Customer wants his planting beds around his house lowered. Total length around house is 143 feet. Average width is 5 feet. He wants beds lowered about 3 inches. There are a total of 24 plants or very small bushes that would need replanted. Soil removed can be wheelbarrowed to rear of property and dumped, only about 50-75 feet away. I would have a total of 2 people doing this job. Please give me some idea of time it would take. I figured it out that it would be about 6.6 cubic yards of soil that needs to be removed. Thanks!
