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 23CE0006 and 24CE0196 have near-identical descriptions at the same coordinates (funding years 2023, 2024; ₱48.99M, ₱66.87M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or rehabilitation of the previous year's project at the same site.

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, refer to the same river and barangay, and are at exactly the same coordinates. There are no distinguishing markers such as different phases, sections, or locations. The only differences are minor wording (Barangay/Brgy., Structure/Structures, addition of 'Rehabilitation'), which are not distinguishing per the rules. This fits the C3 publish criteria for possible duplicate or overlapping works.
