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 23IA0010 and 23IA0100 have near-identical descriptions about 128 m apart (funding year 2023; ₱9.90M, ₱4.82M). Worth checking whether they cover the same works. It is possible these are two segments of a larger flood control project that were bid out separately.

How this was checked

publish · confidence 0.85

Model: gpt-4.1

Prompt: v4.1

Checked: October 22, 2026

The two project titles are near-identical and refer to the same barangay and municipality, with no distinguishing markers such as phase, package, or different locations. The only differences are generic words ('structure', 'in', 'barangay'/ 'brgy'), which are not distinguishing per the rules. Both projects are in the same funding year, by the same contractor, and are only 128 meters apart. This fits the criteria for a potentially duplicate or overlapping project worth public attention.
