30x40 Pole Barn Demo, two 40yd roll offs?

Customer is wanting to demo a 30x40 pole barn, garage doors are only 8ft so I'm guessing highest point on the roof truss is maybe 13ft max. No interior framing or anything to remove, just the building shell.
The point is, it is not a big building.

What are the odds of me packing everything out in two 40yd roll offs with a 32k-ish excavator? Max load is 10 tons.

Crazy? Impossible? Just plan on 3 roll offs?

Thanks!

Just the building? Is there a concrete slab and does it have to be removed?

4" concrete slab is getting trucked with a tandem to the recycler. 15yd hopefully get it in 2 loads.

Just the building is going in the bins. Building is entirely wood minus shingle roof and maybe a few pieces of flashing here and there.

Ok, blew the height guess. It's probably 15-16ft when looking at the doors for scale.
Sorry photos sort of suck.

My basic rule of thumb for residential demo is 1000 SF = 100 CY in the can. However that's for interior walls, drywall, etc. I'll use a factor up or down on the SF to adjust for a structure that has alot of interior walls or is packed with personal furnishings.

If the building is free span with no interior walls or personal belongings you should be able to get it into 2- 40 yards. You'll have to process the debris down as the plywood roof and walls will be the bulkiest part.

For concrete demo haul off (concrete that is not pulverized just ripped up with a hoe) I use 5 CY of pour back = 1 tandem load. Also I use a 15-20% swell factor on concrete. That 30x40 building with 4" slab measures just shy of 15 CY - 14.67 CY. I would figure 4 tandem loads of concrete with a 15% swell factor. Always round up on truck loads, always seem to use that extra load at the end.:)

Much appreciated on sharing your guidelines / estimate numbers! Sounds like I'm in the right ballpark. The 3rd bin was included in the bid but said I could maybe squeeze it on 2. Just wanted to make sure it wasnt going to be 5 o_O

I usually come in pretty close on my quantities and trucking, for moving rock and aggregates at least. I just don't do a lot of demo work - everyone is building like crazy, not so much tearing down.

But you're absolutely right, always plan on an extra load / truck / bin / whatever, because you end up needing it.

If the structure is good why not disassemble and on sell it but quote the price for demolition ?

Landtrax to a demo man it doesn't matter how nice a building it is because it all looks like $$.:D

Once we tore down a very nice red iron and brick restaurant with mahogany bar (that job is in this thread somewhere) and they built back a wood framed Olive Garden. I still have the red iron beams on our yard as we salvaged as much of the structure we could.

Restaurant building we tore down for a new Olive Garden -

A fairly new Pep Boys we tore down for a new O'reilly Auto parts. We dismantled the red iron frame and still have it on the yard too. Eventually I would like to erect it for a shop.

Well I guess that's a good enough hijack - I can't help myself with demo discussions.:oops::D

The barn is actually in very good shape, lots of good lumber and my immediate thought was to save it for myself or try and sell some of it off. I will definitely be saving the pressure treated structural beams that hold everything up, but I dont have storage space for an entire barn at the moment.

Owner bought the home a few years ago and whoever put the shop in originally obviously didnt have large vehicles / trailers / tractors / etc.
Its cheaper for him to scrape it all and pay for a new 40x60 with 14' doors to actually fit something in than it is to retrofit the existing building.

Bit of a waste, but sort of the only option to have an actual barn.

I appreciate some of the shirt tail estimates. I like knowing some general cost. What does dump space cost?

Was the Pep Boys where you guys were pushing the roof with the 953 from inside the building?

It's crazy how many outbuildings get built with just 2 8x8 doors.

Is this anywhere near southwest Michigan? I need a storage building/man cave

Well here construction and demolition debris is usually priced per ton, I think there are a few landfills that charge by the CY but they are in the minority.

The tonnage pricing ranges from $22 to $30 a ton depending on the landfill. A residential demo using 30 yard cans will average 9 tons per can. The first 30's will be light and the last 30's will be heavy but they will average 9 tons.

Yep - that's the one.
