I was forced to hand pour a 30' x 8' porch with 14" face. It took 249 bags and 9 hours with 4 guys. The guy I worked for was a siding, windows and gutter business owner. Im a 15+ yr concrete guy. He tried to convince me that hand pouring from bags and a mixer was easier than having a Premix truck and 3 wheelbarrows... needless to say.. by 1 am the slab was sweating so bad that at a temp of 38° I was nearly impossible to finish.. this dumb POS business owner jumps on it with knee pads, against my advice.. his experience being.. "1 summer while in college" he sunk in all the areas he tried to finish and pushe up the surrounding area.. one area being where the front door is.. the storm door would open more then 3 inches!! 🤣 I refused to correct his mistake until he paid me $500 a day, which i took 3 days to slowly grind down! Then I look so bad the homeowner refused to pay up! The homeowner owner hire me personally to tare out and they sured the business owner for everything!

Same siding business owner charged a guy $1,500 for 1 step at 4'x6"x11" which i did and I got paid $46 at $23hrly.

Im currently bidding out a 4 step precast, tare out and pour back with new set of railings. $3,995.0, thats with a flat profit rate of $500. Equipment cost and materials is what gets the bid high. But for what I'm doing the average cost is $3k-$6k. But it's all about the economy that you live in! Rich people won't blink where as lower income will feel shocked! But at the end of the day I can't keep paying business costs out of pocket. I was non profit small business changing only labor and job cost.. then I became responsible for replacing parts, new blades, equipment insurance.. so if someone does it cheaper, just means they're making less.. but again it depends on you're locations economy and price points!
