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 23DQ0054 and 23DQ0048 have near-identical descriptions about 24 m apart (funding year 2023; ₱4.65M, ₱4.70M). Worth checking whether they cover the same works. It is possible that the two contracts cover adjacent or slightly different sections of the same area, but the titles do not clearly distinguish them.

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, with only generic administrative words ('Barangay', 'City') present in one title but not the other. There are no phase, package, section, or place markers distinguishing them, and both are at Addas 1, San Nicolas II, Bacoor, Cavite, funded in the same year, by the same contractor, and only 24 meters apart. This fits the rule's criteria for a potentially duplicate or overlapping project. The evidence is complete and checkable.
