The usual reason for cost overruns is design changes.

Someone (or a committee) accepts the initial design, and then as work
progresses, people notice things they don't like about the initial
design.

"What?  The perimiter berm is only 4 meters?  Local spec is 5 meters.
It'll have to be higher."

"Well, the Imperial spec is 4 meters...."

"Yeah, but the locals require 5.  "

"That should have been caught in the review."

"Whoops.  Locals must have been snoozing."
