Got a call for a lawn install of 27K sqft. The HO had a major patio/ retaining wall installed and the contractor isn't putting the lawn back in, he simply did a rough grade and is leaving it at that. There are basically two areas, one is about 11K and the other is 16K. Site access is no problem on the 11K, but the 16K'er has virtually no truck/machine access to drop topsoil, it will have to be dumped over an embankment (that will be lawn in the end) and then shuttled to the lawn (farthest point about 150' away) to be spread to raise the grade by 2". All together I estimate to use 180yds topsoil. Whats the best method to attack this? My plan is to move all the topsoil with a large skid steer from the hill to the new lawn arrea. While I'm shuttling the topsoil I will have the grading done by my cousin with a 6way dozer blade Komatsu. Then final rake and seed,fert and hay it with some manual labor. I will also be looking into hydroseed if the HO can assure me that everything will stay watered.
