Indicator C5 — Contract Splitting Pattern

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

Contract Splitting Pattern

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 that these are separate projects planned for different locations or phases within the same municipality.

Checked: October 22, 2026

This is a textbook C5 indicator: six contracts, all just under the ₱50M threshold, awarded to the same contractor by the same DEO, started within 18 days, and all in the same municipality. The titles refer to similar types of flood control works in Batac City, with some distinguishing by phase or location, but C5 does not require title overlap or reject for different sites. The evidence is complete and the public text is clear.
