Indicator C3 — Duplicate or Near-Duplicate Projects

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

Duplicate or Near-Duplicate Projects

Very similar descriptions within ~100m or identical coordinates across contracts/years.

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

Indicator: contracts 24OC0045 and 23OC0094 have near-identical descriptions about 588 m apart (funding years 2023, 2024; ₱29.39M, ₱19.79M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or that different sections of the same creek were rehabilitated in consecutive years.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, with only minor spelling/abbreviation differences (Barangay/Brgy., B.F./BF, Metro Manila omitted in one), and both refer to the same creek tributary and barangay in Parañaque City. There are no distinguishing markers such as different phases, packages, sections, or sites. The projects are about 588 meters apart, which is above the strict 100m threshold, but the rule is for near-duplicates within the same municipality, and the titles do not indicate different works. The evidence is complete and checkable.
