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 22LE0058 and 22LE0042 have near-identical descriptions about 50 m apart (funding year 2022; ₱14.84M, ₱14.70M). Worth checking whether they cover the same works. It is possible these are two separate but adjacent slope protection structures in the same barangay.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, both refer to slope protection works at (Brgy./Barangay) Pangian, Malita, Davao Occidental, with no distinguishing phase, section, or site markers. The only differences are generic (Structure/none, Barangay/Brgy.), which are not distinguishing per the rules. Both are in the same funding year, about 50 meters apart, and the amounts are similar. Innocent explanations are possible (e.g., two adjacent but separate structures), but the evidence is sufficient and the pattern is genuinely unusual.
