I started a landscaping company this year and I'm bidding on my first retaining wall job. The wall will be 25 feet long with about 15 feet being at 4' tall and then tapering down to 2 feet. There currently is a retaining wall of boulders that was made by the home builder probably 15 years ago that has to be removed. The homeowner said we can find a place around the property to drop the rocks so I dont have to remove them. This is what I've got: Wall block: $1400 Gravel for Base: $20 Crushed stone for behind: $100 delivered Skid steer rental: $300 Hired labor: $200 Cut off saw rental: $100 Fabric: $100 Total: $2220 I was figuring I should make about $1000 which would bring the total to $3220. To me that sounds like a lot of money for a 100 square foot retaining wall. What do you guys think?
