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 23GH0049 and 24GH0043 have near-identical descriptions about 666 m apart (funding years 2023, 2024; ₱86.46M, ₱44.10M). Worth checking whether they cover the same works. It is possible that these are sequential or complementary projects addressing different aspects of flood management in the same barangay.

How this was checked

publish · confidence 0.95

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical, both referring to the construction of a flood-related structure in Barangay Natividad, Barotac Viejo, Iloilo, with only a minor difference in the use of 'mitigation' vs 'control'. There are no phase, package, section, or location markers distinguishing them, and both are at the same barangay. The projects are funded in consecutive years and are about 666 meters apart, which is within the range for possible duplicate or overlapping works. The evidence is complete and meets the rule's criteria.
