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 24FG0051 and 23FG0041 have near-identical descriptions about 437 m apart (funding years 2023, 2024; ₱49.00M, ₱47.77M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the previous year's project.

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 (no phase, package, section, or different place names), are located within the same municipality, and are only 437 meters apart. Both are for 'Construction of Flood Mitigation Structure along Burabod Creek, Tigaon, Camarines Sur' and funded in consecutive years by the same contractor. This fits the rule's criteria for a potentially duplicate or overlapping project. Innocent explanations (such as a continuation or expansion of works) are plausible but do not negate the anomaly.
