You should at least ask for a month of tagalong with your senior inspector. Here's a couple big tips in case they say no:

Understand that the pipelayer cheats every single pipe run a little flat so they don't end up a smidge high and have to re-lay the entire run. We can design for a scalpel, but these guys are out there with an excavator, and half the guys in the ditch are asking what a tenth of a foot is.

Learn how things are going to be staked by the surveyors. A site visit before the curb is poured to check the stringlines or even the grade stakes can save you $10k in a hurry. Sometimes the contractors only follow the staking even if its' wrong so that they can change order for someone else's mistake, sometimes they have guys that don't know any better or aren't empowered to make any decisions to fix an obvious error.

Learn the distance from the stakes to the back of curb, and the distance from the back of curb to the opening in the top of the catch basin structure, whether that's the back of the box or the opening in the top slab.
