I have the beginnings of a plan for a 30w x 40 pole barn next year. Plan to do one 10x10 overhead door in the center to keep costs down and going with 12' side walls. I did a Menards estimate for the materials and it came to about $7800. with 2' overhangs and a walk door insulated roof (only) and more "upgrades". I got a neighbor who is a contractor that's going to price me a similar (maybe better quality) building as well as his labor to erect. Also, considering a roof extension for a "lean to" on the lee side of the building for implement storage.
Been considering either crushed rock for the floor or 4" concrete with some rebar reinforcement and old wire around the outside, lower traffic areas. I want to store my tractor and implements as well as a 22 foot boat and trailer in the winter. The crushed rock concerns me some...as I get concerned mice and burrowing critters will get into the boat upholstery.
My question is: does anyone have a good estimate of the concrete costs for the 4" floor at today's prices? I know its a major cost....but a nice even floor makes life so much better.
