The DP drawings a city sees are often not detailed enough to be commenting on the presence of precast or CIP concrete, in fact if done properly pored concrete can be of similar quality to precast. A UDP is what the city would be creating to comment on the quality of the proposals brought before the city, however once again they are primarily concerned with the overall aesthetic of the building and not the precise materials spec'd. There is a UDP system set up on Vancouver and some of the shit that passes here is quite bland imo, you can only push a developer so far before a project becomes unprofitable.
