Help me identify this floor plate system?
(OP)
I am currently tasked with doing design checks on an existing vacant shell building, which is to be fit out as a retail store. The single storey building is roughly 5 months old but there are no available structural as-built or design drawings available.
We have prepared a spec for some investigative work - exposing slab and column reinforcement, excavation to measure foundations, concrete core strength test etc. I have not visited the site yet, but from the attached photo, can anyone tell me what this floor plate system is? It looks like a series of band beams spanning across the columns (grid is 10.2m x 9.5m) with a 2 way slab in between, same depth as the bands. Or is a flat slab system? the orange rectangular strips on the under side of the slab are confusing me though.
Is there a possibility it could be pre-stressed?
Any advice would be much appreciated.
Thanks

The big question is where is this building located that a 5 month old building has no existing design drawings available?

avscorreia - can you explain how the waffle slab works with the masonary units. is the the slab cast insitu around the units, with the bottom reinforcement in between the units spanning in the same direction?

FERCA has been selling slab masonry units for a long time. You can check their system and a typical slab section at the following link:

Similar to a waffle slab with bricks instead of voids. 2 way slab based on those dimensions, looks like middle strip would be lighter and have a reduced moment of inertia than a conventional solid slab. This seems to be a popular form of construction in continental Europe, particularly for residential buildings.

your thoughts?
SteelPE - agree with your concerns. initially we were promised full detailed drgs and calcs from the building owner. my client is only leasing the building for a 10 year period so the building owner should have been responsible for providing this info.
