We’re excited to share that concrete pours for the Level 1 (L1) suspended slab are underway! The first pour was done on January 25 and the remaining pours will continue until mid-April. Once all 10 pours for L1 are complete, ~2510m³ of concrete will have been poured.

Fun fact: Heidelberg Materials, Dawson Creek is supplying all of the concrete for the suspended slabs and CanaSteel Rebar Services, Dawson Creek is supplying and installing all the reinforcing steel.

Suspended slabs are upper floor concrete slabs that are not in direct contact with the ground. The slab is supported on the exterior of the building by foundation walls and on the interior by concrete columns.

In anticipation for the suspended slab pours, Graham had to complete the foundations that serve as the supporting structure of the slab. This installation involves:

• Mudsill installation – Lumber used to support shoring. Mudsills distribute the shore load across an area big enough to not exceed the allowable soil bearing pressures.
• Shore Installation – Vertical support designed to carry the weight of the formwork, reinforcing bar, concrete and live loads. All engineered to known and assumed loads. For DCDH, we are using an engineered tower system.
• Beam Installation – Aluminum beams for horizontal formwork that are supported by the shores.
• Joist Installation – Horizontal formwork installed perpendicular to and supported by the beams. The form facing material (plywood) is placed directly on the joists.
• Formwork installation – The sheathing or plywood as mentioned above is what the concrete will be placed against.

For the most part, the shoring is built in place. The beam, joist and formwork are pre-assembled as much as possible and flown in place using one of the two tower cranes on site. Infills are then completed after the prefabricated pieces are installed.

The L1 suspended slab formwork is a tower system, so after the slab section has been poured, the beam, joists, and formwork will be removed and used on future pours. The shores will be lifted and individual reshore posts will be placed for the duration of all of the suspended slab pours for all levels.

As usual, there is a lot of preparation work that goes into the suspended slab pours beforehand. In addition to engineering and picking an appropriate system, extensive planning for heating and hoarding is required to ensure the concrete cures properly. For suspended slabs, heating comes from the bottom which allows the concrete to be placed and finished and then the top of the slab is covered with tarps to keep the concrete at the right temperature and prevent moisture evaporation.

The size of the pours are also pre-planned to accommodate:

• Concrete supply capabilities – Slab sizes are based on the amount of concrete that can be received in a 6-to-8-hour window
• Reinforcing steel laps and layout – Splices in rebar can impact structural integrity and increase loads outside of design parameters
• Engineered control and expansion joints – Allow for shrinkage or movement
• Crew availability and floor requirements – Levelness, flatness and finishes all have different levels of support and manpower required
• Ambient air temperature, heating and hoarding

The Level 2 and Level 3 suspended slabs consist of 18 pours (9 per level) totalling over 5000m³ (2500m³ per level) of concrete. Level 2 is anticipated to occur from March to May and Level 3 is anticipated from April to July.

Project status update

Where we’re at

Since our last update, work has been progressing well on the site of the new hospital – partially thanks to the mild weather we had heading into the holiday season!

During October, detailed excavation was completed and over 2,200m³ (about the volume of an Olympic-size swimming pool) of concrete was poured.

During November, construction activities transitioned to vertical components such as elevator cores, columns, and foundation walls. The second tower crane was also installed – check out this timelapse video of the process.

During December, work began on foundation walls, interior columns, gas and electrical set up for site heating, and backfill of deep foundations.

In addition, Graham prepared for the winter months by implementing their frost protection, ground heating and new temperature monitoring systems.

What’s next

Over the coming months, construction activities will continue to focus on the concrete superstructure and work has just begun on the level 1 structural suspended slab.

In March, we will receive and review the formal 95% design submission and host the third round of mock-ups in the Quonset hut.

With an investment value of approximately $590 million, the DCDH project is ranked #92 on the list of the top 100 biggest infrastructure projects in the country.

The 2024 Top100 Canada's Biggest Infrastructure Projects Report is an annual report published by ReNew Canada, an infrastructure magazine that ranks and profiles the country’s largest public infrastructure projects.

Upon completion, the new hospital will be more than 25% bigger than the current facility – strengthening existing services and supporting increased access to care for all Northeast residents.

Graham Design Builders prepared for the winter months by implementing their frost protection plan to maintain temperature levels of the foundation subgrade, thereby allowing concrete work to continue through the winter and protecting the ground from frost. This included procuring and installing ground thaw machines and natural gas lines.

Graham has sourced a new-to-market temperature monitoring system to complement the ground thaw machines. The new system provides real-time temperatures of the subgrade to their cellular devices and allows them to turn down or shut off the heaters when they’re not needed. It also ensures compliance, reduces costs, and helps the environment.

Graham has taken a different approach to ground heating with the use of natural gas instead of diesel. Natural gas is more reliable, cleaner to run, eliminates greenhouse gas emissions from regular fuel deliveries, and reduces the amount of greenhouse gas producing fuel being used. Diesel units can have limitations, be prone to mechanical issues in colder weather, and typically run for shorter periods of time to remove frost as opposed to preventing it.

Typically, a ground thaw machine is supplied and installed as a single all-in-one unit. Graham acquired a system that was installed as individual units that work in unison to run cleaner and limit potential re-work or replacement. Individual units also keep a consistent heat to the multiple lines to prevent frost and reduce the volume of glycol that would typically be lost in the event of a line failure.

How does the ground thaw system work?

• There are five individual glycol boilers, and each boiler is 1.8 million BTU.
• The boiler heats the glycol and supplies a fluid exchanger pump with a 2-inch supply and 2-inch return line – which is the main heating element of the system.
• The hot glycol runs through the plate exchanger and back to the heating unit.
• The use of the fluid exchanger pump keeps the fluid from the heating unit separate from the fluid in the field.
• From the fluid exchanger pump, 2-inch supply and return hoses are connected to 2-10 port manifolds.
• From the manifolds, soft ¾-inch glycol lines are connected and run for a maximum length of 1,000 feet.
• This creates a full system where the glycol is pumped from the heating unit to the fluid exchanger pump, which then heats the glycol that’s circulating through the ¾ hose and manifolds therefore resulting in warm, frost-free ground.

How does the new temperature monitoring system work?

• The temperature sensors are placed strategically throughout the site and at various depths.
  • The depths are chosen based on the depth of the footings – some are placed at the bottom, some in the middle, and some shallow.
• A cellular enabled control node collects data at a set frequency (ex: 15 minutes) and then the information is sent to the Cloud where Graham can access the data.
• From the control node, there is an expansion box that can be hooked up to six temperature sensors.
• The system also notifies Graham automatically if/when temperatures drop below a certain set threshold.

The holidays are just around the corner and everyone deserves a little break!

Our project team members are taking some much needed time off after a busy year of major milestones. They'll be spending time with their families, celebrating the holidays, and re-charging for the new year - and we hope you get to do the same! Work on site will also slow down between December 22 and January 2.

We wish you and your loved ones a happy and healthy holiday season and new year!

Stay tuned for more updates on the DCDH Project in 2024!

The Project Management Office decorated their construction Christmas tree to get involved in the holiday celebrations at the hospital.

If you’ve driven or walked by the site of the new hospital recently, you might have seen a sea of vibrant orange tarps across the site. Graham is planning and preparing for the winter months and starting to implement their frost protection plan.

It’s fundamental that heat and moisture control is addressed throughout the construction process during the winter months. This includes controlling the temperature and protecting the concrete foundations to avoid a negative impact on the quality of the installation and possible re-work, if not done correctly.

One of the biggest risks during the winter is the frost impact to the deep foundations. Planning and executing the plan has already started and will be an ongoing effort throughout winter. This includes:

• Installing and managing over 800 – 12x24 insulated tarps
• Procuring and installing five 1.8m BTU glycol ground thaw machines that provide heat to over 80,000 lineal feet of glycol lines
  • The glycol lines are spread throughout the foundation subgrade to maintain temperature levels
• Installing a 30-pound natural gas line to the site with a 5-pound distribution centre to 12 locations across the site footprint
  • This ensures there is a fuel supply to any location that heat is required for frost protection
  • It also supports concrete pours throughout the winter
• Elevating stored materials to ensure they don’t freeze into the ground
  • Materials are marked so they know what it is and where it is, in the case of heavy snowfall

Safety of the people working on or visiting the construction site remains a priority. Winter weather creates different challenges and risks that have to be eliminated and controlled, and colder temperatures and snowfall changes how work is done on site.

Special equipment, tools, and materials are procured in preparation for the winter weather including snow shovels, ice melt, sand or rock chips, and skid steer attachments. Snow clearing is completed before shift start to limit interaction with the public and construction personnel. Workers are constantly clearing snow, removing ice, working on safe access over tarps, moving heaters and glycol lines, setting up hoardings and running extension cords.

The amount of planning hours and labor-intensive work that goes into preparing the site for winter helps ensure that workers and visitors can safely gain access to the construction site and work safely at all times.
