如果以前设计的是什么都在一个平面上，现在需要把车库放低一尺，是不是得重新设计
地基啊，还是直接挖低地基了事。 | g*****9

I am assuming you are talking about spread footing foundation, right?

发帖数: 36306 | 3 not poured yet, since the construction manager said the gararge need to be
lowered to avoid steep drive way and we are having thunderstorms this week.
they already digged down the gararge part, but i am concerned if any
internal tension distribution change need to be taken into consideration,
say, re-design, which the builder won't be willing to do.
i am talking about slab on grade foundation.
now the floor should be about 2' above the gararge.

发帖数: 4125 | 4 Are you in CA or TX?
I am assuming you have no basement (not elevated structure slab), right ?
How thick a slab to they plan to pour?
What type of soil you have?
Did the builder tell you they will perform proper soil compaction prior to
pouring.
Are you building a ranch, 2 story or more?
Provide as much detail as you can, before I can give you an educated guess.

TX
slab, no basement
not sure, they never answer this question, so i just assume 4 to 6 inches
below the floor and 2' outside walls
no soil, only limestones, and they fill some gravel dirt.
they will compact the dirt, not sure how proper....
2-story
guess i am going to look for a resale and walk away when they complete to
qisitamen.

发帖数: 4125 | 6 Honestly I do not like slab foundation, if not done properly, it is very
hard to fix (jack up) if it begin to settle after some time.
But based on your answer it should be "ok" depending on your building plan
and how thick and what grade concrete they pour.
Here is two thingd you need to do:
1. make sure the rebar or mesh is the in the middle of the slab and properly
supported before they pour, or they need to use hook to pull them up to the
middle when pouring.
2. take several samples from each
