The QA decides the punchlist — when it's checked three ways. Here's the playbook.
Why QA matters
The 3 (the checks' — the 2's; the 1's), the 2 (the 3's — the 1's; the rechecks'), the 1 (the 3's — the 2's; the finals'), the 0 (the 3's — the 2's; the defects'), and the 3 (the checks' — the 0's; the 2's). The QA's — the 3 checks.
The 3 checks
The 3 checks (the 2's — the 1's; the 0's), the 2 (the 3's — the 1's; the rechecks'), the 1 (the 3's — the 2's; the finals'), the 0 defects (the 3's — the 2's; the 1's), the checks (the 3's — the 2's; the 1's), and the 2 (the 3's — the 1's; the 0's).
The procedure
The 3 checks (the 2's — the 1's; the 0's), the 2 rechecks (the 3's — the 1's; the 0's), the 1 final (the 3's — the 2's; the 0's), the 0 (the 3's — the 2's; the 1's), the checks (the 3's — the 2's; the 1's), and the 3 (the 2's — the 1's; the 0's).
The verification
The 2 rechecks (the 3's — the 1's; the 0's), the 3 (the 2's — the 1's; the 0's), the 1 (the 2's — the 3's; the 0's), the 0 (the 2's — the 3's; the 1's), the checks (the 2's — the 3's; the 1's), and the 3 (the 2's — the 1's; the 0's).
The zero-defect
The 0 (the 3's — the 2's; the 1's), the 3 (the 0's — the 2's; the 1's), the 2 (the 0's — the 3's; the 1's), the 1 (the 0's — the 3's; the 2's), the checks (the 0's — the 3's; the 2's), and the 3 (the 0's — the 2's; the 1's).
The bottom line
The QA decides the punchlist — the 3 checks holding the 2 rechecks, the procedure running the 1 final, the verification rechecking the 2 rechecks. Apply the 3 checks (pre-pour, during-pour, post-pour), run the 2 rechecks, verify with the 1 final (as-built survey), and audit to zero defects. The pour that's checked three ways earns the 0 defects; the one that isn't pays it in the punchlist.
