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 22HE0035 and 23HE0097 have near-identical descriptions about 2830 m apart (funding years 2022, 2023; ₱49.00M, ₱96.48M). Worth checking whether they cover the same works. It is possible that these are sequential or adjacent segments of a larger 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 in the same municipality, and are about 2.8 km apart. There is no evidence in the packet that they refer to different phases, sections, or locations within Talisay City. This fits the rule's criteria for a potentially duplicate or overlapping project, and the evidence is complete.
