Concrete Vaults
Concrete Vaults
(OP)
We are designing a 20' and 8' stormwater detention vault. Is it customary to allow the contractor to determine if its cast-in-place or not.
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

I have seen our company have a structural engineer design the rebar and concrete for the vault but I think this is useless as long as its spec'd out and you require a submittal in your spec.
Thoughts?

Designer in the side of the contractor should decide how to build. And if it is able to build with precast elements he shouldn't be afraid to use it.

Becasue of the high cost pre-cast is not a prefered options in mosst cases.

i really dont think as engineers we need to decide on alternatives methods to our entire design up front. Is that what you mean?
For vaults, if they design is for pre-cast and they decided to go to cast-in-place who comes up with a rebar and concrete design?
RE: Concrete Vaults
I have seen my company have our structural engineer prepare a complete vault design with rebar which I think is completely unneccessary if you just spec it out appropriately.
Any thoughts on this?

1. conditions (static, environmental)
2. schedule
3. cost (money which I have got or which I could get from investor in the case when I will propose solution other than the specified)
3. process technology (it's very important as well)
I'm not designer, and that's why before I'll decide to change design / choice option I ask designer. The designer - who I work with - not should but have to tell me 'You can, we can try to do it in THIS way and then we will estimate how the cost of that solution is' or 'You can't / mustn't, becouse...'
Summaring... ask vaults designer or concrete construction designer.
