Stantec Tower Case Study

Building Stantec Tower Using Internet of Things (IoT) Sensors

PCL Construction built the largest tower west of Toronto, Stantec Tower, in North America’s northernmost metropolitan area with a population over one million. This project provided some unique challenges that required a smart construction approach. PCL relied on Job Site Insights™ (JSI™) Latium Technologies’ smart IoT construction platform.

About This Smart Construction Project

Located in Edmonton, Alberta, Stantec Tower is a 69-story mixed-use building designed to LEED® Gold certification. The building has 28 stories of office space on the lower levels and 483 premium residential units—the Sky Residences–on the upper levels. Stantec Tower is part of Edmonton’s ICE District, Canada’s largest mixed-use sports and entertainment district and was completed in 2019.

Construction Challenge: Temperature Control Using IoT Technology

With 69 stories, upscale finishes and grand design elements such as a lobby that opens into the public plaza providing access to the adjacent Rogers Place and Ford Hall, Stantec Tower was a complex project with a tight multi-year timeline. A multi-year project in Edmonton comes with environmental challenges: the potential for 70-degree Celsius temperature swings over four seasons. Temperatures must be controlled with heaters to ensure optimal conditions for millwork and other material installations, and to mitigate cold weather pipe burst risk. With 1.2 million square feet, the task of monitoring conditions manually could have proven as grand as the project itself.

How Iot Sensors Save Construction Companies Money

The Stantec team used Job Site Insights™ to get the real-time data and analytics that help construction companies build smarter, leaner and greener. JSI™ is a smart IoT construction platform that brings digital sensor and analytics capabilities to construction’s workface. IoT sensors installed throughout a project monitor vital construction conditions and alert job site personnel to adverse conditions that can lead to costly damages and rework. JSI™ virtualizes and models a job site, mapping sensors, equipment, assets and people to a single view accessible from any PC or mobile device.

JSI™ helps construction builders and general contractors get actionable, real-time insights and predictions into the construction project. This allows them to adapt to changing conditions, increase worker safety, enhance project efficiency, reduce energy consumption and avoid costly insurance claims and rework.

The Process of Installing IoT Sensors on a Smart Construction Site

Smart sensors were installed throughout Stantec Tower during construction. The sensors were programmed with specific temperature, humidity, pressure, concrete strength/maturity and leak detection parameters then mapped out and installed during construction, and in convenient and discrete locations throughout the hotel and residential suites, public corridors, lobbies and mechanical and electrical rooms to capture and record data. The JSITM interface created a virtual model of the site to map the data and sensors to the model. The project team monitored indoor environments in real-time through a mobile device or PC to confirm that interior areas were ready for materials to be installed per the project quality and safety requirements.

“It’s great to see the construction industry evolving, adapting, and embracing technology to bring real-time information into processes that are hundreds of years old. These advances make our jobs easier every day.”

The Final Result: IoT Sensors Help Companies Avoid Insurance Claims & Rework

Overall, JSITM helped the Stantec project team increase quality, productivity and safety on the project, reduce energy usage and costs, reduced rework and warranty claims, and shorten the projects schedules.

With optimized heating thanks to JSI™, over the winter of 2018 the project reduced gas heater usage by 46% saving approximately $180,000 while also reducing electric heater usage by 58% saving around $69,000 in power bills.

In addition to efficiency gains, JSI™’s real-time alerts saved more than $170,000 in conservatively projected rework costs due to potential millwork damage caused by adverse temperature and humidity conditions that are present on all job sites. In one event, the project team was alerted to a temperature spike in a residential unit.

With real-time monitoring and alerts, regular in-person monitoring was not required, saving the team untold hours in manual labour. Teams held a regular JSI™ debrief each morning before getting on with building Stantec Tower.
