Take Home a Piece of Our History
2021 marked the 75th anniversary of Irby Construction. This major milestone was achieved thanks to all the people of Irby – those who came before and those who are currently employed at Irby. To honor this milestone and celebrate the accomplishment, Irby published 75 Years of Powerful Connections, a commemorative coffee table book to share our stories and remember our history.
