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 24JH0034 and 23JH0003 have near-identical descriptions at the same coordinates (funding years 2023, 2024; ₱24.11M, ₱39.60M). Worth checking whether they cover the same works. It is possible that the second contract is a continuation or expansion of the first project.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

Both projects are at identical coordinates, in the same barangay and municipality, with near-identical titles and the same contractor. There are no distinguishing markers such as phase, package, or different sites. The only differences in the titles are 'Slope Protection' vs 'Flood Control Structure', which are closely related types of works and could plausibly refer to the same or overlapping structures. The funding years are consecutive, which could indicate either a continuation or a possible double funding. The evidence is complete and meets the rule's criteria for publishing.
