Looking For A Few Pointers On A First Time House Demo....

Little

I'm looking to do a house demolition over by me and just have a few questions. Anyone have any real idea or some kind of rough number to follow in figuring out how many dumpsters are needed? Any ways i should be looking to demo to keep it as clean as possible? Going to be renting a machine with grapple to do the demo. How long does it usually take to demo say a 2 story 2000sf home? Thanks

Easily have it down in a day. Probably down and loaded in a day if you have enough trucks running, or a quick enough turn around for the trucks.

I saw a demo recently with a house about the size you're talking about. I drove by it about 5 times within two days of its work. It took two days and there was still a pile left. A couple days later they got rid of that pile.

It was a smaller machine too....maybe a 12 ton or so.

pull the wood into a pile, crawl that excavator up on top, start spinning cookies....will turn that lumber into toothpicks GREATLY reducing the amount you have to haul out.....BUT, make sure you have a shield under your undercarriage to guard your drive motor swivel/hoses, etc.

I've never been good at estimating for demo. Just make sure that you crunch it up really good to save on space. The cans get pretty expensive. I have a restaurant to do within the next couple weeks.

I use 120 yard walking floor semi trailers. 2 loads and your done. Just have to make sure you have a big enough machine to load. Last house I did was about 1800 sq ft with attached garage. We had about 8 hrs taking it down and loading it out. Not sure about your area but I can hire a semi with walking floor trailer for 75.00 hr plus tipping fee.

Hey CAT 385, do you get to knock down houses with a machine that big. That must be a heck a lot of fun and you can really feel the power.

I use the number of 30 cu/yds per 250 sq/ft of home. Works out to about 8 dumpsters if you walk the pile down....and then you do have foundation.

I used to think it was fun...but the dust kills me. I have a bid in to tear down an old lumber yard, and then erect mini storages on the site.

Or try to schedule it for a rainy day.

I would say 6-8 30Cy containers. The house should be down in 1/2 hour if using a excavator with a 2 over 3 grapple and have room. If you have room try to have at least 1 30 and 20 for concrete on site and have the container company give you a truck and 2 more boxes just for you until you finish. I always figure 2-3 day total for demo and final cleanup with sorting and getting rid of all the debris, concrete, stumps scarp metal and a final cleanup. But I have done house in one day complete if the dump is close enough. Where in Jersy you doing the demo?

Nac!!! Where have you Been???


Little,

35 years ago as a 19 year old I worked for an outfit that we would have to bring that house down, load it on 75 yd trailers, fill the cellar hole and rough grade in 10 hours or less (or you didn't have a job the next day, I'm not exagerating). These were on small pieces of property in crowded nieghborhoods. This was with a 1 spotter, 1 operator, 1 laborer, 1 48,000 lb tracked loader, and a minimum of 3 trailer dumps.

Planning in demo goes a long way. Knowing the structure type is also a big one. There are 2,000 sf homes that are nothing but some walls, a floor and a roof. With very little interior partition or layers of construction. There are older homes with multiple layers of everything and really well built which equals more volume.

A quick figure that we used was take the outside dimensions of the home and figure it's volume in cubic yards. multiply that number by .15. Then looking at the construction type and materials multiply that number by 1.5 or 2. It's come awful close when figuring.

An operator who keeps working to reduce and seperate the material while waiting for containers. While keeping the site clean and accessable.
