Sounds like you need a line pump. Let the redi mix company know you'll be pumping the concrete.
Seems this will be an issue. building is 60x100. Will have 1, 12x14 OH door and some window openings around the building. Due to having foam under slab and radiant tube, I cannot back a truck into the building.
Every finisher I have talked to pretty much does not want the job, quoting nearly what the concrete costs just to place and finish.
What I need to do is spoon feel the concrete team by working out this placement problem. I have not worked around pump trucks much but one guy mentioned if the flex tube is too long, the rock likes to try and separate from the portand. Don't need that.
Due to a strict air barrier detail in the exterior of the building, I cannot just peel off roofing. I know there is a way. I am not the first person to pour a floor in a building.
Obviously, I can throw enough dollars at the problem that I can hand 100 men 5gal buckets and we got it but I don't have bottomless pockets.
Thanks guys. As far ad "adjustments", is this a slump adjustment? I need maximum performance from this floor so would like to carefully select mix and slump. Hoping I don't take a hit due to the pump requirement?
The guys I plan to work with have an in-house test lab so they should be able to help. a std 3500psi concrete should work fine. I just don't want to run down to 6" slump just to pump it. I believe they could kick in a plasticizer but I doubt I wanna pay for it.

Thanks. I am still at a point of calculating some things for the concrete. Just more complicated due to that stupid foam under it but I gotta have it. I hope my hours burned running numbers works out. I don't want to walk on that slab with 80k lbs of forklift and pop it.
Wish I could get my hands on an old IR compactor I ran on a bridge job for a month. Sweetheart had variable frequency and amplitude and I could make dirt hard enough to do a burnout on. Big sewer job.
Speaking from a plumbers view, a buggy running on top of tubing scares me. Even with plywood.jomama - I am curious what the capacity is on the buggies? I have used them for a few things but not a big pour. Can you place crete pretty quick with those or is a line pump the better way? 120yd pour.
