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 23FM0007 and 24FM0034 have near-identical descriptions about 96 m apart (funding years 2023, 2024; ₱23.52M, ₱49.00M). Worth checking whether they cover the same works. This may be a continuation or extension of the previous year's flood mitigation works.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only minor wording differences ("at" vs comma, "Brgy." vs "Barangay"), and no distinguishing markers such as phase, package, or different locations. The projects are about 96 meters apart, in the same barangay and river section, and funded in consecutive years. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations (such as a continuation or extension of works) are plausible but do not block publication.
