Calculating Fencing Costs

Full digitization of fence lines and posts in GIS software makes the basic calculations simple. GIS provides geometry of the digital features including fence length:

Total Length of Permanent Fencing

(In “Sum” field)

FenceLength

Also determined by GIS, I have 26 wooden corner posts and 162 steel line posts in the full phase fence plans. Breaking it down to Phase 1-only shows a need of 23 wood and 119 steel posts.

Those figures alone let me derive most of the other materials needed in simple excel formulas. For example, each wood post requires insulators for both the spark and ground wires, while the leaving the steel posts uninsulated to the ground wire acts to ground it! However I am still trying to research if it is desirable to only leave the steel posts uninsulated at specific intervals. I am also debating if I need to install a gate at every paddock. For now the last question is factored in as affirmative.

For Phase 1 Fencing:

Now with 3 wires added for phase 2 plans, the calculations are as follows:

Other than buying the animals themselves, this should be the biggest investment I have to make!
