Johnson Brothers Corporation Uses Robotic Total Stations for More Accurate Construction on Downtown Birmingham Bridge
In determining the best survey-grade instruments needed for setting the columns, erecting the shoring towers and falsework, and for accurately placing each segment (as well as for the casting yard work described above), JBC turned to Earl Dudley & Associates, a Birmingham-based firm with an 80-year history supplying survey instruments to the region. Having worked with them in the past, Anderson was confident that they would understand their needs and give them the support a project of this size demanded.
“I've had a relationship with the Dudley company since we were on a job together in 2006,” he said. “The fact that I knew them, felt comfortable with them and they were right here in town was huge for us in making our decision. Because of the tight time frame, we couldn't afford to have to go to Atlanta or elsewhere to get a calibration or a fix if something went wrong. Now, if a guy breaks a bipod in the morning, we know we'll have a replacement that afternoon.”
That vote of confidence, said Brian Singleton, Dudley's Sales Representative, is the result of a concerted effort on their part to make it happen. ”We always try to look at our relationship with the customer as a partnership,” he said. “If they have a problem and we can't make it right, it hurts us both. So, we've been working with them from very early on, helping them integrate the use of survey gear at the precast plant, and everything moving forward. That's just the way we do things.”
