We started as pioneers in our industry and that spirit prevails at Irby today.
Our company built the electric grid we’re expanding and upgrading today. We created construction processes that have been adopted as industry standards. And we continue to push boundaries.
This company has built electric power infrastructure all over the United States and abroad. From Alaska to Africa – we became known for our ability to tackle the biggest challenges and develop solutions.
STRONG AT 75
At 75 years old, this company’s experience is storied, and our track record is solid.
Today we are standing on the solid foundation our history provides. But we refuse to rest. It’s not in this company’s DNA.
We’re growing like never before. We’re expanding our scope of services. We’re employing new technology. And we’re continuously raising the bar for safety, training, and productivity.
Our industry will continue to change but one thing will always stay the same. Irby’s approach to absolute performance and our family-first culture is forever here. It’s what shapes the experience of working with our team. Count on it.
