For almost 90 years, Hensel Phelps has built across the United States, delivering aviation, infrastructure, healthcare, commercial projects and more, despite the weather. For construction teams working outdoors, extreme heat can be part of their daily jobsite environment. Those conditions require careful planning as project teams work to send every employee and trade partner home safely.

In April 2026, the Occupational Safety and Health Administration (OSHA) renewed its National Emphasis Program for outdoor and indoor heat-related hazards, including construction. The agency notes that physical work in high temperatures, along with heavy or bulky clothing and equipment can lead to increased heat-related risk. That work is especially relevant in Arizona, where Diverge, a Hensel Phelps company, is exploring whether emerging wearable technology could be another tool for teams.

Exploring Eztia’s HydraVolt™ Technology

Diverge is collaborating with Eztia, a San-Francisco-based tech startup developing cooling materials for those working in hot environments. The technology responds as body temperature rises by drawing heat away from the skin and dispersing it through the fabric.

Eztia’s HydraVolt™ technology incorporates a proprietary cooling gel directly into performance fabric. The company reports that HydraVolt™ can reduce skin surface temperature by up to 10 degrees Celsius and provide up to eight hours of cooling during strenuous physical activity. Additionally, the technology does not require batteries or electricity and can be reactivated with water.

Wearable cooling technology does not replace established heat-illness prevention practices, but it could serve as an additional layer of support for employees. Evaluating solutions like HydraVolt™ can also help teams better understand where emerging technologies may have a practical role in jobsite safety.

Evaluating Performance Beyond the First Test

Diverge’s role is to understand how solutions like this perform outside the lab and in conditions that more closely reflect the realities of construction work. Kyle Tomak, Diverge senior innovation manager, first tested the HydraVolt™ material while landscaping outdoors over a 114-degree weekend in Phoenix, Arizona. Impressed by how long the fabric remained cool, Tomak then distributed the solution to Hensel Phelps safety directors nation-wide for project team testing and feedback.

This round of evaluation focuses on how the solution performs under the demands and conditions of day-to-day field work. Early feedback has been encouraging, while also highlighting practical considerations for extended use. After several hours, the material needed to be reactivated with water, an important factor when evaluating how wearable cooling technology could fit into a full construction workday.

For wearable cooling technology, that means considering questions such as:

• How long does the cooling effect last under different working conditions?
• How easily can the material be reactivated during the workday?
• Is it comfortable enough for extended use?
• How does it hold up under repeated wear?
• Is it compatible with existing personal protective equipment?
• Does its performance remain consistent across different environments and types of work?

Materials integrated into everyday workwear may eventually offer another way to help construction workers manage environmental conditions in the field. The Diverge team will continue collaborating with Eztia to test it’s HydraVolt™ material across real-world conditions and better understand its durability, usability and potential applications.

What Wearable Cooling Could Mean for Construction Safety

Hensel Phelps teams working in regions where triple-digit temperatures are a regular part of the construction environment, continuing to explore those questions matters. Through Diverge, Hensel Phelps can evaluate new approaches with the people who may ultimately use them, keeping innovation connected to practical application and focused on helping teams work safer, efficiently and more effectively.

Addressing Challenges

Led by the Rocky Mountain Region Virtual Design and Construction (VDC) team with support from Diverge, a Hensel Phelps company, the initiative pilots Unreal Engine, a real-time 3D development platform, to create interactive environments that help project teams better understand existing conditions before construction begins.

Key Takeaways

Addressing Aging Infrastructure: Municipal water and wastewater systems present significant challenges due to deteriorating underground infrastructure, incomplete utility records and the need to maintain uninterrupted operations during rehabilitation.

Immersive Project Visualization: By combining Building Information Modeling (BIM), LiDAR reality capture scans and Unreal Engine, project teams can explore facilities in a fully interactive environment, improving communication, constructability reviews and decision-making before work reaches the field.

Improved Coordination: The technology helps owners, designers and builders identify potential conflicts early, evaluate construction sequencing and better understand how new systems will integrate with existing infrastructure.

Real-World Application: At the Windsor Wastewater Treatment Facility, Hensel Phelps overlaid LiDAR scans with BIM models to gain a more accurate understanding of constrained underground conditions, strengthening coordination and reducing uncertainty before construction.

Supporting Existing VDC Workflows: Rather than replacing current VDC tools, Unreal Engine enhances established capabilities such as constructability reviews, 4D planning, digital coordination and owner engagement through more immersive visualization experiences.

Why It Matters

The pilot demonstrates how gaming technology can be adapted for construction planning, allowing project teams to make more informed decisions, reduce project risk and improve collaboration on highly constrained water infrastructure projects. As investment in resilient water and wastewater systems continues to grow, Hensel Phelps is evaluating immersive visualization as another tool to support safer, more coordinated and efficient project delivery.

Hensel Phelps is accelerating the use of robotics in construction through a structured, deliberate approach led by its innovative arm, Diverge. The company collaborates with technology leaders such as Hewlett-Packard (HP) and Hilti, Inc. to evaluate and pilot new automation tools. These trials include deploying HP SitePrint, a layout robot, which demonstrably halved layout time while achieving 100 percent accuracy on one Arizona project. Diverge also evaluated Hilti’s Jaibot for autonomous drilling tasks. In each case, the program managed controlled testing protocols, gathered onsite feedback and facilitated seamless integration into operations

Looking ahead, Diverge plans to extend this methodology across multiple projects and robotics applications. Mihir Somalwar, an Innovation Lead at Diverge, notes that growth in artificial intelligence (AI) technologies marks 2024 as a milestone year for robotics in construction. By combining systematic pilots with strategic collaboration and data‑driven insights, Hensel Phelps is pioneering a safer, more efficient and sustainable future for the construction industry.
