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 22IK0033 and 23IK0017 have near-identical descriptions about 241 m apart (funding years 2022, 2023; ₱39.20M, ₱110.97M). Worth checking whether they cover the same works. It is possible that the second project is an extension or expansion of the first, or covers additional works along the river.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical and refer to the same general location (Silaga Bridge/Silaga River, Daang Maharlika, Barangay Tulay, Sta. Rita, Samar) with only minor wording differences (Brgy./Barangay, addition of 'River'). There are no phase, package, section, or station markers, and both projects are within 241 meters of each other. The only differences are the inclusion of 'River' in the second title and spelling variants, which are not distinguishing markers per the rule. This fits the criteria for a potentially duplicated or overlapping project worth public attention.
