why vivaNext staff do ‘walk-downs’ of our construction sites

constructions workers reviewing a roadway construction site for a transit project

Blog post by: Elizabeth Kim

Have you ever seen a group of people with white hard-hats walking along a rapidway construction site, although it seems like there isn’t much construction happening? Have you ever wondered, “How many people does it take to look in a hole?” or, “Why is everyone just standing around and talking?”

Well, we hope to help answer those questions.

getting a closer look

The constructor schedules regular walk-downs of each of our rapidway construction projects – from one end to another – in order to closely review completed, ongoing and upcoming work. Different walks have different purposes, including safety monitoring, the quality of work in progress and the quality of completed elements to ensure everything works as intended once the rapidway opens for service.

That’s not all. As we get closer to a project’s completion and opening for service, the number of walk-downs goes way up to ensure that everything has been built according to plan in order to ensure that projects can be opened for service to the public. Here are some answers to the two biggest questions about walk-downs:

why so many people?

Each team member on a walk-down has a specific job. And depending on the purpose of the walk-down, a variety of people with different expertise may participate.

To review an area before a major work operation, for example, the walk-down team may include a vivaNext Project Engineer, who would ensure that the work plan is accurate to engineering drawings; and the Community Liaison, who communicates the impacts to businesses, residents and other stakeholders.

It may also include an Engineer from York Region’s Transportation Services, who inspects the roadway elements – such as street lighting, sidewalks, boulevards, traffic signals, pavement markings, and signs – and ensures compliance with lane closure permits;

Safety Managers ensure that the work plan is safe. And Supervisors from the Constructor and sub-contractor companies take everyone through the work plan and operation.

In some cases, municipal and regional staff will join us on inspections– for example, with water main connections, vivastation construction, paving, and red asphalt in the rapidways; and for works near Highway 400, provincial Ministry staff may join the walk-down.

what are they looking for during a walk-down?

Participants are looking at a variety of factors based on their role within the project team, and depending on the particular purpose of the walk-down.

Some participants are specifically looking for possible errors in construction – in new pavement, installed signs, storm sewers, and other quality concerns to be addressed.

All items are documented and while some items may need to be fixed immediately, others will be addressed during the contractor’s warranty period. Other participants look for how the operation will unfold and the impact to the community, such as accessibility for pedestrians. Follow-up walk-downs are then scheduled to review progress on documented items.

Each participant on a walk-down plays an important role in order to deliver high-quality rapidway projects throughout York Region.

viva la winter!

Brr, it’s cold out there, or unseasonably warm, depending on the day. You never know what’s in store. Regardless of the weather, our construction crews continue to expand the Viva rapidway system to improve connections in York Region. The winter season lends itself to certain types of work, especially the kind that happens above ground.

shiny, new canopies

Forget the January blahs! It’s been exciting times on the Bathurst & Centre corridor this past month. The first two vivastation canopies were installed at Bathurst/Hwy 7 Station located on the Bathurst connector road, one for each side of the station. There’s nothing like seeing that crane lift the canopy into place!

The elegant, arched glass canopies evoke traditional European transit infrastructure, transforming the everyday experience of transit into a beautiful one. A third canopy is coming this winter to the vivastation on Bathurst at Atkinson Avenue.

Looking to the west, construction of the first vivastation platform is beginning to take shape at what will be Commerce Street Station on Highway 7 West.

On both Highway 7 West and Bathurst & Centre, road widening and construction of storm sewers, retaining walls and culvert work is underway. Winter is also a great time to relocate hydro lines and install new poles, which is getting close to being completed in this area.

signals, check!

Our Yonge Street projects are not as far along, and the underground utility work they need to do is limited during cold weather. Crews have made some progress on installing underground duct banks and gas mains in Richmond Hill. Traffic signal work, a good above-ground winter activity, and is also underway. In Newmarket, crews are preparing to start work on the east side of Yonge when the weather gets a bit warmer. They’ll be replicating the road widening that was performed on the west side last year.

planning season

Winter is also a great time to make plans, large and small. We’re working together with the TTC on design and engineering for the biggest plan of all – the Yonge Subway Extension. Also, our staff and contractors are carefully planning spring construction schedules for the Viva rapidway projects, coordinating in advance with stakeholders, and procuring contractors for other projects.

Come spring, our crews will be raring to go, full steam ahead. If you’d like to keep on top of what’s going on in your community, we invite you to sign up for updates.

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.

a year on Yonge

a year on Yonge

‘Tis the season when we sit back and reflect on the year which has passed and prepare for the year ahead.

2016 was a big year for utility work on Yonge Street in both Newmarket and Richmond Hill. Gas and telecommunications installations were completed in Newmarket and water main and gas work made significant progress in Richmond Hill.

Through all of the construction barrels, mud, noise and mess on Yonge Street, we took pictures every step of the way and put together a video which captures the progress of rapidway construction in both Newmarket and Richmond Hill.

It is amazing to look back and remember all that can be achieved in just one short year. We look forward to another productive year in 2017!

connecting the drops

connecting the drops

The importance of upgrading Canada’s infrastructure is everywhere in the news these days. Infrastructure includes everything from bridges to roads and transit, to utilities such as hydro lines, sewers and water mains. Each vivaNext project includes improvements to infrastructure and utilities, leaving a lasting legacy for residents and businesses. One of the most important pieces of infrastructure is a water main – bringing fresh water to your mealtime prep, your kids’ bath tub and even your local swimming pool. In Richmond Hill, the residents and businesses connecting to Yonge Street are getting a new, modern water main to prepare for future growth.

Although to some people it might not seem very glamorous, an important example of a major infrastructure improvement is the replacement of the Richmond Hill water main, which we’re doing as part of the vivaNext Yonge Street rapidway project. This work will replace 3.7 kilometres of water main along Yonge Street from just south of Garden Avenue [north of Highway 407] to Major Mackenzie Drive. The water main, which supplies water to the adjacent residents, is owned and maintained by the Town of Richmond Hill, with construction done by the vivaNext Design Build contractor.

Water main replacements, especially in busy thoroughfares like Yonge Street, require complex planning for design, staging and construction. As with all our work, we need to find a balance between a number of competing priorities. One priority is to maintain service to households and businesses who depend on the water main. Another priority is to get the work done in a way that minimizes disruption to traffic. And, as always, we need to plan the design and construction in a way that gets the most value for money, including future maintenance costs.

To avoid existing underground utilities and simplify construction, we’ll relocate the water main to run under the traffic lanes on Yonge Street. We also want to avoid locating it under the new planters that will be built along the sidewalk, in the event that future maintenance on the water main is needed.

Replacement water mains are generally located as close as possible to the original water main, to preserve existing connections to residences and businesses. As a result, construction proceeds more slowly to avoid any damage during excavation to the existing water main, which stays in use until the new one is ready for service.

To minimize disruption to traffic, workers will be building the new water main from inside a trench box, which significantly reduces the amount of space needed to carry out the construction compared to regular excavation. The benefit of constructing in less space is that fewer lane closures are needed during construction, which is critical on Yonge Street.

However, trench box construction has to move more slowly. The rigid trench box also makes it more challenging to work around conflicts with other buried infrastructure. From time to time we can expect progress to slow down while crews get around other underground utilities. Construction will be followed by a lengthy process of pressurizing, cleaning and testing, all to meet very strict government standards.

Once the new water main is ready to go, a new connection to each address along the main route will need to be made, along with additional connections to other water mains at intersections. Individual addresses are relatively straightforward to reconnect, but businesses and multi-unit residential buildings take longer, with connections to larger pipes and fire lines. This process of disconnection and reconnection will be planned ahead, with communication with each residence and business to minimize disruption.

We’re excited that the community is going to be getting a new water main, built to the most modern standards. Our team is working with the community during construction to help minimize any impacts to parking and driveways. And we’ll make sure there’s lots of clear signage to help guide you through construction areas.

It’s a huge project, and it’s going to be pretty messy out there for a while. But long term, it’s great news for the residents of Richmond Hill that this huge investment is being made in infrastructure. We hope this helps explain what the crews are doing out there, and how it makes a difference to the community.

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 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.
