Indicator C5 — Pattern Consistent with Contract Splitting

AI-verified / Na-verify ng AI Data as of October 21, 2026

Pattern Consistent with Contract Splitting

Multiple similar contracts to the same contractor/DEO just under a threshold in a short window.

This is a statistical anomaly or indicator worth examining — not proof of wrongdoing, fraud, or corruption against any person.

Indicator: 6 contracts awarded to PHILSOUTH BUILDERS INC FORMERLY:PHILSOUTH BUILDERS by the same office started within 31 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 4 in the same municipality. It is possible that these are separate river control projects for different rivers or locations within the same municipalities, which may have been planned together for efficiency.

Prompt: v4

Checked: October 22, 2026

This is a textbook C5 indicator: six contracts, all just under the ₱50M threshold, awarded to the same contractor and DEO within 31 days, with four in the same municipality. The titles are similar but name different rivers or locations, which is expected for C5 (the rule is about clusters in one municipality, not duplicate works). There is no evidence of a data artifact or false positive.
