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 24EA0027 and 22EA0241 have near-identical descriptions about 833 m apart (funding years 2022, 2024; ₱18.21M, ₱19.60M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or expansion of the first, or covers additional works not specified in the title.

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 the only difference being the word 'Structure' in the second title, which is not a distinguishing marker per the rule. Both are in the same municipality, refer to 'Santol Flood Control' in Boac, Marinduque, and are about 833 meters apart. There are no phase, package, section, or place markers that distinguish them as separate works. The evidence is complete and meets the rule's criteria for publishing.
