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 23LF0028 and 24LF0038 have near-identical descriptions about 817 m apart (funding years 2023, 2024; ₱96.50M, ₱48.25M). Worth checking whether they cover the same works. This may be a continuation or extension of the revetment project funded in a new year.

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 ('barangay' vs 'Brgy.' and 'Concrete' added), and both refer to the same river and barangay in the same municipality. The projects are about 817 meters apart and funded in consecutive years, with no distinguishing markers indicating different phases, segments, or locations. This fits the rule's criteria for a potentially overlapping or repeated project. Innocent explanations (such as a continuation or extension of the revetment) are plausible but do not preclude publishing.
