An integral part of the comm building process is checking the skew. After all the bars and mica are stood up into a segment pack we check the skew to ensure the bars are straight and not leaning to either side. It's a tedious process and takes a trained eye and patients to look at each and every bar individually. It's a step that can not be skipped because if a bar is out of skew it will cause major problems throughout the process and the comm would then need to be rebuild from the beginning.
