Commercial interior advice.

I'm looking at roughly 75,000 sq. ft. of interior washing (ceiling, walls, floor) for paint prep., and could use some input. This was previously a manufacturing facility, which is now completely empty. The main area (60,000 sq. ft.) is completely open other than the vertical supports, and is 32' tall at the 200' sides and 36' at the center. The ceiling is covered with reflective foil backed insulation, corrugated steel walls, with brick fire wall on two sides. On all surfaces there is a thin film of carbon and oils (from welding I assume) with not much other accumulated dirt like I've seen in other jobs. The room is being stripped of all unnecessary fixtures, but will have all the lights (plugs on all), outlets scattered around, and three large, high voltage panel areas. There will be live voltage throughout, but we can shut down areas as we go along, and can unplug the lights. There are no useful floor drains in any of the areas.

We have done some smaller projects on interior walls in this type of setting, but never ceilings or anything on this scale (interior). We know we need to use a neutral PH cleaning product that can be applied and rinsed off, that will not inhibit the paint performance. We also know that we will need 1 or 2 guys on the ground for water containment. The rooms will be heated, we can drive our trailered rigs inside and there is plenty of water source. We know low pressure will be necessary on the ceiling insulation and most other areas.

Hope I covered the majority of the issues here. So what I need help with is:

1) Suggestions on the type of cleaner to apply (preferably downstream).

2) Precautions to take working around the electrical areas. (Note - They will be replacing the existing light fixtures, but they will still be there during cleaning)

3) With two, experienced guys spraying, what would your time estimate be on sq. ft. per hour/day on the ceiling. (I figure this will take the most time. Yes, we will have motorized lifts. The competitors' bid states the entire job would take 5 days with 2 shifts of 2 crews. Don't know how many in a crew.)

4) Suggestions on water containment. (I have watched my competitor work on a similar project that I bid on, and they had just one guy on the floor with a walk behind janitors floor scrubber/vacuum, and that seemed to keep up to two sprayers. We got another portion of that job that wasn't PW related, so that's how I got to watch them.)

We are an experienced, competent PW company, looking at a "new" area of work, so please don't start with the "if you don't know, don't do it"! It has always been our practice to gather as much info and expertise when attempting to enter new areas of projects. That's why I'm posting this. I already know my competitors' pricing, and have an existing relationship with the customer, and good references from the painting people they're looking at. In other words, if I feel confident in performing this project safely, efficiently and to our quality standards, I can get it. Would equate to roughly 2 - 3 months of normal, winter revenue. It is also Phase I of the project, with continued work down the road, as well as another area of experience that we can build on.

Sorry for the length of this post, but wanted to relay most of the info without going back and forth. All help is greatly appreciated. If it's easier, you can call me directly at 262-305-4890. Happy Thanksgiving!!

I sent it again....the first one didn't bounce, probably went into a junk or spam file. I'm sending it to the email in your signature.

Lots of volume. The dirt doen't much matter, the new epoxies of today will bight into almost anything. The consern here is loose dust dirt sitting on the top side or anything. Cleaning welding shops can be a little tricky due to the welding fumes and time. We usally use a touch free equiment wash chemicial and rinse. For after you have done a section and it had driffed dried 75% go back and rinse again.

What you are looking for is a clean surface which has no foreign matter sitting on it. When you are washing the fabric insulation watch out for it will be brittle depending on the type of fabrication in the building.

Price it out at 1500.00 per day and a 150% margin of error time wize. Some jobs will go fast and some you can make a career out of them.

Thanks Daff. Could you give me more specifics on the cleaner you use (brand, chemical base)? I was up on the ceiling doing a test area, and it's pretty well in tact, but will still need to be careful.

Let's say you had two guys spraying on this job. How many days (8 hrs.) would you estimate it would take you. Again, the 60,000 sq. ft. room is completely empty and there are no obstructions anywhere. Thanks for your help.

I would break up the job into parts. For aech area will have different degees of difficulty and dirt. Take a 20'*20' area and think of the approximate time to clean, add the cost of chemicials and employees. Then take this time and double it. This will give you a margin of error to work with.

Any high quality industrial solvent (degreaser cleaner) will work good on this application, as before the key to paint prep is a grease and debris free finish. Painters woult care if the white area are still alittle yellow. They are there to paint and make it perfect.

Don't foget about the hidden costs, examples are bagging the lights pannels and anything else which shouldn't get wet. Allways insist on a manlift, without one your back will be killing you will be there twice as long and have poor results. Explain to the client that they should provide one to cut the costs between the wash guys and the painters. If he still refuses add the cost into the bill and add 30% for your out of pocket expences.

I have done further test areas with chems, and have that narrowed down. Will still need to think through what my coverage rate will be per gallon of dilluted chem, but can get pretty close.

I still need some input on timing. Again, very little obstruction anywhere, so can move pretty freely with lifts, and can drive my trailered rigs inside. I will have two hot water skid units operating, will spray chems on the ceiling with a paint sprayer....downstream on the wall sections. Two guys spraying and one guy on the floor with a walk behind, mechanical vacuum. We will tape off & bag wall outlets, and will have to bag & unbag lighting as we move along. for the entire 75,000 sq. ft., I am figuring 10 - 12 working days with 3 people. Does this seem reasonable. Any input is appreciated.

The time frame seems reasonable, although what about other clients can you be at two places at one time?? Another option is to bring in a temp employee and rent a hot water unit. Have the third unit dedicated to post wash washing. I don't know of the time frame allowed to complete the job. Normally clients need the job completred the day before they call you.

Good luck :)
