what would it take to demo these foundations...

[Landclearer]

Thanks CM!

 

[JBGASH]

I am trying to get an idea on what the bid would be to do the job for future reference, any one got an estimate figure in mind?

 

[clintm]

you know some how some way us dumb ol southern boys giter done every one and a while even a blind squirrel finds a nut once and a while.......

It's funny, I cut and pasted this thread link and sent it to one of my buddies. He replied, why are you even wasting your time, you must be really bored.

The way to handle this job with a concrete densifier is that you go to each foundation, crack the walls, crack the slab and munch the concrete on a small section of slab in the middle, back the truck up to each pile and load it out. If you are willing to work a long first day to overcome the mob/set up the whole job should take two days. One day processing, one day loading.

CM, just out of curiosity what does your example have to even remotely do with the original question?

Work tools for heavy equipment are for people who want to do the job as quickly and efficiently as possible and then move on to the next job. I notice from having worked in the South you guys like a slower pace and older equipment, either that or you need to increase your sales volume.

There is a reason why we won the big one. :usa

I'm glad you guys are happy with your work methodology, work pace and the amount of money it brings you. I'm sure working slower, with older, less expensive equipment, not bothering to invest in new technology and a smaller sales volume will lead to less stress and a longer life. You guys do indeed have it figured out.

The feelings mutual, I said my piece - now I'm bored with the discussion.

You have came on here recently (August 2014) and proceeded to preach to members how they are doing it wrong in a rather brash manner. Your first post on HEF was in this thread, not a good way to make friends IMO.

Furthermore, I don't understand nor really care why you have such animosity towards the south but coming on this Forum to stir any kind pot is something we frown on. There are plenty of places on the net you can go for that. Let's keep the discussion here on HEF about heavy equipment and the associated means and methods.:cool2

Keep in mind one of the Forum rules located here - https://www.heavyequipmentforums.co...Equipment-Forums-Rules-and-Posting-Guidelines

An Internet troll, or simply troll in internet slang, is someone who posts controversial, inflammatory, irrelevant or off-topic messages in an online community, such as an online discussion forum or chat room, with the intention of provoking other users into an emotional response or to generally disrupt normal on-topic discussion (source Wikipedia). Trolling is prohibited and will result in dismissal from the Board.

HEF has members from around the world with different equipment, means and methods of work. It's fascinating to me to get to see and learn how other regions and countries in the world tackle basically the same problem. David427, you might try keeping your fingers still and eyes open once in a while, you might learn something.

well said CM1995:thumbsup

Well, some of us are descended from farm stock, survivors of the depression and the folk that did without and got things done with what they had while sending massive volumes of the latest and greatest technology to Europe and the Pacific so the fighting forces could win the big one. I'm not trying to throw gas on the fire of a disagreement, there will always be newer, better (maybe), faster ways to do most any job. If you have a need or tend to specialize in a certain type of work, or have a rental company close to hand that will give you a good rate on the special machine or attachment you want to use, then go for it. Most of the small contractors tend to make do with what equipment they have on short jobs, mostly because it's either paid for, or the payment needs to be made on it.

On a personal note back when I was head mechanic for a construction outfit I supervised several mechanics and a couple other guys. They seldom did things the way I would have, but as long as the job got done correctly and safely I rarely intervened. If they asked for it, or I thought they needed it, I would advise or suggest. In the process generally we both would learn something.

You don't always need the latest and greatest whiz bang gadget to get work done, if that's your thing and you can afford it great, but don't look down your nose on somebody doing things a different way, they might just know something you don't, yet.

Let's all have a beer and then go back to work on Monday :drinkup

 

[Aliate]

I will never own a pulverizer out of spite for this guy.

 

[brianbulldozer]

Brian where exactly are you located? This is in Tacoma..

Aliate,
I'm in the Tacoma area (suburbs). Let us know how it turns out, I think you will do fine.

Brian

 

[Aliate]

I'm going to submit my bid on Monday, they may just be price shopping so who knows... either way its good bidding experience for me.

 

[Scrub Puller]

Yair . . . Well now that's all over . . . (big grin)

Actually I found the discussion quite interesting as a couple of years back I saw what I now know to be a "concrete densifier" working while on a visit to the big smoke.

I remarked at the time to another old bush bloke who was watching from our hi-rise balcony that the whole operation looked like expensive bull****e and the machine should have been at the other end of the operation and processing the material before or went into a crusher or landfill.

They were cracking it out in bloody great slabs and then munching and he reckoned it was 'like cutting mill-logs into firewood' which sort of ties in with Landclearers observation of breaking large easily handled pieces smaller and getting them mixed up with dirt and what all.

I think some folks get carried away with technology.

The dirt and concrete are the same as they were fifty years ago.

Only the machinery and methods have changed and, from what I see of failing pavement, concrete cancer, mismatch of machinery and poor co-ordination on jobsites I think some folks have lost the plot on the altar of "technology".

Cheers.

 

[Aliate]

Well said

 

[CM1995]

Ok Aliate let's get this thread back on track and let's see if you can win this job.

Do you have any more questions before tomorrow?

 

[JNB]

I don't know how deep you dug to check the thickness of the concrete, but I'd verify that the smallish footing aren't just overpour. Man, they seem small.

 

[Aliate]

They were really square and I was able to get under them with a shovel.

CM,

Containers for me are going to be around 400 - 500 a can, which is way more expensive than hiring trucks, but I just figure I'm going to bid it using cans and make that decision later. Otherwise I think I'm good to go, dump is 15 min away and $10/ton, wouldn't be a factor if I were to use cans, and the cans are easier to load... just thinking out loud.

 

[CM1995]

Go with what's cheaper for this project, your competition is.

I don't know if it's available but I hired roll-offs by the hour and had them haul to a specific dump that charged by the load. At $10 a ton and 15 min away, it's going to be hard to beat hiring trucks.

 

[Wrecker96]

The way we would do it is dig around the footing then drop a wrecking ball on it into sections,proably like 5 foot sections and do a little clean up but we would use a 225

 

[Georgia Iron]

Once again why? There is no reason to complicate this job with "new fangled work tools" as you call them. A 25 ton hoe will take care of this project with the size of the footings. Concrete performs great in compression, very weak in tension.:cool2



Depends on the job, accessibility, location to disposal site, etc. My first choice is 20's, as one truck can service two or three cans depending on haul distance, add another roll off if the haul distance is greater. No time wasted loading dumps as you can always have a loaded can waiting on the roll off. However, it depends on the individual site. Hauled a lot of concrete in tandems and tri-axles as well.



I demo'd one several years back, for the price and the fact I didn't see the benefit of the attachment for the types of demo I perform, decided against purchasing one. We do residential and light commercial demo, no industrial or heavier structures as I primarily do site construction.

Anytime one can remove large sections of concrete and load them out it's always faster and cheaper to do it that way. That's why I didn't see the benefit of the pulverizer. The project I demo'd it on involved removing 6" concrete pavement and a small retaining wall. I had the slabs up and loaded out while the pulverizer was munching, leaving further debris to clean up. They have their place no doubt but not for what I do or for the project Aliate is bidding.

Reminds of a job we did 6 years ago for a fast casual restaurant. The existing building was demo'd to the outside walls, slab and roof because if they took the entire structure down, the set backs wouldn't be grandfathered in and the building would have set farther from the HWY. They originally planned on keeping the building slab but decided early on that it wouldn't be feasible with all the new plumbing and electrical underground that was needed, plus the fact the finish floor was going to be the polished concrete slab. The slab was around 2K sf.

I knew how the GC expected it to be done and I bid it that way - with jackhammers and a lot of manual labor. The super was worried this CO was going to affect the schedule, I told him don't worry we'll have it done in a day. In which he said - "No way".

Showed up that morning and the first thing we did was strip the sheathing and remove the studs on an outside wall in order to get an 8' opening. The building was trussed front to back with columns in the middle, so the side walls were non-load bearing. Had a slab saw come in and cut the floor into 4x4 pieces. Put the mini-ex inside taking the slabs up and ol' Blue (Gradall 536) with the boom shot through the hole. Loaded the slabs onto the forks and then loaded them into a tri-axle with high lift gate. Finished the job in the early afternoon and the super was shocked.

I bid the job with jackhammers and laborers as that's the price they were expecting, however I knew how to do it otherwise. In the end everyone was happy, bank account a little fatter and the schedule stayed on track.

This sounds like how I remove concrete. Good idea taking it up like that.

It appears Nebraska is a honey hole if you are competitive with a 225 and a ball...

 

[movindirt]

Whats wrong with using a 225?
