Do not tell me to figure my cost and add profit because I will need to go out an buy portables so I will not make money this time
Luis I wouldn't buy the units just yet, I'd go to the rental yard and rent them for the job. Rental is cheap and most rental yards have the major brands. Then after you've made a little money you can look at buying a portable. As far as production, 600-700 sq/ft an hour if you have someone to handle the bucket brigade. 15-16 hours, divided by two setups 7-8 hour day.
11,000 sq/ft how much do you want to make an hour? 11,000 sq/ft x .15 =$1650.00
or $1650.00 divided by 16 man hours,
$103.12 an hour.
You could also Encap it with a couple of Cimex's 1200-1500 sqft an hour and do the same job in half the time. Even if you charged as little as .12 sq/ft you would come out great. 11,000sq/ft x .12 =$1,320.00, divided by 8-man hours for
$165.00 a man hour.With two Cimex's you'll been done by noon if you start at 8:00 AM....well maybe.
