Bidding a low retaining wall job labor only.
I was asked to bid an L shaped retaining wall (only 36" tall). The owner currently has RR ties and will remove them and purchase the blocks, gravel, sand, fabric etc. for the project. They want me to do install only (taking away my materials mark up). One section is 22' the other is 15'. Is $350 about right? too low? Also should I interlock the corner?
