Does anyone measure their properties,keep track of the time to plow an area and then figure time per square foot for certain snowfall amounts (1-3 3-6 ect). I have to price a property that has 4 lots totaling @29,000 sf. The problem I'm facing is alot of the snow has to be pushed out of one area between all the buildings (@11,000 sf). I figure this will take alot of extra time and will double from 1-3 and 3-6 inches. Any input or figures will be appreciated
