Tessiers Successfully Installed 22 RTU Units with a Helicopter!

Recently, our Tessiers team was tasked with the safe and efficient installation of 22 RTU units, weighing between 650 and 2500 pounds, on a 330,000 square warehouse, located in Sioux Falls, SD. Our initial obstacles were identified: 150-foot reach from the building’s edge, and units spanning roughly 450 feet east to west and 250 feet north to south, and 42-foot-high walls.

Typically, such installations would involve the use of a crane. However, our experienced preconstruction team determined that using a rotorcraft would be more effective.

Safety was our top priority. Working alongside one another, the Operations Manager, Safety Director, Foreman, and Project Manager noted that the parapet wall was less than 42 inches and identified rooftop openings with drops exceeding 6 feet. To avoid potential falls and safely navigate across the rooftop we determined the best application for this task would be using two mobile fall protection devices (raptor carts).

Our foreman Robert Burns, noticed each cart would require a team of four, North Team and South two members to move the cart and two to place each unit and disassemble the rigging. The roof top navigation plan was put on paper.

The night prior to the pick, a plan pre-task session was conducted by Tessiers with the GC, and all operation leaders. Tessiers ensured our safety plan would be enforced, and the job site was prepped, and all hazards have been addressed. We discussed procedures and identified additional hazards. The signalers played crucial roles in directing the helicopter and providing communication with the pilot and our team members.

Having identified potential hazards and implemented safety measures, we proceeded with the pick plan early the next morning. Tessiers took control

of the job site, blocking access to the building, setting up extraction points, distributing personal protective equipment (PPE), and staging the units. A final review of the pick plan was conducted with the collective staff.

As an audience gathered outside the protected zone, our plan was implemented. Our rooftop team efficiently moved across the building while the ground team prepared for the next pick. Each member was vital to ensure the operation was completed seamlessly. We were able to set each unit in under three minutes.

Addressing all aspects of safety, communication and preplanning by our team made this task a success.

Welding is more than just fusing pieces of metal together; it’s about precision, safety, and expertise. In commercial and industrial applications, choosing a welder with the right skills and certifications is crucial to ensuring the quality and longevity of a project. Specialty welding certifications and skills are indicators of a welder’s expertise and ability to meet rigorous industry standards. In this post, we’ll explore some common types of specialty welding certifications and capabilities, giving you insight into what sets top-notch welders apart.

Specialty Welding Certifications

1. AWS Certified Welders

One of the most recognized certifications in the welding industry is the American Welding Society (AWS) certification. AWS-certified welders have passed tests that demonstrate their skills in various welding processes, including MIG (Metal Inert Gas), TIG (Tungsten Inert Gas), and stick welding. This certification ensures that the welder meets industry standards for quality and safety, making them a reliable choice for complex projects.

Whether it’s a structural steel project or intricate metalwork, having an AWS certification guarantees the welder is knowledgeable about the latest techniques and able to produce consistent, high-quality results.

2. GMAW, SMAW & FCAW Certified Welders

Three commonly used welding techniques are GMAW, SMAW, and FCAW, and specialized welding certifications are often required for each:

• GMAW (Gas Metal Arc Welding): Also known as MIG welding, this process uses a continuously fed wire to create a strong, consistent weld. It’s widely used in industries requiring speed and precision, such as automotive and manufacturing.
• SMAW (Shielded Metal Arc Welding): Known as stick welding, this traditional method is valued for its simplicity and versatility. It’s often used in construction and repair work, especially in outdoor or confined spaces where portability is essential.
• FCAW (Flux-Cored Arc Welding): Similar to GMAW, FCAW uses a flux-filled electrode, making it ideal for welding thicker materials or in challenging outdoor environments where wind might be an issue.

Having certifications in these techniques indicates that the welder can handle a range of materials and projects with specialized needs.

3. OSHA 10 & OSHA 30 Certified Staff

Safety is a top priority in any industrial setting, and certifications like OSHA 10 and OSHA 30 are crucial for ensuring job site safety. OSHA (Occupational Safety and Health Administration) certifications involve training programs that educate workers about identifying hazards, preventing accidents, and maintaining safe work practices.

• OSHA 10: A 10-hour training program focused on the basics of workplace safety, suitable for entry-level workers.
• OSHA 30: A more comprehensive 30-hour program aimed at supervisors and workers with safety responsibilities, covering a broader range of hazards and safety procedures.

Welders with these certifications are not only skilled in their craft but also well-versed in maintaining a safe working environment.

Welding Specialties and Capabilities

1. Confined Space Welders

Working in confined spaces presents unique challenges, from limited visibility to restricted movement. Confined space welders are trained to handle these environments safely and effectively. They undergo specialized training to manage the hazards associated with small or enclosed spaces, ensuring that they can work on projects in tanks, vessels, or tight structural spaces without compromising safety.

2. On-Site Welding Services

For many projects, on-site welding services are a necessity. Having a team of welders who can travel to your location and perform the necessary work can save time and costs associated with transporting materials. On-site welders are adaptable, capable of handling a variety of conditions, and prepared to address unexpected challenges that might arise during installation or repair.

3. Pulse Welding

Pulse welding is an advanced technique used to control the heat input during welding. By pulsing the current on and off, welders can produce cleaner, stronger welds with less spatter and distortion. This method is ideal for thin materials, aluminum, and other metals that are prone to warping or cracking. Welders skilled in pulse welding are highly sought after for projects requiring precision and a clean finish.

4. Structural Welding

Structural welding involves the fabrication and repair of structures like bridges, buildings, and heavy equipment. It requires a deep understanding of load-bearing capacities, material properties, and construction standards. Structural welders must adhere to strict guidelines to ensure the safety and stability of the structures they work on. Certifications in structural welding ensure that the welder is competent in handling large-scale projects that demand both expertise and accountability.

Why Certifications and Specialties Matter

Hiring a certified and specialized welder can make a significant difference in the success of a project. Certification ensures that the welder has met industry standards and possesses the technical skills required for the job. Specialties, such as confined space welding or pulse welding, add another layer of expertise, demonstrating the welder’s ability to handle complex or unusual projects.

For property managers, industrial facilities, or anyone responsible for overseeing construction and repair projects, understanding these certifications and specialties can guide you in selecting the right professionals for the job. Choosing a certified welder means investing in safety, quality, and long-term value.

Choose the Right Certified Welders 

Welding certifications and specialties are more than just credentials—they’re a testament to a welder’s dedication to quality, safety, and excellence. From AWS and OSHA certifications to specialized skills like pulse welding and structural welding, these qualifications ensure that welders can meet the demands of any project. Whether you’re in need of on-site services or a quick turnaround on a custom order, partnering with certified professionals guarantees that your project will be handled with the utmost care and expertise.

As a commercial property manager, you know how important it is to keep tenants and guests comfortable. Balancing heating and cooling can be tricky, especially with varying needs across different areas of a building. Factors like the number of occupants, heat from equipment, and insulation levels all affect how your HVAC system performs. It’s not just about setting a temperature; it’s about managing different needs and ensuring consistent comfort throughout the building. Efficient climate control is crucial for maintaining satisfaction and attracting tenants, making it essential to address these challenges effectively.

HVAC system zoning can help by dividing your building into different areas, each with temperature controls. This allows for more precise climate management, improves comfort, and can even reduce energy costs. For instance, the upper floors of an office building might need cooling while the lower floors stay warmer, and a computer lab may require extra cooling. Zoning helps ensure each area gets the exact temperature it needs.

How HVAC System Zoning Works

An HVAC zone control system uses thermostats, a central control panel, and zone dampers installed in the ductwork. Each zone has a thermostat that communicates with the control panel, which adjusts the dampers to regulate airflow. This setup allows each zone to control heating and cooling independently without affecting others. 

Commercial HVAC companies insert dampers into the ductwork to enable HVAC system zoning. These dampers isolate various parts of the building so that conditioned air cannot enter them. A satellite thermostat is included in each zone to adjust the local temperature without affecting the temperature elsewhere. 

For example, a zone with many computers requiring extra cooling will not influence the temperature in adjacent zones. This system is efficient, especially in buildings with varying temperature needs, as it targets only the areas in use, optimizing comfort and reducing energy consumption.

 Elements for HVAC System Zoning 

• Zone Dampers: Installed in the ductwork, these dampers open or close to direct airflow to specific zones, enhancing energy efficiency and temperature control.
• Thermostats: Each zone has a separate thermostat to monitor temperature and send data to the control panel, which adjusts the dampers and HVAC equipment accordingly.
• Control Panel: This is the system’s central unit, processing thermostat data to manage dampers and equipment, often with digital interfaces for setting preferences and schedules.
• Ductwork Modifications: Installing zoning may require changes to the ductwork, including additional dampers and bypass ducts for balanced airflow.
• Damper Actuators: These mechanisms control the dampers based on signals from the control panel, enabling precise temperature regulation.

Benefits of HVAC System Zoning

The benefits of a well-designed HVAC zoning system include focused, consistent heating and cooling, customized temperature control for better employee comfort, and significant energy and cost savings. Adjusting heating and cooling based on each zone’s specific needs can reduce energy waste and potentially lower costs by up to 25 percent.

• Energy Efficiency: HVAC System zoning allows you to heat or cool only the areas that need it, reducing energy consumption and lowering utility bills, especially in rooms that are not frequently used.
• Longer Equipment Lifespan: By preventing your HVAC system from working harder than necessary, zoning reduces wear and tear on the equipment, extending its life.
• Reduced Temperature Swings: Zoning eliminates large temperature fluctuations when a single system tries to balance multiple needs simultaneously.
• Targeted Temperatures: Zoning enables precise temperature control for different areas, such as providing extra cooling for heat-generating equipment without affecting other parts of the building.
• Increased Comfort: Personalized climate control means everyone can enjoy their preferred temperature, enhancing overall comfort.
• Improved Property Values: Modern zoning systems add appeal to your property, making it more attractive to potential buyers or tenants due to the enhanced comfort and energy efficiency they offer.

Considerations When Planning a Commercial Zoning System

Careful planning and design are essential to maximizing the benefits of a commercial HVAC zoning system. Keep individual zones manageable—ideally, no larger than a single floor or a few rooms. Zoning systems are less effective in open spaces or areas with frequent temperature changes, like warehouses or spaces with open doors. Place thermostats in each zone’s most frequently used room to ensure accurate temperature control. Group rooms with similar energy efficiency features and thermal characteristics within the same zone for optimal HVAC performance.

While a zoning system offers many benefits, there are some potential drawbacks. One is the higher initial cost of installation compared to traditional HVAC systems. Setting up an HVAC zoning system can also be more complex, often requiring professional expertise and additional installation steps. Regular upkeep is important to address any issues that may arise, and it’s best to work with experienced technicians to keep the system running smoothly.

Adding HVAC System Zoning To An Existing System

Before considering HVAC system zoning, evaluate your existing system’s readiness. Ensure your HVAC equipment is modern and robust enough to handle zoning, and check if your ductwork can accommodate it with minimal modifications. An HVAC specialist can evaluate your setup and recommend a suitable zoning plan based on your building’s layout, sun exposure, and usage. Installation typically involves adding zone dampers to direct airflow, equipping each zone with a thermostat, upgrading the central control panel, and fine-tuning the system to ensure proper operation.

For property managers, weighing the investment against potential returns is essential. While zoning can improve energy efficiency and tenant satisfaction, it also involves initial costs and possible disruptions. Plan for downtime during installation and be prepared for increased maintenance needs due to the added complexity. Working closely with HVAC professionals will help ensure that HVAC system zoning enhances your system’s performance and aligns with your property’s needs.

Enhance Your Building With HVAC System Zoning 

HVAC zoning enhances comfort, energy efficiency, and cost savings by allowing tailored temperature control in different areas. Although it involves a higher initial investment and added complexity, the benefits can be significant depending on your property’s needs and layout.

According to the U.S. Fire Administration, “each year in the United States, an average of 2,300 air conditioning fires occur in residential structures. These fires are responsible for approximately 60 civilian injuries, less than 5 civilian deaths, and $23.8 million in property loss.”

 Causes of AC Unit Fires

• Flammable Materials 
• Dirty HVAC Unit 
• Insufficient Lubrication 
• Broken Parts 
• Faulty Wiring 

Portable AC Unit Fires 

The U.S. Fire Administration reports that 35% of installed AC units are either portable or fixed local units, yet these account for 55% of all AC unit fires. This statistic underscores a significant safety concern associated with these types of units. While they offer convenience and flexibility, their higher incidence of fires raises questions about their design, installation, and maintenance.

Preventing AC Unit Fires

HVAC fires pose serious risks, but preventive measures can safeguard your tenants and property. Professional installation, whether for portable, fixed, or central units, is very important, especially in hot climates and during hot weather when AC units are under increased strain. 

Avoid using extension cords and ensure proper cord placement to prevent overheating and contact with flammable materials. Avoid placing cords under carpets or allowing debris to accumulate, as overheating can lead to ignition. Ensuring clean filters, functional thermostats, and up-to-date electrical components is critical.

Regular Maintenance Of HVAC Systems For Fire Safety

Regular preventative maintenance of HVAC equipment is the first step in managing the risk of HVAC fires in any building. To prolong the lifespan of your unit, HVAC professionals will make sure that the ducts and filters are clean and will solve problems as soon as they arise. Setting aside time for biannual unit maintenance can help your unit last longer and keep your family and house safe.

 Integration of HVAC and Fire Protection Systems

 Proper alignment of fire alarms and HVAC systems is crucial for occupant safety and operational efficiency, significantly impacting life and property protection during emergencies. Integrating them offers several benefits:

• Enhanced Safety: Automated shutdown of HVAC systems when the fire alarm is activated prevents smoke and fire spread, safeguarding occupants.
• Improved Energy Efficiency: In the absence of fire alarm activation, HVAC systems adjust settings to conserve energy.
• Simplified Maintenance: Integration streamlines maintenance by combining fire alarm and HVAC systems, enhancing overall system efficiency and reliability.

Fire dampers, wraps, and stopping are vital for HVAC fire protection, enhancing building resilience against fires. Dampers automatically close to contain fire and smoke in ducts, while wraps delay heat penetration. Fire stopping seals gaps, preventing fire spread. Integration with alarms and sprinklers ensures efficient evacuation. Incorporating fire-resistant materials in HVAC design strengthens building safety.

How to Integrate Fire Alarm and HVAC Systems

Whether you’re building a new property or updating an existing building, integrating fire alarms with HVAC systems is a key step for safety. Landlords should work closely with engineers and contractors to ensure a safe and effective set up that complies with local and national codes.
