Pre-cast concrete double-tee details

Pre-cast concrete double-tee details

Pre-cast concrete double-tee details

(OP)
I am the engineer of record for a residential apartment building that will utilize a precast double-tee slab and inverted-tee girder system for the transfer slab over a 1st floor parking garage (I know this is unusual, but the precast engineer has convinced the developer it's worth his while). The precast designer will be preparing detailed design documents for the precast system, and I only need to show the precast portion conceptually on my construction documents. This is my firm's first foray into double-tee construction and we don't have any details in our CAD library. I am looking for downloadable CAD details I can start with to speed up the drafting process. I only need conceptual precast details since I just need to show how the other structural systems connect to the precast. I spent some time on google and found a number of hollow-core plank details but very few double-tee details. The best resource I have found is this:

Anyone else have any suggestions?

Thanks!

RE: Pre-cast concrete double-tee details

The Double Tee To Inverted Tee Beam Connection-B is very similar to the detail we use for underground parking garages on apartment buildings.  Quite often it is a design with double tees for a center span supporting the hallway walls above and hollow-core planks for the outside spans.
