Okay, first things first. I realize that the following question cannot get a perfect answer, but I'm looking for guesstimates on the following to prepare an estimating formula that will be "on the money". I will share when complete: 1. How many linear feet of bed edging would contain 1 cu yd. of mulch. I know some of the variables, but I need more heads to give me all of them. Var. 1. Much types: a. Double-cut Hardwood b. Triple-cut Hardwood c. Cypress d. Shredded yellow pine Each of these types will spread at a different rate. I need a guestimate on the rate of each type. Var. 2. A circular bed will have more linear ft. than a bed with only 1 side of edging. I'm looking for an average. De-weeding Services: If you had to estimate your average de-weeding job in the spring by the cu. ft. of cultivated area. How many "man minutes" would you bid per cu. ft.? Using "amount of mulch needed" as a guideline, at what point do you think the variables could get out of hand to the point that a guesstimate would be too off? I was thinking 10 yards. Are there any other variables that you would equate into a "perfect estimating equation"?
