new construction也是builder来管sub contructor吧,自己监工有用么?

If you are knowledgeable about construction, very 有用, you can see the quality of the work (or sub-contractor skill) Passing city or county inspection does not mean it is quality work. If not, check for beer cans, I have even seen drunk worker walking on the roof sometime.

Not sure where you are building or what type of foundation you have, mainly spread footing foundations, mat-slab foundations, and slab-on-grade foundations are used in most parts of US. Make sure rebar is in the middle (not too low), make sure they do not pour when is too cold, make sure they water it for at least 2 or 3 days. Also take a few sample from each batch of concrete, so if you are paying for 4500 psi mix, and one of the sample turns out to be only 4000psi, they need to redo the whole

Are u buying the new construction from builder or you own the lot before the construction started? Thanks a lot.
Most place say 40 F. I like it to be at least 50F. If poured at temp below 40F strength of the concrete is reduced by at least 50%. It may not have any problems for a few years, but you will see lots cracking down the road.
