Mixed-use
One project, several buildings' worth of standards.
Retail and parking on a concrete podium, apartments framed above it. Mixed-use stacks occupancy types and phases in a single project, each with its own separation ratings and its own inspectors. RTI keeps every one of them on the same record so nothing falls between the trades.

What gets in the way, and what RTI does about it
Today
The podium deck separates apartments from the retail below, but the waterproofing is buried under topping before anyone documents it.
With RTI
The deck is tagged bay by bay and the membrane submission cannot close until the drain, flashing and termination photos are attached, so the proof exists before the topping goes down.
Today
Three occupancy types mean three sets of rules and three inspectors, and the separation between them is where things fall through the cracks.
With RTI
Each occupancy-separation assembly carries its own tag and checklist, so the rated firestop between parking, retail and residential is evidenced at the assembly, not assumed at the interface.
Today
The retail wants to open before the residential floors top out, and pulling one clean closeout out of a shared pile is a fight.
With RTI
Each phase is its own set of tags on the review board, so the retail exports and hands over on its own timeline while the residential tags stay open above it.
Questions mixed-use ask
- The podium is occupied retail with apartments above. How is the deck waterproofing proven?
- The podium-deck membrane is tagged bay by bay, and each submission requires the photos of the membrane at drains, flashing and terminations before it can close. The water separating residents above from retail below is documented while it is exposed, not after the topping slab covers it.
- Different occupancies mean different separation ratings. Can one system hold all of them?
- Yes. Each occupancy-separation and horizontal-assembly firestop location carries its own tag and checklist, so the rated separation between parking, retail and residential is evidenced at the assembly. Build the checklist once and bind it wherever that rating repeats.
- The retail opens while the residential floors are still going up. Does the record handle phasing?
- It does. Each phase is its own set of tags and submissions on the review board, so the retail closeout package exports and hands over on its own timeline while the residential tags stay open above, all on one project record.
