I'm building 2 retaining walls for a customer with basic Anchor diamond block. The lower wall is 70x3 (11 pallets) with a slight 20ft curve. Not a whole lot of cuts and all the same height. The upper wall is 70x3 with 2 curves on each side. A lot of cutting for the caps and each row will step down on the ends. I bid the first wall (lower) for $6700. Than the upper wall was needed for the pool deck to be poored. I bid this wall for $6500 which will be a lot more work. The customer asked if I could do them both for $8500 since his son can do the stacking. Thats the easiest part of the build. I have to do the base, base row, backfill correctly, break the ends of the caps and block, and finally cut in all the caps. What do you all think about this situation? That's my price but I'm curiuos to hear what other do in these situations.
