Where each walk sits in the schedule
- Terrazzo flooring rough-in inspection checklistrough-in
- After the slab is placed and cured and before the underbed goes down, early enough that a high spot or a live crack can still be dealt with under the system rather than through it. Run by: The terrazzo mechanic setting strips ahead of placement, with the GC's superintendent releasing the slab.
- Terrazzo flooring final inspection checklistfinal
- After grinding, grouting and final polish and before floor protection goes down and adjacent trades traffic the surface. Run by: The GC's superintendent with the terrazzo foreman, walking the finished floor before it's protected for turnover.

- During closeout after protection comes up, once other trades have finished and any slab movement has had time to show. Run by: The terrazzo foreman on a callback, or the GC's superintendent closing flooring punch before turnover.
What most often sends terrazzo flooring work back
- Divider strips laid to a convenient line instead of the control and construction joints, so slab movement cracks the field.
- Crack-suppression membrane skipped or stopped short over an active joint the terrazzo then telegraphs.
- Underbed depth pinched thin at a high spot in the slab, leaving too little matrix to grind flat.
- Pinholes from the grout coat never filled, showing up as a rash of dark specks once the floor is sealed.
- Dull spots left where the polish sequence was cut short, obvious against the sheen under corridor lighting.
- Sealer applied over a floor that wasn't fully clean, locking in haze and grinding dust.
- A crack telegraphing up through the field away from a divider strip, signed off as cosmetic when the joint below is moving.
- A loose or drummy spot tapped and noted but never cut out and re-poured before the area is released.
