Where Irby is at Work

At any given time, Irby crews are on the job at various sites across the country. The map above shows the concentration of our work by location and year. The color scale on the map above gets “warmer” from left to right to indicate where more projects are in progress. This includes electric power transmission, distribution, and substation projects of various scope and size. Irby partners with select clients on a service contract basis and others on a per-project basis to build and maintain electric power infrastructure.
