What Our Clients Say
“ACBS is our first choice for steel drafting services. In addition to prompt quotes and schedule potentials, they are knowledgeable of all types of structures, both new & rehab, and are very aware of various Owner/DOT’s expectations for submittals. The best part of ACBS is that they require no “hand holding” on our projects, I can send them instructions and be confident it will meet expectations.”

The accuracy of his work has been excellent, and with today’s fast-track scheduling being the norm, Ilko has always exceeded all of our expectations for fast completion of shop drawings. Service is number one in any business, and Ilko has always exceeded in taking care of all of our detailing and NC programming needs.”

“We were overwhelmed by the speed with which you accomplished the detailing. As a result, we will make our delivery on or ahead of schedule. Your accuracy was superb. I can tell by the number of shop calls I receive during a project as to how well the drawings were prepared. The 3-D helped us tremendously, and I’m aware of no deficiencies in your work. We very much look forward to our next job with you. Thank you so much for your effort.”

“I used ACBS to create manufacturing drawings and details for a novel floating wind turbine that I invented with a colleague. The configuration involved many novel elements and I was grateful for Ilko’s original thinking and experienced guidance. In addition, Ilko’s work was fast and accurate. I look forward to working with Ilko again.”
