    I have a few upcoming bids that I have give the once over look. Some of them have terribly irregular shaped turf areas spread out around parking lots, islands ect.

    I want to have really accurate data for all my bids and accounts this year. But I can't figure out a way to get anywhere near accurate square footage figures at these odd places.

    Is there a simple answer I'm missing or something I forgot from math class? :blush:

    Guess. Then if you are too low, just raise your price. If you went too high, extra profit.

    I measure off many weird shape lawns every year. I square off everything I can. Even if I sometimes need to break it down into several small pieces. You should be able to get within a few sf each time. Don't worry about being 100% accurate.

    I like hoss's idea...square then off. Then approximate and add in the remainder.

    Jobs with odd and irregular-shaped areas I always add an additional 15-20% to the bid. These kinds of jobs just seem to take longer (probably because you have to make more turns or can't mow as fast) than ones that are square or rectangular.
  6. The below works for odd shaped areas. Also use geometric formulas for circles, triangles, etc. Let me know if you need those.

    Dont make it so complicated.I can appreciate you wanting to bid as accurately as possible,but as you gain experience-you should be able to walk a property and bid it without measuring.I bid all my jobs by eyeballing it.If you have a doubt on a bid - just bid it a little high-this method works great for me-I rarely under bid a joband rarely lose a job due to over bidding.I try to keep it as simple as possible.

    We measure everything. I do not agree with eyeballing it. Eyeballing it is going to loose you money.

    Nebraska, please explain how walking a lawn loses you money. We can walk the lawn and estimate within 3 or 4 minutes of what it will take to be completed. We know what we want to make for that amount of time. Has worked fine for us. Also if you have several houses on the same street with very similar lawns, you should know almost exactly how long you will be there. I am not talking about huge commercial properties, just residentials and small commercial.

    Bob, If I had a shape like that I would give it a 125' x 50'. rounding up to make sure. I wouldn't spend the extra time to save the customer a couple of bucks when they may try to nickel and dime you anyway. my 0.02
