I'm just trying to refine my estimating process and I'm sratching my head about my sodding price. 1- Does anyone know how many sq.ft. per hour a labourer can install peat sod? I'm using about 300 sq.ft. if there isn't a lot of cutting (on a typical city lot 50x110) 2- Also, how much topsoil can a labourer spread and rough grade in an hour at 5inches deep in a tight spot compared to wide open. (300sq.yd. vs 600sq.yd.) 3- A labourer Fine grading by hand per sq.ft.? Either I'm out to lunch with my productivity or I'll have to switch suppliers. Anybody know how to get cheap screened topsoil or find a steal on sod?
