@XR250 - lol, hopefully not in this case! @Bridgesmith - unfortunately my route to the stones runs perpendicular to the beams so I won't be able to utilize them as a path. Your point about damage vs failure is a good one, especially since this slab will be removed anyway. @enable -...

@enable - oh, there are definitely going to be many, many detailed qualifications on this one! Your comment about UDL vs discrete point loads gets to the heart of my questions. I know that when we lift something with a forklift almost all of the load is on those front tires. It becomes a...

@EZBuilding - No matter what process is used, each stone will be completely removed from the deck upon removal. There will not be any stacking on beams or anywhere else on the deck. At most we would have one machine and perhaps 6 people working on this deck (200' x 25') simultaneously. This is...

@Sliderule - I have located a forklift that weighs 8000 pounds and can lift up to 5000 pounds which would cover an area of about 16.5 sf. Alternatively, I have also located a small telehandler that weighs 11,000 pounds and occupies 44 SF. So it's heavier but the weight is spread out more.

I wouldn't be responsible for the demolition of the slab. I just need to remove some stones, and then get them out of the area. The GC has its own headaches to worry about with the removal of the slab. What I am hearing is that I need to proceed cautiously, probably carry a fairly significant...

Appreciate the insights so far. I'm a contractor considering a bid for this project. The bid documents specify a 75 psf Live Load (LL) limit for the existing slab, but lack detailed information about its condition. Given that the slab is scheduled for removal, it's likely not in prime shape. My...

Unfortunately, I do not. I am a contractor who has received contradictory information elsewhere and was hoping that this forum might be able to shed some light on factors that are more or less relevant.

I need advice on a specific load calculation for a project. Our task involves using a forklift (8000 pounds) on a 10-inch concrete deck, designed for a maximum live load of 75 psf. The deck is supported by 24-inch wide by 30-inch deep concrete beams, spaced 18 feet 8 inches apart, and foundation...
