What would be a ballpark cost figure for Rock excavarion per CY in US$.
Operation includes Drilling, filling explosive, Blasting and removal on side of the excavation (only pushing 100'aside) No loading and hauling.
I neeed to acquire 1:20000 elevation maps for British Columbia. I used to have some addresses for free download but now I am not able to get hold of them. Is anybody in position to help?
Thank you and have a nice day
