Need a little help with my first block retaining wall estimate. I have built plenty of them before, but this is my first bid since starting my own company. The wall is 75' x 3' and the hill has been recently graded and excavated, therefore little excavation is required for the retaining wall. If the paver blocks are around $6 per sq. foot, what would you guys think would be a good estimate for this relatively simple wall job? I figure I will backfill with my crusher run and put in a 4'' drainage pipe, so this cost must be accounted for as well. Crusher-run is around $35 a yard. Also, the customer wanted a price for a dry laid flagstone wall, so they could compare prices. $25-30 per face foot sound about right for everything included (crusher-run, drainage pipe, labor, etc..) Thanks for the input, I'll post some pics when I am done.
