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: 5 contracts awarded to JELSIE CONST & SUPPLY by the same office started within 1 days, each between ₱42.5M and ₱50M (just under the ₱50M threshold), with 5 in the same municipality. It is common for large cities to have multiple flood control projects in different locations awarded around the same time.

This is a textbook C5 case: five contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 1 day, and all in the same municipality. The titles refer to similar types of flood control works (pumping stations, retarding basin, booster pumps) at different esteros and barangays within Manila, which is expected for C5 (the rule is about clusters in one municipality, not duplicate works). There is no data artifact or false positive; the evidence is complete and clear.
