Ahern celebrated the ribbon-cutting of our new Mason City, Iowa, office last week in partnership with the Greater Mason City Chamber of Commerce.

This new location strengthens our presence in Iowa and expands our ability to serve customers throughout northern Iowa with responsive, local fire protection and life safety expertise. From fire sprinkler systems and special hazard suppression to fire alarm systems, inspections, maintenance, and repair, our Mason City team is ready to support commercial and industrial customers across the region.

Thank you to the Mason City Chamber of Commerce and everyone who joined us to mark this exciting milestone. We look forward to building strong relationships in the Mason City community and continuing to help protect people, property, and businesses across northern Iowa.

Predictability is the new competitive advantage in industrial construction.

Our latest blog explores how modular prefabrication helps facility managers reduce field unknowns, shorten shutdown windows, improve quality control, and lower total installed cost by shifting critical fabrication work into a controlled shop environment.

From pipe and plumbing fabrication to sheet metal, industrial, and fire protection systems, JF Ahern’s prefab capabilities are built to help projects move faster, safer, and with fewer surprises.

Learn how modular prefabrication is reducing downtime in industrial facilities in comparison to traditional field fabrication. JF Ahern offers many prefab services.

At Ahern, excellence is more than the quality of the finished product. It is found in how we work, how we collaborate, and how we remain accountable to safety, our customers, and one another.

What's On Your Mind Matters.

At Ahern, safety is the most important thing we do — and that includes supporting the mental well-being of our people.

As we wrap up Mental Health Awareness Month, we’re highlighting the ongoing work behind Ahern Mind Matters, our mental health initiative designed to connect employees and their families with helpful resources, support, and information.

This effort is guided by our dedicated mental health committee, which helps keep mental health at the forefront of our safety culture through employee resources, team discussions, training, and continued awareness. But it’s our people who truly put this into practice by showing up for one another and making it part of how they work every day.

Because creating a safe workplace means more than protecting people physically. It means building a culture where our people feel supported, valued, and empowered to ask for help when they need it.

Congratulations to Ahern apprentices Sawyer Nelson and Trevor Roehrig on earning first place at their respective state apprentice competitions!

Sawyer, a Sprinkler Fitter apprentice with our Twin Cities Service team, took the top spot at the 2026 Minnesota Pipe Trades Association State Apprentice Contest. Trevor, a fifth-year Steamfitter apprentice with UA Local 400, earned first place in the Wisconsin Steamfitter Competition.

Both competitions tested apprentices on technical skill, craftsmanship, safety, and industry knowledge — and Sawyer and Trevor rose to the top.

Next up, they’ll represent their locals and Ahern at the UA District Competition in Chicago, June 9-11, competing against top apprentices from across the region.

Their accomplishments reflect the strength of Ahern’s apprenticeship programs and the dedication, mentorship, and hands-on learning that help our people succeed.

Please join us in congratulating Sawyer and Trevor and wishing them the best of luck in Chicago!

Veterans bring discipline, adaptability, and a deep commitment to the mission; qualities that continue to make an impact across Ahern every day.

Our Veteran Spotlight series continues as we recognize the veterans who help drive our work forward, on jobsites, in the office, and across the communities we serve.

Second spotlight: Dan Eckert, NE Mechanical Service Superintendent.

Dan’s story is a powerful example of how military service builds the mindset to lead under pressure, support others, and stay focused on the mission at hand.

Check out his story in the video and follow along as we continue recognizing the people behind the projects who make Ahern stronger.
