Locating 500 points on the ground cheaply
I have a project (I'm the engineer) where I need to have an excavator do a tiny bit of dirt work at 500 locations on the ground. The locations are random - it doesn't really matter where they are - but I suspect the operator will want to know where to dig so he can focus on digging rather than figuring out where to dig.
What is the cheapest way to communicate to the operator the locations of the 500 points that he needs to dig? I can set out flags, but that would require 1-2 days work. It is easy to use AutoCAD to generate the 500 points and I could provide a coordinate list to the operator, but Smartphone accuracy is poor and some of the points might lie outside the work boundary, which would be bad.
I'm thinking I'll just need to buckle down and set out 500 flags so the operator can work as efficiently as possible.
The cheapest way to do anything, is to do it right the first time. Focus on meeting the objectives of the work before focusing on cost.
I have no idea what you are trying to accomplish digging 500 holes, but is there a chance that the location of these "random" spots will need to be known in the future? If so, hire a surveyor to help you out, it probably will be cheaper in the long run if you are keeping track of locations and related information now than at some point in the future.
Who's going to make sure the excavation operator doesn't try to pull a fast one and only dig 499 holes? ?
The cheapest way is just to do it yourself. The Operator probably charges by the hour maybe the day, the less he needs to think about where to dig, and just to dig and plant a tree, will also save you money. Let him just do his job of digging.
By the way how deep do these holes need to be?
8 to 12" you may be able to get a local Boy Scout troop to help you out.
