Line-by-Line definition
Line-by-Line check means the Checker will work from a copy of the Designer’s calculations, going through line-by-line and redlining. Besides checking line by line, the Checker must also ask “Has the Designer included all calculations required?” Generally there is a time savings in performing this type of check. Other benefits of this type of checking include: calculation book is complete (for design purposes) at PS&E, junior designers can see senior designers work, and content is complete and understandable (especially worthwhile if revisions are required during construction).
