Successful construction begins with solid foundations.

Irby Construction puts large pier-drilling foundations in place as well as any type of slab foundation needed to support towers erected during transmission construction projects.

Experience has prepared our crews to effectively conduct slurry drilling, rock drilling, and casing holes. The various pier formation types we put in place support single piers, H-Frames, 3-pole structures, and four-legged towers.

We are thorough in obtaining mix designs and submittals imperative to the job before work begins. Then, we bring astute attention to the details of the specifications provided by owners and/or engineers, to ensure the project is completed properly according to standards. Where applicable, strategic partnerships allow us to refine and optimize foundation designs by fully integrating engineering and construction.

Of course, specific procedures guide all our fieldwork ensuring the safety of our team. This is our top priority in everything we do.
