higher or lower than the roadway – in some cases the difference is only a few centimetres, in others it’s a metre or more.

Because we’re widening the road, that difference in grade level now has to be made up over a shorter horizontal distance, making the slope steeper than it was before. In areas where the resulting grade difference between the road and the land slope is very steep, a retaining wall is needed to keep the soil in place.

where design is king

Some of our retaining walls are essentially high curbs; others are high structures requiring handrails and complex foundations.

Every one of our rapidway segments has a significant number of retaining walls, each requiring its own design, approvals and construction process. In all cases, retaining wall construction takes place once utilities have been moved out of the way, and needs to be finished before road widening can be started.

With so many retaining walls forming part of the new streetscape, design considerations are of major importance. A lot of effort goes into ensuring that the new retaining walls contribute to the aesthetics of the streetscape as well as be functional.

Different materials and finishes are used for different walls, from pre-formed wall blocks similar to what you’d use in your own garden, to poured concrete with decorative exterior designs.  Design approaches vary depending on how high the wall is, what kind of foundation it requires, and what it is adjacent to. And if the wall or adjacent slope is especially steep and the wall is next to a sidewalk, it will also get a specially designed handrail.

So the next time you see a bulletin advising about retaining wall work, think of gravity and slopes, and you’ll know that’s why we’re building these additional structures.

Bridge Expansion Construction

the expansion of the Highway 400 bridge on Highway 7 West begins

Many of you have already noticed the work that has begun on Highway 7 West at the bridge over Highway 400, so here’s an overview of the components of the newest mega-feat of engineering that you’ll see happening over the next few years.

The project is part of the Highway 7 West rapidway project in Woodbridge-Vaughan and it will include expanding the bridge – with the new segment added to the north side – by approximately 5 metres.

New piers

Construction includes four new piers to support the expansion, which means new foundations, footing and forms. With multiple lanes above and below, this is a complicated project and safety is paramount for both the travelling public and the workers on site.

Huge girder lift

In September, the first piece of a gigantic girder will be lifted into place. This girder, which is needed to support the expansion of the bridge, will be installed in five pieces.

Multi-use path and rapidway

What makes this project especially remarkable, is that it will not only include dedicated red-asphalt bus lanes, but a pedestrian and cycling path will be constructed in the centre of the bridge between the bus rapidway lanes. Once complete, the bridge will provide roadway and connections for all types of transportation modes.

Realigned ramps

That’s not all. In addition, two of the ramps on the east side of Highway 400 will be realigned in order to accommodate potential future development. And to accommodate the waterway conditions in the area, new culverts will be built under the new ramps.

You’ll be hearing much more about this massive undertaking as time goes on. Next month, we’ll look more closely at what’s involved in expanding the bridge itself – think piers, pile drivers and parapets!

the unique challenge of working around business, residential and other private property

When you’re talking about private property, chances are you’re picturing someone’s home or business, or maybe a piece of land with a fence around it. But did you realize that every square inch of York Region, as in every other jurisdiction in Canada, is actually owned by someone?

Typically, for projects like vivaNext, when work will be taking place on or near private property, we work with a range of property owners, whether it’s a private individual’s home or business or a different level of government. Here’s how it works:

During the earliest design phases, we map out the proposed design for the future roadway or facility, working with existing information about property ownership. For the most part, rapidways and facilities are intentionally designed to fit within property that is already owned by the future operators of our projects – for example, the Region of York or one of our local municipalities.

As the design process gets more detailed, we analyze how the proposed alignment will fit with the properties along the roadway. We also identify any impacts the project will have on each.

In some cases, such as where the road is being widened, the recommended design may show that we might need to encroach onto private property. Sometimes we may only need access onto private property during construction, and sometimes it’s permanent.

With the final design established, and depending on the nature and duration of the property impact for each property, we then follow a series of established procedures to come to an agreement with the owner.

The agreement will include clarification of how our work will affect their property, how long we’ll need access if it’s only temporary, and compensation if we’re acquiring some part of their property.

The options and arrangements will vary depending on the kind of property and what impact our project will have on it; for example, installing a rapidway across a bridge over a 400-series provincial highway will involve different issues and potential strategies with the property’s owner or representative. In this case, it’s the Ministry of Transportation on behalf of the Province of Ontario.

In all cases though, the process of working with property owners to work out access is a complex part of the design and pre-construction work, and involves many different team members including York Region Property Services, Legal Services, York Region Transit, our design builders as well as our project team.

But no matter who the owner is, being respectful of the rights of all our property-owning neighbours is a top priority for our project with dedicated staff like the Community Liaisons to help answer questions in the field.

a look back at the CN MacMillan Bridge expansion

As work starts up on the Highway 7 bridge over Highway 400, which is being widened to accommodate rapidway lanes and a multi-use path, let’s take a look at a completed bridge expansion project: the CN MacMillan Bridge.

The Highway 7 bridge passes over the CN MacMillan Rail Yard, the second-biggest rail yard in Canada.

The expansion project, which was part of the Highway7 West-VMC rapidway project, involved widening the bridge by 8.5 metres to accommodate the two lanes of rapidway that opened in February 2017.

Crews poured 4,000 tonnes of concrete to build abutment walls, piers, foundation and piles, sidewalks and decks; embedded 300 tonnes of reinforcing steel; and built a new pedestrian sidewalk and hand-rail and bike lanes!

All of the work expanding the bridge had to be done – and was accomplished – without stopping the trains or impacting the 10 sets of tracks. For safety purposes, before construction even began, crews had to rehearse set-ups and take-downs with numerous safety drills so it would proceed like clockwork.

During construction, crews worked very closely with CN to coordinate work around train schedules. An additional challenge was the fact that the rail yard, which handles one-million-plus cars per year, also operates 24/7.

Mega feats of engineering and construction like the CN Bridge project are beginning again with the expansion of the Highway 7 west bridge over Highway 400. Next month, we’ll take a look at the different components of work involved for this project.

Construction Rapidways Safety

pedestrian safety

When there’s something on the other side of the street you need to get to, the nearest intersection might not seem close enough. It can be tempting to cross (or jaywalk) in the middle of the road. The problem with jaywalking is that it poses a risk to you as a pedestrian. Drivers aren’t expecting pedestrians in non-pedestrian areas, and may do something unexpected – or not brake in time – for you to cross the road safely.

During construction, crossing at designated crosswalks is even more important than ever. Lane closures can change frequently and when areas are blocked off, drivers must pay close attention to signs and road markings. Drivers might easily miss a pedestrian who is crossing or running into a non-pedestrian safe zone.

Even when crossing at a designated crosswalk, it’s important to keep safety in mind. Be sure to look both ways and stay aware. Put away your phone or tablet, and focus on the road. You should be constantly alert, just like the drivers.

For pedestrians, other safety concerns include the construction zones themselves. There are a lot of hazards around a construction site that you wouldn’t necessarily know about. We block off these work areas and create detours to protect drivers and pedestrians, so it’s important that you respect those boundaries for your own safety.

Construction Utilities

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.

sneak peek >> what’s to come

sneak peek >> what’s to come

Have you ever walked past those construction sites surrounded by wood walls, and wanted a peek inside to see what’s being built? Curiosity is good – it helps us to move forward and to try new things. In York Region right now, we have a chance to sneak a peek at what’s to come.

In some cases, it’s right out there in the middle of the road. Communities with rapidway construction underway can see how their street will look once it’s done, by looking at Highway 7 East in Markham and Richmond Hill or Davis Drive in Newmarket. It’s more than bus lanes – it’s new utilities and infrastructure like bridges, tree-lined sidewalks and where possible, bike lanes.

In Vaughan Metropolitan Centre [VMC], we can see the transit hub on the way in the next year that will include a super-sized vivastation in the centre of Highway 7, linking to a YRT bus terminal via an underground pathway and above ground plaza, and connecting directly to the new subway platform below via escalator and elevator.

We can even get a peek at the new subway stations that are part of the Toronto-York Spadina Subway Extension project. TTC is hosting a Doors Open Toronto event this Saturday only, at the new Downsview Park Station and York University Station, set to open for service at the end of 2017. Information about the event is available on the project website, and if you can’t go, be sure to take a look at the photos posted by project staff on their Flickr site. And check out this TTC video of the future subway ride from Downsview Park to VMC, recorded last year to celebrate the final tracks being laid.

So if you’re curious about the subway, be sure to visit Downsview or York University Stations this Saturday. And if you’re curious about transit in York Region, feel free to ask us a question or follow us on Twitter, Instagram or Facebook.
