    I am putting together a bid for redoing a parking lot. It is not asphalt it will be white lime stone. Total sq.ft. is close to 89,000. I plan on using a cat d3 dozer, a cat roller 66", deere ct322 with a 78" bucket and a 6 way dozer blade and a water truck. The parking lot has a lot of wash out, low areas and pot holes. There are a few high areas in the corners I will knock them down. Then bring in the new lime stone I estimated around 1000-1200 tons. How long do y'all think it will take to do and what would be a good bid for the job not counting the price of the lime stone. If I knew how to attach pictures I would show the parking lot. Any help would be great.

    hi mike,

    It sounds like there is already a existing base and you are just going to put some more aggregare down to fill up low spots, level out and make a decent appearance. I calculated that you will me putting down approx 2.5" of material. Its hard to say how long you will take because all companies are different. Operator experience will be a HUGE factor in this as well as machine size. That lot is about 2 acres. 1 day for prep(i.e working with existing material on site, leveling off areas etc....) and one day to add ne material and 1 day(MAX) to tamp deal with other stuff etc...) Its really hard for me to say, but that is what I would estimate. And instead of screenings why dont you use a clear gravel (1/2" or 3/4") It would be cleaner but the material would be a little more.

    sounds like a fun machine project!! Have fun!

    This project is on Perdido Key Florida which is by Pensacola. The only rock allowed on the Key is white. Does anyone know how to post pictures.

    Sounds like a three day job with operator and labourer. You need a hand organising dump trucks, keeping clean around the edges, operating the laser etc etc. I'd be real happy if I got it done in three day. We recently did one larger with crushed limestone and roadbase, and it took three days with Loader, Skid, and 8 tonne roller with two operators and one labourer. It depends a lot on the shape of the area.

    Like the others i would say 3 days, day one you can come in and level things out get your sub base ready, then you could probably start hauling rock in later that day. Good truck drives that know how to spread dump will makes things go much smoother. one operator and a labourer, the labourer could hop on the roller when he's not busy doing something else. Forgot to ask how far away is your pit, and how many trucks can you get?

    The rock company said they will have 4 or 5 trucks available. I have talked with some people wome say you want to grade 2 inches high then pack it in and some say 1 inch when working with lime stone. any thoughts.

    Your ABSOLUTELY fine to compact in a 2" lift with the size of compaction equipment you will be running. Doing it twice wouyld be a waste of time and money.
    The only problem that I can see you having with the 3 day time constraint is the deliveries. I think you will be getting somewhere in the 40 tria-axle truck loads of material. Like others have posted I hope there is a pit near by. The best option that I have thought of for you to do is hire a trucking company for the day and have them do the runs to the pit for you. If you can get your hands on a big enough trucking company they will probably lend you a fleet of 8 trucks for the day. It will probably be your best bet to finish the work in 3 days. The pit will more than likely have other orders to fullfill at the same time, thus not being able to meet your demands.

    One substitution I would make would be to probably loose the dozer (unless its yours and your not using for anything else) and add a grader. Much faster and much cleaner finish.

    You'd break your neck having to back drag with that dozer all day. Get a grader (and an operator if need be) and save yourself some headaches.

    the grader would blow his budget most likely.
