I don't know but if you have a tough time getting the info it would be a good idea to call at least 3 contratistas in the capital to find out the going rates. Also, they will charge you for the clearing and grubbing by acre and the dirt moving by m3. In addition, they may charge you money to dispose of the excess material off site.
Thanks Chip,
Just got a quote to clear the grubble and remove the dirt, and take it off site
RD$250,000!. This sounds a bit excessive. I know you dont know the lot, but would you to care to speculate on the cost? (5000 sqm).
If you think you will have to move a lot of dirt you might want to get the property surveyed and have an engineer calculate the volume that would have to be moved. They could also tell you if it would be really necessary to dispose of it offsite(more expensive) than to move it around on the site.
BTW, I know a very good fair surveyor who lives works for the La Romana Corporation as the head surveyor who can do this stuff on the side. He is German but speaks Spanish fluently as well as English - not so fluently but good.
I myself am a civil engineer and know one or two in Santiago as well if you want to contact them.
