Hi all.

Hi Azn.

Most projects with piles use a pile rig to bore the holes, drop in rebar cages, and pour concrete to a few feet above where the bottom of the raft will be. They then excavate, exposing the pile caps that they then break with jack hammers leaving the rebar sticking up to be tied in with the raft rebar.

Point is, after all that, some of the pile rebars are bent. Most of the time they do straighten them somewhat but only to make it easier to tie to the new rabar for the raft.

We know they used unconventional proceedures on this project. They poured the pile concrete to the level they needed, leaving the rebar sticking up, no pile cap breaking needed. They did, however, cover the piles for a time with dirt so they could move equipment around freely. They then had to remove the dirt from around the rebar causing the bending.

This amount of bending is among some of the worst I've seen but it really doesn't matter - it will still do its job of tieing the piles to the raft. They may straighten them some anyway.

Great updates Konta - thanks for posting.


Ray.

I think the new steel frames are used to fix the rebars.Is that right?

That was my first thought I saw them. The slab will be so extreme thick so they surely need some way of tying all the rebars vertically.

Yes, they will tie the rebar to those steel poles.

Hi all.

The top of the raft will be the floor of level B5. If we add 6 inches of concrete above the top of those rebar boxes, level B5 will be the same (short) height as B4. The fact that they did the rebar boxes seperately from the main rebar for the raft suggests the raft may not be as high as those boxes though but I'm sure it will be close.

The rebar is about a half a meter thick right now. The pile rebar was sticking up about 1.5 to 1.7 meters above the blinding. I think they will continue to lay rebar at least untill the pile rebar is covered. The BK slab is 3.7 meters thick and the ST slab is 6 meters thick ! This one will be in the ballpark as well.

I digress ... The frames are lined up. Perhaps they are used to support some sort of piping ?? As with the frames, that would be a little out of the ordinary but that is the MO of this project anyway - that's what makes this one so interesting.

Can't wait until they start pouring concrete. It will take hundreds of trucks loads.

Sorry Fury, you're a bit wrong. In every rafts you need rebar at the bottom for tensile loads and rebar at the top of the raft for compression loads. When your raft is not very thick, these layers do meet or overlap. When your raft is several meters thick you need these distance holders you see in the pics above. Their main purpose is to offer a base to put the upper layers of rebar on. In between there is only concrete. Filling all this up with steel would be way too expensive.

Thanks Gol.
I looked closer at some of pics I have of raft prep.
I stand corrected.

How come some of the metal bars sticking up are curved?
