Anyone on a lump sum design contract knows the week the review comments land: hundreds of rows, team already behind. Some are real mistakes, some are questions, some were never in scope. Sort them first, or every row gets fixed for free.
One case on our Try page: the City's and ODOT's comments on a road design, lump sum fee. Yesper sorted them by what the fee covers, hours on each. 11 were new requirements outside the scope and carried 37% of the resolution hours: an additional services request. Another set cited criteria the owner had already replaced.
New requirements go to the owner before the hours are spent, and comments built on superseded criteria go back as a question instead of unpaid work. Same for any review round, and the rest of the Try page: a review protocol for a design package, the revisions in a drawing set.
