commercial Customer wants an estimate on tearing up exsisting grass, put down topsoil and re-seeding. No irragation. Told customer i could not garuntee end results with out water. Was told to still submit estimate. Currently it is mostly weeds with a lot of bare spots. Soil is hard and compact, looks like orange sand and clay mix. ( lots of small rocks) What would be the best way to tackle this job? I have access to Dump truck and bobcat. will i need an excavation permit for this job? how much topsoil? if my calculations are correct nearly 1000 yds if 3" deep Thinking i miss calculated here. Give me some numbers. Area - 120,200 Sq ft. Nearly 3 Acres mostly flat, slight slope towards woods. Was thinking of scraping exsisting grass with bobcat, spread new topsoil, spread seed. If i need an excavation permit, will also need silt fence around property line. Thinking this is a 4 day job. 10 hours a day. Tell me some ideas on how to do the job and prices. I have figured up some prices but just want to double check.
