Compare the issues of a tender document
Add the original issue and up to four corrigenda, in order. Every change is marked on the page in the colour of the issue that made it, with a list of changes by clause.
How to read this (the same code as our tender documents): added words are green; removed words are maroon, italic and struck through (on the page, a maroon marker shows where they were; hover or tap it, or turn on side by side). The bar in the margin is amber for a changed line, green for an added one and maroon for a removed one, and the tag beside it names the issue: Corr.1 Corr.2 Corr.3 Corr.4. Line breaks, spacing and hyphens are ignored. Lines repeated at the top or bottom of most pages (headers, footers, page numbers) are compared separately and any change to them is listed once, as is any change repeated on several pages; changes that only alter a clause number are listed together. Scanned pages without a text layer cannot be compared here. The page view needs PDF files; Word and text files get the changes list. This is a word comparison only; the full service adds the clause risk register and checked notes.
