i have a customer who just installed a pool in his backyard. the back yard is on somewhat of a slope so the pool is all the way at the end of the yard maybe 100 yards off the house. they want a retaining wall installed because of the slope. its is pretty much dug out because of the pool. the wall is going to be 75 x 3 with 2 steps in the middle of the wall going to the pool.so i figure what i have to do i just level off what is dug out with a bobcat, lay 6 inch of 3/4, put up the wall and step, back fill with geo grid and 3/4.the cost of the material is around 4500.00 and is in a upscale neighborhood. i was wondering what you guys would charge to do this with yourself and 2 guys????
