Winter construction in Calgary poses challenges like freezing temperatures, heavy snowfall, schedule delays, increased costs, and safety risks. However, with proper strategies and preparation, projects can proceed smoothly and safely.
Here, we’ll explore common challenges and share proven solutions used by seasoned builders to keep Calgary’s winter construction projects on track.
Common Winter Challenges
1. Temperature Drops
During Calgary's winter months, temperatures can plunge far below zero, posing risks to materials and machinery alike.
Impact on materials and machinery: Cold weather can hinder the curing process of concrete, leading to reduced material strength. Similarly, machinery may struggle to function efficiently, with cold temperatures affecting engines, hydraulic systems, and fuel lines. To mitigate these issues, consider using winter-specific additives for concrete and maintaining equipment in heated areas whenever possible.
2. Snow and Ice
Snow and ice are among the most visible winter challenges, impacting both access and safety on construction sites.
Site access and safety hazards: Snow accumulation can block pathways, while ice increases the risk of slips and falls. To combat this, designate teams for regular snow removal and use salt or sand to improve traction around the site. Employing winter-specific safety protocols can significantly reduce accidents and ensure site accessibility throughout the season.
3. Limited Daylight
Winter days are short, which can reduce the amount of time available for construction work.
Reduced working hours and productivity: Fewer daylight hours mean teams need to be strategic in scheduling critical tasks. Invest in high-quality lighting for darker areas and consider adjusting work shifts to maximize daylight utilization for outdoor work, saving indoor tasks for the darker hours.
4. Materials Handling
Handling materials like concrete and asphalt in winter requires specific adjustments to ensure quality.
Concrete Application: Cold weather slows down the curing process, potentially weakening the concrete. To prevent this, use heaters or blankets to keep concrete warm as it cures.
Asphalt Work: For asphalt, timing is critical. Plan asphalt applications for warmer periods of the day to ensure it adheres and cures correctly, preventing costly rework.
Technology and Equipment Solutions
1. Heated Tents and Enclosures
Creating heated workspaces allows projects to continue even in the harshest weather.
Benefits for ongoing projects: Heated tents provide a controlled environment, keeping workers warm and materials at optimal temperatures. This setup also allows for uninterrupted work, helping projects stay on schedule despite Calgary’s freezing winter conditions.
2. Winter-Specific Machinery
Equipping your site with machinery designed for cold conditions can minimize downtime and increase safety.
Examples and uses: Machinery with features like heated engines, snowplows, and de-icing capabilities can handle snow and ice efficiently. Investing in winterized equipment can save time and reduce maintenance issues, helping the project stay on track.
Safety Measures
1. Enhanced Gear and Clothing
Winter work requires specialized clothing and gear to ensure the safety and well-being of workers.
Importance of proper attire: Providing workers with insulated, weather-resistant gear protects them from frostbite and hypothermia. Proper winter safety gear keeps teams comfortable and focused, boosting morale and productivity.
2. Site Maintenance
Maintaining a safe, accessible workspace is critical in winter.
Snow removal and surface treatments: Regular snow removal and applying traction enhancers like sand or salt keep the site safe and accessible. These practices prevent slips, falls, and other accidents, ensuring smooth and safe operations on-site.
Legal and Compliance Aspects
1. Building Codes
Construction in winter comes with specific regulations to ensure safety and compliance.
Winter-related requirements: Understanding local building codes, such as those concerning frost protection and insulation, is essential. Adhering to these standards not only ensures legal compliance but also enhances the structural integrity of the build.
2. Work Hour Regulations
In colder months, adjusting working hours is necessary to keep workers safe.
Adjustments for worker safety: Regulations often require fewer working hours in winter for worker safety. Planning shifts accordingly reduces the risk of accidents and ensures team well-being during these challenging months.
Planning and Schedule Adjustments
1. Advance Preparation
Winter construction requires thorough planning to anticipate and mitigate issues that may arise.
Importance of preseason planning: By scheduling critical tasks and ordering materials ahead, you minimize project disruptions. Establishing a clear winter action
plan keeps teams ready for Calgary’s winter conditions, helping avoid delays.
2. Flexibility
Having flexibility built into project schedules allows teams to adapt to unforeseen delays or issues.
Managing delays: Creating contingency plans and buffer periods within the schedule allows for flexibility if weather impacts the timeline. This way, projects can maintain momentum, even when faced with unexpected weather conditions.
A general Case Study Successful Winter Project
The Calgary City Centre project is a prime example of successful winter construction.
Project description and outcomes: By using heated enclosures and winter-specific machinery, the team overcame Calgary’s snow and cold. These tools allowed the project to be completed on time, showcasing the effectiveness of planning and innovative solutions.
Conclusion
Calgary’s winter presents construction challenges that require preparation, technology, and a focus on safety. By leveraging winter-specific solutions, embracing safety protocols, and planning proactively, construction teams can successfully overcome these obstacles. With careful planning and adaptation, winter construction in Calgary is not only possible but can be executed efficiently.
