Release Notes;

Significant effort has been made to do the calculations in a manner that is consistent with the engineering references cited throughout the 'calculator' and to do so without logic or arithmetic errors. The new program release is intended to capture and reflect updates within the engineering principals and practices for North America. Although every effort has been taken to ensure the accuracy of the program, variables and or unknowns may effect final results. Due to this, users retain the responsibility for the correctness and accuracy of tool results. If any errors are encountered, and or improvements are identified, please send this information to so that this tool can be further validated for accuracy and improved as needed.
