|- 
| '''on_build_start'''
| colspan=3 | A block of [[Effects]] to be executed to the solar system scope when the construction or upgrade begins. Vanilla unused. (Solar System scope, FROM = builder empire, FROMFROM = the megastructure to be upgraded into this)
|- 
| '''on_build_cancel'''
| colspan=2 | A block of [[Effects]] to be executed to the solar system scope when the construction is canceled. Vanilla unused. (Solar System scope, FROM = builder empire)
| style="text-align: center;" | {{icon|no}}
|- 
| '''on_build_complete'''
