Worried about my slab pour

[motormitch]

My builder had the foundation for my slab formed in, sandbagged perimeter and the rough plumbing installed with plans to pour the weekend. The foundation is on a slope and is 7 feet elevated on the back wall and one side wall. We just had a VERY heavy rain and when I checked the job site the sand bags had partially collapsed toward the form walls. In some places is actually sifts all the way over and actually touched. There are large sections where the sandbagged edge will clearly have to be completely redone. First the builder believed that we would wait a few days to dry out and then rebag. This would impact the pour about 1 week. Then he meet with the foundation engineer and here is what he just emailed me.

------------------------------------------------------------------------
After consulting with Roberto at CRI , two other concrete subs and Baldi (this afternoon) we need everything to dry out before continuing and that once the bag form walls are repaired half way we will pour concrete up to that point called a (weather stop pour) which will be inspected by Matt from CRI so we are pushing for a partial pour this Thursday coming and the final top out pour Monday the 15Th leaving 2 weeks to cure we also will the back parking poured and the front formed and graded before bldg arrives
-------------------------------------------------------------------------

I can't seem to find anything about a weather stop pour except for very cold weather or pouring in a heavy rain. Does this make sense or should I insist on a different plan. This is a big building (to me) 70'x55' It is also a post tension foundation.

Guide me oh great ones who have gone before me...

Sounds like good advice. If there is more weather comming you might want to cover as much as you can so you don't have another delay.

I don't know much about concrete but why can't they not do it all at once? Is there a reason they can't wait the week and fix it up? You may want to PM LLWillysfan for advice. He is a concrete expert and if you have not see his thread in the Garage Gallery you may want to take a peek.

because you do not have compaction with all the excess water in the soil

First, you need to hear from the experts which is not me.

My concern is that your contractor may be schedule driven, as opposed to optimum job driven. Time is money, wants to keep crew engaged, etc.

You too are certainly concerned about schedule but I suspect not to the level of compromising the job. Concrete is a one time deal that is not easily undone so I would make sure that what you are getting abides by the experts guidelines that are on this board.
