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 22OI0039 and 23OI0033 have near-identical descriptions about 238 m apart (funding years 2022, 2023; ₱49.00M, ₱49.00M). Worth checking whether they cover the same works. It is possible that the second project is a continuation or extension of the first, or covers additional works not specified in the title.

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 the word 'at' differing, and both refer to the same river and city without any distinguishing markers such as phase, package, or different locations. The projects are about 238 meters apart and funded in consecutive years, which fits the rule's criteria for a potentially duplicated or overlapping project. All necessary records and URLs are present.
