Application of Polyprime.
Block Work Quality
As a QC Engineer during site visit I do observed these kind of non-conformance many time the root cause analysis is too difficult for me, all the masons are trained procedure briefing has been given to them in their speaking language I came to the conclusion its lack of skilled mason, I will escalate my findings to construction team we need experienced masons.
Cavity Wall tie not provided in alternate layer.
Fair face of block not provided at door.
Block not stacked properly.
Lines and Level not monitor properly.
Block not fixed properly and top layer placed.
Stretcher Bond not followed at junction.
Mortar thickness not within tolerance.
Block not placed properly at junction.
Manual cut block used resulting uneven mortar joints.
Curing in block-work not monitored.
Line and Level of joint not monitor properly.
Block Work
As a QC engineer during the site visit following Non-Conformance observed in block work and issued to the site team now site team need to close out the nonconformance's prior to further work at the locations.
Which involves the physical rectification of block-wall along with document confirming that a training has been provided to the masons and the same issue will not be repeated in future.
When multiple minors NCR issued for the same issue then this can be considered a "systemic failure." it will affect the reputation of the subcontractor which can terminate their contract with us.

Prior to Backfilling
Back-filling around the structure is going to start, as a QC Engineer I will send the following comments to site team and ask for their actions prior to backfilling.
1. Tie rod holes to be filled.
2. The structure below ground level to be protected.(C-4 Paint and Polyethylene sheet)
3. Waste concrete, Binding Wire, Nails, Wooden Ply, Polythene etc to be removed.
Tie rod holes to be filled and structure to be protected.

Surface Preparation
Why site engineer's don't include surface preparation in their activity?
Preparation for Light weight concrete work is going on in checklist items surface preparation always get ignored
site team will be notified to rectify following comments prior to screeding.
Tie rod holes to be filled.
Defect in concrete to be repaired.
Tie rod holes to be filled.
Debris to be removed.
Parapet columns to be casted prior to screed.
