You are lucky that I've just finished last few things with my ConstructEvent.
Btw GetTriggerUnit() returns unit which construction has begun, instead of actual builder unit. Worry not, after short lecture, link below will sent you to place where pesky construction events are polite and teddy.
When talking about unit construction, you have to consider multiple factors:
-race of structure unit
-item usage
-item-based build ability
-collision/pathing (space taken by building)
-if structure-unit is organic or mechanic type of unit
In case you don't know, buildings can be build on "arbitrary" coordinates (like doodads) and then issue complicates even more.
Common trick is to check builder's coords and structure coords on construct start event. Are we fine? No, when structure has no collision radius, there might be difference between those values.
What more, those values have to be translated accordingly to map's quarter (XY axis). Oddly enough, those coordinates will be rounded up or down to 0.250 base depending on quarter unit is in.
Enough of this shit talk, enjoy!
