New DIY sidewalk - looking for basic pointers

[cgilley]

I happen to live in a county with the highest per capita income in the state. Consequently, quotes for projects are stupid silly. The main rule seems to be to throw a number against the wall and see if it sticks. Anyway, so I need a front side walk. Shape is simple and total area will be about 100 sq. ft. making it about 1.25 yards. In my research, I've crossed the line for self mixing, so I am looking at a short load to be delivered (getting some quotes now). With that said, I have some big picture questions of the overall process:

1. How much do you normally add for just that little bit extra, 10%?
2. I've already figured out that when the truck gets there is very TBD. But when it does show up, I really don't want it on my driveway right? Empty they are around 25,000 lbs so 1.25 yards adds another 5000 lbs. The walk is about 60' from the residential street. So, if I don't allow the truck to backup on the driveway....
3. It's either a pump truck (seems overkill for my job) or renting a concrete buggy. I'm guessing 5 trips from truck to project area. Does the driver just wait for the project to complete concrete movement? Is this factored into the delivery fee?
4. Assuming it's just my load on the truck, what happens to any leftovers if the sidewalk cannot use it? I really don't want a pile of concrete in my front yard, especially if I paid for 1.25 yards and the truck happens to have a little extra...

Appreciate the advice.

Good questions. I’d order about 5–10% extra, use a buggy for the 60 ft run and expect a tight unload window. Any leftover usually gets dumped on a prepared spot or formed into a small pad.

Thank you sir. I watched a couple of videos of crews working with a truck, and it seemed like they were hustling.
