I think I know the right answer to this, but I’m having a hard time passing on this one because it’s big for us and there’s a high potential for future jobs.
The job is for approximately 150,000 square feet of parking surface plus walls, ceilings, elevator landings and 2 stair wells. The garage has basically been abandoned for around 3 years and there are very few cars that still park there. We will have 24 hour access to the facility with basically no cars to work around.
It’s a downtown facility and does not have security so there are a few people making this their home. We only saw a handful during the walk through today, but I would expect there to be more folks at night.
There are drains at the North and South end of each floor. On a couple of floors these drains appear to be clogged. The drains shouldn’t be too difficult to block. We will need to collect water and dispose of it off site.
There is water access on at least every other floor with garden hose bibs near the standpipe. I didn’t test any of these to see if they actually function but I will confirm.
The parking surface doesn’t appear to be that nasty and it gets worse from high to lower levels. The elevator landings are pretty nasty, but I does look like it will be pretty simple seal these up. There is also a chance the elevators can be shut down while we are there as the facility is technically closed.
I’m most concerned about the stair wells. They are terrible and I want to just light them up with straight SH. In this building there is about a 1 - 1.5" gap between the stairs and walls. Some of these are sealed others drain to who knows where. We’ll also need to figure out a way to reclaim water at the bottom of these as there are no drains and these stair wells end at an under ground tunnel connecting a few buildings.
The timing they have in mind for completing this job is about 1 week but it sounds like there is some flexibility.
From an equipment standpoint we’re looking to rent 1 if not 2 8GPM units and then use our 5.5 for the islands, elevator landings, rinsing, throwing down chemicals etc.
My contact for this garage mentioned his company keeps a database to keep track of what things should costs. Their internal discussion has this at somewhere between $18,000 - $30,000. This and the prospect of their being more opportunities to come has me really thinking about taking this risk. I will be comfortable subbing this out or bringing in a partner hopefully with some experience.
Any advice is much appreciated.
