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 24HO0090 and 24HO0091 have near-identical descriptions about 170 m apart (funding year 2024; ₱96.50M, ₱96.50M). Worth checking whether they cover the same works. It is possible that the two contracts cover adjacent or continuous sections of the same revetment wall, but this is not clearly labeled in the titles.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have near-identical titles, both refer to the same sitios and barangay, and are only 170 meters apart. There are no distinguishing markers (such as different phases, sections, or additional place names) in either title. The only difference is the order of the sitios in the title, which does not indicate different works. This fits the rule's criteria for a potentially duplicate or overlapping project.
