You may not need to contact the engineer if the numbers are close.Recheck the other numbers to see how close you are to discover errors.Adding the delta and the curve will help resolve calculation issues.Enter the PC, PI, and PT coordinates and stations first.The following is a list of troubleshooting tips: It’s probably a typing error and a clue there is a problem ahead. Notice in this example the PI has two (2) different coordinates. When things aren’t working with the parameters entered, you will need to decide what figures to pursue and leave the rest to tweak as you go. The coordinate geometry (COGO) of a road, or construction centerline, can either be a quick data entry job or an enduring nightmare. ![]() If you are a beginner, we will offer resources to get you up to speed. These will be high level overviews of the enhancements we use for basic road elements. In upcoming blog posts, I will go over the different approaches available for both Trimble Business Center and Carlson. My advice is to think differently about the approach. It takes years of experience to fully understand the process. There is nothing more difficult, or rewarding, than seeing a highway job perform well from dirt work to paving. ![]()
