Thanks CM!
He replied, why are you even wasting your time, you must be really bored.
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.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.
Brian where exactly are you located? This is in Tacoma..
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.
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 225View attachment 123438
