10" concrete slab or is it? 3

[jechols]

We have a project with an elevated 10" concrete slab. Before the pour the contractor put the reinforcing in on chairs then a layer of 1" conduits side by side and then a layer of 2" conduits side by side with no room for concrete to get to the bottom of the slab not mention the area of concrete being displaced. The slab has deflected and in some places the little bit of concrete that made it to the bottom of the slab is just falling off. Does anyone think there is any alternative but to remove all the concrete in the affected areas and start over. I personally think the contractor should of known better than to do this.

It could be JAE. They might class it under Section id10t. That just goes to show you that fool-proof is a relative term.

Perhaps that should be in the building code: lack-of-sense load increase factor assigned to the contractor based on past performance.
