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 22OF0200 and 22OF0072 have near-identical descriptions about 1969 m apart (funding year 2022; ₱28.81M, ₱14.26M). Worth checking whether they cover the same works. These may refer to different flood control structures within the same barangay.

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, differing only in the pluralization of 'structure(s)', and both refer to 'Brgy. Baesa, Quezon City' with no distinguishing markers or different locations named. Both are in the same funding year, and the distance (1969 m) is well above the threshold for 'identical coordinates', but the rule is for near-duplicates within the same municipality. Innocent explanations are possible (e.g., separate structures in the same barangay), but the evidence is sufficient and the pattern is genuinely unusual.
