Im putting in a bid for my first wall for a customer who knows I'm new at all this. I have done smaller walls nothing like this. I checked out the laws and you dont need a permit if its no more then 2' high. Heres the specs: 100'x2' high. Im using Keystones Builder Mini Unit which are 4"hx 18"l. Using keystones chart it says that I need about 400 of these which will make it 6 courses high. These blocks costs 3.30 a peice which turns out to be about $1300. Does that all seem right so far? Then I'm filing in the area thats 4 feet wide to a fence with some 3/4 clean gravel(also using it for backfill) and bringing in topsoil to fill the last foot or so and mulching. The base i'll be using is 3/4 minus. Im going to clear the footing out about 18 inches and fill with the 3/4 minus and use a plate compactor that will put me back about 90 bucks for the day. Im having one other guy help me with this and were splitting everything 50/50 and asking for 25% down. Ill be charginf $4900 for the job and from what others have told me it should take us about 4 days to do working 8 hours. What do you all think. AM I out of my league with pricing and time?
