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 23HO0096 and 23HO0225 have near-identical descriptions about 4507 m apart (funding year 2023; ₱26.46M, ₱26.46M). Worth checking whether they cover the same works. It is possible these are two separate drainage systems in different parts of Barangay Tunga.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The titles are near-identical, with only 'Barangay' vs 'Brgy.' as the difference, which is not a distinguishing marker per the rules. Both projects are in the same barangay, municipality, and year, with the same contractor and nearly identical costs. The distance between them (4507 m) is above the 100 m threshold, but the rule is about near-duplicate titles within the same municipality, and the evidence is complete. Innocent explanations (e.g., two separate drainage systems in the same barangay) are plausible but do not block publishing.
