+1 there's so much logistical costs involved in construction that the lay person wouldn't factor into it
first job out of college was building the san marino high football stadium in LA.
our single largest cost was getting trucks to come and remove excess soil and bring it to a dumping ground (like a new truck would arrive every 5 minutes) and then about a month later bringing all that soil back
this blew my mind, it seemed like they were mispending hundreds of thousands and my 21 year old "i know better than the world" mindest brought it up to the foreman and who would have known they'd actually factored in that stuff when making multi million dollar project decisions and this was indeed the cheapest way to go about it
