I am wondering what price to charge along with the recommended amount of people/labor to perform a one-time clean given the following. Sweep and Mop 30,000 sq. ft. concrete warehouse light dust, light dirt using regular commercial size cotton mop(s) and bucket(s) Location - Cincinnati, OH If I wasn't specific enough, please give me a price with a given scenario(s) if possible.


With an 24" push broom, you will spend about 8 man-hours just sweeping out the place and how effective that will be depends on the smoothness of the concrete. On the other hand, the use of a 36" rider sweeper with vac to get the fine stuff will take about 1.25 hours.
If you use the 24 oz. mop and press setup you describe, the time will run around 12 hours and that is with a water source really close by to save running time. Use a 32" auto scrubber and your time drops to about 2 hours.
A decision to price out a job this size without considering renting production equipment is unwise. You will spend a lot of time and energy for not much money because your price for doing 20 hours of work will not look good going up against that of someone who intends to spend 3.5 to 4 hours and probably do a better job.
Note that the times given above are average and could be way too low depending on the amount of dust, the surface, etc. Look to renting some equipment to reduce the time factor and you may have a good project.
