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 24CF0003 and 23CF0038 have near-identical descriptions about 1343 m apart (funding years 2023, 2024; ₱85.11M, ₱77.20M). Worth checking whether they cover the same works. It is possible these are sequential phases or extensions of the same flood control project along the river.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two projects have identical titles with no distinguishing markers, are in the same barangay and municipality, and are funded in consecutive years by the same contractor. The only difference is the year and a 1.3 km distance, which is within the same river/barangay area and does not indicate a clearly different site or phase. Innocent explanations (e.g., continuation or extension of works) are plausible but do not negate the anomaly.
