I've been doing mostly maintenance for some time now. Have a client with an existing wall that was not properly built. It will need to be torn down and rebuilt. The dimensions are 6.5' X30'. Currently there is no drainage behind the wall. How would you guys price removing the wall that is there with a lot of the soil behind the wall and reconstructing the wall properly? I know the correct way to do this, just not familiar with how to price it. Thanks for any help!
