Hi Everybody,
I’m a newbie here. I’m a stone restoration specialist, tile/grout cleaner and long time carpet cleaner. My friend from my church works with this company which owns a few warehouses, one of which has a lease expiring in April. I’ve done some minimal work for them before and my friend is going to do what he can to help me get the job. The tenant has been there 15 yrs, does a lot of metal cutting with lasers, etc. Apparently no in dept cleaning has been done there in the last 15 yrs. Apparently the tenant needs to have the place “cleaned up some” when they leave so they need to do some cleaning to a certain extent.
The bottom line is that the owners need the cement warehouse walls and the partially painted concrete floors cleaned for a new future tenant. The walls need to be cleaned so they are ready for painting. There is no tenant in mind yet so, for now, regarding the concrete floors, they want them cleaned for a new tenant move in.
For me, I’ve never done a job like this on this large of a scope. The concrete floors total approximately 22,000 square feet. The cement walls are 25’ high, in which there is approximately 500 linear feet of 25’ walls(12,500sf). There is another 125’ approximately of 15’ walls that are over the office section of the building. The office ceilings are covered by plywood.
My initial questions are:
1. What type of equipment would be best utilized for doing this job? I’ve done considerable pressure washing with my truck mount unit before, but it is limited to 1500 psi. I’m thinking of renting a 3500psi heated unit for pressure washing the walls and floors. Might I rent something bigger? What special type of wand attachments might I consider for this project? I’m also thinking of a 21” circular pressure washer on wheels for the floors. Doing some research re rental yards. I'm liking this Nilfisk-Advance Captor 4800 Ride on machine which has water supply, vacuum, waste tank, brushes. 48" path. I'm thinking of a heavy duty ride on machine like this, then I could consider using a high pressure surface cleaner(21") after it for any extra cleaning,(perhaps I don't even need this) then come back by with the Captor 4800 again. It says it can easily clean 85k sf per hour. I only have 26k sf of flooring. Sounds like I would have plenty of time in 1 rental day to go over the floor several times if needed. $710 per day.
1. A key cleaning question I have is how many sf (on the average) of a 25’ wall can be pressure cleaned per hour? Would a specific type of wand or jet be more suitable than another for this type of job?
The collected grime on the walls is mainly comprised of garnet dust and metal dust. (Apparently, Garnet is a natural mineral, a hard silicate compound which is treated as a gemstone when it has fine colour and clarity. It is used in preference to Silica sand to overcome the shortcomings of raw silica.)
Thanks, Kent
2. Very importantly, what might the competition be pricing this project at? The tenant is responsible for a certain amount, the owners for the balance for the results I’ve mentioned above. Apparently, if the tenant doesn’t have it cleaned, the owners will deduct their share from their deposit.
Thank you so much in advance for your help and advice. I appreciate it very much and look forward to interaction with the many professional on this site.
