top down construction
(OP)
Anyone know of any good references or rather any reference on top down construction?
I've found a few articles and have some different ideas about how to go about it, but want to know if there were any other references.
Thanks

I know of no references other than decriptions for particular buildings.

he means "top down construction" this is where you construct basements from ground level down. First you construct diaphragm walls and bored piles, then you excavate. When you reach the level of the first basement level floor you cast the slab, this struts the diaphragm walls. Then you lift an excavator through a hole in the cast floor slab to excavate for the next level down. Work continues until you reach the lowest level.
There are advantages, in particular that no struts, or at least reduced strutting is required. Disadvantages include the need to provide ventilation for the diesel engined excavators and of course spoil removal is slow by crane and skip.

In keeping with the same discussion, has anyone constructed a basement using steel sheet piles and left them exposed as the basement walls. What are the fireproofing implications if any thay you may have run across. From a structural standpoint I don't see a problem if the walls are designed, I can only think of fire rating being a problem.
I'm throwing the idea out since sheeting will be cheaper than a slurry wall.
I know that local jurisidictions will have a say in all this, but wanted to know if anyone has successfully used this option.
