We have been asked to concrete out a new livestock building about 50 meters long by 25 meters wide. Simple enough in principle except some passage ways are about 8" higher than the main floor level. Our intention is to pour all the main floor areas first, leaving out the passage ways. We will then stone up the passage ways to the floor level then pour the raised passage on top and slightly over lapping the floor. The shuttering for the main floor will be standard steel road forms pinned into the stone sub base. However, I am looking for a good method of shuttering and fixing the 8" high passage way. At the moment we are thinking of timber shuttering drilled and fixed into the cured concrete below. This would work but is very time consuming. Does any one have experience of this sort of thing and a better method than ours?

I have seen similar done for a 800m2 apple packing warehouse with 12" machinery and conveyor plinths running down the middle of it
(assume no cladding around edge of building so you can pour plinths off mixer wagon) set out forms for passageways first double stacked 8" on 8", high slump mix. Pour, strike forms
pour livestock bays afterwards. Again assume no cladding or some access so you can get pump probably 24/4 section plus groundline or even better 32/5 section off boom.
ok you don't have a form to tamp to but surely better than hilti-ing shutters close to the edge of the bays

make your shutter keeping the bottom wailing 20ml up from bottom of ply and place it where its going If you cut some rips of ply about 100 / 200 ml wide and 600 long you can nail these under the bottom wailing against the ply. nail the rips of ply which are attached now to bottom of shutter with hilti nails into the floor ( you can use 6/8 ml drill bit to make holes 40 / 50ml deep and fix them to the floor by wedging 2/3 wire nails in through the ply they will hold fast for what you want. ) that will brace the bottom. Now all you have to do is put struts from your soldiers and nail these to your rips of ply.
