How long should it take to auto scrub/propane buff/dust mop a 40,000 sq. ft. food market?


Using the handy and famous ISSA 540 Cleaning Times booklet, now available in electronic format, (see, you get the following:
1) dust mop with 36" head - 3.2 hours
2) propane buff with 24" rotary - 2.1 hours
3) auto scrub with 32" machine - 2.8 hours.
Total time - 8.1 hours plus make ready and clean-up.
I did the math for you, and you need to note that there are variables as well as other choices for equipment lessening the production times I cited.
May I suggest you order the booklet in any form from ISSA and use it for starting times on future projects?
