You could start by saying the name of the quest, but normally if it is a note, or something like that, you need to read it to update the quest.
edit, sorry you did say quest is steal the plans.
if you are in computer you can use the console to force the quest into updating http://www.uesp.net/wiki/Skyrim:Stealing_Plans
