designing for the future

Who can remember? Not so long ago Highway 7 in Markham and Richmond Hill was a suburban highway: a few isolated developments, lots of parking lots and open fields, but no sidewalks, no plantings, no bike lanes–and certainly no dedicated rapid transit bus lanes. Just look at it now!

In only a few years from start to finish, construction begins and is completed on each of the rapidway projects. In the world of infrastructure renewal, vivaNext construction projects are known to be implemented very efficiently, and we’re doing everything we can to maintain that great reputation.

years of work are behind the design

What’s not so apparent to the public is the lengthy design process that happens long before construction starts. Design of the many engineering and architectural elements must take place stage by stage. Throughout, the designers need to balance staying true to the original vision with making it work in different conditions and geographical areas.

a variety of disciplines at work

VivaNext uses a multi-disciplined design team including: engineers who specialize in civil, traffic, structural, geotechnical, electrical and transit systems; architects; environmental consultants; landscape architects, security experts and more.

many stakeholders weigh in

At each stage, different options and features are reviewed, adjusted and improved with input from municipal staff, utility companies, local conservation authorities, property owners and others. Depending on the location of the project, specific design issues are addressed in conjunction with the owners of adjacent infrastructure including GO Transit, 407 ETR, CN, and the Ontario Ministry of Transportation.

the stages of each project

The process is not a fast one; the Environmental Assessment process, which established the conceptual design for vivaNext, was begun in 2002, and the whole process for any one segment from Preliminary Engineering to service start may take 6 or more years. Here’s an overview of the stages each of our projects go through, before shovels can hit the ground.

•    Environmental Assessment [EA]: The EA examines alternatives and identifies a preferred design. The vivaNext conceptual design shows the approach for individual segments like the number of rapidway and traffic lanes, boulevards and planting zones and the arrangement of stops and stations. The EA then identifies potential design impacts on the natural and built environment, traffic, noise, drainage, property, etc., and proposed strategies to avoid or mitigate and monitor them.

•    Preliminary Design: This stage takes design to approximately 30% completion and establishes the outlines of the project including its alignment and profile, what additional property is needed to build the project, development of major components like bridges or culverts for water crossings, entrances and intersections, utilities, and listing permits and approvals.

•    Detail Design: This stage fleshes out the preliminary design for all elements. For example, preliminary design may identify that a high retaining wall will be needed at a specific location; 60% design will show the kind of foundation needed and the wall’s general construction; 90% design will show the colour and design of the material to be used on the outside of the wall, and 100% will show all details and specifications required to construct the work.

•    Issued-for-Construction Drawings: These are the final design drawings to be used by the contractors, once all approvals are complete.

By the time vivaNext is complete, all our projects will share the original design vision, but their individual design will reflect local requirements and various conditions. Each segment is tailor-made to be functional, convenient and beautiful, with the primary goal of providing a rapid transit system for the future. Which is, and always has been, the ultimate vivaNext design objective.

Construction Rapidways Stations

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.

digging deep >> utilities at a glance

digging deep >> utilities at a glance

Before we can build dedicated rapid transit lanes, wider sidewalks, and plant beautiful greenery above ground, we need to go underground – to the world of utilities.

Our latest video peels back the layers to reveal all the modern conveniences we all depend on and often take for granted. We’ll shed some light on the steps we take to relocate critical infrastructure and explain why you see different crews come back to the same location as work progresses.

The most common things you’ll find are storm and sanitary sewers and pipes, water mains, gas mains, electrical wires, television/internet cables and phone lines.

We also take a look at the latest technology under the median and sidewalk planters , allowing trees and other plants to have deep, healthy root systems, and providing natural storm water management.

We’re just scratching the surface, but you’ll get a glimpse of how we replace and update infrastructure as an important investment that improves everyone’s quality of life.

the freedom of July

the freedom of July

July means freedom to kids and youth who are out of school, and spending time outside walking, biking and taking transit. It’s a time filled with the promise of new adventures and fun on the horizon.

We’re all for adventures, but with so much activity on York Region’s streets, we hope everyone will keep safety in mind too. If you’re out for a walk or bike ride, be sure to stay outside of construction areas – even ones that appear inactive. Cross at sidewalks, and be aware of vehicles nearby. If you’re driving, give pedestrians and cyclists some extra space and lower your speed in construction areas.

Most of our projects are on or near the road, so we’re very safety conscious when setting up construction sites.

When setting up work sites, our contractors abide by legislation, safety guidelines and local bylaws, including: the Ontario Ministry of Labour, Occupational Health and Safety Act [1990], Ontario Traffic Council [Book 7], and bylaws of York Region and local towns and cities.

Safety of the site and the construction workers is very important on any project. By keeping the community informed of work and maintaining good directional signs, the teams work together to make sure everyone gets home to their families.

We hope everyone finds a little adventure and a taste of freedom this summer – stay safe!

Construction General

what’s in a sign?

What’s in a sign?

Even with the most careful planning, construction zones pretty much always result in some delays and congestion for commuters, and we know that our vivaNext rapidway projects are no exception. We are committed to doing whatever can be done to minimize the impact of construction and keep people informed.

One way of doing that is to let drivers know if there’s congestion along their route, and if so, how much of a delay they can expect. By giving real-time information, drivers can decide if they should take an alternate route.

That’s why we install variable message signs, or VMS, on the approaches to our construction zones, including along Yonge Street and on Highway 7 near the Vaughan Metropolitan Centre.

Using Bluetooth Traffic Monitoring [BTM] software, these signs show actual travel times, in real time, between specific locations. Roadside sensors collect Bluetooth data from passing cars, and the information is uploaded to a central location. The software then analyzes the data to determine current travel times, which is reflected on the signs. In addition to travel time, project managers can update other information on the signs, such as upcoming work or lane closures.

BTM is able to detect Bluetooth signals emitted from cell phones, tablets and other Bluetooth or Wi-Fi devices on-board, and convert this into accurate information, simply and inexpensively. Not all vehicles carry devices with Bluetooth turned on, but there is a high enough proportion of devices to provide effective information.

Cars emitting Bluetooth signals are randomly chosen as they pass into the defined area.  Multiple sensors placed along the route detect the unique identifier of each Bluetooth signal and track it as it travels through the area. In this way, the system measures in real time how quickly cars are moving, and reports actual travel times. The software has built-in algorithms to make sure it only tracks vehicles while ignoring Bluetooth signals emitted from pedestrians or other stray sources. The information is constantly uploaded to the VMS, telling drivers exactly what’s happening on the route ahead.

The technology to use Bluetooth data to analyze travel times has been around for some time.  But vivaNext was actually the first project in North America and possibly the world, to collect and convert this information for display on variable message signs.

What’s in a sign? We know that the signs on their own won’t reduce the disruptions caused by construction. But by providing drivers with accurate travel time information, they’ll know what to expect for their commute.

Construction Rapidways

Yonge at heart

Yonge at heart

At 220 years old, Yonge Street is one of the GTA’s oldest roads, and before it was a road it was likely a trail. Since the beginning, it’s been improved upon and extended. Transit has always been a component of the street, starting with horse-drawn stagecoaches, then streetcars, trains and buses. It’s always been a local road that people walk and bike along, as well as a commuting road for longer distances.

Today, Yonge Street is changing again. We’re building dedicated lanes for transit – rapidways – in Richmond Hill from Highway 7 to 19th/Gamble and in Newmarket from Savage Road/Sawmill Valley Drive to Davis Drive. It’s part of a big plan for a seamless transit system in York Region and the Greater Toronto and Hamilton Area. The Yonge Street rapidway will connect to the Highway 7 rapidways leading to Markham and Vaughan, and to the future Spadina Subway Extension and Yonge Subway Extension.

Once complete, Viva service along Yonge will have faster and more reliable travel times, and traffic congestion will be reduced. Modern transit will be on the doorsteps of people living and working along Yonge Street, and the tree-lined sidewalks and bike lanes will make Yonge an even more attractive, vibrant place to walk, shop and ride.  With people at all stages of life using this important street, transit continues to play a key role.

There is a lot of work happening in 2016, and we’re keeping everyone informed. You can find facts and maps on the project page on our website, and we’ll be at some local community events this summer. We’re also on Twitter and Facebook, and we have some project videos on YouTube. If you would like to contact us directly, our Community Liaisons are available to talk. If you sign up for email updates, we’ll let you know when work is happening and you’ll receive announcements, project newsletters, and an invitation to an open house we’ll be hosting later this year.

Construction Going Green Rapidways

sowing the seeds on Davis Drive

sowing the seeds on Davis Drive

Trees are coming to Davis Drive! Crews are out making their way along the rapidway medians planting trees, shrubs and perennials to create a more attractive, welcoming streetscape. We hope to see buds and shoots blooming all around us in the coming weeks.

To give them the best chance for survival, we carefully choose the species of trees and plants, and plant them in a special planting mix developed by the Region’s Forestry Department, rooted in special soil cells. Even with this great care, nature is unpredictable and sometimes a few don’t make it through the winter. In this case our contractor replaces them under the two-year warranty we have for all of our trees, shrubs and plants. Trees and other green spaces have been shown in studies to have health benefits, build prosperity and increase safety, so they’re an important addition to streets in York Region.

The vivaNext project delivers more than just great transit. With all the plantings on Davis Drive it also reinforces York Region’s Greening Strategy as part of great community design. The strategy promotes actions that support healthy natural environments, and it plants the seeds of inspiration for cultivating sustainable communities.

#ThanksDavisDr!

Keeping with the green theme, May 7 was the Town of Newmarket’s Community Cleanup & Fun Day, and it was a stellar community event! People from all over Newmarket gathered together to pick up garbage and brighten their community by getting involved and getting their hands dirty [gloves were provided!].

We were there to do our part, participating in the morning cleanup and crushing icy snocones for everyone to enjoy. It was our opportunity to say thank you to the people of Newmarket for all their patience, understanding and feedback during construction.

There’s just a little bit left to do before we can call it done, and have a rapid transit system we can all be proud of. Thanks Davis Drive!

the murky world of underground infrastructure

the murky world of underground infrastructure

Property ownership and development are generally straightforward concepts: people or businesses own land, including any assets that are built on that land, and only they can decide when and if any improvements are to be made.

But what happens when the property is located underground, and the improvements are being made by someone other than the property owner? Welcome to the murky and confusing world of underground infrastructure, where ownership and decision-making are much more complex than above ground.

Underground infrastructure, which includes gas and power lines, telecommunications, watermains and sewers, is always owned by either a private company or the municipality. But generally utilities are located under roads or sidewalks, or on private property; utility companies typically do not own the land where their utilities are located.

In most cases underground infrastructure is located in the “public right-of-way”, including roads, sidewalks and boulevards. If a utility company wants to make a change to their own infrastructure, such as making a repair or increasing capacity, they need to get municipal approval before any work can be done. This “municipal consent” process is set out in legislation, and ensures municipalities can control and coordinate utility work on public lands or roads. This is critical, especially when utility work requires road closures or detours or will have some other impact on the public.

Municipalities also can set restrictions on when and how utilities can access their own infrastructure, to minimize impacts on the public and protect the municipality’s own infrastructure. For example, a municipality might impose a moratorium on changes to private infrastructure on newly built or repaired streets, so that new asphalt isn’t dug up.

In all cases, our projects spend a lot of time coordinating with utility companies to resolve any conflicts between the rapidway and streetscape elements we’re building, and the multiple utilities using the same space. In many cases, utilities can co-locate, for example telecommunications may share a common duct bank, and be buried next to hydro. Designs for all relocated utilities have to work with our vivaNext design, and in some cases where space is limited, working through the design process to fit in all the elements can be extremely challenging. Municipalities also have views on where they want elements located; the Region avoids locating utilities in their roadway, whereas local municipalities prefer to keep utilities away from the planters.

Once the design is established, a schedule is worked out with the Region or municipalities, specifying how long the utility work will take. Utilities are given a specified amount of time to close lanes as part of the final permit; even if the work is next to the road, lanes often need to be closed to give workers room to work safely. Our design-builders will coordinate construction work with the utility relocations, since only one activity can be carried out at a time in any given place.

The last but very important part of this complicated process is reducing the disruption for nearby residents and businesses. Once the design and municipal consent is complete, the utility and vivaNext community liaison team work with property owners to discuss access to properties while work is underway.

A lot of moving parts need to be coordinated and resolved before any underground infrastructure gets moved, but our teams are committed to coordinating these efforts with everyone’s best interests in mind.

Commissioning Construction Rapidways

warranty work >> ensuring quality for years to come

warranty work >> ensuring quality for years to come

When you’re building rapidways for generations to enjoy, it’s important to make sure that the end product is what we want.

Everything – from the paving stones on the sidewalk, to the glass in the canopies, to the red asphalt – is tested, inspected and verified by qualified engineers with a keen eye for detail. Anything that doesn’t make the grade is placed on a “deficiencies list” that the builder is responsible to remedy. That’s why you may see occasional construction activity in the first couple of years after infrastructure projects are done.

Project managers of infrastructure projects call this the warranty work phase – an opportunity to catch any issues so that they can be fixed while the infrastructure is still under warranty. It often takes all the seasons in a full year to see how things weather in our climate or perform once in use.

Much like when you buy a new house, it can take one or two years for the foundations to settle, and for you to make note of where the finishes are less than desirable. Then the contractor comes back to fix all the nail pops and cracks in the drywall, fill any gaps in the molding and repaint where necessary. It ensures that you are happy with the work, and you get the most out of your home. Warranty work is the same idea for our facilities, stations and rapidways.

On Davis Drive, we’re starting with the grinding and smoothing out of curbs, fixing paint finishes and filling small cracks, and of course taking note of anything else that needs work.

Whether you’re a regular transit rider, or are considering your first trip on the rapidway, know that we are working hard to provide you with a quality experience and infrastructure that’s built to last.
