I'm bidding on a contract next spring on two local parks and a cemetary, Park 1: 5 acres, 200 trees, 300 feet of rail fence. Park 2: 7.5 acres, 2 buildings, 50 trees Cemetary: In our climate to keep it looking good, we need to mow on a more than weekly basis for 1.5 months of the year, (Mid May through June) then less frequently for the rest of the season (2-3 weeks for August through September, with a final mowing in October. Any of you have spread sheets or rules of thumb for estimating? E.g. Once I have some experience, I'd have a spread sheet that took into account: Travel time: XX minutes Area XX acreas Edges XX feet Trees XX trees And the calculations would work something like this: * There is going to be loading and unloading time, so travel time is really 40 + travel time, assuming a load/unload at each end. * The area divided by the mowing speed times the mowing width times a fudge factor gives you the mowing time. (There are some unit issues here too.) The fudge factor takes into account the overlapp on the strips. * Edges are those that require trimming. * Trees are are really edges about 8 feet long, but you probably end up spend as much time walking to the next one as you do trimming one. * But trees also add to the mowing time, because you have to go around each one, and there will be more overlap. So -- any tips for estimating jobs?
