The fact that your asking for advice on a 3 storey building makes me nervous!
My advice would be to employ someone who's experienced!
And what is the fluff factor???
Are you knocking it down or making it a dress?

i can not give you perfect advice here with what little i have to go on. but i will first say that a skilled wrecker with a 300 can handle this building with out any issue. it should take him 2 full days to have the building on the ground. remember that in demo dropping the building is the easy part. picking and cleaning the pile before you load it out is the real skill.
also to decrease you cost, you might want to gut and clear the building first. you can send all that to landfill, and then be left with mostly steel and concrete. the concrete will go for free, and in some areas of the nation they pay up to 5 bucks a ton for it. also with the steel, cutting it to size will increase you revenues.
anything else i might be able to help you with, call me. Hugh Carroll 716-563-1710
On second thoughts, the 14" measurement was made on the exterior of the buiding and is probably not a good representative sample. It should be more like 4"-6" for a residential hotel type structure. If this is the case would a 300 or somewhat smaller machine be sufficient? I'm still a little concerned about the vertical reach being that this is a 3 story structure with a gable roof.
If you take the time to crush the debris with the thumb would 10% be to minimal of a fluff factor. Thanks for your response.
RCS:
14" thick floors? Was it an industrial building? If that is the thickness and you don't want to mix the landfillable debris with the clean concrete I would gut (soft strip out the C&D) first with a bobcat which 14" floors will support. If its all masonry I would use a bigger machine than a 75000lb excavator - just because of the floors and the reach. With a PC600 w/concrete pulverizer you should be able to demolish 3-4000 SF a day. Depending on how large you leave your concrete pieces your debris can have a fluff of 50%. Make sure you have an asbestos survey, and you do an EPA notification for whatever region you are in. The EPA fines for non-notification are now $24,000 per occurrance. Good luck and be safe.
Can any one give me a little advice on the demo of a 3 story block building (hotel style) 210'L X 42'W X 40'H. Plenty of room to maneauver around it, no overhead restrictions. I'm sure each floor is made of concrete that appears to be 14" thick and I'm sure slam full of rebar.
1. Will I be able to do this with a 300 class trackhoe or will i need a long reach? I believe that I will be able to build a ramp with debris as I pull it down.
2. Will the 300 handle the floor deck with all that rebar?
3. I am an above average trackhoe operator but posess little demo experience with a structure this tall. What should my production rate of just tear down be (no haul off included)I will be salvaging all copper and steel of course.
3. I feel like I can compute the cubic yardage by simply measuring walls and floors and adding a "Fluff" factor of about 10%. Is that enough fluff factor? and is there a better way to compute?
4. Lastly, any and all input and recomendations from you seasoned pros is greatly appreciated:yesway:.
Thanks in advance
