We just completed 2 small raised planters for a vegetable garden for one of my maintenance clients. We did an 8" deep footing 12" wide. They are identical 15-ft long by 4-ft wide, outside dimensions. Built with 8x8x16's we grouted every other cell and used rebar, sand filled the other cells, capped it with 2" soaps and waterproofed the inside footing to top. We had to get the materials about 80-ft and over a 6 ft fence wall. We don't do block normally but this is a good client and no one else would come out to bid it. We had 90 hours into this job and I don't want my client to have to pay for on the job training. What is a reasonable cost for this project either in hours or total cost. Thanks in advance for any help from the pro's.
