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 23LH0011 and 24LH0028 have near-identical descriptions at the same coordinates (funding years 2023, 2024; ₱71.93M, ₱68.51M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or necessary follow-up to the first project.

How this was checked

publish · confidence 0.98

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two contracts have near-identical titles, identical coordinates, and cover the same section of Mintal Creek in Davao City, with no distinguishing markers or place names that would indicate different works. The only difference is a minor parenthetical in the title, which does not indicate a different scope. Both contracts are for the same type of work, at the same location, by the same contractor, in consecutive years. This fits the rule's criteria for a potentially duplicated or repeated project.
