Tilt-Up Design Systems, LLC has released a free web-based tool for quick preliminary panel thickness and reinforcing estimates. The tool works by simply entering the panel width, height, thickness, design wind speed/exposure and opening width for your project. An estimate of the reinforcing steel required will be provided measured in pounds per square-foot based on the gross panel area. The tool was developed using Tilt-Werks® technology.
