“The efficiency of the robot was awesome! It was definitely a big help to our schedule.”

Owner, Steel Enforcers

TyBot recently completed its first project for rebar subcontractor Steel Enforcers, Inc. on Collins Creek Bridge in Mobile County, AL. This 37,000 square foot bridge deck had a 50% tie requirement for both top and bottom mats. Extreme weather conditions interrupted rebar installation multiple times, making schedule an even higher priority than usual. TyBot was glad to help. Thank you, Steel Enforcers!
