• Frequency: 1 set (3 cylinders) per 50 cu.m. or per day's pour, whichever yields more specimens.
• Acceptance Criteria:
  1. Incorrect Sampling Frequency: Many engineers fail to remember that for soil embankment, the frequency is one compaction test per 200 cubic meters, but for select materials, it is per 150 cubic meters.
  2. Neglecting the "Abrasione" Test (Los Angeles): The allowable abrasion loss for coarse aggregate used in pavement wearing course is maximum 30% (not 40% as in some older manuals).
  3. Misapplication of the "Job Mix Formula" (JMF): The Materials Engineer must verify that the asphalt plant’s JMF does not deviate by more than ±0.3% on asphalt content and ±5% on aggregate gradation from the design JMF.
  4. Fake Certificates: The updated reviewer emphasizes cross-checking mill test certificates for steel and cement with the Bureau of Philippine Standards (BPS) online database.
• No pending administrative case with the DPWH or PRC.
