All,
I just wrapped up Alan’s class on the new Smart Stakeout command — really impressive stuff. That said, in my 15+ years doing construction staking here in Indiana, I’ve never seen curb inlets staked the way he showed in the video with multiple offset lines.
My usual approach is pretty simple: one lath at the CL of the structure (back of curb), then either a 15’ offset with a tacked hub in both directions along the back of curb, or a 15’ and 30’ offset if I expect the closer one to get knocked out during pipe installation.
I’m curious — how are curb inlets being staked in other states?

My Method of Staking
(UT/CA with mutliple companies here) they’re staked like that from my experience, then we’ll run a string between hubs, hang two plumbobs at the rear corners off the string and set the box.

(Michigan) To place the structure, I believe our field guy would typically stake two inline offsets (like your 15’ - 30’ in the same direction away from the structure) and then provided a cut/fill to rim and a cut to lowest invert on the nearest of the two offset stakes. Seems like they may have provided back of curb stakes w/ tacks to position castings as well.

The way I teach and stake structures is by first setting a lathe at the structure centerline. From there, I place hubs and tacks with lath at 10’ and 20’ offsets. Then provide two stakes at 10’ on each side of the structure, set 2’ back from the curb, so the crew can square the DI to the curb line.
