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 MEGAPOLITAN BUILDERS AND CONST SUPPLY by the same office started within 18 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 6 in the same municipality. It is possible these are separate phases or segments of a larger flood control program scheduled and funded in parallel.

This is a textbook C5 case: six contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, all in the same municipality, and started within 18 days. The titles refer to similar types of flood control works in closely related locations (same creeks, bridges, barangays), and the code has already confirmed the cluster math and thresholds. There is no evidence of a data artifact or that these are unrelated works; the pattern is genuinely unusual and worth public attention.
