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 24IA0032 and 23IA0036 have near-identical descriptions about 871 m apart (funding years 2023, 2024; ₱9.79M, ₱4.79M). Worth checking whether they cover the same works. It is possible that these are sequential phases or extensions of the same flood control project, but the titles do not specify this.

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 both in Barangay Agpangi, Naval, Biliran, and are funded in consecutive years. The distance between them (871 m) is above the 100 m threshold, but the titles do not specify different sites or segments, so it is plausible these are overlapping or repeated works. All necessary records and URLs are present.
