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 22IG0037 and 24IG0028 have near-identical descriptions about 533 m apart (funding years 2022, 2024; ₱95.54M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or extension of the previous year's project, but this is not labeled in the title.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have identical titles with no distinguishing markers, are located within the same municipality, and are only 533 meters apart. The only difference is the funding year and contractor. This fits the rule's criteria for a potentially duplicated or overlapping project, as there is no phase, section, or location marker to distinguish them as separate works.
